Can someone tell me all of the rational numbers

Mathematics
1 answer:
Vaselesa [24]3 years ago
3 0

Answers: The rational numbers in that list are:

  • \sqrt{2.25}
  • 1
  • -79
  • 0.3125

Recall that an irrational number cannot be written as a simple fraction, so the numbers that can be written in a simple fraction are the ones that are rational. Thus, the numbers in the previous list are rational because you can convert them into simple fractions.

Identify the domain and range of y = 4x - 5 + 3
Zepler [3.9K]

Answer:

\huge\boxed{\text{Domain:}\ D=\mathbb{R}=(-\infty;\ \infty)}\\\boxed{\text{Range:}\ R=\mathbb{R}=(-\infty;\ \infty)}

Step-by-step explanation:

y = 4x - 5 + 3 = 4x - 2

It's an equation of a line in the slope-intercept form.

y = 4x - 2 → f(x) = 4x - 2 - it's a lienar function.

The domain of a linear function is the set of all real numbers.

If a slope of linear function is different than 0, then the range is the set of all real numbers.

One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cyl
mojhsa [17]

The correct equation is:

216 = \frac{7}{8} \times x - 8

The volume of second cylinder is 256 centimeter cubed

<em><u>Solution:</u></em>

Given that,

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder

The first cylinder’s volume is 216 centimeter cubed

From given,

Let "x" be the volume of second cylinder

Therefore,

Volume of first cylinder = 7/8 of the volume of a second cylinder - 8

216 = \frac{7}{8} \times x - 8

216 = \frac{7x}{8}-8\\\\216 = \frac{7x-64}{8}\\\\7x - 64 = 8 \times 216\\\\7x - 64 = 1728\\\\7x = 1728 + 64\\\\7x = 1792\\\\Divide\ both\ sides\ by\ 7\\\\x = 256

Thus the volume of second cylinder is 256 centimeter cubed
