For this case we have the following equation:
h (t) = at ^ 2 + v * t + h0
Substituting values we have:
h (t) = - 16 * t ^ 2 + 60 * t + 3
We equate the equation to zero:
-16 * t ^ 2 + 60 * t + 3 = 0
We look for the roots of the polynomial:
t1 = -0.04935053979258153
t2 = 3.7993505397925817
We are left with the positive root and round:
t2 = 3.8 s
Answer:
t = 3.8 s
option 3
The answer is 214,23 dollars. (1,02^3 * 3500)-3500 = 214,23
Y = 2x + 3
First, find the y-intercept (b). This is where the line meets the y-axis. The line meets the y-axis at 3, so the y-intercept is 3.
Now, find the slope (m) of the line. Slope is rise divided by run. The line goes up by 2, over by 1, up by 2, over by 1, and so on. So, the rise is 2 and the run is 1. 2 divided by 1 is 2, so the slope is 2.
Put these together into the equation to get y = 2x + 3.
Answer:
y=e -1
