Answer:

x=-5

Step-by-step explanation:

distribute -2 [ -4x-18=2 ]

add 18 to both sides [ -4x = 20 ]

divide both sides by -4 [ x=-5 ]

Here is the complete question

Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and 5 inches tall. What was the volume of each cup?

Volume of a cone = $\frac{1}{3}$ πr²h

π = 22/7

Radius = diameter / 2 = 6 /2 = 3 inches

(1/3) x (3^2) x (22/7) x 5 = 47.14 in³

Leokris [45]

Answer:

$E(x)=1$

Step-by-step explanation:

From the question we are told that:

Sample mean 1 $\=x_1=$9$

Sample mean 1 $\=x_2=$8$

Sample standard deviation 1 $\sigma_1 = $2$

Sample standard deviation 1 $\sigma_2 = $1$

Generally the equation for Point estimate is mathematically given by

$E(x)=\=x_1-\=x_2$

$E(x)=9-8$

$E(x)=1$

Determine the vertical asymptote for the rational function f of x equals quantity x minus 4 end quantity divided by quantity 3 t

Anastasy [175]

Answer:

vertical asymotote at $x=\frac{-2}{3}$

Step-by-step explanation:

$f(x)= \frac{x-4}{3x+2}$

vertical asymptote is the line where the graph goes close to the line but does not cross it.

To find vertical asymptote, we set the denominator =0 and solve for x

denominator is 3x+2

set 3x+2=0

Subtract 2 on both sides

$3x=-2$

divide both sides by 3

$x=\frac{-2}{3}$

vertical asymotote at $x=\frac{-2}{3}$
