Barbara sets off a water-powered rocket. The height of the rocket at time t seconds is given by h(t) = - 1612 + 96t.
Use the quadratic formula to estimate when into the trip the
rocket is 64 feet high.
A
at about 1.2 seconds and about 4.8 seconds
B
at about 0.8 second and about 5.2 seconds
C
at about 2.2 seconds and about 3.8 seconds
D
at about 0.6 second and about 5.4 seconds

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

a)(x-2)^2+(y-1)^2=9

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
