Answer

If we had a sale price of 30% off of $1,050then the sale price is 70% of $1,050 or 0.7(1050) Then we add 7% sales tax to that making thefinal price paid 107% of [0.7(1050)] ... 1.07[0.7(1050)] = $786.45

Which equations represent the asymptotes of the hyperbola (x-1)^2/36-(y-2)^2/64=1 ?
allochka39001 [22]

Answer:

4x+3y=10 and  4x-3y=-2

Step-by-step explanation:

The asymptote equation of a translate hyperbola with equation \frac{(x-h)^2}{b^2}-\frac{(y-k)^2}{a^2}=1 is y=\pm\frac{b}{a}(x-h)+k

The given hyperbola has equation: \frac{(x-1)^2}{36}-\frac{(y-2)^2}{64}=1

Or \frac{(x-1)^2}{6^2}-\frac{(y-2)^2}{8^2}=1

Comparing to \frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1

We have  a=6 and b=8, h=1 and k=2.

We substitute this values to get:

y=\pm\frac{6}{8}(x-1)+2

y=\pm\frac{4}{3}(x-1)+2

3y=\pm4(x-1)+6

We split the plus or minus sign to get:

3y=4x-4+6

3y=4x+2

3y-4x=2

Or

3y=-4(x-1)+6

3y=-4x+4+6

3y+4x=10

Why is 5 to the 2 power also read as 5 squared
Vikki [24]

The reason for this has to do with finding the area of a square. When you are looking for the area of a square, you use the rectangle formula (since a square is also a rectangle).

The formula is Area = Length * Width

However, since in a square, the length and width are the same, both get changed to the word "Side". As a result, we get the following formula.

Area = Side * Side

This can be simplified to:

Area = Side^2.

Since each number to the second power also shows the area of a square with that given length sides, it can also be called "squared".

If the sales tax rate is 9.75 % in California, then how much would you pay in Los Angeles for a pair of shoes that cost $39.00?
tankabanditka [31]

Answer:

$42.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9.75%/100 = 0.0975 per year.

Solving our equation:

A = 39(1 + (0.0975 × 1)) = 42.8025

A = $42.80

The total amount accrued, principal plus interest, from simple interest on a principal of $39.00 at a rate of 9.75% per year for 1 years is $42.80.
