A pizza is removed from the oven at a temperature of 425 F. After 15 minutes, the pizza has cooled to 200°F. Use a continuous exponential decay model to find the approximate decay

rate.

WILL MARK BRAINLIEST!! 20 POINTS!

The decay rate is of 0.05 = 5% per minute.

Step-by-step explanation:

Continuous exponential decay model:

The exponential equation of decay for an amount, after t units of time, is given by:

In which A(0) is the initial amount, e(approx 2.72) is the Euler value and r is the decay rate, as a decimal.

A pizza is removed from the oven at a temperature of 425 F.

This means that

After 15 minutes, the pizza has cooled to 200°F.

This means that , that is, when

We use this to find r.

The decay rate is of 0.05 = 5% per minute.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20
