Answer:

x = 27

Step-by-step explanation:

this problem is similar to a scale drawing where we can set up a proportion:

'x' is to 5 as 162 is to 30

x/5 = 162/30

cross-multiply:

30x = 810

x = 810/30

x = 27

Examine the following table, which defines the relationship y= f(x). Then, answer the question.

erastova [34]

The slope of the function is most positive either side of x=0 and x=2π.

On the interval [0, π/4], the average slope is $\dfrac{(\frac{\sqrt{2}}{2})}{(\frac{\pi}{4})} = \dfrac{2\sqrt{2}}{\pi}$

On the interval [7π/4, 9π/4], the average slope is $\dfrac{(\frac{\sqrt{2}}{2}-\frac{-\sqrt{2}}{2})}{(\frac{9\pi}{4}-\frac{7\pi}{4})}=\dfrac{2\sqrt{2}}{\pi}$

The average rate of change is highest on the intervals [0, π/4] and [7π/4, 9π/4].

5. Find the vertex and length of the latus rectum for the parabola.

olga55 [171]

Answer: (2,5)

Step-by-step explanation:

To find the x coordinate of the vertex, you will set x-2=0 and solve for x

x-2=0

+2 +2

x = 2

Now since we know the vertex has an x coordinate of 2 we have to solve for y by plotting in the x value.

y= 1/2(2-2)^2 + 5

y = 0 +5

y =5
