Answers

Answer 1

Answer:

Answers and Steps are in Pictures.

Answer 2

Answer:

∠ R ≈ 36.9

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosR = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , then

∠ R = [tex]cos^{-1}[/tex] ([tex]\frac{8}{10}[/tex] ) ≈ 36.9 (to 1 dec. place )

There is a cylinder with a height of 8 units and a volume of 72 cubic units. What is the radius of the cylinder?

Answers

Answer:

Radius of the cylinder = 1.69 units

Step-by-step explanation:

Volume of a cylinder is given by the expression,

Volume = Area of the circular base × Height of the cylinder

Area of the circular base = πr²

Here, r = Radius of the circular base

Volume of the cylinder = πr²h

By substituting the values given in the question,

72 = π(r)²8

r² = [tex]\frac{9}{\pi }[/tex]

r² = 2.865

r = 1.692

r = 1.69 units

The first 4 terms of a geometric sequence are 2, 6, 18, 54. Part A: Find the common ratio. Remember the common ratio is the number that is multiplied to each value to get the next number. Part B: Find the next 3 values in the geometric sequence Come up with your own geometric sequence and identify the common ratio.

Answers

Answer:

Common ratio is 3

The three terms are 162, 486, 1458

Step-by-step explanation:

Given: The first 4 terms of a sequence are [tex]2,6,18,54[/tex]

To find:

A. the common ratio

B. the next 3 values in the geometric sequence

Solution:

Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.

[tex]\frac{6}{2}=3\\\\\frac{18}{6}=3\\\\\frac{54}{18}=3[/tex]

So, the common ratio is [tex]3[/tex]

The next three values are as follows:

[tex]54(3)=162\\162(3)=486\\486(3)=1458[/tex]

Step-by-step explanation:

we are given a function that represents the growth of the population

we want to figure out what the population will be in 2015

since the function is for the population growth after 2009 so the t should be

2015-20096

now plug in the value of t:

[tex] \displaystyle p(6) = 50 {e}^{0.85 \times 6} [/tex]

simplify which yields:

How does the graph of an inverse function compare to the original function?
A. The inverse function is the original function reflected over the x-axis
B. The inverse function is the original function reflected over y=x
C. The inverse function is the original function reflected over y=-x
D. The inverse function is the original function reflected over the y-axis

Answers

The inverse function is the original function reflected over y=x option (B) is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a statement:

The graph of an inverse function compare to the original function:

As we know, every function with domain real numbers can be plotted on graph paper or a coordinate plane.

Let f(x) = ax + b

y =ax + b

a and b are the real numbers

To find the inverse of a function interchange the value of x and y

f⁻¹ = x = ay + b

If we plot the above two functions we will see that f(x) is the mirror image of f⁻¹ over the line y = x.

Thus, the inverse function is the original function reflected over y=x option (B) is correct.
