The projectile motion of an object is modeled by the function h (t) = -16t2 + vt + c, where v is the initial velocity of the object, c is the initial height of the object, t represents the time the object is in motion.

the function model can be used to predict the height of an object in motion over time. if the initial velocity of an object is 59 feet per second and the initial height is 6 feet, which function represents the height of the object after t seconds?

The function represents the height of the object after t seconds is

Step-by-step explanation:

The projectile motion of an object is modeled by the function

where, v is the initial velocity of the object,

c is the initial height of the object,

t represents the time the object is in motion.

Given that v=59 ft/s and intial height is h(0)=6 ft

h(0)=6 ft

h(0)=

h(0)=c

So, c= 6

Therefore, The function represents the height of the object after t seconds is

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

i did it myself and i got 4.2 (b) hope its right
