Answer: 1. 200, 2. 300
Step-by-step explanation:
40 * 10/2 = 400/2 = 200
or this way:
40 = 20%
40/2 = 20
20 = 10%
20 * 10 = 200
——————————————
90 * 10/3 = 900/3 = 300
or this way:
90 = 30%
90/3 = 30
30 = 10%
30 * 10 = 300
Answer:
40
Step-by-step explanation:
Answer: 1. What are the focus and directrix of a parabola? Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).
2.The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle.
