the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
Answer:
64.8
Step-by-step explanation:
Pythagoreon Theroem
a^2 + b^2 = c^2 in this situation it would actually be the opposite, seeing where the "x" is (on a leg) c^2 - b^2 = a^2. First take the square of 67 and 17
67 squared is 4489 and 17 squared is 289 then subtract both results
4489-289 = 4200 take the square root of this number
64.8074 (Round to the tenths 64.8)
As a mixed number it’s 7 6/9 -not too sure about improper fraction. just know that repeating decimals always have a 9 as the denominator -hope that helps :)
