Reason and Apply
6. APPLICATION A car is moving at a velocity of 68 mi/h from Dallas toward San
Antonio. Dallas is about 272
mi from San Antonio.
In your notebook:
a. Make a table of values relating time to distance from San Antonio for 0 hours to 5 hours in 1-hour
intervals.
b. Write a recursive rule for your table. (include both parts and the phrase "to get from one term to the

In Desmos:
c. Plot your table and choose appropriate scale on the x and y axes to show the data.

ab will be equal to

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
