Answer:
Step-by-step explanation:
<u>Area of rectangle:</u>
<u>Given:</u>
<u>The area is:</u>
A = (2x - 7)(3x² + 4x) =
2x(3x² + 4x) - 7(3x² + 4x) =
6x³ + 8x² - 21x² - 28x =
6x³ - 13x² - 28x
The square roots for all of the answers would be rooted 2 squared time whatever number you picked for the first part
Answer:
0.78125 m
Step-by-step explanation:
First term of this geometric series is 50 m, and the common ratio is 1/2.
Thus, a(n) = (50 m)(1/2)^(n-1)
After the 7th bounce, the ball will reach a height of a(7) = (50 m)(1/2)^(7 - 1), or
a(7) = 50 / (2^6) m = 0.78125 m
