Answer:
six points for all this ? HAHAHAHAHA LFMAO
Step-by-step explanation:
Consider this option:
the equation of ellipse is:
x²/a² + y²/b² = 11. if focuses are (6;0) and (-6;0), it means, that 2c=6-(-6)=12, ⇒ c=6.
2. c²=a²-b², it means, that a²-b²=36 - this is the 1st equation.
3. if c/a=3/5, it means, that c²/a²=9/25, ⇒ (a²-b²)/a²=9/25 - this is the 2d equation.
4. the 1st and the 2d equations are the system of two equations:
5. the required equation of the ellipse is:
Answer: Regression equation y= 14506.226(0.87)
1796.15
Step-by-step explanation:
Answer:
x=22
Step-by-step explanation:
4x+2+x+3x+2=180
collect like terms
4x+x+3x=180-(2+2)
8x=180-4
8x=176
make x the subject of the formula
x=176/8
x=22
