Answer:

Irrational.

Step-by-step explanation:

Rational means that it is a whole number and can be written as a fraction. That doesn't apply for square rooted numbers. So, $\sqrt{62}$ is irrational.

(2x-7)-(4x^2+6x-3)+(x^2+4)

masha68 [24]

Answer:

$-3x^2-4x$

Step-by-step explanation:

Simplify:

$\left(2x-7\right)-\left(4x^2+6x-3\right)+\left(x^2+4\right)$

$=2x-7-\left(4x^2+6x-3\right)+x^2+4$

Group same factor:

$=-\left(4x^2+6x-3\right)+x^2+2x-7+4$

Add :

$=-\left(4x^2+6x-3\right)+x^2+2x-3$

Apply the distributive law: -(a+b) = -a - b

$-\left(4x^2+6x-3\right)=-4x^2-6x+3$

$=-4x^2-6x+3+x^2+2x-3$

Group same factor:

$=-4x^2+x^2-6x+2x+3-3$

Subtract:

$=-4x^2+x^2-6x+2x$

Add:

$=-3x^2-6x+2x$

Group same factor:

$=-3x^2-4x$

Hence answer = $-3x^2-4x$

Sketch the graph of each rational function showing all the key features. Verify your graph by graphing the function on

leva [86]

Answer:

Rational Function

Step-by-step explanation:

Gives the function:

$f(x) = \frac{x-2}{3x-2x^2}$

It has the following,

Domain

x∈ $\mathbb{R}$ : $x\neq 0, x\neq 3/2$

Range

$f \in \mathbb{R} : f \leq -1, f \geq -\frac{1}{9}$

End behaviour

As x $x \rightarrow \infty, y \rightarrow 0$

Horizontal and Vertical Asymptote

Vertical $x = 0, x=3/2$

Horizontal $y = 0$

<em>x-intercept: (2,0)</em>

<em>y-intercept: none</em>

The prism shown has a volume of 3,024 cm3.

Arlecino [84]

Answer:

14cm

Step-by-step explanation:

To find volume, you need to multiply the height width and length together. So when you have one missing measurement, to find it, you need to do the same steps except for put a variable for the missing measurement. And continue to do the problem as you would. Here is how I solved it.

V=12x18xH

3024=216xH (216 is 12x18)

Then to find the missing side, do 3024/216 which equals 14.
