Answer:

Vertex form is

a(x - h) {}^{2}  + k = y

where (h,k) is the vertex

So our vertex form is

a(x - 3) {}^{2}  + 5 = y

It passes through (6,0) so we have

a(6 - 3) {}^{2}  + 5 = 0

Solve for a.

a(3) {}^{2}  + 5 = 0

a(9) =  - 5

a =  \frac{ - 5}{9}

So our equation is

-  \frac{5}{9} (x - 3) {}^{2}  + 5

Teagan is dividing 6 by 11. If she continues the process, what will keep repeating in the quotient?
USPshnik [31]

Answer:

54 will keep repeating in the quotient.

Step-by-step explanation:

Quotient is defined as the answer we get after dividing a number by another number. For instance 10 / 2 = 5. Here 10 is dividend, 2 is the divisor and 5 is the quotient.

In this case 6 divide by 11 will give 0.54545454545....

54 keep repeating in the quotient.

How do I calculate this? Is there a formula?

<u>Answer:</u>

Height of cables = 23.75 meters

<u>Step-by-step explanation:</u>

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of x = 600 or x = -600, and y at 95.

We know that the equation of a parabola is in the form y=ax^2 and here it passes through the point (600, 95).

y=ax^2

95=a \times 600^2

a=\frac{95}{360000}

a=\frac{19}{72000}

So new equation for parabola would be y=\frac{19x^2}{72000}.

Now we have to find the height (y)of the cable when x= 300.

y=\frac{19 (300)^2}{72000}

y = 23.75 meters

How many slices of melon does Stephen eat over the weekend..........here is it....... She buys a melon and divides it into 6serv
Damm [24]
<span><u><em>Answer:</em></u>
2 slices

<u><em>Explanation:</em></u>
We know that the total number of servings is 6.
We also know that she ate </span>\frac{1}{3}<span> of the servings during the weekend.

This means that we need to calculate </span>\frac{1}{3}<span> of the total servings to know the amount she ate.

<u>This is done as follows:</u>
she ate = </span>\frac{1}{3} * 6 = \frac{1*6}{3} = \frac{6}{3}<span> = 2 slices

Hope this helps:)</span>
