Answer:

f( -  \frac{b}{2a} )

Step-by-step explanation:

When you not given the vertex form, the you are given the standard form:

f(x) = a {x}^{2}  + bx + c

The value of k, is the y-value of the vertex of the function.

To find the value of k, you plug in

x =  -  \frac{b}{2a}

In order works, you evaluate

f( -  \frac{b}{2a} )

This will give you the k-value

33/4 is the same as 8 1/4

so that means that matt bought the Volvo for 8 1/4 times as much as the car his parents bought.

Can someone please help me ;-; this is due today
IRISSAK [1]

Answer:

The correct answer: F (Scalene) and A (Acute)

Step-by-step explanation:

F. (Scalene):  By definition, a scalene triangle is a triangle that has no equal sides, and no equal angles. This definition matches your given triangle, since it has no equal sides and angles.

A. (Acute): By definition, an acute triangle is a triangle in which all the internal angles are less than 90 degrees. This definition matches your given triangle, since all of the internal angles are less than 90 degrees.

The given triangle is not obtuse, equilateral, right, and isoceles.

It is <u>not</u> an <em>obtuse </em>triangle because none of the angles are greater than 90 degrees.

It is <u>not</u> an <em>equilateral</em> triangle because its sides are not equal.

It is <u>not</u> a <em>right</em> triangle because none of its internal angles measure 90 degrees.

And it is <u>not</u> an <em>isoceles</em> triangle because by definition, an isoceles triangle must have two equal sides. Your given triangle has no equal sides.
