Answer: 4+4
Step-by-step explanation:
6+2=8 4+4=8
Answer:
The answer is 16 hours
Step-by-step explanation:
The Reason why it is 16 hours is simply because it says in the question
"The moon is around 239,000 miles from Earth. How many hours would it take a rocket that can travel at 250 MILES PER MINUTE to travel to the moon? Round to the nearest hour.
"
So, turn 16 hours into minutes, 16 X 60 = 960 X 250 miles per min = 240,000, miles there you go! the answer is B!
Answer:
This simply means you add both functions. (f + g)(x) = f(x) + g(x). So the answer is -2x + -3x^2 - 7x = -3x^2 - 9x. please do not "carriage return" within question.
Complete question :
The development of AstroWorld ("The Amusement Park of the Future") on the outskirts of a city will increase the city's population at the rate given below in people/year t yr after the start of construction. 5,700√t + 11,000 The population before construction is 67,000. Determine the projected population 16 yr after the construction of the park has begun. people
Answer:
486,200
Step-by-step explanation:
Given that the rate of change in population is represented by the function:
f(t) = 5,700√t + 11,000
To get the original function, we take the integral of the rate function because the rate of change is obtained by taking the derivate of the original equation
f(t) = 5,700t^1/2 + 11,000
Taking the integral of f with respect to t:
∫(5,700t^1/2 + 11,000)
[5700t^(1/2 + 1)] / (1/2 + 1) + 11000t + C
[(5700t^3/2)/ 3/2] + 11000t + C
Where C = constant
If population before construction = 67000
Then C = 67000
t = time = 16 years
Substitute values into the original change equation:
[(5700(16)^3/2)/ 3/2] + 11000t + 67000
[(5700 * 64) / 1.5] + 11000(16) + 67000
243200 + 176000 + 67000
= 486,200
