Answer:
1.079 seconds
Step-by-step explanation:
You want to find t when H(t) = 15.
15 = -16t^2 +8t +25
10/16 = t^2 -1/2t . . . . . . subtract 24, divide by -16
10/16 + 1/16 = t^2 -1/2t +(1/4)^2 . . . . . add (1/4)^2 to complete the square
11/16 = (t -1/4)^2
t -1/4 = √(11/16) . . . . . take the positive square root
t = 1/4 +(√11)/4 = (1+√11)/4 . . . . use a common denominator
You would be 15 ft above the water at t = (1+√11)/4 ≈ 1.079 seconds.
Answer:
Your answer is DDDDDDDDD
Step-by-step explanation:
So,
Let x represent the first angle and y represent the second angle.
x + y = 90
x = y + 26
Substitute
y + 26 + y = 90
Collect Like Terms
2y + 26 = 90
Subtract 26 from both sides
2y = 64
Divide both sides by 2
y = 32
Substitute
x = 32 + 26
x = 58
Check
58 + 32 = 90
90 = 90 This checks.
58 = 32 + 26
58 = 58 This also checks.
The measure of one angle is 58° and the measure of the other angle is 32°.
