Answer:

$2.69

Step-by-step explanation:

Distribution method:

.20(2.50, 4.95, 6.00)

(0.50, 0.99, 1.20)

Now add them up.

Non-distribution method:

$2.50 x .20 = 0.50

$4.95 x .20 = 0.99

$6.00 x .20 = 1.20

Add them up

Passes through<br> (-8, 3) and (8, -1).
lawyer [7]

Answer:

Slope = Y2 -Y1 / X2 - X1

Slope = -1 -3 / 8 --8

Slope = -4 / 16

Slope = -1 / 4

To calculate the equation we fill in this equation:

(y - y1) = slope • (x -x1)

We only need to choose 1 point so we'll choose (-8, 3)

(y - 3) = -1 / 4 * (x --8)

So the Equation equals

y = -1 / 4 x -2 + 3

y = -1 / 4x +1

2. A sphere has surface area 16π. Find the radius of the sphere.
KiRa [710]

Answer:

The answer to your question is: 2.29 units

Step-by-step explanation:

Data

Volume = 16π

radius = ?

Formula

V = \frac{4}{3}π r^{3}

Process

                         16 π =  \frac{4}{3}π r^{3}

                         \frac{16(3)}{4} = r^{3}

                         r³ = 12

                        r = 2.29
