Answer:

y-32=3(x-5)

Step-by-step explanation:

The swimming pool is being drained at a constant rate of 3 inches per hour, therefore:

If the depth of the water after 5 hours is 32 inches.

The depth is the dependent variable(as its values varies with time) while the time is the independent variable, we can write this as a pair (x,y)=(5, 32).

The point slope form of the equation of a line is of the form: [tex]y-y_1=m(x-x_1)\\(x_1,y_1)=(5,32), m=3\\$Substituting these values, we obtain:\\y-32=3(x-5)\\This is the equation of the function in point slope form.[/tex]

Find attached to this question, the diagram of the right angle triangle

Answer:

Leg a = 4

Step-by-step explanation:

A right angle triangle has 3 sides : side a, b and c

The formula to solved for a right angle triangle =

a² + b² = c²

In that above question,

a = unknown

b = 3

c = 5

Therefore,

a² + 3² = 5²

a² = 5² - 3²

a² = 25 - 9

a² = 16

a = √16

a = 4

Therefore, leg a = 4

Answer:

[tex] \frac{9c + 160}{5} [/tex]

Step-by-step explanation:

C = 5(F - 32)/9

so we do a little algebra here

9C = 5F - 160

we move both side

5F - 160 = 9C

5F = 9C + 160

so in the end

F =

[tex] \frac{9c + 160}{5} [/tex]

a = 9

b = 160

c = 5

Answer:

[tex]F=\frac{9C+160}{5}[/tex]

Step-by-step explanation:

[tex]C=\frac{5(F-32)}{9}[/tex]

Multiply both sides with 9.

[tex]9C=5(F-32)[/tex]

Use distributive property.

[tex]9C=5F-160[/tex]

Add 160 to both sides.

[tex]9C+160=5F[/tex]

Divide 5 to both sides.

[tex]\frac{9C+160}{5}=F[/tex]

Answer:5

Step-by-step explanation:

rate of change is the same thing as slope (or m)

The required rate of change for the given equation y = 5x + 25 is 5.

Given that,
For the given equation y =5x +25 the rate of change is to be determined.

The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,
The given equation,
y = 5x + 25
Differentiate the above equation with respect to x,
dy/dx = d(5x +25)/dx
dy/dx = 5dx/dx + d25/dx

dy/dx = 5      (since dx/dx =1 and d25/dx = 0)
here dy/dx is the slope of the equation or m or rate of change = 5

Thus, the required rate of change for the given equation y = 5x + 25 is 5.

x = [tex]-\frac{9}{2}[/tex]

Step-by-step explanation:

=> 3+2(2x+8) = 1

=> 3+4x+16 = 1

=> 4x+19 = 1

=> 4x = 1-19

=> 4x = -18

Dividing both sides by 4

=> x = [tex]-\frac{18}{4}[/tex]

=> x = [tex]-\frac{9}{2}[/tex]

Answer: -9/2

Step-by-step explanation:

3 + 2(2x + 8) = 1

3 + 4x + 16 = 1

19 + 4x = 1

4x = -18

x = -18/4 = -9/2

Answer:

C. (4,0)

Step-by-step explanation:

Given a graph of the system of equations

3x+4y=12; and

2x-y=8.

We can see that both lines pass through (4,0). Therefore, (4,0) is a point of intersection of the two lines.

It is therefore a solution to the system of equations.

Answer:

7/10

Step-by-step explanation:

Finding the totals of each column and row, we find:

There are 3+2+1 = 6 children in the baseball league.

There are 7+2+1 = 10 children in the softball league.

There are 3+7 = 10 children in the 7-9 division.

There are 2+2 = 4 children in the 10-12 division.

There are 1+1 = 2 children in the 13-15 division.

There are a total of 10+6 = 16 children.

We start with the information that the team is a member of the softball league.  There are 10 children in this league; this is the denominator of the probability.

There are 7 children in the 7-9 division that are in the softball league.  This gives us the probability 7/10.

Answer:(3x – 1) and (x + 4)

Step-by-step explanation:

Jenna needs to model the factors (3x – 1) and (x + 4) for the sides of the configuration. The correct answer would be an option (B).

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original.

The model is given in the question, as follows:

3x² + 11x – 4

Each row has a coefficient of 3 and an x term, which can be modeled with 3 tiles and 1 tile, respectively.

The first row has a constant term of -1, which can be modeled with 1 tile in the Factor 1 spot.

The second row has a constant term of 4, which can be modeled with 4 tiles in the Factor 2 spot.

So, the configuration shows the correct factors (3x – 1) and (x + 4) for the sides of the model.

Answer: 84 people

Step-by-step explanation:

From the question, 240 people are going to a charity event and 3/5 of the guests have ordered chicken for their meals. This means (3/5 × 240) = 144 people ordered chicken. Since 144 people have ordered, the number of remain people left will be:

= 240 - 144

= 96 people.

Out of the remaining guests which is 96, 12.5% have ordered gluten free meals. This means (12.5% × 96) = 12 ordered gluten free meals.

The people who haven't ordered their meals yet will be:

= 96 - 12

= 84 people.

Using the appropriate arithmetic operations, the number of guests who haven't made an order yet is 126

Chicken orders = 3/5 × 240 = 144

Number left = 240 - 144 = 96

Gluten free meat = 12.5% × 144 = 18

Not yet ordered = 144 - 18 = 126

Therefore, the Number of guests who haven't made an order yet is 126

Step-by-step explanation:

Proportion of students using the app, p = 63/100 = 0.63

Sample size, n = 2

Probability that the two students are using the app.

Radius of the circle is 15 inches.

Step-by-step explanation:

Relation between length of arc, radius and the angle subtended by the arc on center is:

[tex]\theta = \dfrac{l}{r} ..... (1)[/tex]

where [tex]\theta[/tex] is the central angle in radians subtended by arc

[tex]l[/tex] is the length of arc

[tex]r[/tex] is the radius of arc

We are Given the following details:

[tex]l = \dfrac{5\pi}{4}\ inch[/tex]

[tex]\theta = 15^\circ[/tex]

We know that [tex]\pi \ radians = 180 ^\circ[/tex]

Converting [tex]\theta[/tex] to radians:

[tex]\theta =\dfrac{\pi}{180} \times 15[/tex] radians

Putting the values of [tex]\theta[/tex] and [tex]l[/tex] to find the value of [tex]r[/tex]

[tex]\dfrac{\pi}{180} \times 15 = \dfrac{5\pi}{4r}\\\Rightarrow r = \dfrac{45}{3} \\\Rightarrow r = 15 \ inches[/tex]

The interval between which the sales of the Marcus were constant was (0, 5) to (5, 6) and (5, 6) to (6, 12)

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given, Marcus tracked the changes in his sales over a 12- month period.

we need to find at which interval was the change in Marcus's sales constant.

First we need to plot the graph, the points given to us will show us the sale of Marcus from the beginning to the end.

The rapid increment is  in the number of sales for that period of time is  (0, 4) and (0, 5) as we can see a straight line.

Line between point (0, 5) and (5, 6), there is a slant line therefore, which shows that were slow and constant growth in the sale of Marcus as the line is increasing upwards.

The line between the points (5, 6) and (6, 12) is also a slant line but the slope of the line is high than the previous line for points  (0, 5) and (5, 6).

Constant growth between these two points and this growth was also constant but it was more rapid as compared to sales between the point (0, 5) and (5, 6).

Therefore the interval between which the sales of the Marcus were constant was (0, 5) to (5, 6) and (5, 6) to (6, 12)

Answer:

D

Step-by-step explanation:

A function of x means that there can only be one value of y per x value.  Therefore, D does not match this because there are 4 values of y per x value (3).

Answer:

D

Step-by-step explanation:

Each x value can have only ONE y value

this means that there cannot be more than one of the same x value:

think of the x values as an input, each input has one output right?

ex:

input: 7

output:8

input:3

output:2

how is it possible that the same input has different outputs?

input: 5

output: 6,7

this does not make any sense, one input should only have one output hence, one value of x(input) should have only one value of y(output)

Hope this helps!
