Find (f ∘ g)(4) when f(x) = -5x - 7 and g(x) = -6x 2 + 9x + 9.
mr_godi [17]

Answer:

\boxed{\sf \ \ \ 248 \ \ \ }

Step-by-step explanation:

Hello,

(fog)(4)=f(g(4)) \ \ \ and \ \ \ g(4)=-6*4^2+9*4+9=-51 \ \ so\\(fog)(4)=f(-51)=-5*(-51)-7=255-7=248

hope this helps

A circle is divided into 18 equal parts. How many degrees is the angle for each part? How many degrees is the angle for 5parts?
vlada-n [284]

Step-by-step explanation:

A circle has 360 degrees so 360/18= 20

For the 2nd question: 360/5=72

Help this is due tomorrow please! Carter has 88 feet of fencing to enclose a dog pen in his yard. He is trying to decide whether
svet-max [94.6K]
<h3>Answer:</h3>

The circle makes the larger area

The difference in the two areas is roughly 132.2479 square feet.

=================================================

Explanation:

If Carter decides to go for a circle, then 88 is the circumference, which is the distance around the circle (aka perimeter of the circle).

Use this to find the radius needed

C = 2*pi*r

r = C/(2pi)

r = 88/(2pi)

r = 44/pi

I'll leave it in exact form rather than approximate it.

Once we know the radius, we can find the area of the circle.

A = pi*r^2

A = pi(44/pi)^2

A = pi*(1936/(pi^2))

A = 1936/pi

A = 616.247939651819 approximately

I used my calculator's stored version of pi to compute the area in the final step.

We'll be comparing this number later, so hold onto it for now.

-------------------------------------

If Carter instead decides for a square, then 88 is the perimeter since it's the amount of fencing he has to work with.

Divide it into 4 pieces to find the length of each side of the square (all sides are equal in a square)

88/4 = 22

Each side is 22 feet

The area of this square is (22)^2 = 22*22 = 484 square feet

--------------------------------------

Summary:

  • If Carter goes for a circular enclosure, then he gets roughly 616.2479 square feet.
  • The square enclosure only gets him exactly 484 square feet.

The circle wins in terms of larger area.

The difference being roughly 616.2479  - 484 = 132.2479 square feet.
