Y=8/x-3 Identify the set of values x for which y will be a real number

Mathematics

Alex787 [66]3 years ago
6 0

The set of values of x for which y will be a real number according to Y=8/x-3 includes all real numbers except x = 3.

<em>Real numbers in mathematics include the positive and negative integers and fractions (or rational numbers) and also the irrational numbers.</em>

  • In essence, the expression Y=8/x-3 only ceases to yield a real number value for y if the denominator becomes zero.

When the denominator becomes zero, the value of y becomes undefined and thus is not a real number.

Therefore, if we set;

  • x - 3 = 0

  • x = 3.

Consequently, the set of values of x for which y will be a real number according to Y=8/x-3 includes all real numbers except x = 3.

Find the height of a square pyramid that has a volume of 12 cubic feet and a base length of 3 feet. 1.5 feet 2 feet 3 feet 4 fee
zaharov [31]
So the pyramid looks like the one in the picture below.

notice, the bottom of the pyramid is a square, thus is called that, and each side is 3 units long, thus

\bf \textit{volume of a pyramid}\\\\&#10;V=\cfrac{1}{3}Bh~~&#10;\begin{cases}&#10;B=area~of\\&#10;\qquad its~base\\&#10;h=height\\&#10;----------\\&#10;V=12\\&#10;B=\stackrel{3\times 3}{9}&#10;\end{cases}\implies 12=\cfrac{(9)h}{3}\implies 12=3h&#10;\\\\\\&#10;\cfrac{12}{3}=h\implies 4=h

What is the total cost of a sweatshirt if the regular price is $45 and the sales tax 5.75%
bagirrra123 [75]

Beth purchased $21.25 worth of groceries. The sales tax rate is 7.5%. What was her total bill?

The tax is calculated by 0.075 * 21.25 = 1.59375 or $1.59. So the total bill is the cost of items purchased plus tax, which is $21.25 + $1.59 = $22.84.


Back to your question:

What is the total cost of a sweatshirt if the regular price is $45 and the sales tax 5.75%

The tax is calculated by 0.0575 * 45 = 2.5875 or $2.59. So the total bill is the cost of items purchased plus tax, which is $45 + $2.59 = $47.59

Hope this helped! Good luck!
