Answer:
5x - 1
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= 3x - 2 + 2x + 1 ← collect like terms
= 5x - 1
Well my man, if it does not give you a value for x.... your answer would be 2x
To find the approximate volume of the volcano, you will use the formula for finding the volume of a cone.
V = 1/3 x pi x r^2 x h
1/3 x 3.14 x 8^2 x 1.95
V = 130.624
The approximate volume of the volcano is 131 cubic kilometers.
Answer:
5 secs
Step-by-step explanation:
The height of the object is given as:

The moment when the object hits the ground, the height of the object will be 0 m.
Hence:

Solving this for t:
Divide through by 16 and move all parameters to the left hand side:


Since time cannot be negative, time, t = 5 secs.
The object will hit the ground after 5 secs.
I can run that mybe 40 times
