Answer:
The time it takes for the cannonball to hit the ground is 6.49 seconds.
Step-by-step explanation:
You know that the height of the cannonball above the ground, h, in meters, in time, t, in seconds, is found by the function h(t) = -4.9t² + 30.5t + 8.4. You want to calculate the time it takes for the cannonball to hit the ground, that is, the time it takes for the bullet to reach zero height. So, being h(t) = 0 you have:
0 = -4.9t² + 30.5t + 8.4
To solve a quadratic function 0=a*x² + b*x +c, the expression is applied:
In this case, being a = -4.9, b =30.5 and c =8.4 you have:
Solving you get:
t1= -0.26 seconds and t2=6.49 seconds
Since time does not have a negative value, then <u><em>the time it takes for the cannonball to hit the ground is 6.49 seconds.</em></u>
Answer:
SU=5 the first option.

I did the assignment.
Hey there,
Your question/statement states: <span>Angle </span>
<span> is the complement of angle </span>
<span>, and angle </span>
<span> is the supplement of angle </span>
<span>. what is the difference between the measures of angle </span>
<span> and angle </span>
There is not difference between angle
and
The reason why would be because they both are congruent to angel
. If they are both congruent to that angel, then they are both the same shape. One thing that could be the problem is that they may be a different size. Yes they can be a same shape, but there size if different. But, based on what the little excerpt above, I believe that both
are the same.
Hope this helps.
