The speed of the ball is
ds/dt = 32t
At t =1/2 s
ds/dt = 16 ft/s
The distance from the ground
50 - 16(1/2)^2 = 46 ft
The triangles formed are similar
50/46 = (30 + x)/x
x = 345 ft
50 / (50 - s) = (30 + x)/x
Taking the derivative and substituing
ds/dt = 16
and
Solve for dx/dt
Answer: 6.71 × 10^6 people
Step-by-step explanation:
Given that the population of New Zealand was approximately 4.43million people. In the same year, the population of Belgium was approximately 11.14 million people.
The difference in number of population will be
(11.14 - 4.43) millions
= 6.71 millions people
Expressing the answer by using scientific notation will be
6.71 × 10^6 people.
Therefore, 6.71 × 10^6 people live in Belgium than in New Zealand
The answer is currently A so yep thats the answer ok
Answer:
I believe it is C i am very sorry if it's wrong
54,273 = A * 1.70^6 where A is the initial number
A = 54273/1.70^6 = 2248
