Ineed serious someone explain this to me! the function p(t) = 145e-0.092t models a runner’s pulse, p(t), in beats per minute, t minutes after a race, where 0 ≤ t ≤15. graph the function using a graphing utility. trace along the graph and determine after how many minutes the runner’s pulse will be 70 beats per minute. round to the nearest tenth of a minute. verify

the runner’s pulse will be 70 beats per minute in 7.9 minutes

Step-by-step explanation:

Graph the function using a graphing utility.

Graph is attached below.

P(t) is beats per minute

Given P(t) is 70, so we plug in 70 for P(t) and solve for t

Divide both sides by 145

Now take ln on both sides

Divide both sides by -0.092

So t≈7.91564

Round to nearest tenth t= 7.9

We can verify it from second graph

1/4 because there is 4 grades.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
