Answer:
12,600
Step-by-step explanation:
Im taking this to mean (2 x^7 y)^2 (y^5)^3
= 4x^14 y^2 * y^15
= 4x^14 y^17 which is option 4
Answer:
42 miles
Step-by-step explanation:
Area of the base = 1/2 * 10 * 5sqrt3 = 25 sqrt3
Total surface area = 25 sqrt3 + 3 * 1/2 * 10 * slant height = 214.5
25 sqrt3 + 15h = 214.5
15h = 214.5 - 25 sqrt3
h = (214.5 - 25sqrt3() / 15
= 11.41 cm to nearest hundredth
