Write the quadratic equation in Vertex form with vertex (4 8) and passing through the origin.
Vertex = (4,8)
Passing through the origin = (0,0)
Vertex form:
y= a (x-h)^2+k
(h,k) is the vertex:
y= a (x-4)^2+8
Replace the (x,y ) by the origin coordinates
Solve for a
0= a (0-4)^2+8
-8 = a(-4)^2
-8 = a 16
-8/16 = a
-1/2 = a
y=-1/2 (x-4)^2+8
a basketball court is 94 ft long and 50 ft wide Ryan used long steps to estimate the length of the Court as 93 ft and a width as 48 what is the percent error of Ryan's measure area round to your nearest hundred
5.02%
Explanation:Percentage error formula = |(approximate value - Exact value)|/(exact value) × 100
Area of the court = length × width
length = 94 ft
width = 50 ft
Exact area = 94ft × 50 ft
Exact area = 4700 ft²

solve for y and simplify your answer5/4y = -9
what is the slope and y-intercept of negative 3x + 5y equals -15
-3x + 5y = -15
The general form of a line using slope and y intercept is: y = mx + b
where m is the slope and b is the y intercept
So we have to write the original equation in this form:
-3x + 5y = -15
5y = 3x - 15
y = (3/5)x - 15/5
y = (3/5)x - 3
In this case, m= 3/5 and b = -3
Therefore m = 3/5
Therefore the y intercept (when x = 0) is -3
Answer:
slope is 3/5
y intercept -3

Yolanda is preparing a liquid fertilizer that she will use on her lawn. She mixes 4 tablespoons of liquid fertilizer with 6 gallons of water.Using this ratio, how many gallons of water should be mixed with each tablespoon of liquid fertilizer?
Given data:
The given amount of liquid fertilizer is f=4.
The given water is w=6 gallons.
4 tablespoons= 6 gallons of water
1 tablespoon= 1.5 gallons of water.
Thus, 1.5 gallons of water is mix with each tablespoon.
Joshua is going to invest $9,000 and leave it in an account for 5 years. Assuming theinterest is compounded continuously, what interest rate, to the nearest tenth of apercent, would be required in order for Joshua to end up with $12,500?
Let r be the percent annual interest rate of the account. Since $9000 are left for 5 years, for an outcome of $12,500, then:
[tex]9000\times(1+\frac{r}{100})^5=12,500[/tex]Divide both sides by 9000:
[tex](1+\frac{r}{100})^5=\frac{12500}{9000}=\frac{25}{18}[/tex]Take the 5th root to both sides:
[tex]\begin{gathered} 1+\frac{r}{100}=\sqrt[5]{\frac{25}{18}} \\ \Rightarrow\frac{r}{100}=\sqrt[5]{\frac{25}{18}}-1 \\ \Rightarrow r=100(\sqrt[5]{\frac{25}{18}}-1) \end{gathered}[/tex]Use a calculator to find the decimal expression for r:
[tex]r=6.790716585\ldots[/tex]Therefore, to the nearest tenth:
[tex]r=6.8[/tex]This means that Joshua would need to invest his money on a 6.8% annual interest account.
1 point It takes 500 packing peanuts to fill a box that is 3 inches x 4 inches x 5 inches. How many peanuts would it take to fill a box that is 6 inches x 8 inches x 10 inches? 1,000 packing peanuts 2,000 packing peanuts 4,000 packing peanuts 8,000 packing peanuts
Well, this is a volume and ratio problem. In a box the volume is given by width times length times height, so the volume of the first box is 3*4*5=60 cubic inches.
In the second box, the volume is 6*8*10=480 cubic inches.
[tex]\frac{480}{60}=\frac{8}{1}=8[/tex]This means that in the big box you could place 8 peanuts for every peanut placed in the small box. If you need 500 peanuts to fill the small box, then for the big box:

3 Step Problem: Erik is building a cubby bookshelf, that is, a bookshelf divided into storage holes (cubbies) instead of shelves. He wants the height of the bookshelf to be x^2 - 2x - 3 and the width to be x^2 + 4x + 3. Each cubby hole in the bookshelf will have a height of x + 3 and width of x - 3.STEP 1 of 3: Write a rational expression to determine how many cubbies high the book shelf will be.
Step 1:
In order to determine the number of cubbies high, we just need to divide the total height x² - 2x - 3 by the height of one cubby x + 3:
x² divided by x: x
x multiplied by (x + 3): x² + 3x
x² - 2x - 3 minus x² + 3x: -5x - 3
-5x divided by x: -5
-5 multiplied by (x + 3): -5x - 15
-5x - 3 minus -5x - 15: 12
The division doesn't have remainder 0, so let's write the division as a fraction:

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal
[tex]\begin{gathered} 1993^0-360^0=1633^0 \\ 1633^0-360^0=1273^0 \\ 1273^0-360^0=913^0 \\ 913^0-360^0=553^0 \\ 553^0-360^0=193^0 \end{gathered}[/tex]Hence, the angle that coterminal with 1993 degrees is 193⁰

DEF~△VXW.244FED122WXVWhat is the similarity ratio of △DEF to △VXW?Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
We are given two triangles. We notice that each corresponding angle is equal, therefore, by Angle Angle Angle (AAA) theorem the triangles are similar. This means that each corresponding side is at the same ratio. That ratio is called the similarity ratio and it is obtained by finding the quotient between any two corresponding sides, like this:
[tex]r=\frac{DF}{VW}=\frac{DE}{VX}=\frac{FE}{WX}[/tex]Where "r" is the similarity ratio. Now, we substitute the sides:
[tex]r=\frac{4}{2}=\frac{4}{2}=\frac{2}{1}=2[/tex]Therefore, the similarity ratio is 2.

Answer : The linear function of the graph when move down 3 units is y = x - 3
The graph shift vertically because it is down 3 units
The standard equation of a linear function is
y = mx + b
Where b = intercept and m = slope
Move 3 unit down means b = -3
Hence, y = x-3
Answer is y = x - 3

What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The expression is,
⇒ (x² - 3x - 5) / (x² + 2x - 8) - (x² - 3x - 5) / (x² + 2x - 8)
Now,
Subtract the expression as;
The expression is,

⇒ (x² - x + 3) - (x² - 3x - 5) / (x² + 2x - 8)
⇒ x² - x + 3 - x² + 3x + 5 / (x² + 2x - 8)
⇒ 2x + 8 / (x² + (4-2)x - 8)
⇒ 2x + 8 / (x² + 4x - 2x - 8)
⇒ 2x + 8 / (x (x + 4) - 2 (x + 4))
⇒ 2(x + 4) / (x + 4) (x- 2)
