Answer:
The answer to your question is e =
Step-by-step explanation:
Data
Ellipse = 36x² + 4y² = 9
e = ?
Formula
e = c/a
Process
1.- Convert the equation of the ellipse to the canonical form
36x² + 4y² = 9
- Divide by 9 both sides
36/9x² + 4/9y² = 9/9
4x² + 4/9y² = 1
x² /(1/4) + y² / (9/4) = 1
b² = 1/4 b = 1/2
a² = 9/4 a = 3/2
2.- Find c
a² = b² + c²
c² = a² - b²
Substitution
c² = 9/4 - 1/4
Simplification
c² = 8/4
c² = 2
c= 
3.- Find the eccentricity
e = 
e =
Answer:
(7y + 4) • (5y + 9)

Answer:
$966
Step-by-step explanation:
Sam's investment = 828
Paul's investment will be temporarily marked as x.
We need to divide 828 by 6 = 138 to find the result, x.
We multiply that by 7. 7 x 138 = 966.
We can write in 3 different ways:
828 : 966
828/966
(or in fraction form, I don't have a fraction line.
Answer:
m=5
Step-by-step explanation:
13=2m+5 is the same as 2m+5=15
15-5= 10
10÷2= 5
m=5
