How do you round off 639,121 to the nearest ten thousand?
maxonik [38]
You want to find the closest ten thousand that there is to 639,121.

So a ten thousand is basically anything that ends with four or more zeros.

For example:

530000 would be a ten thousand because it has four zeros at the end.

So you can see what the closest ten thousands are to 639,121 would be.

They would be:

630,000 and 640,000

Since they both have four zeros at the end.

Now you can just tell that 639,121 is closer to 640,000 because the digit in the thousands place, 9, is closer to 10 than 0.

Hope this helped :)

Write the equation of the conic section satisfying the given conditions. focus at the pole, e = 3/4, horizontal directrix 2 unit
hjlf

Answer:

The equation in the polar form is;

r = \dfrac{6}{4 + 3  \cdot sin(\theta)}

Step-by-step explanation:

 e = 3/4  > 1, we have an hyperbola    

The polar equation of a conic is of the form;

For vertical directrix

r = \dfrac{k \cdot e}{1\pm e \cdot cos (\theta)}

For horizontal directrix

r = \dfrac{k \cdot e}{1\pm e \cdot sin(\theta)}

Where;

k = Distance from the focus to the directrix = 2

We have;

r = \dfrac{2 \cdot \dfrac{3}{4} }{1 + \dfrac{3}{4}  \cdot sin(\theta)}

r = \dfrac{\dfrac{3}{2} }{1 + \dfrac{3}{4}  \cdot sin(\theta)}

Which gives the equation in the polar form as follows;

r = \dfrac{6}{4 + 3  \cdot sin(\theta)}.

Marcus is comparing the costs of two cellular phone services.
kolbaska11 [484]

The true statements about Marcus graph are:

  • The initial cost of phone service 1 is greater than the initial cost of phone service 2
  • The unit rate of phone service 2 is greater than the unit rate of phone service 2

<h3>How to determine the true statement</h3>

From the complete question, we have the following parameters:

<u>Phone service 1</u>

  • Initial cost: $40
  • Rate: $8.50 per service

<u>Phone service 2</u>

  • Initial cost: $30
  • Rate: $10.50 per service

By comparing the above parameters:

  • The initial cost of phone service 1 is greater than the initial cost of phone service 2
  • The unit rate of phone service 2 is greater than the unit rate of phone service 2

The above statements represent the true statements about the Marcus' graph
