17,18,18,19,21,22,46
Okay, I think you mean GCF, (Greatest Common Factor). :P Factors are the numbers multiplied by each other to get a number.
Example: Factors of 6: 1, 2, 3, 6. 1 times 6 = 6, and 2 times 3 = 6.
So, now you must find the GREATEST COMMON FACTOR IN VALUE between 40 and 50.
Factors of 40: 1, 2, 4, 5, 8, 10, 20, and 40.
Factors of 50: 1, 2, 5, 10, 25, and 50.
Which is the factor that BOTH 40 and 50 have?
Well, they have a lot of the same factors, but we need to find the GREATEST ONE in value. (By value, I mean the biggest number).
So it's clear that the factor 10 is the greatest common factor, soooooo.....
Final Answer: GCM = 10. :-)
Answer:
<em>4 seconds, 256 ft</em>
Step-by-step explanation:
First, we'll go through what needs to be done. Then we'll do it.
When h is 0, the fireworks is at a height of 0, or ground level. That happens before it is launched, at time 0 and when it falls back to the ground after going up and down. We let h = 0, and solve for t. We get t = 0, and another value for t which is when it hits the ground on the way down. The midpoint between the two times of height zero is the time at which maximum height is reached. Then we input the maximum height time into the equation and find h, the maximum height.
Now we'll solve it. First, we set the height equation equal to zero and solve for t.
-16t^2 + 128t = 0
-16t(t - 8) = 0
t = 0 or t - 8 = 0
t = 0 or t = 8
The height is zero at t = 0 seconds and at t = 8 seconds.
Maximum height is reached at the midpoint of the two times above.
(0 + 8)/2 = 8/2 = 4.
The firework explodes at 4 seconds.
Now we find the height at 4 seconds which is the maximum height.
h = -16t^2 + 128t
h = -16(4^2) + 128(4)
h = -256 + 512
h = 256
The firework explodes at a height of 256 ft.
