Answer:

C

Step-by-step explanation:

Diameter is 3 feet, and the radius is half the diameter.

Radius = 3/2 = 1.5 feet

Circumference

2 × π × 1.5
3π

Distance travelled in 20 rotations

20 x 3π
60π ft

Log y=9.
e

Drop first and make it logs base.
Y sits beside it
And 9 becomes answer
Therefore e = certain #
And to the power (which is Y) will give you answer of 9

What is the slope of the line that passes through the points R(11, 6) and S(9, -1)?

vodomira [7]

Answer:

7/2

Step-by-step explanation:

The slope of the line is given by

m = (y2-y1)/(x2-x1)

= (-1-6)/(9-11)

= -7/ -2

= 7/2

A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 55 seconds, th

True [87]

Answer:

$y=3x+4$

Step-by-step explanation:

Let y be the amount of water in the bottle x seconds after the faucet was turned on.

We have been given that the gauge on the bottle indicates that it contains 19 ounces of water after it has been filling for 5 seconds. After it has been filling for 11 seconds, the gauge indicates the bottle contains 37 ounces of water.

We have two points on the line $(5,19)$ and $(11,37)$ .

Let us find slope of the line passing through these points.

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{37-19}{11-5}$

$m=\frac{18}{6}$

$m=3$

We will write our required equation in slope-intercept form $y=mx+b$ , where, m represents slope and b represents the y-intercept.

Let us find y-intercept by substituting $m=3$ and coordinates of point $(5,19)$ in slope intercept form.

$19=3\cdot 5+b$

$19=15+b$

$19-15=15-15+b$

$4=b$

Therefore, our required equation would be $y=3x+4$ .
