Is y=x2-1 a linear equation

Inga [223]

Y=x2-1 is not a linear equation only because for it to be an linear equation it would have to be 2x-1=y or y=2x-1

Identify the diameter of Q given that a= 169 pie in2

Kaylis [27]

Answer:

the diameter will be D=26 in.

Step-by-step explanation:

The area of a circle is given by:

$A=\pi R^{2}$ (1)

Where:

A is the area
R is the radius of the circle

Now, we know that A = 169 π in²

So, we just need to use equation 1 to find R.

$169\pi = \pi R^{2}$

$R=\sqrt{169}$

$R=13 \: in$

Therefore, the diameter will be D=2*R=26 in.

I hope it helps you!

If r and s are positive integers, is \small \frac{r}{s} an integer? (1) Every factor of s is also a factor of r. (2) Every prime

Yuri [45]

Answer:

If statement(1) holds true, it is correct that $\small \frac{r}{s}$ is an integer.

If statement(2) holds true, it is not necessarily correct that $\small \frac{r}{s}$ is an integer.

Step-by-step explanation:

Given two positive integers $r$ and $s$ .

To check whether $\small \frac{r}{s}$ is an integer:

Condition (1):

Every factor of $s$ is also a factor of $r$ .

$r \geq s$

Let us consider an example:

$s = 5^2 \cdot 2\\r = 5^3 \cdot 2^2$

$\dfrac{r}{s} = \dfrac{5^3\cdot2^2}{5^2\cdot2} = 10$

which is an integer.

Actually, in this situation $s$ is a factor of $r$ .

Condition 2:

Every prime factor of s is also a prime factor of r.

(But the powers of prime factors need not be equal as we are not given the conditions related to powers of prime factors.)

Let

$r = 2^2\cdot 5\\s =2^4\cdot 5$

$\dfrac{r}{s} = \dfrac{2^3\cdot5}{2^4\cdot5} = \dfrac{1}{2}$

which is not an integer.

So, the answer is:

If statement(1) holds true, it is correct that $\small \frac{r}{s}$ is an integer.

If statement(2) holds true, it is not necessarily correct that $\small \frac{r}{s}$ is an integer.

rewona [7]

Prime: 3,17,31

Composite: 10,24,38

Prime numbers can only be divided by one and itself, while composite numbers can be divided by a number other than one and itself.
