How are mountains and plateaus alike?

IgorLugansk [536]

Answer:

It is similar to a mountain in that it is dramatically higher than what is immediately around it. But mountains usually have a distinct apex or peak that is very small relative to the base and not typically level. Plateaus and mesas have tops only a little smaller than the base, and relatively flat. If the aspect ratio is less than 1, plateau. If greater than 1, mesa.

April shoots an arrow upward into the air at a speed of 64 feet per second from a platform that is 11 feet high. The height of t

kogti [31]

Answer:

Maximum height of the arrow is 203 feets

Step-by-step explanation:

It is given that,

The height of the arrow as a function of time t is given by :

$h(t)=-16t^2+64t+11$ ..........(1)

t is in seconds

We need to find the maximum height of the arrow. For maximum height differentiating equation (1) wrt t as :

$\dfrac{dh(t)}{dt}=0$

$\dfrac{d(-16t^2+64t+11)}{dt}=0$

$-32t+64=0$

t = 2 seconds

Put the value of t in equation (1) as :

$h(t)=-16(2)^2+64(2)+11$

h(t) = 203 feet

So, the maximum height reached by the arrow is 203 feet. Hence, this is the required solution.
