Answers

Answer 1

Answer: since there are 90 seconds in a minute and a half you multiply 90 by 2 getting 270 then you subtract 270 from 2000 and you get 1730 meters which is your answer hope this helps!

Determine the volume of the square pyramid below h-4 b1-6 b2-6 144 square units 36 square units 72 cubic units 48 cubic units

Answers

Answer:

V = 48 cubic units

Step-by-step explanation:

$V=b^(2) (h)/(3)$ Use this equation to find the volume

$V=6^(2) (4)/(3)$ Simplify the exponent

$V=36((4)/(3))$ Multiply

V = 48 cubic units

A country’s population doubled in 45 years. what was the exponential growth rate

Answers

Final answer:

The exponential growth rate is approximately 1.56% per year for a population to double in 45 years.

Explanation:

To calculate the annual growth rate for a population that doubles in a specific time period, we can use the rule of 70, which is a formula for estimating the time it takes for an investment or population to double given a constant growth rate. The rate of growth (r) can be calculated as r=70/t, where t is the time in years.

In this case, the country's population doubled in 45 years. So, the annual growth rate would be r=70/45

= 1.56%.

Therefore, the exponential growth rate that caused the country's population to double in 45 years is approximately 1.56% per year.

A rocket is launched from the ground. The function h(t)= -4.9t^2 +180t models the height of a rocket launcher from the ground t seconds after it is launched. If all other factors remain the same, which of the following function models the height of a rocket above the ground after t seconds if it is launched from a platform 100 feet in the air? (1) h(t) = -4.9t^2 +280t (2) h(t) = -4.9t^2 +180t -100 (3) h(t) = -4.9t^2 +180t +100(4) h(t) = -4.9t^2 +180 (t+100)
