$\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ V=1767.1 \end{cases}\implies 1767.1=\cfrac{4\pi r^3}{3}\implies 5301.3=4\pi r^3 \\\\\\ \cfrac{5301.3}{4\pi }=r^3\implies \sqrt[3]{\cfrac{5301.3}{4\pi }}=r\implies 7.4999\approx r$

If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w circle r) (x)?

VashaNatasha [74]

Answer:

$(-\infty, 0)$

Step-by-step explanation:

(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]

We have that:

$r(x) = 2 - x^{2}$

$w(x) = x - 2$

Composite function:

$w(r(x)) = w(2 - x^{2}} = 2 - x^{2} - 2 = -x^{2}$

$-x^{2}$ is a negative parabola with vertex at the original.

So the range(the values that y assumes), is:

$(-\infty, 0)$

What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?

musickatia [10]

Answer:

$219456$

Step-by-step explanation:

It must end in $0,2,4,6,8$ (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).

The digit sum is $2+A+9+4+5+B=20+A+B$ .

We want to make $A$ as low as possible because it's a higher digit than $B$ .

If $A$ is as low as possible, we have that the sum is $20+0+7=27$ . Uh-oh. $B$ has to be even! So $A=0$ doesn't work.

If $A=1$ , we have that the sum is $20+1+6=27$ . Yay!

So, the answer is $\boxed{219456}$

2. Sketch the graph: 4y – 3x = 12.

goblinko [34]

Answer:

see below

Step-by-step explanation:

A graphing calculator is useful for this.

__

To find the x-intercept, set y=0 and solve for x:

0 -3x = 12

x = -4 . . . . . . divide by -3

To find the y-intercept, set x=0 and solve for y:

4y - 0 = 12

y = 3 . . . . . . divide by 4

Plot the x- and y-intercepts on their respective axes and draw a line through them.

To find this answer, we replace x with 0 in the g(x) function

g(x) = -2x

g(0) = -2*0

g(0) = 0
