Answer:
Therefore it will take s for the object to reach the ground.
Step-by-step explanation:
Given function is
H(t) = -64 t²+169.
where H is height in feet, and t is time in second.
When the object touches the ground, the height of the object will be zero.
i.e H(t) = 0.
Therefore
H(t) = 0
⇒ -64 t²+169=0
⇒ -64 t²= -169
[ square root both sides]
Time can not be negative.
Therefore
Therefore it will take s for the object to reach the ground.
Answer: Neither
Step-by-step explanation: Neither, because both samples will supply the same information about their likely population.
Answer:
4
Step-by-step explanation:
plug 4 into x
parentheses first, 4x4 is 16, 16 - 10 is 6
6 times 1.25 is 7.5
Answer:
x = 4
Step-by-step explanation:
(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.
Knowing that, we can do the following:
- (5x+19) + (5x+131) = 180
- 5x + 19 + 5x + 131 = 180
- 10x + 140 = 180
- 10x = 40
- <em>x = 4</em>
The answer is 73.
