What is the first operation used to evaluate 5+7•6-2÷4

1 answer:

Multiply 7x6 since when using pemdas, multiplication and division can be inverted, i.e. if multiplication is before division then you multiply and vice versa.

What is the focus of the parabola? y=−1/4x2−x+3

alex41 [277]

Answer: Focus = (-2, 3)

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

$y=-\dfrac{1}{4}x^2-x+3\\\\\rightarrow a=-\dfrac{1}{4},\ b=-1$

First let's find the vertex. We do that by finding the Axis-Of-Symmetry:

$AOS: x=\dfrac{-b}{2a}\quad =\dfrac{-(-1)}{2(\frac{-1}{4})}=\dfrac{1}{-\frac{1}{2}}=-2$

Then finding the maximum by inputting x = -2 into the given equation:

$y=-\dfrac{1}{4}(-2)^2-(-2)+3\\\\y=-1+2+3\\\\y=4$

The vertex is: (-2, 4)

Now let's find p, which is the distance from the vertex to the focus:

$a=\dfrac{1}{4p}\\\\\\-\dfrac{1}{4}=\dfrac{1}{4p}\\\\\\p=-1$

The vertex is (-2, 4) and p = -1

The focus is (-2, 4 + p) = (-2, 4 - 1) = (-2, 3)
