Answer:
468 sq. ft.
Step-by-step explanation:
A = 1/2 (a + b) (h)
= 1/2 (52) (18)
= 468 sq. ft.
Answer:
(-2,-36)
Step-by-step explanation:

<u>1) Find the zeros of the parabola</u>
The zero-product property states that any value, when multiplied by 0 will equal 0. Therefore, to make y=0, either (x-4)=0 OR (x+8)=0.
Therefore, x=4 and x=-8.
<u>2) Find the x-coordinate of the vertex</u>
To do this, we take the average of our zeros.

Therefore, the x-coordinate of the vertex is -2.
<u>3) Find the y-coordinate of the vertex</u>
Plug the x-coordinate back into the original equation

Therefore, the y-coordinate of the vertex is -36.
Therefore, the vertex of the parabola is (-2,-36).
I hope this helps!
Seeing as there are 1582 sets of 100 people (158200 ÷ 100) multiplying 42 by 1582 should get you the answer. 1582 × 42 = 66444. 66444 people voted in that city.
Answer: 29,113.2 km
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Circumference = 2 x π x radius
Replacing with the values given:
Earth's mean circumference = 2 π 6,371.0 = 40,030.2 km
Earth's moon mean circumference = 2 π 1,737,5= 10,917 km
Now, we have to subtract Earth's moon mean circumference to Earth's mean circumference:
40,030.2- 10,917 =29,113.2 km
