nice

Step-by-step explanation:

jody

The function should be 2.5h + 4 = 12

Full Question:

Jody has already hiked 4 kilometers. The trail is 12 kilometers long. She can hike 2.5 per hour. Which function will help Jody figure out how many more hours, h, she needs to hike?

Step-by-step explanation:

Let number of hours = h  

Given that she can hike 2.5 per hour. So that means distance travelled in "h" hours will be 2.5h  

It is also given that Jody has already hiked 4 kilometers.  

So total distance travelled by Jody in "h" hours will be (2.5h + 4)  

Given that trail is 12 kilometers long.  

That means Jody has to travel for 12 kilometers. In that case both values will be equal and we get equation:  

2.5h + 4 = 12

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
