let CD=h and BC=x
h/x = tan24
h/(x+7600) = tan16
h = 0.4452x
h = 0.2867x + 2179.2649
0.4452x = 0.2867x + 2179.2649
BC = 13750 feet
CD = 6121 feet
<span>Step 1. Intercepts occur when one of the coordinates is equal to 0. So the y-intercept occurs at x=0 and the x-intercept occurs at y=0.
Step 2. It takes two points to make a line. So use these intercepts points
Step 3. When x=0, then 0-y=3 or y=-3. So we have point (0,-3).
Step 4. When y=0, then x-0=3 or x=3. So we have another point (3,0).
Step 5. Graph the line as shown below using these two points found in Steps 3 and 4.
Note x-y=3 can be written as y=x-3 in slope-intercept form where slope m=1 and y-intercept b=-3.</span>
The zeros are the values of t for which f(t) = 0.
i.e. <span>-16t^2 + 96t = 0
16</span>t^2 - 96t = 16t(t - 6)
16t = 0 or t - 6 = 0
t = 0 or t = 6
Therefore, the zeros are 0, 6
The time taken for the ball to hit the ground is the value of t when f(t) = 0.
i.e. t = 6.
It equals to 9/5 * (4/3) = 12/5
174 is equal to 174 if thats what the last one means
