F(0)=4-8x
f(0)=4-8(0)
f(0)=4
Answer: 92
Step-by-step explanation:
Formula : Sum of first n numbers = Average x n
Given: Average score on first 6 tests= 84
A score on all 8 tests = 86
Then, Sum of first 6 numbers = 84 x 6 = 504
Sum of first 8 numbers = 86 x 8 = 688
Sum of two last numbers = (Sum of first 8 numbers) - (Sum of first 6 numbers)
= 688-504
=184
Average of last two numbers = (Sum of two last numbers )÷2
= 184÷2
= 92
Hence, the average of your last two test scores = 92.
Since R is the midpoint of OS, OR = RS, because the definition of the midpoint is a point that is equidistant to the other two points.
PR = PQ + OR
PR = PQ + RS because of the reasoning above.
Using the Pythagorean Theorem we can solve this:
20^2 + 6^2 = X^2
400 + 36 = x^2
436 = x^2
x = SQRT(436)
x = 20.9 feet long
