Answer:

The maximum width of the pool must be 38 ft

Step-by-step explanation:

Let

y -----> the length of the swimming pool

x ----> the width of the swimming pool

The perimeter of the swimming pool is

$P=2(x+y)$

we have

$y=22\ ft$

substitute

$P=2(x+22)$

$P=2x+44$

Remember that

The perimeter of the pool must be no more than 120 feet

The inequality that represent this scenario is

$2x+44 \leq 120$

Solve for x

$2x \leq 120-44$

$2x \leq 76$

$x \leq 38\ ft$

therefore

The maximum width of the pool must be 38 ft

A would be (-3, 6).

B would be (-6, 3).

Anytime something is asking you to reflect off of the Y-axis, you put the original but flipped. Also, your answer will always be straight across vertically.

What greatest three digit number whose hundreds is two less than its ones digit

kodGreya [7K]

Answer:

799

Step-by-step explanation:

Let x = the hundreds digit

Let y = the ones digit

x = y-2

We want to maximize x and y. The both have to be single digit numbers

Rewriting this

x+2 =y

The largest x can be is 7 if y is a single digit

x is 7 and y is 9

We can pick the tens digit. Make it as big as possible to make out number as large as possible

The graph represents a distribution of data.

makvit [3.9K]

Answer:

Mean=50

Step-by-step explanation:

The mean of a probability distribution is a <u>measure of central tendency</u>,and gives information about how the possible values of x are distributed.

The vertical axis measures the probability of finding a specific value of x in the sample. The probability of finding a value near the mean is high (that is why the value of the function that is depicted in the vertical axis, increases as we get closer to the mean=50): this is because the mean is that value of x around which higher probability of occurrence is associated.

Select the functions that have identical graphs.

Elan Coil [88]

Answer:

c. 1 and 3

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot each equation.

Please see the attached image below, to find more information about the graph

The equations are:

1) y = sin (3x + π/6)

2) y = cos (3x - π/6)

3) y = cos (3x - π/3)

Looking at the graphs, we can see that the identical ones

are equations one and three

Correct option:

c. 1 and 3
