The ratio of the heights of two similar solids is 6:11. Find the ratio of their surface areas.

vaieri [72.5K]

Answer:

The ratio of surface areas is 36:121.

Step-by-step explanation:

We have, the ratio of the heights of two similar solids is 6:11. It is required to find the ratio of their surface areas. As the two solids are similar, it means that the ratio of surface areas of solids is directly proportional to the square of their heights such that,

$\dfrac{S_1}{S_2}=(\dfrac{h_1}{h_2})^2\\\\\dfrac{S_1}{S_2}=(\dfrac{6}{11})^2\\\\\dfrac{S_1}{S_2}=\dfrac{36}{121}$

So, the ratio of surface areas is 36:121.

Write an equation in slope-intercept form of the line satisfying the given conditions.

Yuri [45]

Answer:

y=-2x+2

Step-by-step explanation:

Given line is-

x-2y=7

we know,

equation of line perpendicular to ax+by=c is bx-ay=k

So, equation of line perpendicular to x-2y=7

is given by -2x-y=k

Now, the line -2x-y=k passes through (5,-8)

So, we get

-2(5)-(-8)=k

or, -10+8=k

or, -2=k

So, k=-2

Using the k value we get,

Equation of the line is-

-2x-y=-2

multiplying by -1

2x+y=2

or, y=-2x+2

This is the slope intercept form of the line.
