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
Answer:
$94.50
Step-by-step explanation:
2 times 9 is 18 leaves a remainder of 1
then that leaves 15 an 2 times 7 gives you 14
so that will be $94.50 for a single meal
Answer:
- c(m) = 39.95 +0.35m
- 85 minutes over 500
Step-by-step explanation:
Let m represent the number of minutes used over 500. Then the cost of the cell phone plan is ...
c(m) = 39.95 +0.35m
__
For a cost of 69.70, the number of excess minutes can be found by solving ...
69.70 = 39.95 +0.35m
29.75 = 0.35m . . . . . . . . . subtract 39.95
29.75/0.35 = m = 85 . . . . divide by the coefficient of m
The number of minutes of usage over 500 is 85.
The answer is <span>A –x^2 + 3x + 15
</span>
3x² + 6 – 2x + 5x – 4x²<span> + 9
Rearrange it:
</span>3x² + 6 – 2x + 5x – 4x² + 9
= 3x² - 4x² - 2x + 5x + 6 + 9
= -x² + 3x + 15
