I f Bill wants to maximize his utility while spending $31 on apple. Bill van buy 10 whole pounds of Apples

given data

Apples cost $3 per pound

Bananas cost $5 per pound

amount Bill has to spend $31

The number of whole apple Bill can buy

Using $31 the number of whole apples this can buy is gotten  dividing the  the total amount by the price of apple per pound.

= amount Bill has to spend $31 / Apples cost $3 per pound

= 31 / 3

= 10.33

Since we are solving for whole pounds of apple Bill can buy 10 whole pounds of apples

= 27 workers

It should be noted that combination will be used to choose the 4 workers. This is illustrated as

Combination formula

ⁿCr = n! / ((n – r)! r!)

n = the number of items.

r = how many items are taken at a time.

where n = 33

r = 4

Step-by-step explanation: 105 divided by 3 is 35 there are 3 groups so 1 ten would go in each group.

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.

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 meaning of each statement is shown below.

Step-by-step explanation:

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 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).

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

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.

The average rate of change of the function f( x ) = x² + 7x + 6 at the interval of −4 ≤ x ≤ −1 is 2

The average rate of change the function is simply the change in y-values of the two points divided by the change in x-values of the two points.

It is expressed as;

Given the data in the question;

Average rate of change = ( f(-1) - f(-4) ) / ( (-1) - (-4) )

Average rate of change = ( (-1)² + 7(-1) + 6 ) - ( (-4)² + 7(-4) + 6 ) ) / ( (-1) - (-4) )

Average rate of change = ( (1 + -7 + 6 ) - ( 16 - 28 + 6 ) ) / (-1 + 4 )

Average rate of change = ( ( 0 ) - ( -6 ) ) / (-1 + 4 )

Average rate of change = ( 0 + 6 ) / ( 3 )

Average rate of change = 6 / 3

Average rate of change = 2

The measure of <5 is 47

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline.

The fundamental characteristics listed below make it simple to recognise parallel lines.

m<4=5x-42

and m<5=-x+82

as, <4 and <5 are in co- interior angle

<4 + <5 = 180

5x - 42 + (-x + 82) = 180

5x -42 - x + 82= 180

4x +40 = 180
