True or false: Polar equations can describe graphs as functions, even when their equations in the rectangular coordinate system are not functions.

Answers

Answer 1

Answer: The statement above is true. Polar equations indeed can describe graphs as functions, even if when the equations in the rectangular coordinate system are not one of the functions. Polar equations can be graphed accurately using hands by using the Polar Coordinate System.

Answer 2

Answer:

Answer:

The answer is true.

Step-by-step explanation:

A polar equation describes the relation between r and θ. Here 'r' is the distance from the origin to a point curve. 'θ' is the angle made by a point on a curve, the pole, and the positive x-axis.

So, the statement - Polar equations can describe graphs as functions, even when their equations in the rectangular coordinate system are not functions - is true.

16/8 into a mixed number

Answers

ok well the answer will be 2 because 8+8=16 and 8 can go into 16 2 times.

the answer is
2/1
because 8 times 2 is 16 and if you divide 16 by 8 u will get 2 and 8 divided by 8 is 1

19. A store manager purchases a piece of furniture for $456.00. To determine the selling price, the manager increases the purchase cost by 125%. A customer buys the furniture and pays an additional 8% sales tax. How much does the customer pay for the furniture?

Answers

Answer: The customer pays $1108.08 for the furniture.

Step-by-step explanation:

1. Determine the selling price of the furniture.

2. Calculate the sales tax.

3. Add the sales tax to the selling price.

Step 1: Determine the Selling Price

The store manager increases the purchase cost by 125%. To find the selling price, we first calculate the increase:

$\[\text{Increase} = \text{Purchase Cost} * \frac{\text{Percentage Increase}}{100}\]\[$

$\text{Increase} = \$456.00 * (125)/(100) = \$456.00 * 1.25 = \$570.00\]$

Now, we add this increase to the original purchase cost to find the selling price:

$\text{Selling Price} = \text{Purchase Cost} + \text{Increase}\]\[\text{Selling Price} = \$456.00 + \$570.00 = \$1026.00$

Step 2: Calculate the Sales Tax

The customer pays an additional 8% sales tax on the selling price. To find the sales tax, we use:

$\[\text{Sales Tax} = \text{Selling Price} * \frac{\text{Sales Tax Percentage}}{100}\]\[$

$\text{Sales Tax} = \$1026.00 * (8)/(100) = \$1026.00 * 0.08 = \$82.08\]$

Step 3: Add the Sales Tax to the Selling Price

Finally, to find out how much the customer pays in total, we add the sales tax to the selling price:

$\text{Total Cost} = \text{Selling Price} + \text{Sales Tax}\]\[\text{Total Cost} = \$1026.00 + \$82.08 = \$1108.08$

The customer pays $1108.08 for the furniture.
