Step-by-step explanation:

what is the problem ?

first you need to put "1" in place of the x and calculate, and then you need to put "2" in place of the x and calculate.

just simple calculation !

(a)

R(1) = 1000×1² / (1² + 4) = 1000 / 5 = 200

$200 million

(b)

R(2) = 1000×2² / (2² + 4) = 4000 / 8 = 500

$500 million

there ! that's all that was needed.

A scale drawn on the map shows that 1 inch represents 40 miles. If tuo cities

ohaa [14]

Answer:

Im pretty sure its 1,000 miles (dont forget the unit)

Step-by-step explanation:

Determine if this problem is a inverse variation or direct variation problem! This means that:

equation would be:

1=40

25=x

cross multiply*

x=25*40

x=1,000 miles apart! (dont forget the unit)

If this doesnt work then try this equation!

1=40

25=x

Multiply 1*40 and 25 *x

40=25x......

40/25= 1.6

x=1.6! (Extra step)

Cheers!

Give an example of a rational function that has a horizontal asymptote at y = 1 and a vertical asymptote at x = 4.

Greeley [361]

Answer:

Possibility 1: $\frac{(x+1)(x+1)}{(x-4)(x+5)}$

Possibility 2: $\frac{(x+1)(x+3)(x-3)}{x(x-4)(x+5)}$

Possibility 3: $\frac{-4(x-4)(x+1)}{-4(x-4)(x-4)}$

There are infinitely many more possibilities.

Step-by-step explanation:

So we are looking for a fraction in terms of x.

We have a horizontal asymptote so that means the degree of the top has to equal to degree of the bottom. It is also at y=1 which means the coefficient of the leading term on top and bottom must be the same (but not zero) since the same number divided by the same number is 1.

Now we also have a vertical asymptote at x=4 which means we need a factor of x-4 on bottom.

So there is a lot of possibilities. Here are a few:

Possibility 1: $\frac{(x+1)(x+1)}{(x-4)(x+5)}$

You have the degrees are the same on top and bottom and the leading coefficients are the same. You also have that factor of (x-4) on bottom.

Possibility 2: $\frac{(x+1)(x+3)(x-3)}{x(x-4)(x+5)}$

Possibility 3: $\frac{-4(x-4)(x+1)}{-4(x-4)(x-4)}$

Now a factor of (x-4) can be canceled here but you still have a factor of (x-4) left on bottom so you still have the vertical asymptote. You also still have the same leading coefficient on top and bottom (-4 in this case) and the same degree.

I need help with numbers 15 and 18!!! what does x equal? help asap!!

Sav [38]

Answer:

15. x = 112 degrees

18. x = 120 degrees

Step-by-step explanation:

A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.

2a + 44 = 180

2a = 136

a = 68

Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.

x + 68 = 180

x = 112

We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.

3a = 180

a = 60

Now we do the same thing as last time to find x.

x + 60 = 180

x = 120
