4 0

Answer:

32 and 39

Step-by-step explanation:

The common difference d for the sequence is 7

1st term of the sequence a1 is 11.

4th (a4) and 5th (a5) term of the sequence are required

nth term of an arithmetic sequence an =a1+(n-1)d

a4=11+(4-1)7=32

A stone is dropped from the edge of a roof, and hits the ground with a velocity of -185 feet per second. How high (in feet) is t

34kurt

Answer:

The height of the roof is 534.8 feet.

Step-by-step explanation:

Let h be the height of the roof.

We know the formula

$v^2-u^2=2gh$

Since, the stone is dropped from the edge of the roof hence, the initial velocity should be zero. Thus, u = 0

$v^2-0=2gh\\h=\frac{v^2}{2g}$

Now, we have

v = -185 feet per second

g = 32 feet per square second

On substituting these values, we get

$h=\frac{(-185)^2}{2\times 32}\\\\h=534.8$

The height of the roof is 534.8 feet.
