Answer:
(x²/4) + (y²/16) ≤ 1
Step-by-step explanation:
The general form of the ellipse in the graph is
x²/4 + y²/16 = 1
we want to find the inequality which represents the shaded area this will determine whether which of the following 2 choices are correct
Choice 1: x²/4 + y²/16 ≥ 1
Choice 2: x²/4 + y²/16 ≤ 1
we note that point (0,0) lies inside the shaded area. Which means if we substitute (0,0), it should create an equality that is valid.
try choice 1: 0²/4 + 0²/16 = 0 ≥ 1 (not valid because obviously zero is smaller than 1)
try choice 1: 0²/4 + 0²/16 = 0 ≤ 1 (this is valid, hence choice 2 is the answer)
Answer:
All the fields will be harvested in 6.25 days
Step-by-step explanation:
because 75 ÷ 12 and 62.5 ÷ 12 is 6.25
I think the answer is 8.5 h
Answer:
1.
Step-by-step explanation:
Scale factor is 1 because the triangle and image are congruent ( same shape and size).
Check the picture below.
let's recall that the point of tangency with the radius chord is always a right-angle.
