O C. It is a one-to-one function.
O D. It is a many-to-one function.

pls help!!

Answers

Answer 1

Answer:

D. It is a many-to-one function

Step-by-step explanation:

One-to-one if every y value has exactly one x value mapped onto itMany-to-one if there are y values that have more than one x value mapped onto them.

We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function

Correct option is D

A department store buys 100 shirts at a cost of $2,400 and sells them at a selling price of $30 each.
Find the percent markup.

Answers

Answer:

There is a 25% markup

Step-by-step explanation:

First find the original cost of each shirt

$2400/ 100 shirts

$24/ shirt

Mark up = ( new price - original price) / original price

= ( 30-24) / 24

= 6/24

= 1/4

= .25

25%

There is a 25% markup

Answer:

percent markup = 25%

Step-by-step explanation:

buys 100 shirts = $2400

buys 1 shirt = $2400/ 100

= $24

sells 1 shirt = $30

percent markup:

=[ ( selling price - bought price) ÷ bought price ] × 100

= [ (30-24) ÷ 24 ] × 100

= [ 6 ÷ 24 ] × 100

= 0.25 × 100

= 25 %

Johanna took $125 to the mall. She bought 5 shirts (s) that cost the same price. Which expression represents the amount of money, in dollars, that Johanna had after she bought the shirts?

Answers

Answer:

I think its something like: Money Leftover = 125 - (price of one shirt * 5)

Step-by-step explanation:

just use variables in the place of "price of one shirt" and "Money Leftover".

multiplying the price of one shirt by five since she buys 5 of the same shirt and subtracting that value from her budget will leave you with the amount of money she had left after the purchase.

Answer:

125-5s=money left over (s is the price of one shirt)

Answer:

D. R = {-7, 1, 9, 17}

Step-by-step explanation:

Substitute the given values for x to see what the y-values are.

f(x) = 4x +9

f({-4, -2, 0, 2}) = 4{-4, -2, 0, 2} +9 = {-16, -8, 0, 8} +9

= {-7, 1, 9, 17} . . . . . matches choice D

Step-by-step explanation:

D. R = {-7, 1, 9, 17}

A self-service car wash has 3 individual car wash stalls. Customers wait in a single line before choosing the next available stall. 33 customers enter the car wash per hour and it take 5 minutes for each customer to wash their car. Customer arrivals and service times follow an exponential distribution. What type of queuing model is this process?

Answers

Answer:

single-channel, multi -phase

Step-by-step explanation:

The concept known as '' Queuing'' is not only important in the mathematical aspect alone but it is also useful in economic matters as signifies the abundance of resources that is when we have queues it means the reason for it is that the available resources is not enough.

From the question above we have that there are 3 individual car wash stalls, it is also given that the customers wait in a single line before choosing the next available stall. This means that there is only a single-channel.

Then, we have that from the single line initially, the queues then moves to multi -phase that is to 3 individual car wash stalls.

Step-by-step explanation:

F(x) = 3x + 1

Inverse:

x = 3y + 1

3y = x - 1

y = x/3 - 1/3 or f^ - 1 (x) = x/3 - 1/3

f^ - 1 (x) = x/3 + 1/3 is not the inverse function of f(x) = 3x + 1

A password hash function is applied 12 times to secure a password. If it takes 21 minutes to brute force one application of the hash with the available resources, how long will it take to brute force the password if the available resources are quadrupled.?

a. 21 minutes
b. 63 minutes
c. 210 minutes
d. none of the above.

Answers

Answer:

b. 63 minutes

Step-by-step explanation:

Given;

number of times the hash function is applied = 12

time taken to brute force one application, = 21 minutes

Apply proportion, bearing in mind that 4 available resources should take less time;

1 available resource ------- 21 minutes

4 available resources ------ x

Thus, x = 21 minutes / 4

When applied 12 times, the time should be [tex]\frac{21 \ minutes}{4} \ \times \ 12 \ = 63 \ minutes \\\\[/tex]

Therefore, the correct option is B, 63 minutes

Answer:

-7/4 < x < 8

Step-by-step explanation:

The value of y can be determined from the sum of the angles, so you know each of the angles exactly. That means you know the ratio of side lengths exactly, which lets you solve for x exactly.

Setting that aside, we observe that angle C is greater than angle A, so side AB will be longer than side BC.

3x +15 > 4x +7

8 > x . . . . . . . . . . subtract 3x+7

We also know that the lengths of these sides must be positive. Since BC is the shorter side, we require ...

4x +7 > 0

4x > -7

x > -7/4

So, the allowable values of x are ...

-7/4 < x < 8

_____

More complete solution

If we read the figure correctly, the sum of angles is ...

(2y +12) +(4y +12) +(y -18) = 180

7y +6 = 180

y = (180 -6)/7 = 24 6/7°

Then (in degrees) ...

∠A = 2(24 6/7) +12 = 61 5/7, and ∠C = 4(24 6/7) +12 = 111 3/7

The Law of Sines tells us ...

AB/sin(C) = BC/sin(A)

sin(A)(3x +15) = sin(C)(4x+7)

x(4sin(C) -3sin(A)) = 15sin(A) -7sin(C)

x = (15sin(A) -7sin(C))/(4sin(C) -3sin(A))

x ≈ 6.1872652

A cellphone company charges a monthly rate of $55 for unlimited text and data and $0.50 per minute for phone calls. The bill for last month was $66. Write and solve an equation to find out how many minutes for phone calls were charged on this bill.

Answers

y=0.50x-55
So 0=0.50x-55
Add 55 from both sides
55=0.50x
Divide 0.50 on both sides
55 /0.50 = 110
I could be wrong so yup

55 + 0.50m = 66M= Mins

Solve- 55+0.50m = 66

-55 -55

0.50m = 11

50. B51. -3x + y = 11

Step-by-step explanation:

50......................................................................

Parallel lines have equal slopes.

Converting the given into slope-intercept form:

2x + 3y = 153y = -2x + 15y = -2/3x + 5

Option B is the parallel line with different y-intercept

51.......................................................................

Perpendicular lines have negative reciprocal slopes.

Converting the given into slope-intercept form:

x + 3y = 153y = -x + 15y = -1/3x + 5

Perpendicular line will have a slope of

m*(-1/3) = - 1 m = 3

The equation will be:

y = 3x + b

to find b using the given point (-2. 5)

5 = 3*(-2) + b5 = -6 + b5 + 6 = bb = 11

So the line is:

y = 3x + 11

-3x + y = 11 in standard form

Answers

Answer:

The price of the burrito is $3.5 and the price of the taco is $2.5.

Step-by-step explanation:

2x+5y=19.5

5x+2y=22.5

------------------

5(2x+5y)=5(19.5)

-2(5x+2y)=-2(22.5)

-----------------------------

10x+25y=97.5

-10x-4y=-45

-----------------------

21y=52.5

y=52.5/21=2.5

2x+5(2.5)=19.5

2x+12.5=19.5

2x=19.5-12.5

2x=7

x=7/2=3.5

x=3.5, y=2.5

The price of the burrito is $3.5 and the price of the taco is $2.5.
