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.

Answer:

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]

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.

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)

r = 8

Step-by-step explanation:

→Distribute the 7 to (-3r + 16):

-16r + 15 + 17 = 7(-3r + 16) - 5r

-16r + 15 + 17 = -21r + 112 - 5r

→Add like terms:

-16r + 32 = -26r + 112

→Add 26r to both sides:

10r + 32 = 112

→Subtract 32 from both sides:

10r = 80

→Divide both sides by 10:

r = 8

Answer:

Step-by-step explanation:

-16r +15+17= 7(-3r+16)-5r

-16r+32 = -21r +112-5r

-16r +26r=112-32

Comment on "standard form"

In the US, a number is in standard form if it is written as a sequence of decimal digits and a decimal point (if there is a fractional part), usually with no leading zeros (left of the decimal point). The sign is prepended to that digit string, as shown above.

In the UK, a number is in standard form if it is written in "scientific notation." The rule for writing a number in standard form is that first you write down a number between 1 and 10, then you write ×10(to the power of an integer). Usually powers of 0, or multipliers of 1, are not written. Then the number here is still -4.2, rather than -4.2×10⁰.

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]

Answer:

Area of the rectangle A = 17 units²

Step-by-step explanation:

Area of the rectangle A = Area of rectangle ACEG - (Area of the triangle ABH + Area of triangle BCD + Area of triangle DEF + Area of the triangle FGH )

Area of rectangle ACEG = Length × Width

                                        = (5 units) × (5 units)

                                        = 25 square units

Area of the triangle ABH = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                         = [tex]\frac{1}{2}(4)(1)[/tex]

                                         = 2 units²

Area of the triangle BCD = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                         = [tex]\frac{1}{2}(1)(4)[/tex]

                                         = 2 units²

Similarly, area of the triangle DEF = 2 units²

And area of the triangle FGH = 2 units²

Now area of the rectangle A = 25 - (2 + 2 + 2 + 2)

                                                = 25 - 8

                                                = 17 square units

Therefore, area of the rectangle A = 17 square units

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.
