Actually the position function with respect to time under constant acceleration is:
a=g
v=⌠g dt
v=gt+vi
s=⌠v
s=gt^2/2+vit+si
So if vi and si are zero then you just have:
s=gt^2/2
Notice that it is not gt^2 but (g/2) t^2
So the first term in any quadratic is half of the acceleration times time squared because of how the integration works out...
Anyway....
sf=(a/2)t^2+vit+si
(sf-si)-vit=a(t^2)/2
2(sf-si)-2vit=at^2
a=(2(sf-si)-2vit)/t^2 and if si and vi equal zero
a=(2s)/t^2
The answer is isosceles trapezoid.
If the function is:
y=a cos( bx+c), or y=a sin(x+c)
then the period is T= 2π/b and if T=2:
2=2π/b
b=2π/2=π
Answer: B) y=3 cos πx
Answer:
The answer is 8.96278<u>7</u> .
Step-by-step explanation:
The number above is :
8 = Ones place
8.9 = Tenth place
8.96 = Hundredth place
8.962 = Thousandth place
8.9627 = Ten thousandth place
8.96278 = Hundred thousandth place
8.962786 = Millionth place
8.96278<u>7</u> = Nearest millionth
Answer:
425%
Step-by-step explanation:
4 can be written as 4.00 in decimal form. 1/4 can be written as 0.25 in decimal form. When changing a decimal into a percent, you move the decimal to the right two times. If we move the decimal point in 4.00 twice we get 400. If we move the decimal point in 0.25 twice we get 25. If we add 400 and 25 together, we get 425. Therefore, the answer is 425%. Hope this helped! :)
