Answer:
f(x) = -3(x+3)(x-1)
Step-by-step explanation:
x = -3 & 1; f(x) = 9
f(x) = a(x-r1)(x-r2)
f(0) = a(x-r1)(x-r2) = 9; 9 = a(0-(-3))(0-1)
9 = a(3)(-1); 9 = a(-3)
a = -3
f(x) = -3(x+3)(x-1)
1:5= 1/5 x 20/20= 20/100
20/100= 0.20
The bag contains 20% of pink marbles.
Answer: 
Each term is half of the previous one, so the common ratio is 1/2. Then to get from the first term to the nth term, you have to take n - 1 steps, multiplying by 1/2 each time and by 6000 to account for the first term.
i hope this helps! :D
Answer:
Therefore 70 year Marc's grandmother be 5 times of as Marc will be after (70-56) = 14 year.
Step-by-step explanation:
Given, Marc was born on his grandmother's 56th birthday.
Let , x year will Marc's grandmother be 5 times as Marc will be then.
At that time the age of Marc will be = (x-56) year
According to the problem,
x= 5(x-56)
⇔x = 5x - 280
⇔x-5x= -280
⇔-4x=-280
⇔x=70
Therefore 70 year Marc's grandmother be 5 times of as Marc will be after (70-56) = 14 year.
