Step-by-step explanation:
The largest possible ellipse will have a semi-minor axis of 2 feet and a semi-major axis of 4 feet. If we center the board on the origin of the cartesian coordinate plane, we can derive the location of the foci and thus, the length of string he will need:
x^2 / 16 + y^2 / 4 = 1
Vertices:
(-4 , 0) , (4 , 0)
(0 , -2) , (0 , 2)
If two line segments intersect at 90 degrees, then two line segments are perpendicular.
Answer:
Multiplying the numerators and denominators, we get 21 / 48 = 7 / 16.
120+4w
4 new songs each week so that would be 4 multiplied by the number of weeks but we don’t have a number we just have a variable so that would be 4w
And there was already 120 songs so we want to add that in with the amount of songs added each week
120 + 4w
3/5 and 2/5 5 is the common denominator for both fractions.
