Answer:
- a) 6.5 seconds
- b) 13 seconds
- c) 679 ft
Step-by-step explanation:
<u>Given function:</u>
a) <u>Maximum height is the vertex.</u> The ball reaches the maximum after:
- h = -208/2(-16) = 6.5 seconds
b) <u>Time the ball was in the air:</u>
Solving we get approximately t = 13 seconds
c) <u>Maximum height is at vertex, we found t above:</u>
- h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft
So the answer would be <span>x=2 y=5</span>
Answer: A) 24.8 B) 8.8
Step-by-step explanation:
You could try using cosine ( adj. over hypotenuse) on a calculator.
To determine if these line segments are congruent you can find the distances between the x values and the y values for each set of points.
(-1, 10) and (-5, 2). 4 on x axis and 8 on the y axis.
(9, -7) and (1, -3). 8 on the x axis and 4 on the y-axis.
This means they are congruent. Each triangle would have the same two side lengths making the hypotenuse the same.
