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]

Consider the baggage check-in process of a small airline. Check-in data indicate that from 8 a.m. to 9:30 a.m., 360 passengers checked in. Moreover, based on counting the number of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 30.
Required:
How long did the average passenger have to wait in line?
Answer:
[tex]Average = 7.5\ mins[/tex]
Step-by-step explanation:
Given
[tex]Time = 90\ mins[/tex] i.e. 8am to 9:30am
[tex]Total\ Passengers = 360[/tex]
[tex]Average\ Passengers= 30[/tex]
Required
Determine the average waiting time
The average waiting time is calculated as:
[tex]Average = \frac{Average \ Passengers}{Total\ Passengers} * Time[/tex]
[tex]Average = \frac{30}{360} * 90\ mins[/tex]
[tex]Average = \frac{30* 90\ mins}{360}[/tex]
[tex]Average = \frac{2700\ mins}{360}[/tex]
[tex]Average = 7.5\ mins[/tex]
Hence, the average waiting time is 7.5 minutes

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
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
-4(2x-7)=12 give the value of x. Enter your value for x and your explanation or steps used to solve for x
Answer:
2
Step-by-step explanation:
-4(2x-7)=12
(2x-7)=12/(-4)
2x-7=-3
2x= -3+7
2x= 4
x= 4/2
x=2
Use compound interest to find the total amount for $845 at 1.25% for 6.5 years
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
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
