(8x-2)/9=2
times both sides by 9
8x-2=18
add 2 to both sides
8x=20
divide both sides by 8
x=5/2

B is answer

A sphere has a volume of 4500 cubic inches. What is the radius off the shpere

Goshia [24]

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

$V = \frac{4}{3}\pi r^3$

Putting the known values

$4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636$

Taking cube root on both sides

$\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403$

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

The time, t, required to travel a fixed distance varies inversely as the

Lemur [1.5K]

You must travel at 42 mph for 4 hours

<em><u>Solution:</u></em>

Time varies inversely as rate of motion

Let "t" be the time required

Let "r" be the rate of motion

Then, we get

$t \propto \frac{1}{r}\\\\t = k \times \frac{1}{r}\\\\t = \frac{k}{r} -------- eqn 1$

Where, "k" is the constant of proportionality

<em><u>You travel 3 hours at a rate of 56 mph</u></em>

Substitute t = 3 and r = 56 in eqn 1

$3 = \frac{k}{56}\\\\k = 3 \times 56\\\\k = 168$

<em><u>Find the rate you must travel for 4 hours</u></em>

r = ? and t = 4

Substitute t = 4 and k = 168 in eqn 1

$4 = \frac{168}{r}\\\\r = \frac{168}{4}\\\\r = 42$

Thus you must travel at 42 mph for 4 hours

Answer:

See attachment for graph

Step-by-step explanation:

Given

$y = x^2 - 3$

Required

The graph of the equation

First, we determine the range of y

$x = -3$

$y = x^2 - 3 \to y = (-3)^2 - 3 = 6$

$(-3,6)$

$x = -2$

$y = (-2)^2 - 3 = 1$

$(-2,1)$

$x = -1$

$y = (-1)^2 - 3 = -2$

$(-1,-2)$

$x=0$

$y = 0^2 - 3 = -3$

$(0,-3)$

$x = 1$

$y= 1^2 - 3 = -2$

$(1,-2)$

$x = 2$

$y =2^2 - 3 = 1$

$(2,1)$

$x = 3$

$y = 3^2 - 3 = 6$

$(3,6)$
