Answer:
<u>First find x and y at given parameters:</u>
- x = (v₀cosθ)t = (123 cos60°)t = 61.5t
- y = h + (v₀sinθ)t - 16t² = 0 + (123 sin 60°)t - 16t² = 106.52t - 16t²
<u>Maximum height is at vertex. Time is:</u>
- t = -106.52/-32 = 3.3 seconds
<u>Maximum height is:</u>
- y = 106.52*3.3 - 16(3.3)² = 177.3 ft
<u>Horizontal distance:</u>
<u>Time to hit the ground:</u>
- 106.52t - 16t² = 0
- 16t = 106.52 (t = 0 is discounted)
- t = 106.52/16
- t = 6.7 seconds

Total: 54
Boys: 36
Girls: x
54 - 36 = x
x = 18
There would be 18 girls at the swim meet
Answer:
$6500
Step-by-step explanation
x = amount ($) loaned at 6%
then
18000-x = amount ($) loaned at 14%
.06x + .14(18000-x) = 2000
.06x + 2520-.14x = 2000
2520-.08x = 2000
-.08x = -520
x = $6,500
