Answer: 200
Step-by-step explanation:divide both by 2 then multiply
ANSWER. No, it is not equal.
Multiply 2(3-4y). It doesn’t equal it: 6-8y.
To find the height that the rocket has reached, we can use the following equation to calculate distance.
s = ut + 1/2 at²
s - distance - h
u - initial velocity - 64 ft/s x 0.3048 m/ft = 19.5 m/s
a - acceleration, since the rocket is travelling upwards against gravitational acceleration, its said to be deceleration. therefore value is -9.8 ms⁻²
t - time taken - t seconds
substituting values in the equation
h = 19.5 ms⁻¹ x t s - 1/2 x 9.8 ms⁻² x (t s)²
h = 19.5t - 4.9t²
Answer:
Step-by-step explanation:
There was a population of 108000 in a small town in 2002. Since then, the population has decreased at a rate of 2.5% each year.
Therefore, the population is decreasing at a compound rate of 2.5% each year.
Now, using the formula of compounding we can write if p is the population after t years, then
⇒ (Answer)
