Answer:

a) 6.5 seconds
b) 13 seconds
c) 679 ft

Step-by-step explanation:

Given function:

h(t) = -16t^2 + 208t + 3

a) Maximum height is the vertex. The ball reaches the maximum after:

h = -208/2(-16) = 6.5 seconds

b) Time the ball was in the air:

-16t^2 + 208t + 3 = 0

Solving we get approximately t = 13 seconds

c) Maximum height is at vertex, we found t above:

h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft

Asha found that a vertical line intersects the graph of x = StartAbsoluteValue y EndAbsoluteValue at two points. What can Asha c

Gnoma [55]

Answer:

what can i help u with

Step-by-step explanation:

The graph of x = |y| is as shown in the figure.

When we draw a vertical line, it intersects the graph at two points.

This means for the same value of x , we have two values of y.

Or in other words, for the same pre image, we have two images.

Hence it is not a function.

But for every value of x, we do have a value of y, hence it is a relation.

x = |y| is a relation but it is not a function

Help me please. what is the solution for 4≤n−4

notka56 [123]

Answer:

n $\geq$ 8

Step-by-step explanation:

You add 4 to both sides to make n the only thing on one side. Then to make the answer look better you move n to the left side and flip the symbol because n changed sides.

$4\leq n-4\\ 4+4\leq n-4+4\\ 8\leq n\\ n\geq 8$

hammer [34]

The angle A=180-37=143 degrees

and the angle B is equal to the angle A because l and m are parallel line then B=143 degrees

angles C and D are equal to A and B too, then C=D=143 degrees

angles G, E and F are equal to the given angle because they are opposite by the vertex and alternal internal, then G=E=F=37 degrees
