8. The graph below shows the amount of money that a student has in the bank at the end of each week.
1 answer:
The student will have 130 dollars in the bank at the end of week 11.
The missing graph is attached with the answer.
<h3>What is a Linear Function ?</h3>A linear function is a function that can be represented by the formula y = mx+c ,
m is the slope of the equation , c is the intercept at y axis.
The student will have 130 dollars in the bank at the end of week 11.
For each passing week, the student will have $10 more in the bank than at the end of the previous week. So, following this pattern:
At 4 week $50
At 5 week $60
The slope =
m =( 60-50)/1 = 10
y = 10x +c
at x = 0 , y = 20
c = 20
The equation is
y = 10x +20
y = 110 +20
y = $130
At the end of 11 weeks, he will have $130.
The student will have 130 dollars in the bank at the end of week 11.

Answer:
x = 3.76 ft
Step-by-step explanation:
To find the missing side, "x", solve using proportions.
In similar polygons, the 'new' polygon was created by multiplying every side of the 'old' polygon by the same number. Every side was multiply by the <u>scale factor</u>, "k", which tells you how much a polygon grew (k>1) or shrunk (0<k<1).
Therefore, if you divided the pairs of corresponding sides, they would be equal.
From the diagram, you can tell that the following sides correspond:
CB ~ GF
AB ~ EF
<u>Use the proportion</u>
Substitute values from diagram
Multiply both sides by 6 ft
"x" is isolated. Multiply fraction by combining into numerator
Solved numerator. Divide for decimal answer.
The value of 'x' is 3.76 ft.
