Determine whether these two functions are inverses. Show your work please. f(x)= 1/x+4-9; g(x)=1/3x+9
BigorU [14]

Answer:  No they are not inverses.

<u>Step-by-step explanation:</u>

If they are inverses,  then the inverse of f(x) will equal g(x).

y=\dfrac{1}{x+4}-9\\\\\\\text{Swap the x's and y's:}\\x=\dfrac{1}{y+4}-9\\\\\\\text{Solve for y:}\\x+9=\dfrac{1}{y+4}\\\\y+4=\dfrac{1}{x+9}\\\\y=\dfrac{1}{x+9}-4

f⁻¹(x) ≠ g(x) so they are not inverses

Explain why it makes sense for this situation to have a linear equation
IgorC [24]

Answer:

The line of best fit for your specific question is a linear equation.

Step-by-step explanation:

A linear equation has a constant rate of growth/decline and the growth/decline rate will never change in an linear equation.

If you draw a line that approximately splits between all the data plots, you will notice the line you drew is very close to the data points.

If the data plots was a quadratic, it would be very hard to draw a line of best fit.

Linear equations can easily be identified in a graph because it is a straight line.

Perhaps insert this equation into your graphing calculator or other graphing software online (like Desmos): y = 3x+2

A quadratic equation can also easily be identified in a graph because, in most cases, it looks like a U.

Take these examples: y = 3x^2+5x+2 or y=-2x^2+10x+30

Evaluate x/y + 3z^2 for x= 2/3, y= 6/7, and z=3
prohojiy [21]

x/y + 3z^2 for x= 2/3, y= 6/7, and z=3

=2/3  /  6/7  + 3(3^2)

=2/3 * 7/6 + 3(9)

= 7/9 + 27

= 7/9 + 243/9

= 250/9

answer is a. 250/9

Find the perimeter and round to the nearest tenth
tekilochka [14]

Answer:

Perimeter = 12.0 m

Step-by-step explanation:

Perimeter = AB + AC + BC

AB = 5 m

B = 53°

Use trigonometric functions to find AC and BC respectively.

✔️Find AC:

Reference angle = 53°

Opposite side length = AC

Hypotenuse = 5 m

Apply SOH, which is:

Sin 53 = Opp/Hyp

Sin 53 = AC/5

5*Sin 53 = AC

AC = 3.99317755 ≈ 4 m

✔️Find BC:

Reference Angle = 53

Hypotenuse = 5 m

Adjacent = BC

Apply CAH, which is:

Cos 53 = Adj/Hyp

Cos 53 = BC/5

5*Cos 53 = BC

BC = 3.00907512 ≈ 3.0 m

✔️Perimeter = 5 + 4 + 3 = 12.0 m
