Answer:
-8
Step-by-step explanation:
Multiplying two negatives (or squaring them) cancels the negative, therefore, (-8)^2=64
Opposites:
a. -3
b. 9
c. 5
d. -12
250 adults and 180 of which are parents, so 250 -180 = 70
are not parents.
<span>The results showed that 150 of the adults with children and
40 of those without thought the park should be expanded. So there are 180 – 150 = 30 parents who
answered no. and 70 – 40 = 30 not parents who answered no.</span>
<span>
yes | no
parents 150 | 30
not parents 40 | 30

Answer:
(A) 2/3 [√(4-4x)]^3
(B) 2/3 [√(4-x)]^3
Step-by-step explanation:
Integrating the functions,
(A) Any function in square root is equal to or same as the function raised to the power of 1/2
To integrate, add 1 to the power of the function. That's 1/2 + 1 = 3/2
Divide the function by this new power 3/2. This implies multiplying the function by the inverse of 3/2. The inverse of 3/2 is 2/3.
Also, when a function is raised to the power of a fraction instead of a whole number, you take the 'denominator' root of the function, and then raise the function to the power of the numerator.
Here, the denominator is 2, so you take the square root of the function, and raise the function to the power of 3
So the integral of Y = √[4-4x] is
2/3 [√(4-4x)]^3
(B) In like manner, the integral of
Y = √[4-x] is
2/3 [(√4-x)]^3
