Write the equation of an ellipse with the following characteristics: center =(1,-3) vertices=(-6,-3),(8,-3)
Foci =(-4.7,-3),(6.7,-3)

Answers

Answer:

(x-1)²/49 + (y+3)²/16.51 = 1

Step-by-step explanation:

vertex (8,-3) Foci (6.7,-3) center (h,k) = (1,-3) , major axis parallel to x axis

a is the distance of the vertex from the center, and c is the distance of the foci from the center. b is semi-minor axis

b² = a² - c² Ellipse equation: (x-h)²/a² + (y-k)²/b² = 1

a = 8-1 = 7 c = 6.7 - 1 = 5.7

b² = 7² - 5.7² = 16.51

Ellipse equation: (x-1)²/49 + (y- -3)²/16.51 = 1 i.e. (x-1)²/49 + (y+3)²/16.51 = 1

Mrs.owens bought two candles for her dining room table. She paid with a $100 bill and received $32.16 in change. If sales tax is charged at a rate of 6% what was the price for one candle holder before taxes?

Answers

6% would typically be 6cents to every dollar so that’s odd. Any who
100-32.16=67.84/2=33.92
Then remove taxes per candle
33.92 has 2.04 for tax 6% = 6cents or 0.06
33.92-2.04=33.88 without tax per candle
Answer: 33.88$

The price for one candle holder before taxes is $30.88.

What is a tax?

It is an amount of money that a government requires people to pay according to their income, the value of their property, etc., and that is used to pay for the things done by the government.

The total payment including tax is $100.

The change received is $32.16.

The rate of sale tax is 6%.

The cost of one candle including tax is given by

(100 - 32.16) / 2 = 32.92

6% of a candle is given by

32.92 * 0.06 = 2.0352

The cost of one candle without tax is given by

32.92 - 2.0352 = 30.88

Hence, the cost of one candle without tax is $30.88.

Answers

The distributive property is when you use the number on the outside of the parentheses to multiply the numbers on the inside of parentheses. This is usually used when the option is given and there is a variable inside.

Now onto the question, 4(x + 5)

We can actually break this down into parts so it’s not just one thing.

(4)(x) + (4)(5) would be the broken down form.

Thus, the answer to your question is:
D. 4(x + 5) = (4)(x) + (4)(5)
