Answer:
you could divide
Step-by-step explanation:
32 if you fold it 4 times and times that by 2 it will be 32
<u>Given</u>:
Four lines are marked proportion, the length of TW can be determined by

<u>Value of a:</u>
Let us set the proportion for the given lines.
Thus, we have;



Thus, the value of a is 5.6
<u>Value of b:</u>
Let us set the proportion for the given lines.
Thus, we have;



Thus, the value of b is 5.
<u>Length of TW:</u>
The length of TW is given by


Thus, the length of TW is 13.6
-165...you take -5.5 times 30 and you get -165
Let y=f(x)
y=sqrt(10-3x)
you want to make x the subject
square both sides
y²=10-3x
3x=10-y²
x=(10-y²)/3
now replace y with x
f^-1(x)=(10-x²)/3
