Answer:

9.6 ft

Step-by-step explanation:

The cone is shown in the attachment

The volume of a cone is calculated using: V=\frac{\pi r^2h}{3}

We have that the volume is 83.7 and from the diagram , the height is 3.5 ft.

We substitute to obtain:

83.7=\frac{3.14*r^2*3.5}{3}

This implies that:

r^2=\frac{83.7*3}{3.5*3.14} \\r^2=22.848\\r=\sqrt{22.848}\\ r=4.8

The diameter is two times the radius.

Therefore the diameter is 2(4.8)=9.6ft

Simplify: (-3x^3+2x^2+4x)-(8x^4-5x^3+6x^2-2x
sergejj [24]

Answer:

−8^4+2^3−4^2+6

Step-by-step explanation:

Distribute the - to 8x^4-5x^3+6x^2-2x:

-8x^4+5x^3-6x^2+2x

Now simplify:

-3x^3+2x^2+4x-8x^4+5x^3-6x^2+2x= −8^4+2^3−4^2+6

PLS HELP! WILL GIVE BRAINLIST!
Vlad [161]

Answer:

y = 3x

Step-by-step explanation:

y = 13

x= 4

here

y∝x

that is

y= k x where k is constant

Since the equation is in the formy=kx we know that

13=K×4

k=13/4=3.25

so we can write this

y = 3.23 x ≅ 3x

Simplify the following expression.
love history [14]

Answer:

20

Step-by-step explanation:

Remember PEMDAS!

So first parentheses:

1.6^2 = 2.56

8.7 + 9.3 = 18.

Because that is inside another parentheses you multipy them.

2.56 x 18 = 46.08

Now: 46.08 divided by 1.8 = 25.6

Now subtract:

25.6 - 3.7 - 1.9 which equals 20!

Hope that helped!

If f(x) = 2x^2+3 and g(x)= 5x, evaluate the following: a. f(g(x)) b. g(g(3)) c. g(f(-2))
marissa [1.9K]

Answer:

A = 50x^2+3

B = 75

C = 55

Step-by-step explanation:

f(x)=2x^2+3\\g(x)=5x

A. f(g(x))

2(5x)^2+3\\2(25x^2)+3\\=50x^2+3

B. g(g(3))

5(5(3))\\5(15)\\=75

C. g(f(-2))

g(2(-2)^2+3)\\g(8+3)\\g(11)\\5(11)\\=55
