Hello,

Answer A: (-infini,3/2)
Vertex is (3/2,41/4) and the curve is turning its concavity down.
f'(x)=-2x+3=0==>x=3/2

Graph x=2.5 will do anything
almond37 [142]

Okay, so you're going to go along the line that goes side to side, and then find positive 2. It'll be on the right side. From there, go half way in and insert a line going up and down.

Bam! You've got yourself x= 2.5 graphed!

Help meeee with this questionnnnnnnnnn!!!!!!!!!!!!
Dafna1 [17]

Given:

The scale factor between two circles is \dfrac{2x}{5y}.

To find:

The ratio of their areas.

Solution:

We know that, all circles are similar.

The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.

The scale factor is the ratio of the corresponding sides.

Ratio of areas of circles = Square of scale factor between two circles

\text{Ratio of areas of circles}=\left(\dfrac{2x}{5y}\right)^2

\text{Ratio of areas of circles}=\dfrac{(2x)^2}{(5y)^2}

\text{Ratio of areas of circles}=\dfrac{4x^2}{25y^2}

Therefore, the correct option is D.
