Answer:
A. & B.
Step-by-step explanation:
General form is ax2 + bx + c = 0.
Must contain an x2 term
Must NOT contain terms with degrees higher than x2 eg. x3, x4 etc
It's the 2,7,3,2 one or the third one
I'm not so sure but from what I know the answer is option 2
Answer:
Correct option: C (it is missing the point)
0.53
Step-by-step explanation:
When a ball rolls one revolution, the distance travelled is the length of its circunference, that is:
Circunference = pi * diameter
So, to solve this question, we can use a rule of three:
1 revolution -> pi * d
60 revolutions -> 100 feet
100 = 60 * pi * d
d = 100 / (60 * pi) = 0.53 feet
Correct option: C (it is missing the point).
Hello! :)

9 = (3/8)y
Solve for y.
Isolate y by dividing both sides by 3/8, or multiplying by its reciprocal (8/3)
9 · (8/3) = (3/8)y · (8/3)
72 / 3 = y
y = 24
