Answer:
11
Step-by-step explanation:
1. Listing Information
The number is 10.999244792948.
Simply put, numbers below 5 are rounded down and numbers that are greater than or equal to five are rounded up.
The tenths place value in 10.999244792948 is 9.
2. Solving the Problem
With the previous information in mind, 9 is greater than 5. Because of this, 10.999244792948 should be rounded to 11.
To find f(2), put 2 where the variable is, then do the arithmetic. It might be easier to factor out x^2:
f(x) = (-6x-4)·x^2
f(2) = (-6·2-4)·2^2
= -16·4
= -64
Then the ordered pair (x, f(x)) for x=2 is
B. (2, -64)
Answer:
it depends (see below)
Step-by-step explanation:
<u>Exact Interest</u>
Exact interest is calculated on the basis of a 365-day year, so the exact interest on the loan would be ...
I = Prt = $7500·0.10·(85/365) = $174.66
Then the proceeds would be ...
$7500 -174.66 = $7,325.34 . . . . . matches first option
__
<u>Ordinary Interest</u>
Exact interest is calculated on the basis of a 360-day year, so the ordinary interest on the loan would be ...
I = Prt = $7500·0.10·(85/360) = $177.08
Then the proceeds would be ...
$7500 - 177.08 = $7,322.92 . . . . . matches last option
_____
I suggest you check your reference materials (text or course examples) to see what year length is expected to be used in this calculation. Some on-line references show it one way; others show it the other way.
Ella has 5 dollars in total
each stack has 50 cents and there's 10 stacks
.50*10 will equal 5.00 which is 5 dollars
For this case, we must find the inverse of the following function:
To find the inverse we follow the steps below:
We rewrite the denominator:
We exchange variables:
We solve for y:
We multiply on both sides of the equation by (y-7)
We subtract xy on both sides of the equation:
We add 1 to both sides:
We factor for y:
We divide both sides by (-5-x):
So, we have:
