Answer:
26. B(t) = 500·1.075^t; B(6) ≈ $772
27. G(t) = 70·0.72^t; G(3) ≈ 26 g
Step-by-step explanation:
The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.
__
26. B(t) = 500·1.075^t
B(6) = 771.65
The balance after 6 years is about $772.
__
27. G(t) = 70·0.72^t
G(3) = 26.127
About 26 grams are left after 3 days.
Distance Firework B would have traveled after 0.25 seconds:
240 x 0.25 = 60 feet
Let x be the time that it will explode together:
60 + 240x = 340x
100x = 60
x = 60 ÷ 100
x = 0.6 sec
Firework A will explode at 0.6 seconds after it is launched
Firework B will explode at (0.6 + 0.25) 0.85 seconds after it is launched.

Answer: Firework B will explode at 0.85 seconds after it is launched.

Answer:
B) 110.92 u²
Step-by-step explanation:
to find the surface area, find the area of each side and add them together.
here are all 6 sides:
4.5 * 6.8
4.5 * 6.8
4.5 * 2.2
4.5 * 2.2
2.2 * 6.8
2.2 * 6.8
4.5 * 6.8 = 30.6
4.5 * 6.8 = 30.6
4.5 * 2.2 = 9.9
4.5 * 2.2 = 9.9
2.2 * 6.8 = 14.96
2.2 * 6.8 = 14.96
30.6 + 30.6 + 9.9 + 9.9 + 14.96 + 14.96
110.92
