Answer:
1/9
Step-by-step explanation:
when you have a negative exponent, you move the term to the denominator: 1/3^2
then you just do 3^2: 1/9
Answer: 1) 36 m and 60 m^2 2) 15π/2 + 10 m and 75π/4 m^2
Step-by-step explanation:
Using the pythagorean theorem in the first question, we get that the slope is 10 m so the perimeter = 10 + 14 + 6 + 6 = 36 m and the area is
(14 + 6)*6/2 = 60 m^2
So in the next question, the arc of the circle has a length of
2π*5*3/4 = 15π/2
So the perimeter is 15π/2 + 5 + 5 = 15π/2 + 10 m
And the area is 3/4*π*5*5=75π/4 m^2
Hope it helps
Hey there!
Exponents are basically multiplying the same number by itself. So, for example (2)(2)(2) is the same as 2³.
Just remember that 2³ is not the same as 2x3. 2³ means 2x2x2.
