What are the solution of a quadratic equation 49x^2 = 9
1 answer:
Answer:
x = ±3/7
Step-by-step explanation:
49 x^2 = 9
Divide each side by 49
49/49 x^2 = 9/49
x^2 = 9/49
Take the square root of each side
sqrt(x^2) = ±sqrt(9/49)
We know sqrt(a/b) =sqrt(a)/sqrt(b)
x = ±sqrt(9)/ sqrt(49)
x = ±3/7

volume cylinder
=3.14×2^2×5
=62.8 cubic inches
volume sphere
=4/3×3.14×2^3
=33.49
difference between cylinder and sphere
=62.8-33.49
=29.31 cubic sphere
