Answer:

Step-by-step explanation:

Use the SOH-CAH-TOA method.

We are given an angle (37°).

We know a side that is opposite of the angle.And we are trying to find the hypotenuse.

So we use SOH

[tex] \sin(x) = \frac{o}{h} [/tex]

[tex] \sin(37) = \frac{0.6}{h} [/tex]

Isolate h

[tex]h = \frac{0.6}{ \sin(37) } [/tex]

Which gives us 1.

So the answer is 1.

Step-by-step explanation:

The  functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is  A = 500(1.1)^4

In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.

given:

P= $500

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 500.00[tex](1 + 0.1/1)(1)^4[/tex]

A = 500.00[tex](1.1)^4[/tex]

A = $732.05

Hence, the functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is  A = 500(1.1)^4

Answer:

-2/9

Step-by-step explanation:

The slope of the line passing through the given points is  [tex]\frac{2}{-9}[/tex]

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given are two points (2, 6) and (-7, 8) from which a line passes. We need to find the slope of the line.

We know that, the slope of a line passing through points (x₁, y₁) and (x₂, y₂) = (y₂-y₁) / (x₂-x₁)

In the given points, y₂ = 8, y₁ = 6, x₂ = -7 and x₁ = 2

Therefore, the slope of line = 8-6 / -7-2 = [tex]\frac{2}{-9}[/tex]

Hence, the slope of the line passing through the given points is  [tex]\frac{2}{-9}[/tex]

Answer: D

Step-by-step explanation:

To compare the two lines, we want to a=make sure that they are in the same form.

3y-x=-7           [add both sides by x]

3y=x-7            [divide both sides by 3]

y=1/3x-7

Now that the equations are in the same form, we can compare them.

In order for the equations to have the same y-intercept, the "b" must be the same. The y-intercept for the first equation is -4, while the y-intercept for the second equation is -7. Therefore, A is not the answer.

If the lines are parallel, they must have the same slope. Parallel lines NEVER touch or cross, hence the slope has to be the same. The slope for the first equation is -13, while the slope for the second equation is 1/3. Therefore, B is not the answer.

We know that E is not the answer because the paragraph above proved that the slope are not equal.

We also know that the equations do not represent the same line. If they are the same line, the equations would be identical.

We know that D is the correct answer. A system of linear equaitons can only have ONE solution. We set the equations equal to each other to find the solution. The intersection point is the solution.

Therefore, we know that D is the right answer.

The greatest common factor of 42 and 96 is 6 so, option A is correct.

The biggest positive number that divides each of the two or more non-zero integers is known as the greatest common divisor.

Given:

The two numbers are 42 and 96,

Factorize the numbers as shown below,

42 = 2 × 3 × 7

96 = 2 × 2 × 2 × 2 × 2 × 3

Calculate the GCF as shown below,

GCF = 2 × 3

GCF = 6

Thus, the GCF is 6.

Answer:

20

Step-by-step explanation

use the formula a²+b²=c²

since a=21 and c=29 you need to solve for b

Put 21 in for a and 29 in for c

21²+b²=29²

21²=441

29²=841

so then the equation would be 441+b²=841

subtract both sides by 441

then you have b²=400

now just find the square root of 400

√b²=√400

b=20

Answer:

Step-by-step explanation:

The length of the rectangle is 18 cm, and the width is 24 cm as per the concept of perimeter.

Let the length of the rectangle be 3x and the width be 4x, where x is a common factor.

The perimeter of a rectangle is given by the formula:

Perimeter = 2 × (Length + Width)

Given that the perimeter is 84 cm, we can write the equation as:

84 = 2 × (3x + 4x)

Now, let's solve for x:

84 = 2 × 7x

42 = 7x

x = 42 / 7

x = 6

Now that we have the value of x, we can find the length and width of the rectangle:

Length = 3x = 3 × 6

           = 18 cm

Width = 4x = 4 × 6

          = 24 cm

Therefore, the length of the rectangle is 18 cm, and the width is 24 cm. The length and width are in the ratio 3:4, and the perimeter of the rectangle is indeed 84 cm.

Using opposite by the same vertex and supplementary angles, it is found that the measure of angle 4 is of 66º.

In this problem, angles 5 and 7 are opposite by the same vertex, hence:

m<7 = m<5 = 114º.

Angles 4 and 5 are supplementary, hence:

m<4 + m<5 = 180º.

m<4 = 66º.

The measure of angle 4 is of 66º.

Answer:

Choice C

Step-by-step explanation:

We are given the function:

[tex]\displaystyle \large{f(x)=3x+5}[/tex]

Let [tex]\displaystyle \large{y=f(x)}[/tex] therefore:

[tex]\displaystyle \large{y=3x+5}[/tex]

To find an inverse of function, swap the position of x and y:

[tex]\displaystyle \large{x=3y+5}[/tex]

Then solve or simplify the equation in term of y:

[tex]\displaystyle \large{x-5=3y}\\\displaystyle \large{\frac{x-5}{3}=y}\\\displaystyle \large{y=\frac{1}{3}x-\frac{5}{3}}[/tex]

Therefore, the answer is choice C.

__________________________________________________________

Summary

An inverse function is a function that swaps the position of domain and range, defined as notation [tex]\displaystyle \large{f^{-1}(x)}[/tex] or [tex]\displaystyle \large{y^{-1}}[/tex] generally. When finding an inverse function, make sure to swap position of range and domain, if given the interval.

Only one-to-one functions may have an inverse — multiple-to-one can not have an inverse such as quadratic function or any even-degree polynomial functions.
