Answer:

The value of the expression when i is 1 is equals to 5.

Step-by-step explanation:

We are given the following expression:

2 + 3^{i}

Evaluate the expression when i is 1.

We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So

2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5

The value of the expression when i is 1 is equals to 5.

henry rented a truck for one day. there was a base Fee of $18.95, and there was an additional charge of $.79 for each mile drive
crimeas [40]
<h3>Henry drove the truck for 208 miles</h3>

<em><u>Solution:</u></em>

Given that,

Base fee = $ 18.95

Additional charge of $.79 for each mile driven

Let "x" be the miles driven

Henry had to pay $183.27 when he returned the truck

Therefore,

Cost for rent = base fee + charge for "x" miles

183.27 = 18.95 + 0.79x

0.79x = 183.27 - 18.95

0.79x = 164.32

Divide both sides by 0.79

x = 208

Thus Henry drove for 208 miles the truck
