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

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}})

<em>Data: </em>

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

<em>Calculation: </em>

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.
