Answer:

31.5

Step-by-step explanation:

Assuming that the lowest point and the highest point on the Ferris wheel are opposite each other, the difference of height will be the distance between the two points, and thus, the distance across fo the Ferris wheel. Divide this value by (2) to find the radius of the strucutre.

75 - 12

= 63

63 / 2

= 31.5

Please answer ASAP. The question is down below.

Butoxors [25]

Answer: 1) c 2) d

<u>Step-by-step explanation:</u>

Use Pythagorean Theorem to find the hypotenuse (r): x² + y² = r²

Given: x = 2, y = 6

2² + 6² = r²

4 + 36 = r²

40 = r²

$\sqrt{40}=r$

$\sin \theta=\dfrac{y}{r}\quad =\large\boxed{\dfrac{6}{\sqrt{40}}}\quad \rightarrow \dfrac{6}{2\sqrt{10}}\quad \rightarrow \dfrac{3}{\sqrt{10}}$

*******************************************************************************************

$\sin \theta = \dfrac{opposite(y)}{hypotenuse(r)}\quad =\dfrac{12}{20}\quad \rightarrow \dfrac{3}{5}\quad \rightarrow \large\boxed{0.6}\\\\\\\cos \theta = \dfrac{adjacent(x)}{hypotenuse(r)}\quad =\dfrac{16}{20}\quad \rightarrow \dfrac{4}{5}\quad \rightarrow \large\boxed{0.8}$

Let f(x)=4x^2-3 and g(x)=-x^2+2.Find f+g and state the domain. Then evaluate the sum when x=2

Whitepunk [10]

Answer:

f+g = 3x^2-1. domain = all real numbers. then plug in two wherever there is an x.

f(x)=4*2^2-3, which equals 13

g(x)= -2^2+2, which equals -2

add

f+g when x=2 is 11

Given the system of equations:

mr_godi [17]

Answer:

Step-by-step explanation:

Given the system of equations:

2x + 3y = 15

X + 3y = 0

What is x?

2x + 3y = 15

X + 3y = 0 subtract the bottom equation fron the top one

2x - x + 3y - 3y = 15 - 0 see how the 3y - 3y equates to zero

2x - x = 15

x = 15 Now for extra credit what is y?

X + 3y = 0

15 + 3y = 0

15 - 15 + 3y = 0 - 15

3y = -15

3y/3 = -15/3

y = -5

-15

-5
