Answer:

Yes. Every unique input has a unique output.

Step-by-step explanation:

Since every input has a different output, therefore it's a function. It's not a function when the input have more than 1 output. When graphing, make sure you take the vertical line test to see whether or not the graph is a function.

Water color painting

Length = 23 inches

Width = 11 inches

Mat that adds 1 inch to each side of the length and the width

Mat

Length = 23 + 1 = 24 inches

Width = 11 + 1 = 12 inches

What is the area of the mat?

Area of the mat = length × width

= 24 inches × 12 inches

= 288 inches ²

a cylindrical bucket has a radius of 6 inches and a height of 18 inches. What is the minimum number of buckets of water needed t

ivanzaharov [21]

Answer:

Minimum 7 buckets of water is needed to completely fill spherical storage tank.

Step-by-step explanation:

We are given the following in the question:

Cylindrical bucket:

Radius, r = 6 inches

Height = 18 inches

Volume of bucket = Volume of cylinder

$V = \pir^2 h \\V = 3.14\times (6)^2\times 18\\V =2034.72\text{ cubic inches}$

Spherical storage tank:

Radius, r = 15 inches

Volume of tank = Volume of sphere =

$V =\dfrac{4}{3}\pi r^3\\\\\V = \dfrac{4}{3}\times 3.14\times (15)^3\\\\V = 14130\text{ cubic inches}$

Number of baskets required =

$n = \dfrac{\text{Volume of tank}}{\text{Volume of bucket}}\\\\n =\dfrac{14130}{2034.72} = 6.94 \approx 7$

Thus, minimum 7 buckets of water is needed to completely fill spherical storage tank.

Please help me with this problem.

son4ous [18]

Answer:

y = 10/2x + 0

Step-by-step explanation:

Slope Int Form: y = m(slope)x + b(y-intercept)

The number before the x is the slope. To find the slope, count how far up or down and how far to the right or left. The b in the equation is the y-int so find the y-int of the graph.

Help please!!!! it makes so sense

Tamiku [17]

Answer:

(- $\frac{1}{5}$ , 0 )

Step-by-step explanation:

to find where the line crosses the x- axis, let y = 0 in the equation and solve for x

5x - 2(0) + 1 = 0

5x - 0 + 1 = 0

5x + 1 = 0 ( subtract 1 from both sides )

5x = - 1 ( divide both sides by 5 )

x = - $\frac{1}{5}$

the line crosses the x- axis at (- $\frac{1}{5}$ , 0 ) or ( - 0.2, 0 )
