The slope of this line is -1 you find this by using the slip formula of y-y over x-x find two points on the line so I used points (-2,2) and (-1,1) plug them into the formula to get the slope of -1 hope this helps:)

Please help! The volume of an inflated spherical water balloon is 121,500 pi millimeters to the third. What is the radius of the

irga5000 [103]

Answer:

The radius of the inflated spherical balloon is 45 millimeters.

Step-by-step explanation:

Volume of the spherical water balloon = 121,500 pi cubic millimeters

Let the radius of the balloon = r

Now, Volume of a Sphere = $\frac{4}{3} \pi r^{3}$

⇒ $\frac{4}{3} \pi r^{3} = 121,500 \pi$

On solving for the value of r, we get:

$r^{3} = \frac{121,500\times 3}{4} = 91125\\ \implies r = \sqrt[3]{91125}$

or, r = 45 millimeter

Hence, the radius of the inflated spherical balloon is 45 millimeters.

I need help on this please

Leya [2.2K]

The expression we have is:

$2xy\cdot xy^2$

And we are given some values for x and y:

$\begin{gathered} x=2 \\ y=4 \end{gathered}$

The first step will be to substitute the given values into the expression:

$2(2)(4)\cdot(2)(4)^2$

The next step is to solve 4^2 which is equal to 16:

$2(2)(4)\cdot(2)(16)$

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

$16\cdot32$

Solving this final multiplication we get the result:

$512$

Answer: 512
