What is the equation of Parabola ?

The general equation of a parabola is

y = a(x-h)² + k

or

x = a(y-k)² +h

where (h,k) denotes the vertex.

It is given in the question that the value of h is doubled for the equation given

y = a(x-h)² + k

if the value of the h is doubled, the vertex of the graph shifts and shifts on the x axis away from the y axis , therefore

the vertex of the graph moves to a point twice as far from the y-axis.

Step-by-step explanation: I am not sure how I am supposed to draw a picture of the number other than drawing the number itself. However, 10 is an even number because it is a composite number and is divisible by 2. 10 is an even number, not an odd number. Hope this helps!

Argelis had þhe following containers of paint leftover, 1/2 gallon, 3/4 quarts and 1/4 gallon. How many quarts of paint does argelis have left

Answers

3.75 quarts of paint does Argelis have left with her.

What is Gallons?

A unit of volume for measuring liquids. 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces.

Here, we know that,

1 gallons = 4 quarts

so, 1/2 gallons = 1/2 X 4 = 2 quarts.

and 1/4 gallons = 1/4 X 4 = 1 quarts.

Now, total paint left with Argelis = 1/2 gallons + 3/4 quarts + 1/4 gallons

                                                     =  2 quarts + 3/4 quarts + 1 quarts

                                                    = 3 quarts + 3/4 quarts

                                                    = 15/4 quarts or 3.75 quarts

Thus, 3.75 quarts of paint does Argelis have left with her.

a house and lot cost $120,000. if the house cost 3 times more than the lot, how much did the house cost?

Answers

Answer:

$90,000

Step-by-step explanation:

We can can use substitution for this. First, we need to create two separate problems that represent this situation. The house and the lot together cost 120000, so we can make the equation h+l=120000. We also know that the house is worth 3 lots, so we can make the equation h=3l. Because h=3l, we can substitute for h, making the equation 3l+l=120000, or 4l=120000. To isolate l, we have to divide both sides by 4. If we do that, we get l=30000. Now, we have to substitute to find h. Our new equation is h+30000=120000. To isolate h, we have to subtract 30000 from each side. If we do this, we get h=90000. That's our answer.

Answer:

A. [tex]12x^{4} -4x^{3} +3x^{2} +3x+20[/tex]

Step-by-step explanation:

For this problem, we have to combine like terms.

Let's look at the equation:

[tex]12x^{4[/tex], [tex]-4x^{3}[/tex], [tex]3x^{2}[/tex] do not have any other like terms, so we keep all in the final answer.

[tex]7x[/tex] and [tex]-4x[/tex] are like terms, so we combine them. [tex]7x-4x=3x[/tex]

14 and 6 are like terms, so we combine them. 14+6 = 20

Let's put everything into the final equation:

Bailey went out to dinner. It cost $ 45.00. He wanted to leave a 20% tip for his waitress. Find the tip.​

Answers

Answer:

The tip should be $9.00

Step-by-step explanation:

We can start by making this more simple for ourselves.
A 10% tip is much easier to work with, rather than a 20% tip.
10% of 45 is 4.5. Since it’s a 20% tip, we’d multiply that by 2 to get 9.
Bailey should leave a $9 tip for the waitress.

Which newspaper is actually closest to the percentage of voters who support the governor reelection?

The sample size (n) is the total number of completed responses gathered from a survey sampling process.

From the given information, using the formula for standard error of a sample proportion:

71% of 1100 of the tribune = 0.0136867% of 900 of the herald = 0.0148381% of 700 of the times = 0.01567

Number of children = 100

When we subtract the total number of men and women from the total people 'x', we get the number of children.

[tex]\sf x - \left(\dfrac{1}{4}x+\dfrac{1}{3}x\right)= 100\\\\x - \left(\dfrac{1*3}{4*3}x+\dfrac{1*4}{3*4}x\right)=100\\\\[/tex]

A rectangle patio has a perimeter of 38 feet. If the length of the patio is 5 feet less than twice the width, find the dimensions of the patio

Answers

Answer:

The length is 11ft.

The width is 8ft.

Step-by-step explanation:

Hello!

Perimeter of a rectangle: [tex]P = 2(l + w)[/tex]

P = perimeterl = lengthw = width

We know that the length is 5 ft less than twice the width, which can be expressed by the equation: l = 2w - 5. We can plug in 38 for "P".

We can substitute the equation for l, and solve for the width.

Solve for W[tex]P = 2(l + w)[/tex][tex]38 = 2((2w - 5) + w)[/tex][tex]38 = 2(3w - 5)[/tex][tex]38 = 6w - 10[/tex][tex]48 = 6w[/tex][tex]8 = w[/tex]

The width is 8. We can solve for the length by plugging it back into the equation l = 2w - 5

Solve for Ll = 2w - 5l = 2(8) - 5l = 16 - 5l = 11

The length is 11.

The dimensions are 11 ft and 8 ft.

In a right triangle, the 58-cm hypotenuse makes a 51-degree angle with one of the legs. To the nearesttenth of a cm, how long is that leg?

Step-by-step explanation:

1kg ⇒ 1000g

So, a quarter kilogram means,

[tex]\frac{1}{4}[/tex] × 1kg = 1000g ×  [tex]\frac{1}{4}[/tex]

[tex]\frac{1}{4}[/tex] × 1kg = 250g

According to the question,

250g = R s. 60

So, now they're asking for the price of 150g.

Let that price be x.

250g ⇒ R s. 60

150g  ⇒ x

Use cross multiplication to find the value of x.

250x = 60 × 150

250x = 9000

Divide both sides by 250.
