Consider the function attached below
Masja [62]

Answer:

2

Step-by-step explanation:

Hello,

x=(fof^{-1})(x)=f(f^{-1}(x))=\sqrt{2f^{-1}(x)}+5\\\sqrt{2f^{-1}(x)} =x-5\\2f^{-1}(x)=(x-5)^2\\f^{-1}(x)=\dfrac{(x-5)^2}{2}

now let's replace x by 7 it comes

f^{-1}(7)=\dfrac{(7-5)^2}{2}=\dfrac{2^2}{2}=2

hope this helps

The height of the tide over time is shown on the graph. Which of the following equations can be used to reasonably model the dat
Murljashka [212]

Answer:

Option 1.f(x) = -3sin(\frac{\pi }{6}x)+3

Step-by-step explanation:

The height of the tide over the time is shown on the graph.

Its a periodic function (sine graph) plotted on a graph in which variables are

Amplitude a = (6-0)/2 = 3

Period = 15-3 = 12

Therefore b = 2π/period = 2π/12 = π/6

horizontal shift = 0

Vertical shift = 3

Since the function starts with negative sign that means its below the x-axis.

So as per standard formula of f(x) = asin(bx+c)+d

option which matches all these parameters is Option 1. f(x) = -3sin(\frac{\pi }{6}x)+3

X/72 = 135/90 what is x?
enot [183]
Hey! I'll provide the steps required.

First, solved the proportion by cross multiplication.

X(90) = (135)(72)

Then use the commutative property to reorder the terms as well as multiply the numbers.

90x = 9720

Finally, divide it by 90.

x = 108
