The function is in slope-intercept form y=mx+b, where m is the slope and b is the y-intercept.
y = (1/3)x + -4.
we know that the y-intercept=-4, so we can rue out the top left and bottom left graphs.
m=slope= (1/3). We know the slope is positive, so we can rule out the bottom right graph.

The top-right graph is the correct one.

The volume of a sphere is 28/3 times it surface area, find the surface area

pentagon [3]

Answer:

615.44 units squared

Step-by-step explanation:

Let the volume and surface area of the sphere be V and S respectively.

$\therefore V = \frac{28}{3} \times S\\\\\therefore \frac{4}{3} \pi {r}^{3} = \frac{28}{3} \pi {r}^{2} \\ \\ \frac{ {r}^{3} }{ {r}^{2} } = \frac{28\pi}{3} \times \frac{3}{4\pi} \\ \\ r = 7 \: units \\ \\ \because S = 4\pi {r}^{2} \\ \\ \therefore \: S = 4 \times 3.14 \times {7}^{2} \\ \\ \therefore \: S = 12.56 \times 49 \\ \\ \therefore \: S =615.44 \: {units}^{2}$

im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to t

deff fn [24]

Answer:

Step-by-step explanation: How do you find the 3rd angle of a triangle?

Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.

The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.

Solve the equation below pls show your work no links pls. <img src="https://tex.z-dn.net/?f=%289%5E%7B2%7D%20%29%5E%7B-1%2F3

Given :-

$(9^{2} )^{-1/3}$

To Find :-

To solve the expression .

Solution :-

Given expression to us is ,

$(9^{2} )^{-1/3}$

We know that ,

$9 = 3^2$

So our expression becomes ,

$\{ (3^2)^2\}^{\frac{-1}{3}}$

And , $(a^m)^n =a^{mn}$ . Using this ,

$(3^4)^{\frac{-1}{3}}$

Again using the same law ,

$3^{\frac{-4}{3}}$

We know that , $a^{-m}=\frac{1}{a^m}$ . Therefore ,

$(3^{-4})^{\frac{1}{3}}$

$\\\bigg( \dfrac{1}{3^4}\bigg)^{1/3}$

$\\ \dfrac{1}{\sqrt[3]{3^4}}$

Simplify ,

$\dfrac{1}{3\sqrt[3]{3}}$

This is the simplified expression.

I hope this helps.

Can someone please help

atroni [7]

Answer:

Step-by-step explanation:

$\frac{5}{24}+\frac{2}{3-x}=\frac{1}{4}\\\\\frac{5}{24}-\frac{1}{4}=\frac{-2}{3-x}\\\\\frac{5}{24}-\frac{1*6}{4*6}=\frac{-2}{3-x}\\\\\frac{5-6}{24}}=\frac{-2}{3-x}\\\\\frac{-1}{24}}=\frac{-2}{3-x}\\\\\\(-1)*(3-x)=(-2)*24\\\\-1*3-(-1)*x = -48\\\\-3 + x = -48\\\\x = -48 + 3\\\\x = -45$

x = -45

Help please. Im stuck

LUCKY_DIMON [66]

Answer:

16 units squared

Step-by-step explanation:

First, calculate the distance between (0, 0) and (0, 4). The distance is in y, so there are 4 units in-between.

Next, calculate the distance between (0, 0) and (4, 0). This time, the distance is in x, but it is still four.

We know the dimensions of the shape are 4x4 so we just multiply.

4*4=16
