What is the equation of the parabola with vertex (6,7) and focus (7,7)?

Mathematics

Answer:

Step-by-step explanation:

If you plot these points on a coordinate plane, you see that they are on the same horizontal line, y = 7, with the focus 1 unit to the right of the vertex.  This means that the parabola is a sideways opening parabola, to the right, to be more specific.  That means that it has the basic vertex form

4p(x-h)=(y-k)^2

where p is the distance in units from the vertex to the focus, h is the first coordinate in the vertex, and k is the second coordinate in the vertex.  For us, p = 1, h = 6, and k = 7.  Now we will just fill the vertex form of the equation in with our values:

4(x-6)=(y-7)^2

We will solve this for x now by dividing each side by 4 and adding over the 6:

x=\frac{1}{4}(y-7)^2+6

Help I don't know how to do this<br>​
Vilka [71]

Answer:

P(t) = 282.2(1.009)^t

Step-by-step explanation:

Look at the attached image.

Hope you can read my handwriting. the image cut off the right side, b = 1.009213324... but question asks to round to nearest thousandth so it's 1.009

For the second part just use the equation to find P when t = -1 and see if P is less than (underpredicts) the number from the question or greater than (overpredicts) the number. I haven't calculated it but I think it will be smaller and thus underpredicts just from looking at the numbers when t = -1

The number of comic books is an illustration of a linear function

  • The complete equations are: \mathbf{8b + 17 =65} and \mathbf{b =6}
  • The value of b has increased by 4

She had 17 comic books already.

So, we have:

\mathbf{Base\ Amount = 17}

Her order of 65 books contains 8 comic books per collection.

So, we have:

\mathbf{Rate = 8}

\mathbf{Total = 65}

This is represented as:

\mathbf{Rate \times b + Base\ Amount =Total}

So, we have:

\mathbf{8\times b + 17 =65}

Rewrite as:

\mathbf{8b + 17 =65}

Subtract 17 from both sides

\mathbf{8b =48}

Divide both sides by 8

\mathbf{b =6}

Assume she has 97 books in her collection, then the equation would be represented as:

\mathbf{8b + 17 = 97}

Subtract 17 from both sides

\mathbf{8b  = 80}

Divide both sides by 8

\mathbf{b  = 10}

The values of b are 6 and 10.

The difference between 6 and 10 is 4

Hence, the value of b has increased by 4

What us 2/3 divided by 6?
iren [92.7K]

Answer:

0.111111111 or 1/9

Step-by-step explanation:

2/3 divided by 6

keep change flip = KCF

Keep the 2/3

Flip the sign into the opposite

Change the 6 to it's reciprocal

2/3 times 1/6

multiply both the numerator, and denominator

2*1= 2 ( numerator)

3*6= 18 ( denominator)

2/18 simplify that and you get..........

1/9 as your answer

Hope this helped!

0.2 ( 10 - 5c ) = 5c - 16
Mumz [18]

Answer: c = 3

Step-by-step explanation: Distribute 0.2 to (10-5c)

2-1c=5c-16

Then subtract 2 on both sides and subtract the 5c.

-1c=5c-18

-6c=-18

Then divide -6 to -18

-18/-6 = 3
