Aparatrooper jumps from a plane at an altitude of 4500 ft and descends at the rate of 20 ft/sec. what is the formula for the paratrooper’s height, h, above the ground after t seconds?

a: h=4500/20t
b: h=20t+4500
c: h=4500+20t
d: h=4500/20*t

The correct answer is option B

Step-by-step explanation:

Let the change in height after "t" seconds be "h"

Thus, the mathematical equation can be written as

Thus, the correct answer is option B

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
