Answer: the one that ends with 30. D the fourth one
Step-by-step explanation:
Answer:
Step-by-step explanation:
We are looking for what number times .50 makes the equation true.
So, just do backwards equation:
Thus, meaning that what multiplied by 0.50 is equal to 17?
[tex]0.50 * 34[tex]
[tex]==> 17[tex]
80 square units

The Formula for the area of a trapezoid is A= (a+b/2)h
A= 3+17/2 (8)
A= 20/2 (8)
A= 10 (8)
A = 80
Answer:
The answer is (d) ⇒ e = 1/7 , k = 12 , conic ellipse
Step-by-step explanation:
∵ r = ek/(1 ± ecosФ)
∵ r = 12/(7 - cosФ) ⇒ ÷ 7 up and down
∴ r = 12/7 ÷ 1 - 1/7 (cosФ)
∴ e = 1/7
∵ 12/7 = ke ⇒ 12/7 = k(1/7)
∴ k = 12
∵ 0 < e < 1
∴ The conic is ellipse
