Answer:
(1/2, 6).
Step-by-step explanation:
Turning points in a graph may exist whenever the derivative equals 0. Hence, let’s differentiate and then solve our function.
We have:

Take the derivative of both sides with respect to x:

Simplify:

We will now set this equal to 0 and solve for x. Hence:

Hence, the graph turns at x=1/2. This is the x-coordinate.
Then it follows that the y-coordinate will be:

Hence, our coordinate Is (1/2, 6).
Answer:
π/3.
Step-by-step explanation:
Area of circle = πr^2 = 25π (r = 5)<span>
72 degrees is 1/5 of circle
so 25</span>π / 5 = 5π
<span>
area of triangle = 1/2 bh
</span>area of triangle <span>= 1/2(5.8)(4)
</span>area of triangle <span>= 11.6
area of figure = 5</span>π - 11.6
<span>
answer
A. (</span>5π - 11.6 ) ft^2<span>
</span>
Answer:
G.
Step-by-step explanation:
cards = 2
dollars = 9
to check that the number of cards with the correct amount d;
use the ratio and proportion.
(3 x 18)/9 = 4
(4 x 31.5)/18 = 7
(7 x 45)/31.5 = 10
therefore, option G. table G. is the correct answer
try doing the ratio and proportion on the other table and the number of cards DO NOT match with the amount. (see attached)
