A circle is 360 degrees so 1/18 of the circle will be 20 degrees. For 5 parts the total will be 100 degrees (20*5)

Verify that f and g are inverses functions using composition , show your steps
pshichka [43]

Answer:

See explanations below

Step-by-step explanation:

Given the functions

f(x) = 12x - 12

g(x) = x/12 - 1

To show they are inverses, we, must show that f(g(x)) = g(f(x))

f(g(x)) = f(x/12 - 1)

Replace x with x/12 - 1 into f(x)

f(g(x)) =12((x-12)/12) - 11

f(g(x)) =  x-1 - 1

f(g(x)) =x - 2

Similarly for g(f(x))

g(f(x)) = g(12x-12)

g(f(x)) =(12x-12)/12 - 1

12(x-1)/12 - 1

x-1 - 1

x - 2

Since f(g(x)) = g(f(x)) = x -2, hence they are inverses of each other

Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicates that you took 7350 steps today. Wr
ivolga24 [154]

Answer:

7,000

Step-by-step explanation:

The number of actual steps is x.

x + x(.05) = 7350    This is actual steps plus the extra 5% equals the number shown on the tracker.

Pull out x

x (1+.05) = 7350

x (1.05) = 7350     Divide by 1.05

(x (1.05))/1.05 = 7350/1.05

x = 7,000

Write each trigonometric ratio as a fraction in simplest form. show all supporting work
Nesterboy [21]

Answer: \frac{x}{20}

Step-by-step explanation:

Sine uses the ratio,  \frac{opposite}{hypotenuse} so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.

sinA=\frac{x}{20}

You can't reduce this any further because there is an unknown variable.
