The difference in the salary Cynthia will earn working as a camp counselor instead of a lifeguard after x hours (f − g)x = 5x - 25.

A function can be defined as the set of inputs that results in output.

Given, Cynthia earns 20 dollars per hour working as a camp counselor plus an additional 25 dollars as a bonus which is f(x) = 20x + 25, and as a lifeguard 15dollars per hour and an additional 50 dollars bonus which is g(x) = 15x = 50.

We know (f - g)x = f(x) - g(x).

∴  The difference in the salary Cynthia will earn working as a camp counselor instead of a lifeguard after x hours is f(x) - g(x).

=  (20x + 25) - (15x + 50).

= 20x - 15x + 25 - 50.

= 5x - 25.

f is the given profit function whose input is number of cones and output is profit, f(50)=80 tells that $80 profit is made by selling 50 cones of ice cream.

A function is a relation that assigns each element of a set a unique element of another set.

f(x) denotes that function f works on the input values x and give output f(x).

If f is a function and f(x) = x+2, then if we have to check x= 1 , then

f(1) = 1+2 = 3 is the value of the function f at x=1

A La Mode Ice Cream Parlor uses a function f as profit function

The input x is the number of cones it sells and output is profit

f(50) = 85

⇒x = 50 and f(50) = 85

It means that when the parlor sells x = 50 cones , it makes  profit $ f(50) = 85

or On selling 50 cones the profit made is $80

Assume that the given statements are

(a) c(0)=0

(b) c(3)=c(8)

(c) c(n)=29

(d) c(13)<c(12)

Let c(t) be the number of customers in a restaurant t hours after 8 A.M.

We need to find the meaning of each given statement.

(a) c(0)=0 means the number of customers 0 hours after 8 A.M (i.e., 8 A.M.) is 0.

(b) c(3)=c(8) means the number of customers 3 hours after 8 A.M (i.e., 11 A.M.) is equal to the number of customers 8 hours after 8 A.M (i.e., 4 P.M.).

(c) c(n)=29 means the number of customers n hours after 8 A.M is 29.

(d) c(13)<c(12) means the number of customers 13 hours after 8 A.M (i.e., 9 P.M.) is less than the number of customers 12 hours after 8 A.M (i.e., 8 P.M.)

The function operation ( f + g )( x ) in the functions f( x ) = x² + 2x and g( x ) = 4x² - 3 is 5x² + 2x  - 3.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

First, replace the function designators in f + g with actual functions.

( f + g )( x ) = ( f )(x) + ( g )( x )

( f + g )( x ) = ( x² + 2x ) + ( 4x² - 3 )

Remove the parenthesis

( f + g )( x ) = x² + 2x + 4x² - 3

Collect and add like terms

( f + g )( x ) = x² + 4x² + 2x  - 3

( f + g )( x ) = 5x² + 2x  - 3

Therefore, the function operation ( f + g )( x ) is 5x² + 2x  - 3.

For

To solve for x you have to multiply both sides of the expression by 20

b)

Following the same logic, the ratio between x and 20 is the same as the ratio between 6 and 8

6/8 can be simplifies as 3/4. Then multiply both sides by 20 to determine the value of x.

As mentioned above, when two triangles are similar, the corresponding sides are always in the same ratio, that is why the results in a and b are the same.

A graph of the linear function (y = 2x - 3) which matches the answer is shown in the image attached below.

A graph refers a type of chart that's commonly used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

Generally speaking, the graph of any proportional relationship such as a linear function is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-axis decreases or increases, the values on the y-axis decreases or increases simultaneously as shown in the image attached below.

In conclusion, a graph representing the given linear function shows a proportional relationship between the value of x and y.

Answer:

<3 and <4 are complementary

The slope between the two pair of points is 3/2. Yes, Dan's productivity is constant.

Number of model are represented on y axis and the hours are represent on x axis.

As we can observe,

One pair of points on the graph is (4,6) and (2,3) and the other pair of points is (6,9) and (0,0)

The slope m between any two points (a,b) and (c,d) can be calculated as,

m = (d-b)/(c-a)

The two points we have are (4,6) and (2,3), so the slope M between them is,

M = (3-6)/(2-4)

M = -3/-2

M = 3/2.

And the slope M' between other two point (6,9) and (0,0) is,

M' = (9-0)/(6-0)

M' = 9/6

M' = 3/2.

As we can see, the slope is same. The slope represents the ratio of number of models and hours. We can conclude that Dan's productivity is constant.

Hope the picture will help you.......

The size of the angle x in the pentagon is 36 degrees.

A regular pentagon is a polygon with five sides. The angles of a regular polygon is equal to each other.

Therefore,

the sum of angles in a regular pentagon = 540 degrees.

Each angle in a regular pentagon is 540 / 5 = 108 degrees.

The rhombus is inside the pentagon. Opposite angles in a rhombus are equal.

Therefore, the sum of interior angles of a rhombus adds up to 360 degrees

Hence,

108 + 108 + 2y  = 360

where

y is the angle of the rhombus on the x variable.

Therefore,

2y = 360 - 216

2y = 144

y = 144 / 2

y = 72°

Therefore,

x = 108 - 72

The vertex and the range of the absolute value function are given as follows:

(−2, −3); −3 ≤ y < ∞.

The absolute value function in the context of this problem is defined according to the following rule:

y = |x + 2| − 3.

For the general equation, with vertex (h,k), the definition is given as follows:

y = |x - h| + k.

Hence, in the context of this problem, the coefficients of the vertex are given as follows:

h = -2, k = -3.

Hence the vertex is:

(-2,-3).

The range of a function is the set containing all the output values assumed by the function. For the absolute value function, it is given by the following interval:

Answer:

The first questions unknown equals

[tex] \frac{3025}{49} [/tex]

The second question is unclear. I assume it is to simplify if that is the case the answer will be.

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

First Question I made ?=x for simplicity.

[tex]7 \sqrt{x} = 55[/tex]

then I divide both sides by 7

[tex] \sqrt{x} = \frac{55}{7} [/tex]

then I square both sides

[tex]x = \frac{3025}{49} [/tex]

Question 2

I simplified by dividing both the denominator and the numerator by their HCF (highest common factor) which is 5

[tex] \frac{5 \div 5}{10 \div 5} [/tex]

which equals

[tex] \frac{1}{2} [/tex]

Answer:

[tex]\textsf{1.} \quad 7\sqrt{\dfrac{3025}{49}}=55[/tex]

[tex]\textsf{2.} \quad \dfrac{5}{10}=\dfrac{1}{2}[/tex]

Step-by-step explanation:

Let x be the unknown number:

[tex]\implies 7\sqrt{x}=55[/tex]

Divide both sides of the equation by 7:

[tex]\implies \dfrac{7 \sqrt{x}}{7}=\dfrac{55}{7}[/tex]

[tex]\implies \sqrt{x}=\dfrac{55}{7}[/tex]

Square both sides of the equation:

[tex]\implies \left(\sqrt{x}\right)^2=\left(\dfrac{55}{7}\right)^2[/tex]

[tex]\implies x=\dfrac{55^2}{7^2}[/tex]

[tex]\implies x=\dfrac{3025}{49}[/tex]

Divide the numerator and the denominator by the highest common factor:

[tex]\implies \dfrac{5 \div 5}{10 \div 5}=\dfrac{1}{2}[/tex]

The general slope intercept form equation of a line is as stated below;

where m is the slope and b is the intercept.

If we compare the given equation y = 5x-1 with the equation of a line, we can deduce that the slope, m, is 5.

The slope of a line perpendicular to another is always given as -1/m, therefore the line perpendicular to the line y=5x-1 will have a slope of -1/5;

So let's go ahead and substitute m= -1/5, into the point slope equation to determine the line that passes through (-5,7);

Remember, the point slope form equation of a line is given as;

Substituting the above values, we'll have

Let's open up the parenthesis first, we'll have;

Let's isolate y by adding 7 to both sides of the equation;

The above equation is the required equation of the line in slope intercept form which can be compared to the one earlier written above(y = mx + b).
