In the the figure above AC bisects BCD in the quadrilateral, the length of CD will be 6cm.

It should be noted that the longer diagonal is a perpendicular bisector of the shorter diagonal.

From the diagram given, the value of AD is 6cm. Therefore, according to the angle bisector theorem, the value of CD is 6cm as they're congruent.

So assuming this table contains all the zeroes of f(x) and all of them having a multiplicity of 0. This quadratic equation can be defined as

[tex]f(x) = a(x+2)(x-1)[/tex]. So if you look at the top where its f(-3) then f(-2) then f(-1) it appears to be increasing and then somewhere in between f(-1) and f(0) it has a turning point in which it starts decreasing. and then after f(1) it no longer outputs positive values and appears to be going towards negative infinity. So the interval in which f(x) is positive seems to be finite and using this table it appears to be at (-2, 1) and make sure to use parenthesis since at f(-2) and f(1) it's not positive, because 0 is not positive, so it's not included in the interval

Using proportions, it is found that it would take 6.4 days for 8 men to dig a trench of 360 meters long working at the same rate.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the rule of three is given as follows:

8 days - 15 men - 240 meters

x days - 18 men - 360 meters

The number of men is inverse proportional to the number of days, hence we divide 18 by 15 instead of 15 by 18, then:

[tex]\frac{8}{x} = \frac{18}{15} \times \frac{24}{36}[/tex]

[tex]\frac{8}{x} = \frac{6}{5} \times \frac{4}{6}[/tex]

[tex]\frac{8}{x} = \frac{5}{4}[/tex]

Answer:

(-3, -5) is not a solution of the equation 7x - 5y = 15

Step-by-step explanation:

1) Knowing that coordinates are given to us as (x, y), plug in the ordered pair into the equation. [tex]7(-3)-5(-5)=15[/tex]

2) Do PEMDAS on the left side of the equation

Answer:

Not a solution

Step-by-step explanation:

Hello!

We can determine if it's a solution by plugging in the x and y-values of the point into the equation. If both sides are equal to each other, then it is a solution.

-3 is the x-value and -5 is the y-value, since an ordered pari is written in the form of (x,y).

Since both sides are not equal to each other, (-3,-5) is not a solution.

By knowing the blood pressure and applying the quadratic formula, the age of a man whose normal blood pressure is 129 mm Hg is 40 years old.

In this problem we have a quadratic function that models the blood pressure as a function of age. As the latter is known, we must use the quadratic formula to determine the former:

129 = 0.006 · A² - 0.02 ·A + 120

0.006 · A² - 0.02 · A - 9 = 0

[tex]A = \frac{0.02 \pm \sqrt{0.006^{2}-4\cdot (0.006)\cdot (- 9)}}{2\cdot (0.006)}[/tex]

A = 1.667 + 38.733

A = 40

The change of displacement with respect to time is defined as speed. Velocity is a vector quantity. The instantaneous velocity at t = 2 is -12.

The change of displacement with respect to time is defined as Velocity. velocity is a vector quantity. It is a time-based component. Its standard unit is m/sec.

Given that the position of an object at time t is given by s(t) = 1 - 12t. Therefore, the velocity of the object can be written as,

V = ds/dt

   = d(1 - 12t)/dt

   = -12

s'(t) = -12

Now, the instantaneous velocity at t=2 is,

s'(2) = -12

The total cost of putting the posters on the wall is $25.

If the first poster on each end will be exactly even with the start of the wall, it means that after the two posters have been placed on either side of the wall, the total space left would be 10 feet (24 -  3 - 3 - 4 - 4).

After the first poster has been placed on both ends of the wall, a second poster would be placed on either ends of the wall. Total space now left is 4 feet (10 - 3 - 3). So there can only be four posters on the wall.

Total cost of 4 posters = 4 x $6.25 = $25

The remainder from the division of the algebraic equation is -53/8.

The remainder of the algebraic expression can be determined by using the long division method.

Given that:
[tex]\mathbf{f(x) = \dfrac{x^3 - 6x^2 + 3x - 1}{2x-3}}[/tex]

where:

Using the long division method, we have:

[tex]\mathbf{= \dfrac{x^2}{2} +\dfrac{-\dfrac{9x^2}{2}+3x -1 }{2x-3}}[/tex]

[tex]\mathbf{= \dfrac{x^2}{2}-\dfrac{9x}{4} +\dfrac{-\dfrac{-15x}{4}-1 }{2x-3}}[/tex]

[tex]\mathbf{= \dfrac{x^2}{2}-\dfrac{9x}{4} -\dfrac{15}{8}+\dfrac{-\dfrac{53}{8} }{2x-3}}[/tex]

[tex]\mathbf{= \dfrac{x^2}{2}-\dfrac{9x}{4} -\dfrac{15}{8}-\dfrac{53 }{8(2x-3)}}[/tex]

Step-by-step explanation:

So since it charges 4%, this means you need to find 4% of what you're transferring. To find x% of a number, you need to convert the percentage to a decimal, and then multiply it by the number you're trying to find x% of. So in this case 4%/100 = 0.04. Now take this decimal and multiply it by 2100, and this will give you 84. So the fee would be $84

Answer:

Step-by-step explanation:

20 months

Turn sentences into equation:

She deposits $225 every month after initial deposit of $2500 in first month

Equation: y = 2500 + (x - 1)225

where y represents total amount, x represents months

Use this equation to find at which month her account will have $6,775

2500 + (x - 1)225 = 6,775

(x - 1)225 = 6,775 - 2,500

(x - 1)225 = 4275

x - 1 = 19

x = 20

Thus, it will take 20 months when she have a total of $6,775.

Answer:

0.29287

Step-by-step explanation:

You want to use the binomial cumulative distribution function (binomcdf). The purpose of this function is that it allows you to obtain the probability of observing less than or equal to x successes in n trials, with the probability p of success on a single trial.

x in this case is 182, n is 200, and p is 0.9005. Essentially by inputting these values, we find the probability that out of 200 passengers with a 0.9005 chance of getting on the plane, that 182 or less show up.

This gives us P(x <= 182) = 0.70713. (You need your calculator for this step, input the values above in the binomcdf function)

We want to find the probability of more than 182 passengers showing up though, so it would be 1 - 0.70713 = 0.29287.

Thus the probability that when 200 reservations are accepted for the flight, there are more passengers than seats available is 0.29287.

Step-by-step explanation:

A rational number means that you are able to write the number as a fraction with integers in the numerator and the denominator.  An integers are the whole numbers and their opposites ...-3,-2,-1,0,1,2,3...

The square root of 4 is 2.  2 can be written 2/1 (an integer over and integer)

-square root of 2 cannot be written as an integer over an integer.  When this number is written as a decimal number it never repeats and it never terminates so it cannot be written as an integer over and integer.

-2/3 is written in the form of an integer over and integer.

1 can be written 1/1

9/8 is written as an integer over an integer.

The square root of  9/4 would be 3/2. (3/2)(3/2) = 9/4.

2.4 repeating can be written as an integer over an integer.  Any decimal that repeats or terminates can be written as an integer over and integer.  It actual happens to be 22/9.

The square root of 10 written as a decimal does not repeat or terminate so it is not rational.  Only perfect squares are rational.

Hey!

Your equation is -

[tex]x {}^{2} - 25 + 16 = 0[/tex]

[tex]x {}^{2} - 9 = 0[/tex]

We can write 9 as 3² (Why?) because it forms identity a² - b² = (a + b) (a - b) .

[tex]x {}^{2} - {3}^{2} = 0[/tex]

[tex](x - 3)(x + 3) = 0[/tex]

This gives the information that either,

x - 3 = 0 or x + 3 = 0

So, x = 3 or x = -3

Hope it helps, you may ask if you have any confusions ^-^

Answer:

x = 3,   x = -3

Step-by-step explanation:

x² - 25 + 16 = 0

⇒ x² - 9 = 0

• Add 9 to both sides:

⇒ x² = 9

• Square root both sides of equation:

x = [tex]\sqrt{9}[/tex]

x = ± 3

x = 3  and  x = -3
