It would be C.

For example, say 1 person comes. This would be x=1. Plugging this in gives you,

y=0.5 + 1.3

This shows that C is true since x is always going to be multiplied by 0.5.

1.3 would be the base amount of time it takes to arrange since if it the y-intercept.

If an object is projected upward into the air from ground level, then the height h(t) of the object
AfilCa [17]

Answer:

21.5secs

Step-by-step explanation:

Given the function that models the height of an object as

h(t) = -16t^2+ 344t

The object hit the ground at h(t) = 0

Substitute

0 =  -16t^2+ 344t

16t^2 = 344t

16t = 344

t = 344/16

t =  21.5

Hence it takes 21.5secs for the object to hit the ground

Steps for graphing -x^2-4x-3
sdas [7]

Answer:

:)

Step-by-step explanation:

There are several ways to do this. The first, which I personally think is the quickest way without having to do too much math or rearranging the equation is to simply pick random points for x and solve for y.

For instance, you might try -2 for x.

- ( - 2)^2 - 4 ( - 2) - 3

= - 4 + 8 - 3

= 1

So one of your points would be (-2, 1)

Then you might choose, say, -3 for x. And after that, -1 for x. If you want to graph even more points after those (the more points, the more accurate your graph), choose -4 and 0 for x. Simply put it into the equation and find y. Then graph.
