f (x)= 1/x-4 -6. Find the inverse of f(x) and its domain.

Answer:

9x^2 +30x +26.  g(f(x)) = (3x + 5)^2 + 1

Step-by-step explanation:

The value of function g(f(x)) will be (3x + 8).

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

The value of functions are;

f(x) = 3x + 5 and g(x) = x + 1

Now, Find the value of function f(g(x)) by substituting the given values as;

f(g(x)) = f (x + 1)

        = 3 (x + 1) + 5

        = 3x + 3 + 5

        = 3x + 8

Thus, The value of function g(f(x)) will be (3x + 8).

sum of interior angle of polygon=(n-2)180=(29-2)180=27×180=4860°

Answer:

43

Step-by-step explanation:

v+47 is equal to 90 degrees, because it's a right angle

v+47=90

to get 90 in this equation, v must equal 43.

that means v=43

Answer:

$30

Step-by-step explanation:

Given that :

Amount earned for mowing = $45

Amount spent on music = $5

Amount earned for washing neighbor's car = $10

Amount saved = half or remaining amount

Amount of dollars Fred keeps =

Amount Fred keeps:

[(Amount earned - amount spent) / 2] + $10

[($45 - $5) / 2] +

($40 / 2) + $10

= $20 + $10

= $30

Answer:

Step-by-step explanation:

A.)

The problem with the here is that we might have introduced bias into our sample by failing to randomize the assignment of gender. By pacing the male gender in the treatment group and females into the control group, this might spring up a spurious association in our experiment as a result of a possible confounding variable, gender. Therefore, assignment of subject shouldn't be on the basis of gender.

2.)

Using a coin toss in placing subjects into groups will give a good random assignment, however, since only ten subjects are available and of which 5 will be placed into each group, there is no certainty that there will be equal number of heads and tails during the 10 flips. Alternatively, a random selection of the name of the 10 subjects could be chosen from a raffle.

3.)

Each batch of rat might be homogenous and hence will affect our experiment and definitely our conclusion. It would be best to assign rats from each batch to all treatment groups in other to obtain a good random design

Answer: x ≥ 7

Step-by-step explanation:

You have to square both sides of the equation. You can manipulate an equation or function any way imaginable as long as it is done equally and helps the problem become easier. If we square this, the radical will cancel and we will get two trinomials equal to each other.

[tex]x^2-14x+49=(x-7)^2\\x^2-14x+49=x^2-14x+49[/tex]

We can see the two expressions are exactly equal to each other. All real numbers are solutions, besides a few. These few are when the radical is equal to a negative number. So lets set up an inequality stating that the radical must be greater than or equal to 0.

[tex]x^2-14x+49\geq 0\\(x-7)^2 \geq 0\\x \geq 7[/tex]

Answer:

$252

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 1200 × 0.03 × 7 = 252

I = $ 252.00

The simple interest accumulated

on a principal of $ 1,200.00

at a rate of 3% per year

for 7 years is $ 252.00.

Answer:

Step-by-step explanation:

North and Souths get added together. North is positive and South is negative.

East and West get added together. East is positive and West is negative.

This will get us two numbers for a triangle that we can make starting at the origin and ending where the two numbers take us.

10 miles north + 14 miles north = 24 miles north

10 + 14 = 24

5 miles west + 12 miles east = 7 miles east

-5 + 12 = 7
