Answer:
They are at the same height at 1.13 seconds.
Step-by-step explanation:
Remark
The rockets are at the same height when f(x) = g(x) [see below] are the same. So you can equate them.
Givens
f(x) = - 16x^2 + 74x + 9
g(x) = -16x^2 + 82x I have changed this so you don't have 2 f(x)s
Solution
- f(x) = g(x)
- -16x^2 + 74x + 9 = -16x^2 + 82x Add: 16x^2 to both sides
- -16x^2+16x^2+74x + 9 = -16x^2+16x^2 + 82x Combine terms
- 74x + 9 = 82x Subtract 74x from both sides
- 74x - 74x + 9 = 82x - 74x Combine
- 9 = 8x Divide by 8
- 9/8 = 8x/8
- x = 1 1/8 Convert to decimal
- x = 1.125
- x = 1.13 [rounded]

Answer:
The number -100 is a rational number and an integer
Answer:
x = 15
Step-by-step explanation:
by solving;
- 4x + 8x +14 -14 = 180
- 12x = 180
- x = 180 / 12
- x = 15

Answer:
Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds
Step-by-step explanation:
Given that a very large number of college men were asked what they thought their ideal weight was.
A five number summary of the response (in pounds) follows:
Median 175
Quartiles 155 196
Extremes 123 225
This implies that 25th percentile is 155 and 75th percentile is 196
This can be interpreted as approximately 50% of men lie between 155 and 196 pounds.
Since 195 is very near to 195, we can say approximately
i.e. 41 difference = 50%
40 difference =
Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds
