Step-by-step explanation:
The answer is a.0
Concentric means these circles would have the same center, thus, the smaller circle must be inside the bigger circle. Any tangent line to the smaller circle wont be a tangent line to the bigger circle, since that tangent line would intersect at the bigger circle at 2 points. Any tangent line to the big circle will not touch the small circle... so the answer would be 0.
Answer:
1/3
Step-by-step explanation:
simplify
81^(-1/4)
= 1/81^(1/4)
= 1/[3×3×3×3]^(1/4). (factorize 81)
= 1/[3]^(4/4)
= 1/3
Step-by-step explanation:
2x^2+7x-3=0
by doing splitting the middle term we get/ <u>using quadratic eq we get-</u>
Let's solve your equation step-by-step.
2x2+7x−3=0
For this equation: a=2, b=7, c=-3
2x2+7x+−3=0
Step 1: Use quadratic formula with a=2, b=7, c=-3.
x=
−b±√b2−4ac
