Answer:

AC 29

CB 15

Step-by-step explanation:

5x-6+2x+1=44 add like terms

7x-5=44

7x= 49

x= 7

plug back in

5(7)-6 = 29

2(7)+1 = 15

A company estimates that the revenue (in dollars) from the sale of x doghouses is given by R(x)=14,000ln(0.01x+1). Use the diffe

Dafna11 [192]

Answer:

The change in revenue from the sale of one more doghouse if 110 doghouses have already been sold is dR/dx=66.67 $/doghouse.

Step-by-step explanation:

We have a revenue function that is:

$R(x)=14,000\cdot \text{ln}(0.01x+1)$

We have to approximate the change in revenue from the sale of one more doghouse, if 110 doghouses have already been sold.

That is the marginal revenue at x=110.

The marginal revenue is expressed as the first derivative of the revenue.

Then, we calculate the derivative of R:

$\dfrac{dR}{dx}=\dfrac{d}{dx}[14,000\cdot \text{ln}(0.01x+1)]\\\\\\\dfrac{dR}{dx}=14,000\dfrac{d}{dx}[\text{ln}(0.01x+1)]\\\\\\\dfrac{dR}{dx}=14,000\cdot\dfrac{1}{0.01x+1}\cdot \dfrac{d}{dx}(0.01x+1)\\\\\\\dfrac{dR}{dx}=14,000\cdot\dfrac{1}{0.01x+1}\cdot 0.01\\\\\\\dfrac{dR}{dx}=\dfrac{14,000}{x+100}$

We then evaluate this marginal revenue at point x=110:

$\dfrac{dR}{dx}_{|x=110}=\dfrac{14,000}{110+100}=\dfrac{14,000}{210}=66.67$

What are all the digits of pie?

Artemon [7]

'Pi' is an irrational number. It can never be completely written with digits.

Here are the first 15 decimal places: 3.14159 26535 89792

A supercomputer lab in Japan has calculated <u>4 trillion</u> digits of pi,
and it still doesn't end.

With higher mathematics, it's possible to <u>prove</u> that pi never ends.
So, no matter how many digits somebody gives you for pi, there are
still an infinite number more after those.

The ratio of the measures of the three angles in a triangle is 2:9:4. Find the measures of the angles.

Alex777 [14]

Answer:

Let the three angles be 2x,9x & 4x

By the problem,2x+9x+4x=180

15x=180

x=180/15

x=12

there fore the angles are

2x= 2*12=24°

9x=108°

4x=48°
