if reflected over x-axis, then use the formula: (x,y) → (x, -y)

  • new coordinates: (5, 6)

then if translated -5 horizontally, there will be change in x axis

  • new coordinates: (5-5, 6) → (0, 6)

Jackson has to repaint some bookcases He has 2 gallons of bank all of the bookcases are the same size and requires 2/5 gallon of
Vesnalui [34]

Complete question is;

Jackson has to repaint some classroom bookcases. He has 2 gallons of paint. All the bookcases are the same size and each requires 2/5 gallon of paint. How many bookcases is he able to repaint with the amount of paint?

Answer:

5 books

Step-by-step explanation:

Jackson has 2 gallons of paint

Now, for us to find the number of bookcases the Jackson will be able to repaint if each bookcase requires 2/5 gallon, we will just divide 2 by 2/5

Thus;

Number of book cases Jackson will be able to repaint = 2 ÷ 2/5

Thus gives; 2 × 5/2 = 5 books

Find the range of the quadratic function. (y=2x^2-20x+53)
Anit [1.1K]

Answer: The range is y ≥ 3.

Step-by-step explanation:

When we have an equation:

y = f(x)

The range is the set of the possible values of y.

In this case, we have:

y = f(x) = 2*x^2 - 20*x + 53

This is a quadratic equation, and the leading coefficient is positive. This means that the arms of the graph will open upwards.

Then the minimum value of y will be the vale at the vertex.

We know that for a quadratic equation of the form:

a*x^2 + b*x + c

The vertex is at:

x = -b/2a

Then in this case, the vertex will be at:

x = -(-20)/(2*2) = 20/4 = 5

Then the smallest value of this function will be:

f(5) = 2*5^2 - 20*5 + 53 = 3

This is the smallest value that y can take, and y can take any value greater than 3.

Then the range can be written as:

y ≥ 3.

The answer is 1575 but I need to show my work! (find the total volume)
kirza4 [7]

Answer: 1575

Step-by-step explanation:

Volume of Pyramid: b*l*h/2 = 21*9*7/3 = 441

Volume of Rectangular prism = V= lwh = (21*12*9)/2 = 1134 (divide by two because it is half of a rectangular prism)

441 + 1134 = 1575

Arithmetic of Functions problem<br> Open ended
VladimirAG [237]

Answer: <em>(gºh)(25)=2</em>


Step-by-step explanation:

1. This exercise is about Composition of functions, then you have:

2. Then, you have that

<em>(gºh)(25)</em>=g(h(x))=\sqrt{x}-3

3. Now, you must substitute 25 into the function, as you can see below:

<em>(gºh)(25)</em>=\sqrt{25}-3

4. Simplify the fucntion.

5. Therfore, you obtain:

<em>(gºh)(25)</em>=5-3=2
