Answer:
An object is thrown straight up from the top of a building h feet tall with an initial velocity of v feet per second. The height of the object as a function of time can be modeled by the function h(t) = –16t2 + vt + h, where h(t) is the height of the object (in feet) t seconds after it is thrown.
Step-by-step explanation:
A ball is thrown straight up from the top of a 128 foot tall building with an initial speed of 32 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t2 + 32t + 128. How long will it take for the ball to hit the ground?
If 15% of the number was 9, i would divide it by fifteen and multiply by 100. Doviding by fifteen would get 1%, which in this case is 0.6. Then multiplying it by 100 would gove you 100%, or the whole number. The answer would be 60.
D. xb-a=y because it the close to being it it looks like
A vertex at the origin has the function f(x) = -x^2 because
x of vertex in this case so -b/2a = 0/(2*(-1) = 0 and so y = 0 so the vertex coordinates will be (0,0) what mean the origin
Answer:
For 11, x=18
Step-by-step explanation:
Use a ratio to solve for x since the triangles are similar
16/20=(16+12)/(20+x-3), first simplify both sides
4/5=28/(17+x), cross multiply
4(17+x)=5*28
17+x=5*7
x=35-16
x=18
