Length of diameter

√(2-2)²+(2-12)²
√(-10)²
10units

Length of radius=10/2=5

3x²-34x-24=0
(x-12)(3x+2)=0
x=12 or -2/3

Solution set

Answer:

See below ~

Step-by-step explanation:

Question 18

Diameter = Difference in y-coordinates
Diameter = 12 - 2 = 10
We know : Radius = Diameter/2
Radius = 10/2
Radius = 5 cm
(1) 5 cm

Question 19

3x² - 34x - 24 = 0
(3x + 2)(x - 12) = 0
Solution set = {-2/3, 12}
(3) {-2/3, 12}

What is the slope of the line described 16x = 4y + 1

Dvinal [7]

Answer: The slope is 4x.

Step-by-step explanation: First, subtract 4y from both sides to get 16x-4y=1. Next, subtract 16x from both sides to get -4y=-16x+1. Finally, divide all terms by -4 to get y=4x-0.25. The slope is represented by 4x.

How can you tell how many solutions a linear equation will have by looking at the equation?

Solnce55 [7]

Answer:

A system of two equations can be classified as follows

Step-by-step explanation:

If the slopes are the same but the y-intercepts are different, the system has no solution. If the slopes are different, the system has one solution. If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.

Louis built a swimming pool. The depth of the swimming pool is 5 feet. What is the volume of water that it will take to fill the

julia-pushkina [17]

Answer:

For a rectangular prism-like swimming pool: $V = w\cdot l \cdot h$ . $V = 360\,ft^{3}$ when $h = 5\,ft$ , $l = 12\,ft$ and $w = 6\,ft$ .

Step-by-step explanation:

Let assume that swimming pool has a rectangular base and depth is the same at any point at the bottom. In addition, let $w$ and $l$ be the width and length of the swimming pool. Then, the volume needed to fill the swimming pool is:

$V = w\cdot l \cdot h$ , where $h$ is the depth of the pool.

Let be $h = 5\,ft$ , $l = 12\,ft$ and $w = 6\,ft$ . The volume of the swimming pool is:

$V = (6\,ft)\cdot (12\,ft)\cdot (5\,ft)$

$V = 360\,ft^{3}$
