A circle with a radius of 5 is inscribed in a equilateral triangle. What is the area of the triangle's area minus the circle's a

Aleonysh [2.5K]

First off, the area of the circle would be 78.54

Now, you would do (area of the triangle)--- AT-78.54=answer

I don't know how to find the area of the triangle with just the circle's radius, so this is all I can do. I'm sorry!

Which expression is the simplest form of -(4x + y)n + 2(x - 3y)

Marina86 [1]

Answer:

$\boxed{\bold{-4nx-ny+2x-6y}}$

Explanation:

Rewrite:

= $\bold{-n\left(4x+y\right)+2\left(x-3y\right)}$

Expand $\bold{-n\left(4x+y\right): \ -4nx-ny}$

= $\bold{-4nx-ny+2\left(x-3y\right)}$

Expand $\bold{2\left(x-3y\right): \ 2x-6y}$

= $\bold{-4nx-ny+2x-6y}$

Mordancy.

<u>Part A</u>

<u /> $4x^2 -7x-15=0\\\\(4x+5)(x-3)=0\\\\x=-\frac{5}{4}, 3$

So, the x-intercepts are $\boxed{\left(-\frac{5}{4}, 0 \right), (3,0)}$

<u>Part B</u>

The vertex will be a minimum because the coefficient of $x^2$ is positive.

The x-coordinate of the vertex is $x=-\frac{-7}{2(4)}=\frac{7}{8}$

Substituting this back into the function, we get $f\left(\frac{7}{8} \right)=4\left(\frac{7}{8} \right)^2 -7\left(\frac{7}{8} \right)^2 -15=-\frac{289}{16}$

So, the coordinates of the vertex are $\boxed{\left(\frac{7}{8}, -\frac{289}{16} \right)}$

<u>Part C</u>

Plot the vertex and the x-intercepts and draw a parabola that passes through these three points.

The graph is shown in the attached image.
