Answer:
It's either 39.2 or 39.3 (a more accurate answer) because it depends on what you round by. since it's Delta Math, you should get 2 attempts.
Step-by-step explanation:
Since they are similar, they are proportional.
54/11=4.90909091 or 4.9
Multiply 11 by 4.90909091 and you get 54
Multiply 8 by 4.90909091 and you get 39.3
if you multiply by 4.9 you get 39.2
The recursive function is f(n + 1) = 2f(n) where f(1) = 4
<h3>How to determine the recursive function?</h3>
From the graph, we have the following values
f(1) = 4
f(2) = 8
f(3) = 12
Divide f(2) by f(1) to calculate the rate (r)
r = f(2)/f(1)
r = 8/4
r= 2
Substitute r= 2 in r = f(2)/f(1)
f(2)/f(1) = 2
Make f(2) the subject
f(2) = 2f(1)
Express 2 as 1 + 1
f(1 + 1) = 2f(1)
Express 1 as n
f(n + 1) = 2f(n)
Hence, the recursive function is f(n + 1) = 2f(n) where f(1) = 4

She'll need 7 patches- 28/4 = 7
Hope this helps :)
-3/4x + 5/6 y = 15
Multiply through by 6
-9/2x + 5y = 90
Add 9/2x to both sides
5y = 90 + 9/2x
Divide both sides by 5
y = 18 + 9/10x
y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c
Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
Let us assume the width of the rectangle = x meters
Then
Length of the rectangle = 2x + 2
Perimeter of the rectangle = 16 meters
Then
Perimeter = 2 (Length + width)
16 = 2(2x + 2 + x)
16 = 2(3x + 2)
16 = 6x + 4
6x = 16 - 4
6x = 12
x = 2
Then
Length of the side of the rectangle = 2x + 2
= (2 * 2) + 2
= 6
I hope that the procedure is clear enough for you to understand and this is the answer that you were looking for.
