Match each exponential function to the description of its percent rate of change. 22% growth 12% decay 2% decay 20% growth 20% d
makvit [3.9K]

The exponential function is defined as y = a(1+r)^x, where "a" represents the original account and "r" the rate of growth or decay.

Then we have the following:

1) 22% grow

y = a( 1 + 22%/100 )^x = a(1.22)^x

So the solution is: 124(1.22)^x

2) 12% decay

y = a( 1 - 12%/100 )^x = a(0.88)^x

So the solution is: y = f(x) = 44(0.88)^x

3) 20% decay

y = a( 1 - 20%/100 )^x = a(0.8)^x

So the solution is: f(x) = 22(0.8)

4) 12% Groth

y = a( 1 + 12%/100 )^x = a(1.12)^x

So the solution is: f(x) = 42(1.12)^x

A salt water solution is cooled to -3C. During an experiment , the mixture is heated so that its, temperature rises at steady ra
JulijaS [17]

Answer:

y = -3+ rx

Step-by-step explanation:

Given

Base = -3C

Time = x

Required

Determine the equation (y)

Let the steady rate be represented with r.

So, the equation (y) can be determined using:

y = Base + Rate * Time

y = -3+ r* x

y = -3+ rx
