How to determine if two functions are inverses?

1 answer:

3 0

You will compose the functions (that is, plug x into one function, plug that function into the inverse function, and then simplify) and verify that you end up with just "x". Here's what it looks like:Determine algebraically whether f (x) = 3x – 2 and g(x) = (x + 2)/3are inverses of each other.

Answer:

Area of figure: (4y - 7)(x + 6y + 1)

Step-by-step explanation:

The height of the figure is 4y - 7 and the length is x + 6y + 1.

The area of the figure is the product of height and length, or:

(4y - 7)(x + 6y + 1)

A guy wire attached to the top of a radio antenna

dusya [7]

Answer:

49.47 m

Step-by-step explanation:

You will need to use the cosine function

which is the ratio adjacent side/hypotenuse

So, let x = length of guy wire

then cos 14 = 48/x

x cos 14 = 48

x = 48/cos 14

= 49.47 m

Note: You must memorize the definitions of all the trig functions so you can do problems like this one. OK?

Michael obtains a 30/8 balloon mortgage to finance $425,500 at 6.55%. How much principal and interest will he have already paid

STALIN [3.7K]

Answer:

$259 532

Step-by-step explanation:

Step 1. Calculate the monthly payments on a 30-year loan.

The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate

of r % is

$P = A(\frac{r}{1-(1+r)^{-n}})$

Data:

We must express the interest rate on a monthly basis.

i = 6.55 %/yr = 0.545 83 %/mo = 0.005 4583

A = $425 500

n = 360 mo

Calculation:

$P = 425 500(\frac{0.005 4853}{1-(1+0.005 4583)^{-360}})$

$P = \frac{2332.22}{{1- {1.005 4583}}^{-360}}$

$P = \frac{2332.52}{1 – 0.140907}$

$P = \frac{2332.52}{0.859 093}$

P = $2703.46

B. Total Payment (T) after 8 years

T = nP

T = 96 × 2703.46

T = $259 532

Michael will have paid $259 532 at the end of eight years.
