Write the equation of each ellipse in standard form with the given characteristics.
Eddi Din [679]

Answer:

Step-by-step explanation:

The foci are horizontally aligned.

horizontal ellipse:

(x-h)²/a² + (y-k)²/b² = 1

center (h,k)

vertices (h±a,k)

length of minor axis = 2b

foci (h±c,k), c² = a²-b²

Apply your data and solve for h, k, a, and b.

foci (±3√19, 6)

h = 0

k = 6

Length of minor axis = 2b = 10

b = 5

foci (h±3√19, 6)

c = 3√19

c³ = a² - b²

171 = a² - 25

a²  = 196

x²/196 + (y-6)²/25 = 1

Question 1 of 10
lianna [129]

The remainder is 8 in the given synthetic division problem. which is the correct answer would be option (B).

<h3>What is the division operation?</h3>

In mathematics, divides left-hand operands into right-hand operands in the division operation.

In the given synthetic division, the coefficients of terms are 4,6, and -2.

Fill in the first coefficient as it appears on the bottom line.

Now multiply 1 by 4 and write the result (i.e., 4) underneath the second coefficient in the center line.

Now multiply 6 by 4 and write the result (i.e., 10) in the bottom row.

Now multiply 1 by 10 and write the result (i.e., 10) below the third coefficient in the center line.

Now add -2 with 10 and write the result (i.e., 8) in the bottom row.

The first two terms now indicate the polynomial coefficient, while the last term shows the remainder.

Therefore, the remainder is 8 in the given synthetic division problem.

The Mammoth Cave Discovery Tour includes an elevation change of 140 feet. This is 7/15 of the elevation change on the Wild Cave
Alexus [3.1K]

140 = (7/15)x

140/(7/15) = x/(7/15)

300 = x

The elevation change of the Wild Cave tour is 300ft.

Mr. Fulton bought 12 1/2 pounds of ground beef for the cookout. He plans on using 1/4 pound of ground beef for each hamburger. H
vekshin1

Answer:

Mr. Fulton can make 50 hamburgers.

Step-by-step explanation:

Given:

Total amount of ground beef = 12\frac{1}{2} \ pounds

12\frac{1}{2} can be Rewritten as \frac{25}{2}

Total amount of ground beef = \frac{25}{2}\ pounds

Amount of beef used for each hamburger = \frac{1}{4}\ pound

We need to find the number of hamburgers could he make.

Solution:

Now we can say that;

number of hamburgers can be calculated by Total amount of ground beef divided by Amount of beef used for each hamburger.

framing in equation form we get;

number of hamburgers = \frac{\frac{25}{2}}{\frac{1}{4}} = \frac{25}{2}\times \frac{4}{1} = 50

Hence Mr. Fulton can make 50 hamburgers.
