Modeling Exponential Growth and Decay In Exercises 119 and 120, Find the exponential function
Lubov Fominskaja [6]

Answer:

There is no exponential function passing through (1,1) and (5,5).

Step-by-step explanation:

We have the following exponential function

y = Ce^{kt}

The function passes through these two points:

(1,1): This means that when t = 1, y = 1

(5,5): This means that when t = 5, y = 5.

So

(1,1)

y = Ce^{kt}

Ce^{k} = 1

e^{k} = \frac{1}{C}

(5,5)

y = Ce^{kt}

5Ce^{k} = 1

Ce^{k} = \frac{1}{5}

From above, we have that:

e^{k} = \frac{1}{C}

C\frac{1}{C} = \frac{1}{5}

1 = \frac{1}{5}

1 cannot be equal to 1/5, so this is wrong.

This means that there is no exponential function passing through (1,1) and (5,5).

Driving 70 mph, it takes Alicia 2 hours to reach the airport to go on a vacation. It then takes her 2 hours to get to her destin
OLga [1]

She drove 2 hours at 70 miles per hour, so she drove 70 * 2 = 140 miles total.

The jet traveled 400 miles per hour for 2 hours for a total of 400 * 2 = 800 miles.

Total miles = 140 + 800 = 940 miles.

The answer is C.
