Hello there!

You need to look for a calculator on the internet that can do that.

I used demos, it is not bad!

As always, it is my pleasure to help people like you!

3 = q/11 i need it real quick

makkiz [27]

Answer:

$q=33$

Step-by-step explanation:

So we have:

$3=\frac{q}{11}$

Multiply both sides by 11:

$11(3)=(11)\frac{q}{11}$

The right side cancels:

$11(3)=q$

Multiply the left:

$33=q$

Thus, the value of q is 33.

The equation of a parabola is y=x^2-10x+27. Write the equation in vertex form

azamat

Answer:

$\large \boxed{y = (x - 5)^{2} + 2 }$

Step-by-step explanation:

y = x² - 10x + 27

y = ax² + bx + c

This is the general form of the equation for a parabola.

We must convert it to the vertex form

y = (x - h)² + k, where (h,k) are the coordinates of the vertex.

We can do this by completing the square.

$\begin{array}{rcll}y & = & x^{2} - 10x + 27 & \\y - 27 & = & x^{2} - 10x & \text{Subtracted 27 from each side}\\y - 27&= & x^{2} - 10x + 25 - 25 & \text{Added and subtracted (b/2)}^{2}\\y - 27&= & (x - 5)^{2} - 25 & \text{Wrote the first three terms as the square of a binomial}\\y& = & \mathbf{(x - 5)^{2} + 2} & \text{Added 27 to each side}\\\end{array}\\\text{The vertex form of the parabola is $\large \boxed{\mathbf{y = (x - 5)^{2} + 2 }}$}$ The figure below shows that your parabola has its vertex at (5,2).

Write 5/3 as a mixed number

Lostsunrise [7]

5 / 3 is improper fraction.
To change it into mixed fraction you have to divide 5 by 3.
i.e. 1 is the quotient, 3 is the divisor, 5 is the dividend, and 2 is the reminder.

To write it in the mixed fraction you will only need the quotient, remainder and divisor.
First you will write quotient in the middle then the remainder divided by divisor
i.e. 1 2/3 where 1 is quotient, 2 is remainder and 3 is divisor.
