Answer:
Step-by-step explanation:
m = 1/2, (18,10)
y - y = m(x-x)
y - 10 = 1/2 (x - 18)
y - 10 = 1/2x -9
y = 1/2x - 9 + 10
y = 1/2x + 1
<h3>Initial amount = 1</h3><h3>Rate of growth = 80 %</h3><h3>The value is 18.9 when t = 5</h3>
<em><u>Solution:</u></em>
<em><u>The given exponential function is:</u></em>

<em><u>The exponential function is given as:</u></em>

Where,
y is the future value
a is the initial value
r is the growth rate
t is the number of years
<em><u>Compare both the functions,</u></em>
a = 1

Thus growth rate is:
<em><u></u></em>
<em><u>Evaluate the function when t = 5</u></em>
Substitute t = 5 in given

Thus the value is 18.9 when t = 5
+ <span>use t for the number of hours the meeting room is rented
+ </span><span>college charges a reservation fee of $49 and an additional fee of $5.40 per hour.So we have 49+ 5.40t
+ </span>the film club wants to spend less than $81.40 on renting the meeting room, and we need:<span>49+ 5.40t< 81.40
or 5.40t < 81.40- 49
and 5.40t< 32.40
t< 32.40: 5.40= 5.629
So </span><span>the possible amounts of time for which they could rent the meeting room 5.6 hours</span>
If we call the unknown number x, we have:
- 7 times a certain number is

- If we subtract 8, we have

If this equals 34, we have

Add 8 to both sides:

Divide both sides by 7:
