D co 43°

Answers

Answer 1

Option (A) cos 47° is equal to sin 43°.

What is cos in trigonometry ?

The cos meaning in trigonometry defines the cosine of an angle. This angle is an acute angle in a right angled triangle, which is considered to find the ratios. Thus, cosine of an angle, in a right-triangle, is equal to the ratio of adjacent side of that angle and hypotenuse of the triangle.

What is sin in trigonometry ?

In trigonometry, the sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle. The sine function is used to find the unknown angle or sides of a right triangle.

Have given,

cos 47°,

We know that cos x = sin (90 - x),

Thus cos 47° = sin (90 - 47)

cos 47° = sin 43°

Therefore, cos 47° is equal to sin 43°.

Determine the domain and range for the function below.

Answers

Answer:

Domain: (-∞, ∞); Range: [1, ∞)

Step-by-step explanation:

Domain is the set/interval of x-values that the function spans while the range is the set or interval of y-values that the function spans.

Domain

We can see that the arrows point towards negative and positive infinity for x and also see there are no holes or asymptotes for this graph. Therefore, the domain is (-∞, ∞) or {x | x is any real number}

Range

We can see that the arrows both point towards infinity for y-values and that the lowest y-value this graph touches is y = 1 (inclusive, meaning this y-value is included in the range). Thus, the range is [1, ∞) or {y | y ≥ 1}

Graph the line through the given point with the given slope.

(0, 5), m = - 5

(basically what coordinate points would there be?)

Answers

Answer:

The equation would be

y =-5x + 5

Step-by-step explanation:

Use the x of 0 from the point given (0,5)

Use the y of 5 from the point given (0,5)

Use the slope that is given: -5

Use all of the above to solve for the y-intercept (b).

y = mx + b

5 = -5(0) + b

5 = 0 + b

5 = b

y =mx + b

y = -5x + 5

In the graph, the line crosses the y axis at (0,5) . The is the y -intercept or the "b" of the equation.

From that points move down 5 and one to the right.  This is the slope.  Once we have two points we can draw a line.

Why is 1 not a square number?

What does Squaring mean ?

In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9.

When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

How do we get negative infinity?

Answers

Negative infinity is obtained by taking the limit of a decreasing sequence of negative real numbers as they approach negative infinity.

Negative infinity is an abstract concept that is used to represent a value that is less than the lowest possible number.  To get negative infinity, one must take the limit of a decreasing sequence of negative real numbers. This means that the sequence of numbers must get closer and closer to negative infinity as it continues to decrease. For example, if you take the sequence of numbers -1, -2, -3, -4, -5, -6, and so on, the limit of this sequence is -∞. As the sequence continues to decrease, it eventually reaches a point where the numbers become so small that they cannot be measured. At this point, the limit of the sequence is -∞.

What type of discontinuity is a hole?

Answers

A removable discontinuity is when a function has an isolated point where it is not defined, and the function can be made continuous by removing that point. A hole is an example of a removable discontinuity.

In mathematics, a discontinuity is a point or set of points where a function does not behave as expected or fails to exist. There are three types of discontinuities: removable discontinuities, jump discontinuities, and infinite discontinuities. A removable discontinuity is when a function has an isolated point where it is not defined, and the function can be made continuous by removing that point. In other words, the function can be made continuous by “filling in” the discontinuity. An example of a removable discontinuity is a hole, where the graph has a gap that can be filled in. Jump discontinuities occur when the left-hand and right-hand limits of the function do not agree at a point, and the function “jumps” from one value to another at that point. An example of a jump discontinuity is a cusp, where the graph has a sharp point. Finally, an infinite discontinuity is when the function does not exist at a point, such as a vertical asymptote. In all three cases, the discontinuity can be easily identified by looking at the graph of the function.

Answer:

Length of the base = 15 cm

Volume = 1125√2 cm³ = 1590.99 cm³ (2 d.p.)

Step-by-step explanation:

If the lateral surface area (LSA) of the pyramid is three times the base area (BA):

[tex]\implies a \sqrt{a^2+4h^2}=3a^2[/tex]

Rearrange the equation to isolate h²:

[tex]\implies \sqrt{a^2+4h^2}=3a[/tex]

[tex]\implies (\sqrt{a^2+4h^2})^2=(3a)^2[/tex]

[tex]\implies a^2+4h^2=9a^2[/tex]

[tex]\implies 4h^2=8a^2[/tex]

[tex]\implies h^2=2a^2[/tex]

[tex]\boxed{\begin{minipage}{6.6cm}\underline{Total Surface Area of a square pyramid}\\\\$SA=a^2+a \sqrt{a^2+4h^2}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the base edge \\\phantom{ww}$\bullet$ $h$ is the height\\\end{minipage}}[/tex]

Given:

SA = 900 cm²h² = 2a²

Substitute these values into the formula for the total surface area and solve for a:

[tex]\implies a^2+a\sqrt{a^2+4(2a^2)}=900[/tex]

[tex]\implies a^2+a\sqrt{a^2+8a^2}=900[/tex]

[tex]\implies a^2+a\sqrt{9a^2}=900[/tex]

[tex]\implies a^2+a(3a)=900[/tex]

[tex]\implies a^2+3a^2=900[/tex]

[tex]\implies 4a^2=900[/tex]

[tex]\implies a^2=225[/tex]

[tex]\implies a=15[/tex]

Therefore, the length of the base of the square based pyramid is:

a = 15 cm

To find the height (h), substitute the found value of a into the formula for h² and solve for h:

[tex]\implies h^2=2(15)^2[/tex]

[tex]\implies \sqrt{h^2}=\sqrt{2(15)^2}[/tex]

[tex]\implies h=\sqrt{2}\sqrt{(15)^2}[/tex]

[tex]\implies h=15\sqrt{2}[/tex]

Therefore, the height of the square based pyramid is:

h = 15√2 cm

[tex]\boxed{\begin{minipage}{5cm}\underline{Volume of a square pyramid}\\\\$V=\dfrac{1}{3}a^2h$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the base edge \\\phantom{ww}$\bullet$ $h$ is the height\\\end{minipage}}[/tex]

Given:

a = 15h = 15√2

Substitute the values into the formula and solve for volume:

[tex]\implies V=\dfrac{1}{3}(15)^2 \cdot 15\sqrt{2}[/tex]

[tex]\implies V=\dfrac{225}{3} \cdot 15\sqrt{2}[/tex]

[tex]\implies V=75\cdot 15\sqrt{2}[/tex]

[tex]\implies V=1125\sqrt{2}[/tex]

Therefore, the volume of the square based pyramid is:

The equation may be used to predict how much of the chemical is still present after t years, measured in ounces.

y=1800e -0.00052t

In the equation above, we substitute y = 80 ounce to obtain the time.

80= 1800e -0.00052t

80/1800=e -0.00052t

2/45= e -000.52t

Considering both ends of the aforementioned equation

In(2/45)= In(e -000.52t)

In(2)-In(45)= In(e -000.52)

0.3010-1.653= -000.52t

-1.352= -000.52t

dividing by 000.52 on both side

1.352/000.52= t

t= 2.622 years

Evaluate the quantity of x cubed minus 2x squared plus 3x minus 7 end quantity divided by the quantity of x minus 1 end quantity period.

Answers

Our final resulting answer will be -5.

To calculate the remainder, first divide the polynomials.

Set up the polynomials to be divided. if there is not a term for every exponent, insert one with a value of 0.

[tex]\sqrt[x-1]{x^{3}-2x^{2} +3x-7 }[/tex]

Divide the highest order term in the dividend [tex]x^{3}[/tex] by the highest order term in divisor x.

Multiply the new quotient term by the divisor.

The expression needs to be subtracted from the dividend, so change all the signs [tex]x^{3}[/tex]+[tex]x^{2}[/tex].

After changing the signs, add the last dividend from the multiplied polynomials to find the new dividend.

Pull the next terms from the original dividend down into the current dividend.

Divide the highest order term in the dividend -[tex]x^{2}[/tex] by the highest order term in divisor x.

Multiply the new quotient term by the divisor.

The expression needs to be subtracted from the dividend, so change all the signs in -[tex]x^{2}[/tex]-x.

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

Pull the next terms from the original dividend down into the current dividend.

Divide the highest order term in the dividend 2x by the highest order in divisor x.

Multiply the new quotient term by the divisor.

The expression needs to be subtracted from the dividend, so change all the signs in -2x+2.

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

The final answer is the quotient plus the remainder over the divisor.

[tex]x^{2}[/tex]-x+2-[tex]\frac{5}{x-1}[/tex]

Since the last term in the resulting expression is a fraction, the numerator of the fraction is the remainder.

So, our final answer will be -5.

What mode of observation is 5'7 8?

Answers

The mode for a particular set of observations is 5 since it occurs the majority of the time.

What is mode?

The mode formula is described in statistics as the formula for calculating the mode of a given collection of data. The value that occurs most frequently in a particular set is referred to as the mode, and the mode differs across grouped and ungrouped data sets. The mode may be calculated quite easily. Put all of the numbers in a given set in order, either lowest to highest or highest to lowest, and then count how many times each number appears in the set. The mode is the one that appears the most.

Here,

given set of observation:

5, 7, 8, 5, 7, 6, 9, 5, 10, 6

Mode is the number which occurs the highest time.

So here 5 occurs the highest times(3 times).

So,5 is the mode.

The mode for given set of observation is 5 as it occurs most time.

Describe a real world situation that could be modeled by the expression Y equals 1/20 XP transcribe what is

Answers

The required real-world situation has been written in the solution part which could be modeled by the expression Y equals 1/20 XP.

A real-world situation that could be modeled by the expression Y = 1/20XP is the relationship between the distance a person runs and the number of calories they burn.

In this situation, Y represents the number of calories burned and X represents the distance run in miles. The constant 1/20 represents the rate at which calories are burned per mile.

For example, if a person runs 5 miles, we can substitute 5 for X in the expression to find the number of calories they burn:

Y = 1/20 × 5X

Y = 1/4

Thus, the person burns 1/4 calorie for every mile they run.

The area of shaded region of standard normal distribution is 0.1292

what is standard normal distribution?

A unique type of normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution, or z-distribution.

Any normal distribution can be transformed into the common normal distribution by converting the individual values into z-scores. Z-scores indicate the number of standard deviations that each value in a z-distribution is from the mean.

solution:

For - 3.39 to 0

The standard deviation value is : 0.00035

For 0 to 1.13

The standard deviation value is : 0.3708
