Answer:
Radius = 2 yd
Diameter = 4 yd
Step-by-step explanation:
circumference = 2
r (where r is the radius)
if circumference = 4
, then
4
= 2
r
⇒ 4 = 2r
⇒ 2 = r
⇒ radius = 2 yd
diameter = 2r
= 2 x 2
= 4 yd

Answer:
Step-by-step explanation:
The sum of complementary angles is 90°.
∠ABD +∠BDC = 90°
(y -30)° +(2y)° = 90°
3y = 120 . . . . . . . . . . . . divide by °, add 30
y = 40 . . . . . . . . . . . divide by 3
∠ABD = (40 -30)° = 10°
∠BDC = 2(40)° = 80°
The answer is 2.
Since you are subtracting C(x) from R(x), your equation would look like this.
P(x)=-.5x^2+800x-100-(300x+250)
which if you then simplify would be
P(x)=-.5x^2+500x-350
