The regular detergent has 57.6 ounces
h(t) = -16t2 + 64
Time to reach ground:
h(t) = 0
-16t2 + 64 = 0
Solve for t, keeping only the positive solution.
Time to fall 36 ft:
Since it is dropped from 64 ft, its height after falling 36 feet is 64-36=28 ft.
28 = -16t2 + 64
-16t2 + 36 = 0
Instead of finding a number multiplied by itself twice, you look for a number multiplied by itself three times. For example, 4 is the square root of 16 because 4*4=16. 4 is the cube root of 64 because 4*4*4=64
Δ ABC: ∠A = 32° ; a = 19 (side a opposed to angle A)
and side b = 12 (opposed to Angle B)
Law of sine's
:
(sin A)/19 = (sin B)/12, but sin A = sin 32° = 0.53
0.53/19 = (sin B)/12
and sin B = (0.53 x 12) / 19 → sin B = 0.335.
Calculate ∠ B:
sin B = 0.335. → sin⁻¹(0.335) = 19.57° ≈ 20°
∠ A = 32°, ∠B ≈ 20° and ∠C = 180° -32°-20° = 128°
Now that we have got the 3 Angles, let's find c, the 3rd side of the Δ
sin 32/19 = sin 128/c
0.03 = 0.788/c and c ≈ 26
+a = 19, b = 12 an c = 26
