<span>The square mile (abbreviated as sq mi and sometimes as mi2) is an imperial and US unit of measure for an area equal to the area of a squareof one statute mile. It should not be confused with miles square, which refers to the number of miles on each side squared.</span>
Answer:
$6370
Explanation:
The simple interest formula gives us the final amount A given the principal amount P:

where r is the interest rate and t is the time interval.
Now in our case we have
P = 2800
r = 4.25/100
t = 30 years
therefore, the above formula gives

which simplifies to give

Hence, the account balance after 30 years will be $6370.
(94 * 8.9) - 14
836.6 - 14
822.6 = answer

Answer: The required value of f(3) is 81.
Step-by-step explanation: We are given the following function :

We are to find the value of f(3).
Substituting x = 3 in equation (i), we get

Thus, the required value of f(3) is 81.
Answer:
To ensure uniformity on an exam
Or
To test whether you can distinguish between the two formats
Step-by-step explanation:
Standard form is when a straight line equation is rearranged in the form:

Therefore y=2x+4 in standard form is

The slope-intercept form is when a a straight line equation is written in the form:

where m is the slope and c is the y-intercept.
The given equation is

This is already in slope-intercept form:
The standard form and slope-intercept forms are just formats.
Your instructor may restrict you to leave your answer in one of these formats maybe for uniformity on a test.
You may also decide to rewrite an equation in slope-intercept form, so that you can easily identify the slope and y-intercept easily for graphing purpose.
