Answer:

The equation of the elipse is

[tex]\frac{x^2}{169} + \frac{y^2}{25} = 1[/tex]

Step-by-step explanation:

Equation of an elipse:

The equation of a elipse with centre [tex](x_c,y_c)[/tex] has the following format:

[tex]\frac{(x - x_c)^2}{a^2} + \frac{(y - y_c)^2}{b^2} = 1[/tex]

Centre at (0,0):

Means that [tex](x_c,y_c) = (0,0)[/tex].

So

[tex]\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1[/tex]

Vertex at (13,0):

Vertex at 13 means that [tex]a = 13, a^2 = 13^2 = 169[/tex]

Focus at (-12,0):

Means that [tex]c = 12, c^2 = 12^2 = 144[/tex]

We have that:

[tex]a^2 = b^2 + c^2[/tex]

So

[tex]169 = b^2 + 144[/tex]

[tex]b^2 = 25[/tex]

So, the equation of the elipse is

[tex]\frac{x^2}{169} + \frac{y^2}{25} = 1[/tex]

2. Two numbers m and n have the following properties: (1) their sum is 26 and (2) n is five
more than twice m. Write a system of equations that models the two properties given (write
them with the word and between them).

3. Enter your math answer
Find the values of m and n by solving the system you wrote in question 2

Answers

Answer:

m + n = 26 and n = 2m + 5

m = 7, n = 19

Step-by-step explanation:

Because we know that the sum of m and n is 26, we get the first equation. For the second equation, we are told that n is five more than twice m. So we multiple m by 2 and then add 5 to that to get what n is. This is our second equation.

We plug the second equation in for n in the first equation to get

m + (2m + 5) = 26

3m + 5 = 26

3m = 21

m = 7

And then for n, we solve the first equation to get

7 + n = 26

n = 19

Use compound interest to find the total amount for $845 at 1.25% for 6.5 years

Answers

Answer:

$911.02

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.25%/100 = 0.0125 per year,

then, solving our equation

I = 845 × 0.0125 × 6.25 = 66.015625

I = $ 66.02

The simple interest accumulated

on a principal of $ 845.00

at a rate of 1.25% per year

for 6.25 years is $ 66.02.

calculate the total distance Mary runs in one week if she runs 7/8 mile a day

Answers

Answer:

1 3/4

Step-by-step explanation:

I did 7/8 times 7/1 (7 days as a fraction) = 1 6/8 then i simplified that to 1 3/4

Total distance Mary runs in one week if she runs 7/8 mile a day is,

⇒ 49 / 8 miles

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Mary runs 7/8 mile a day.

Since, We know that;

1 week = 7 days

Now, Total distance Mary runs in one week if she runs 7/8 mile a day is,

⇒ 7 x 7/8

⇒ 49 / 8 miles

Thus, Total distance Mary runs in one week if she runs 7/8 mile a day is,

⇒ 49 / 8 miles
