In triangle ABC acute angles are in the ratio 5:1, i.e.

Answers

Answer 1

Answer:

The quen is as following:

ABC is a right triangle at C,

Acute angles are in the ratio 5:1, i.e. ∠BAC : ∠ABC = 5:1

If CH is an altitude to AB and CL is an angle bisector of ∠ACB, find m∠HCL.

The solution is:  m∠HCL = 30°

Step-by-step explanation:

See the attached figure.

∵The triangle is right at C   ∴∠C = 90°

∴∠A + ∠B = 90° ⇒(1)

∵ Acute angles are in the ratio 5:1, i.e. ∠BAC : ∠ABC = 5:1

∴∠A = 5 times ∠B

Substitute at (1)

∴ 5 ∠B + ∠B = 90° ⇒⇒⇒ ∴∠B = 15°  and ∠A = 75°

∵CL is an angle bisector of ∠ACB

∴ ∠ACL = 90°/2 = 45°

∵ CH is an altitude to AB ⇒ ∠CHA = 90°

At the triangle AHC:

∠ACH = 180° - (∠CHA + ∠CAH) = 180° - (90° + 75°) = 15°

∴ ∠HCL = ∠ACL - ∠ACH = 45° - 15° = 30°

Solution:

Take any two points on container 1.

Let the points are (10, 2) and (20, 4).

m = (y2 - y1) / ( x2 - x1 )

   = ( 4 - 2 ) / ( 20 - 10 )

   = 2/ 10

   = 1/ 5

Rate of change for container 1 is .

Take any two points on container 2.

Let the points are (5, 2) and (10, 4).

m = (y2 - y1) / ( x2 - x1 )

a. (-4,5)
b. (4,-1)
c. (-10, 3)

Answers

To solve the given system of equations using elimination, we can add the two equations together to eliminate one of the variables. Doing this, we get 3x + 9y + (-10x - 6y) = 33 + (-14), which simplifies to -7x + 3y = 19. We can then solve for y by dividing both sides of the equation by 3, giving us y = 19/3 = 6.33. We can substitute this value for y in either of the original equations to solve for x. For example, if we substitute 6.33 for y in the first equation, we get 3x + 9 * 6.33 = 33, which simplifies to 3x = 3.67. Dividing both sides of the equation by 3, we get x = 1.22. Therefore, the solution of the system is (1.22, 6.33), which is approximately (1, 6). The answer choice that is closest to this solution is (d) (-1, 4). Thus, the solution of the system is (-1, 4).

It will take _______ years for this investment to triple in value.

Answers

Answer:

It will take 41.7 years for this investment to triple in value.

Step-by-step explanation:

Here is the formula for simple interest

[tex]A=P(1+rt)[/tex]

Lets solve for [tex]t[/tex].

Divide both sides by [tex]P[/tex].

[tex]\frac{A}{P}=rt+1[/tex]

Subtract 1 from both sides.

[tex]\frac{A}{P}-1=rt[/tex]

Divide both sides by [tex]r[/tex].

[tex]\frac{\frac{A}{P}-1}{r} =t[/tex]

To write [tex]-1[/tex] as a fraction with a common denominator, multiply by [tex]\frac{P}{P}[/tex] .

[tex]\frac{\frac{A}{P}-1*\frac{P}{P}}{r} =t[/tex]

[tex]\frac{\frac{A}{P}*\frac{-P}{P}}{r} =t[/tex]

Combine the numerators over the common denominator.

[tex]\frac{\frac{A-P}{P} }{r} =t[/tex]

Multiply the numerator by the reciprocal of the denominator.

[tex]t=\frac{A-P}{Pr}[/tex]

We need to find what amount is triple his money.

[tex]3800*3=11400[/tex]

[tex]A=11400[/tex]

Substitute our numbers into the equation for [tex]t[/tex].

[tex]t=\frac{11400-3800}{3800*0.048}[/tex]

Factor 3800 out of 11400.

[tex]t=\frac{3800*3-3800}{3800*0.048}[/tex]

Factor 3800 out of −3800.

Factor 3800 out of [tex]3800*3-3800*-1[/tex].

[tex]t=\frac{3800*(3-1)}{3800*0.048}[/tex]

Cancel the common factor of 3800.

a. Use the points (1, 226.9) and (4, 275.2) to write an equation for the line of fit in slope-intercept form, where x is the number of years since 2010 and y is the median price in thousands of dollars. what will be the approximate price by 2025?

Answers

The Equation of line is y= 16.1x + 210. 8.

The approximate price by 2025 is 452.3.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

The points are (1, 226.9) and (4, 275.2).

So, Slope for line

m = ( 275.2- 226.9)/( 4-1)

m = 48.3/ 3

m= 16.1

Now, using the slope- intercept form

y= mx+ b

y = 16.1x + b

Now, x= 1 and y= 226.9

By, y = 16.1 + x

226.9 = 16.1(1)+ b

b= 210.8

So, the equation of line is y= 16.1x + 210. 8

Now,  x is the number of years since 2010 and by 2025

x= 2025 - 2010 = 15

Then, the approximate price by 2025

y= 16.1(15) + 210.8

y= 452.3

Hence, the approximate price by 2025 is 452.3.

(a) A king is drawn
(b) The card drawn is a king or a queen.
(c) The card drawn is a diamond.
(d) The card drawn is a black card.

Answers

The probability of drawing a king, a king or queen, a diamond, or a black card from a deck of 52 cards is 1/52, 4/52, 13/52, and 26/52, respectively.

(a) The probability that a king is drawn is 1/52, since there is only one king in the deck and 52 total cards. This means that if we draw one card from the deck, the probability that it will be a king is 1/52.

(b) The probability that a king or a queen is drawn is 4/52, since there are four kings and queens in the deck and 52 total cards. This means that if we draw one card from the deck, the probability that it will be a king or queen is 4/52.

(c) The probability that a diamond is drawn is 13/52, since there are 13 diamonds in the deck and 52 total cards. This means that if we draw one card from the deck, the probability that it will be a diamond is 13/52.

(d) The probability that a black card is drawn is 26/52, since there are 26 black cards in the deck and 52 total cards. This means that if we draw one card from the deck, the probability that it will be a black card is 26/52.

     $1526.49:  10 yr

(b)  See below.

(c)  x = 705

     more, $705, longer it will take

Step-by-step explanation:

Given equation:

[tex]t=16.708 \ln \left(\dfrac{x}{x-705}\right)[/tex]

where:

t = term of the mortgage (in years)x = monthly payment plan (in dollars)

Part (a)

[tex]\begin{aligned}x=897.72 \implies t& =16.708 \ln \left(\dfrac{897.72}{897.72-705}\right)\\& =16.708 \ln \left(4.65815691...\right)\\&=16.708(1.53861985...)\\&=25.70726...\\&=26\; \rm years\end{aligned}[/tex]

[tex]\begin{aligned}x=1526.49 \implies t& =16.708 \ln \left(\dfrac{1526.49}{1526.49-705}\right)\\& =16.708 \ln \left(1.85819669...\right)\\& =16.708(0.619606496...)\\&=10.352385...\\&=10 \; \rm years\end{aligned}[/tex]

Part (b)

To approximate the total amounts paid (in dollars) over the term of the mortgage, multiply the monthly payment by the term.

Please note I have provided two calculations per monthly payment:

(1) by using the exact term, and (2) using the rounded term from part (a).

[tex]\implies \$897.72 \times 25.7072605... \times 12 =\$276935.06[/tex]

[tex]\implies \$897.72 \times 26 \times 12=\$280088.64[/tex]

[tex]\implies \$1526.49 \times 10.3523853... \times 12=\$189633.75[/tex]

[tex]\implies \$1526.49 \times 10 \times 12 =\$183178.80[/tex]

To calculate the amount of interest costs (in dollars) in each case, subtract $150,000 from the total amounts paid:

[tex]\$897.72\implies 276935.06-150000=\$126935.06[/tex]

[tex]\$897.72 \implies 280088.64-150000=\$130088.64[/tex]

[tex]\$1526.49 \implies 189633.75-150000=\$39633.75[/tex]

[tex]\$1526.49\implies 183178.80-150000=\$33178.80[/tex]

Part (c)

The natural logarithm of a negative number cannot be taken.

Therefore, x > 705.

So the vertical asymptote for the model is:

x = 705

The monthly payment must be more than $705, and the closer to this value the payment is, the longer it will take to pay off the mortgage.

Find the point on the line 3x + y = 8 that is closest to the point
(−3, 1)

Answers

The point on the line 3x + y = 8 that is closest to the point (-3, 1) is (1.8, 2.6).

What is Quadratic Equations?

Quadratic equations are equations of the form a x² + b x + c = 0 where a, b and c are real numbers.

Given line is,

3x + y = 8 ⇒ y = -3x + 8

So we have any point (x, -3x + 8).

We have to find a point (x, -3x + 8) such that distance of this point from (-3, 1) is minimum.

Distance between (-3, 1) and (x, -3x + 8) = √[(x - -3)² + (-3x + 8 - 1)²]

                                                                  = √[(x + 3)² + (-3x + 7)²]

                                                                  = √(x² + 6x + 9 + 9x² - 42x + 49)

                                                                  = √(10x² - 36x + 58)

So the distance between (-3, 1) and (x, -3x + 8) is √(10x² - 36x + 58) should be minimum.

We minimize the function f(x) = 10x² - 36x + 58.

A quadratic function represents the equation of a parabola.

Coefficient of x² is positive, so parabola opens upward. So we will be having the minimum value.

Minimum value at the point x = -b / 2a for the quadratic equation a x² + b x + c.

Minimum value is at x = - (-36) / (2 × 10) = 36/20 = 9/5 = 1.8.

To find the y coordinate,

y = -3x + 8 = 2.6

So the required point is (1.8, 2.6).

Hence the point on the line closest to the point (-3, 1) is (1.8, 2.6)

Answers

Ss, variance and the standard deviation for the population of scores is 2.83 and 8 respectively

What is standard deviation and variance?

Standard deviation is a measure of the distribution of statistical data, whereas variance is a measure of how data points differ from the mean. The fundamental distinction between the two is that although the variance is expressed in squared units, the standard deviation is expressed in the same units as the data's mean.

Given,

SS = 40

Variance = 10

Standard Deviation = 3.16

Using Population Variance Formula :

= [tex]\frac{1}{n}[/tex]∑( x-xbar)²  where i is 1

For the complete solution see the attachment of table

A high heart rate, especially in combination with a large projected deviation, can be a sign of a potential health problem or underlying condition that requires immediate medical attention.

In contrast, Kulazhi has a lower heart rate and smaller projected deviation, which may indicate that their cardiovascular system is functioning normally. However, it is still important to monitor and track their heart rate over time to ensure that it remains within a healthy range.

If I were a doctor, the immediate patient I would treat is; Kundaval because he has a higher projected deviation and a faster heart rate.

What is the standard deviation?

Instead of computation or experimentation, the standard deviation is an abstract concept based on observation.

A metric that is used to express the amount of variation or dispersion in a group of data is the standard deviation, which is also represented by the Greek letter sigma(σ).

To put it another way, it specifies the degree to which the members of a data group differ from the group's average value.

Given

The sum of heart rate readings taken five times for Kundaval is 400

The sum of heart rate readings taken five times for  Kulazhi is 360

and their projected deviation are 3.16 and 2.0,

Now, the standard deviation is a measure of how dispersed the data are in relation to the mean, whereas the mean simply refers to the average of a set of given data.

As a result, as a doctor, I would prioritize treating the patient whose heart rate and projected deviation are higher. As a result, we would conclude that Kundaval, with a projected deviation of 3.16 and a sum of 400 heart rate readings, should be treated first.

Therefore, The immediate patient I would treat if I were a doctor is; Kundaval because he has a faster heart rate and a higher projected deviation.

Replace the loading system acting on
the beam by an equivalent resultant
force and couple moment at point O.

Answers

The answers are a) FR = 365 N b) u = 70.8° d and c) (MR)O = 2364 N m (counterclockwise)

What is resultant force?

When an object is subject to several forces, the resultant force is the force that alone produces the same acceleration as all those forces.

Given is a figure, we need to find equivalent resultant force and couple moment at point O

Equivalent Resultant Force And Couple Moment At O.

+→ (FR)x = ΣFx; (FR)x = 600 cos 60° - 455(12 / 13)

= -120 N = 120 N ←

+ ↑ (FR)y = ΣFy; (FR)y = 455(5/13) - 600 sin 60° = -344.62 N = 344.62 N ↓

As indicated in Fig (attached)

a) FR = √F(R)x²+F(R)y²

= √2120² + 344.62² = 364.91 N = 365 N

And

b) θ = tan-1{(FR)y / (FR)x}

= tan-1 {344.62/120}

= 70.80°

Also,

c) a+(MR)O = ΣMO; (MR)O = 455(12/13)(2) + 600 cos 60° (0.75) + 600 sin 60° (2.5)

If a share of a stock jumped from $9 to $25, what was the percent increase of this stock (rounded to the
nearest tenth)?

Answers

Answer: 177.8

Step-by-step explanation: To find the percent increase, we have to use this formula:

New value-old value/ old value x 100

So, following this formula, we would do 25-9, which, is 16, divided by 9. That would be 1.777... So now let's round that to 1.78, so 1.78 x 100 = 177.8. I hope this helped.

Determine if the following equation has one, none, or many solutions.
2(2x+-1)=4x-4

Answers

To determine whether an equation has one, none, or many solutions, we need to solve the equation for the variable. In the case of the equation 2(2x+-1)=4x-4, we can solve for x by first distributing the 2 on the left-hand side of the equation:

22x+2-1 = 4x - 4

This gives us the following equation:

4x-2 = 4x - 4

We can then subtract 4x from both sides of the equation to obtain:

-2 = -4

This equation does not have any solutions, because the left-hand side and the right-hand side are not equal. Therefore, the original equation has no solutions.

Answer: no solutions

Though 70% of women with children younger than 18 years participate in the labor force, society still upholds the stay-at-home mother as the traditional model. Some believe that employment distracts mothers from their parenting role, affecting the well-being of children. In the GSS 2014, respondents were asked to indicate their level of agreement to the statement: "A working mother hurts children". Of the 435 male respondents who answered the question, 18% strongly agreed that a working mother does not hurt children. a, What is the 90% confidence interval for this statistic for males? b. Of the 566 respondents who answered the question, 40% strongly agree that a working mother does not hurt children. What is the 90% confidence level for this statistic?

Answers

a) The 90% confidence interval for this statistic for males is of: (0.1497, 0.2103).

b) The 90% confidence level for this statistic is of: (0.3661, 0.4339).

What is a confidence interval of proportions?

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.

The confidence level is of 90%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.9}{2} = 0.95[/tex], so the critical value is z = 1.645.

For males, the parameters are given as follows:

[tex]\pi = 0.18, n = 435[/tex]

Hence the lower bound of the interval is given as follows:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.18 - 1.645\sqrt{\frac{0.18(0.82)}{435}} = 0.1497[/tex]

The upper bound of the interval is of:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.18 + 1.645\sqrt{\frac{0.18(0.82)}{435}} = 0.2103[/tex]

For the statistic, the parameters are given as follows:

[tex]\pi = 0.4, n = 566[/tex]

Hence the lower bound of the interval is given as follows:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 - 1.645\sqrt{\frac{0.4(0.6)}{566}} = 0.3661[/tex]

The upper bound of the interval is of:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 + 1.645\sqrt{\frac{0.4(0.6)}{566}} = 0.4339[/tex]
