The answer would be 30.
60/2 = 30
90/2 = 45
120/2 = 60
The answer to the square root of 40 is 6.33
Answer:
m² - 4m - 45 = 0
Step-by-step explanation:
(m + 5)(m - 9) = 0
m² + 5m - 9m - 45 = 0
m² - 4m - 45 = 0
9514 1404 393
Answer:
(a) x^2/16 +y^2/9 = 1
Step-by-step explanation:
The form for the equation of an ellipse centered at the origin is ...
(x/(semi-x-axis))^2 +(y/(semi-y-axis))^2 = 1
The vertex values tell you the semi-x-axis is 4 units, and the semi-y-axis is 3 units. Then you have ...
(x/4)^2 +(y/3)^2 = 1
x^2/16 +y^2/9 = 1
__
In case you don't remember that form, you can try any of the points in the equations. The equation that works will quickly become apparent.
