Answer:

-14

Step-by-step explanation:

\sqrt{16} = 4\\\\(\sqrt{16} - 1) = (4 -1) =3\\\\(3-9) = (-6)\\\\(3-9) ^2 = (-6)^2 = 36\\\\25 -  3 - 36 = 25 - 39 =  -14\\

You work for a rental car company. If customers return a car with under half a tank of gas, they are charged $7.50 per gallon of
expeople1 [14]

Answer:

<u>The correct answer is C. $ 39.89</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the questions correctly:

Tank capacity = 21 gallons

Cost of gallon of gas when the car is returned with under half a tank = $ 7.50

Cost of gallon of gas when the car is returned with more than half a tank = $ 5.75

Gas in the tank of the rental car = 1,800 fluid ounces

2. How much should you charge the customer to fill the tank?

Let's recall that 1 gallon = 128 fluid ounces

Now, we will answer the question this way, converting the tank capacity from gallons to fluid ounces:

Capacity of the gas tank = 21 * 128 = 2,688 fluid ounces

Like 1,800 is above the 50% of the tank, we will charge $ 5.75 per gallon to fill up the tank

Now, we calculate the cost of gas per fluid ounce, this way:

Cost per fluid ounce = 5.75/128 = $ 0.04492

Finally, we calculate how many fluid ounces the customer has to pay this way:

We will charge the customer = (2,688 - 1,800) * 0.04492

We will charge the customer = $ 39.89

<u>The correct answer is C. $ 39.89</u>

PLEASE HELP ME WITH THIS MATH QUESTION PLEASE FILL ALL BLANKS
maxonik [38]

Answer:

  1. 1/3
  2. y-axis
  3. (1, -2)

Step-by-step explanation:

The length AC is 3, but the corresponding length FD is 1, so the dilation factor is FD/AC = 1/3.

The reflection is a left/right reflection, so it is across a vertical line. We suspect the only vertical line you are interested in is the y-axis. (It could be reflected across x=1/2, and then the only translation would be downward.)

The above transformations will put C' at (1, 0). Since the corresponding point D is at (2, -2), we know it is C' is translated by (1, -2) to get to D.

  C' + translation = D

  (1, 0) +(1, -2) = (2, -2)

(Q2) Which of the following points lies on the graph of the function y = 4x ?
stepladder [879]

Answer:

C

Step-by-step explanation:

I think I will answer the question the your attachment because it has full information.

The function is: y = 3*2^{x}

a. The function decreases

Wrong, because the base number is 2 and it is greater than 0. The function will go up

b. y=intercept of  (0.2)

Wrong, Let substitute x =2 into the function: y = 3*2^{2} = 12  

c. if x increase by 1, the value of y will double

Because the base number is 2. For example:

  • If x = 2, y = 3*2^{2}  = 12
  • If x =3, y =3*2^{3} =(3*2^{2}*)2  = 24

d. contains the point (2,4)

Wrong, Let substitute x =4 into the function: y = 3*2^{4} = 48

So we choose C

the graph of a linear function is given below. What is the zero of the function? a) -5. b) 2/5. c) 2. d) 5/2
Murrr4er [49]

The zero of a function is the x-value at which the function value is zero. That is, the value of the function that intersects the x-axis. From the picture, the zero is -5
