Answer:

V = 4/3 pi r^3 for a sphere

Step-by-step explanation:

You can't a circle is a two dimensional object.

What is the value of the expression “three less than the quotient of ten and a number, increased by six” when n = 2?

alisha [4.7K]

Answer:

Step-by-step explanation:

The given expression is "three less than the quotient of ten and a number, increased by six”

The quotient of ten and a number increased by six is translated into mathematical expression as:

$\frac{10}{n}+6$

Three less than the quotient of ten and a number, increased by six is

$(\frac{10}{n}+6)-3$

When we substitute n=2, we get:

$(\frac{10}{2}+6)-3$

Divide to get:

$(5+6)-3$

Add to get:

$11-3$

Subtract

$8$

5-2x=15

 $5-2x=15 \\ \\ -2x= 15-5 \\ \\ -2x= 10 \\ \\ x= \dfrac{10}{-2} \to \boxed{x= -5}$

Write an equation in standard form of the line that passes through the given point and has the given slope. (5,0) m=4/3

sveticcg [70]

$\text{The standard form of a line:}\ Ax+By=C$

$\text{The point-slope form:}$

$y-y_1=m(x-x_1)$

$\text{We have the point (5, 0) and the slope}\ m=\dfrac{4}{3}$

$\text{substitute:}\\\\y-0=\dfrac{4}{3}(x-5)\qquad|\text{use distributive property}\\\\y=\dfrac{4}{3}x-\dfrac{20}{3}\qquad|\text{multiply both sides by 3}\\\\3y=4x-20\qquad|\text{subtract 4x from both sides}\\\\-4x+3y=-20\qquad|\text{change the signs}\\\\\boxed{4x-3y=20}$
