Step-by-step explanation:
The object will hit the ground after 5 seconds. You can rewrite the quadratic function as a quadratic equation set equal to zero to find the zeros of the function 0 = -16t2 + 80t + 0. You can factor or use the quadratic formula to get t = 0 and t = 5. Therefore, it is on the ground at t = 0 (time of launch) and then hits the ground at t = 5 seconds.

Answer:
y = .25x + 50
Step-by-step explanation:
Let's use the slope-intercept equation for this problem:
y = mx + b
where m is the slope and b is the y-intercept
In this problem, m is the amount Chris pays per text and b is the flat rate.
m = price per text = .25
b = flat monthly fee = 50
Let's plug these values into the equation:
y = mx + b
y = .25x + 50
where y is the total cost for a month and x is the number of text messages
Therefore, the function is y = .25x + 50
