Answer:

V = 4.84 × 10⁷ km³

Step-by-step explanation:

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

Where r = 3400 km

V = $\frac{4}{3} (3.14)(3400)^3$

V = (4)(3.14)(11,560,000)/3

V = 48,422,415 km³

Upto 3 sfs:

V = 4.84 × 10⁷ km³

A movie rental store rents DVDs for $3.50 each .How much will the store make after it rents 22 DVDs

frez [133]

Hey there!

To solve this question simply multiply 3.50 by 22.
Since 3.50 is the cost for 1 DVD, 22 DVD's will cost 77 dollars.

3.50 x 22 = 77

So, the store makes 77 dollars after renting 22 DVDs

Write an equation in the variables x and y for the line that passes through the point (4, 7) and that is perpendicular to the li

Brrunno [24]

First of all, we need to find the slope of the given line, writing it in the $y=mx+q$ form and reading the $m$ coefficient:

$2x + 2y = 14 \iff 2y = -2x + 14 \iff y = -x+7$

So, the slope is $-1$

If a line with slope $m'$ is perpendicular to a line with slope $m$ , the following relationship holds:

$mm' = -1$

So, the slope of our line must satisfy

$m(-1) = -1 \iff m=1$

So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope $m$ and a point $(x_0,y_0)$ of a given line, its equation is given by
