Pleas help I will do anything in return As part of a publicity stunt (an event designed to draw attention), a TV host drops a watermelon from the top of a tall building. The height of the watermelon x
seconds after it is dropped is given by the function h(x) = (25+4x)(25 - 4x),
where h(x) is measured in feet.
1:Rewrite h(x) in standard form
2:when does the watermelon hit the ground?
3:is the watermelon still in the air after 8 seconds after it drops?
4:what is the height of the watermelon after 3 seconds?

answer: d. $20

step-by-step explanation:

just took the test

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

answer: i don't understand it

step-by-step explanation: sorry
