Answer:
It should be t = 1.5 seconds if your equation is h(t) = -16*t^2 + 8t + 24
Step-by-step explanation:
h(t) = -16*t^2 + 8t + 24
We want to solve for t when h(t) = 0.
This is a parabolic equation so basically we can use the quadratic formula to solve this.
h(t) = -16*t^2 + 8t + 24
0 = h(t) = -16*t^2 + 8t + 24
take out the 8
0 = -2t^2 + t + 3
0 = -2t*t - 2t + 3t + 3
0 = -2t * (t + 1) + 3*( t + 1)
0 = (-2t + 3) * ( t + 1)
so time cannot be negative, so we choose 0 = (-2t + 3), t = 3/2 seconds
or t = 1.5 seconds

Answer:
m = 1
, y = 1x + 10
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. I will be calculating the slope using the points (7, 2) and (0, 10)
m = 
= 
= 
= 1
Based on the graph, the y-intercept is 10. Thus, the equation of the line is 1x + 10.

Answer:
$10.88 or round up to $11
Step-by-step explanation:
Since 15 is expressed as a percent, you can convert it to a decimal.
.15, which can also be 15/100 if you were to write it as a fraction.
You are trying to find 15% of 72.50 so you would need to multiply your new decimal (.15) to your meal total. This will give you 10.875 or 10.88.
