Answer:

1. 923.16 or 294 Pi

2. 3052.08 or 972 Pi

Step-by-step explanation:

Formula for volume of a cone = Pi r^2 h/3

If diameter is 14, radius is 7

Pi 7^2 18/3

Pi 49 6

Pi 294

923.16

Formula for volume of a sphere = 4/3 pi r^3

If diameter is 18, radius is 9

4/3 pi 9^3

4/3 pi 729

972 pi

3052.08

a meteorologist measures the angle of elevation of a weather balloon with the ground as 41. A radio signal from the balloon indi
Aneli [31]
Here you would use right triangle trig (SOH CAH TOA)
So first draw a right triangle. Imagine youre standing at the angle opposite the right angle which is the one on the ground.This angle is the 41°. Now Imagine the balloon is as the angle above the right triangle. Well since the balloon is 1503 m from his location this would be the hypotenuse. SInce we are trying to find the height (x) we would use sine since
sine = opposite/hypotenuse . Now lets solve make sure calculator is in degree mode:

sin41 = x/1503      multiply both sides by 1503 to cancel it out
1503sin41 = x        plug into calculator
x = 986.057 ft
The balloon is 986.057 feet above the ground.

Find f(-5) f(x) -4x + 3
Fiesta28 [93]

Answer:

if f(x)= -4x+3

f(-5)= 23

Step-by-step explanation:

first you substitute x for -5

f(-5)= -4(-5)+3

then you multiply

-4(-5)

f(-5)=20+3

you get the positive 20 because negative times negative equals positive

then you just add the rest (20+3) which will give you your answer

f(-5)= 23

48c + 12 = 12(_______)
inn [45]

Answer:

\large\boxed{12(4c+1)}

Step-by-step explanation:

How to factor expressions?

Find the G.C.F. and divide it into the terms of the expression you need to factor, like this:

48c+12=12(4c+1)}. So I took the 12 and pulled it out of both terms, obtaining 12(4c+1).

-4(-3x - 8) - 4x + 8 = -8x + 40
Andrew [12]
First we expand and combine the terms on the left side.  This gives us

12x + 32 -4x + 8 = -8x + 40 

8x + 40 = -8x + 40.  Because the two sides cancel each other out when you try and bring all the x to one side, the answer is x = 0.
