Just a quick question: I'm doing a math problem regarding exponential decay, where the number of acres in a rainforest starts at 800 square miles, and decreases by 20%. Because it's decreasing, would that mean that the equation would be ?

You need to subtract the rate of decay from 1.

The equation would be 800(1-0.2)^x = 800(0.80)^x

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%
