Answer 1

Answer: so pythagrorean theorem is the ideal way and easiest way to solve this

a^2+b^2=c^2

8.5^2+11^2=x^2
72.25+121=193.25
square root of 193.25=13.9014 or 13.9 in

9.5^2+15^2=x^2
90.25+225=315.25
square root of 315.25=17.7553 or 17.8 ft

The given functionrule is:

f(x) = 2x - 5. Therefore, the finished function table will end at 5.

How to finish the function table?

We must assess the function f(x) for each value of x given in order to finish the function table:

For x = -3:

f(-3) = 2(-3) - 5 = -6 - 5 = -11

For x = 0:

f(0) = 2(0) - 5 = -5

For x = 1:

f(1) = 2(1) - 5 = -3

For x = 4:

f(4) = 2(4) - 5 = 3

For x = 5:

f(5) = 2(5) - 5 = 5

The finished function table is as follows:

x f(x)

-3 -11

0 -5

1 -3

4 3

5 5

ending at variable 5.

The function rule that is provided is:

f(x) = 2x - 5
