Lisa is standing on a dock beside a lake. She drops a rock from her hand into the lake. After the rock hits
the surface of the lake, the rock's distance from the lake's surface changes at a rate of -6 inches per
second. If Lisa holds her hand 5 feet above the lake's surface, how far from Lisa's hand is the rock 6
seconds after it hits the surface?
The rock is
inches away from Lisa's hand.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
