What are the slope and the y-intercept of the linear function that is represented by the equation y=-10x+1
RUDIKE [14]
<h3>Answer:</h3>

The slope is -10 and the y-intercept is 1.

<h3>Explanation:</h3>

This function is written in slope-intercept form, which is y=mx+b.  In this form, m is the slope and b is the y-intercept.

In this case, m=-10 and b=1, so those are the answers to this problem.

what is the ratio for the volumes of two similar spheres given that the ratio of their radii is 4:7 A.)343:64 B.)49:16 C.)16:49
quester [9]

Answer:

Volume of the similar sphere be 64 :343 .

Option (D) is correct.

Step-by-step explanation:

Formula

Volume\ of\ a sphere = \frac{4}{3}\pi r^{3}

As given

The volumes of two similar spheres given that the ratio of their radii is 4:7 .

Let us assume that the x be the scalar multiple of the radi .

Radius of first sphere = 4x

Radius of second sphere = 7x

Putting the values in the formula

Volume\ of\ first\ sphere = \frac{4}{3}\pi\times 4x\times 4x\times 4x

Volume\ of\ first\ sphere = \frac{4}{3}\pi\times 64x^{3}

Volume\ of\ second\ sphere = \frac{4}{3}\pi\times 7x\times 7x\times 7x

Volume\ of\ second\ sphere = \frac{4}{3}\pi\times 343x^{3}

Thus

\frac{Volume\ of\ first\ sphere}{Volume\ of\ second\ sphere} = \frac{\frac{4\pi\times 64x^{3}}{3}}{\frac{4\pi\times 343x^{3}}{3}}

\frac{Volume\ of\ first\ sphere}{Volume\ of\ second\ sphere} = \frac{64}{343}

Therefore the ratio of the volume of the similar sphere be 64 :343 .

Option (D) is correct .
