Answer:
396010000
Step-by-step explanation: You multiply 19,900 * 19900 because there are 2 pools and you will get your answer
Y = x^2 cos x
y' = x^2 * -sin x + cos x * 2x
= 2x cos x - x^2 sin x
= x ( 2 cos x - x sin x)
Answer:
the salesperson earned 5% which is; $26.5 then subtract 26.5 from the total made to find out how much the store made which is: $503.5
Step-by-step explanation:
<u>Given</u>:
Given that the graph OACE.
The coordinates of the vertices OACE are O(0,0), A(2m, 2n), C(2p, 2r) and E(2t, 0)
We need to determine the midpoint of EC.
<u>Midpoint of EC:</u>
The midpoint of EC can be determined using the formula,
Substituting the coordinates E(2t,0) and C(2p, 2r), we get;
Simplifying, we get;
Dividing, we get;
Thus, the midpoint of EC is (t + p, r)
Hence, Option A is the correct answer.
If you make the numbers into a ratio, it will be easier to find the answer.
There are 68 blue squares for the 4 green squares in the quilt.
68:4, or 68/4
If we do the division of the ratio, 68/4, we end up with 17.
Now, we multiply that by the 11 green squares of the new quilt.
17 x 11 = 187
