Answer:
P = 309.35 + 2.31t
Step-by-step explanation:
The relation between the population of the USA and the time in years after 2010 will be linear as the increase in population is constant for every year since 2010 which is 2.31 million.
So, we can model the population P in million as a function of time(t) in years since 2010 as
P = 309.35 + 2.31t ....... (1)
Now, for t = 0 i.e. in the year 2010, the population will be obtained from equation (1) to be 309.35 million.

Answer:
The middle value of the interval is 4.58
Step-by-step explanation:
Consider the provided interval.
We need to find the value that is in the middle of the interval.
We can find the middle value of the interval by adding the upper and lower limit and divide the sum of the upper and lower limits by 2.
Here the upper limit is 3.27 and lower limit is 5.89.
Hence, the middle value of the interval is 4.58
Answer: H
Step-by-step explanation:
Can you take the quantity [ x + y ] and square it ?
Can you take the quantity [ x + 2y ] and square it ?
Then you should have no trouble with the square of (.9x + .8y) .
The square of any binomial (expression with 2 terms) is
(square of the first term)
+ (square of the second term)
+ 2 times (product of the terms) .
