Answer:
the answer is 59048
Step-by-step explanation:
as the common ratio is multiplying by 3 and the first term is 1 so from the rule (Tn=ar(power n-1 ) )
so the 11th term is 1*3(power 11-1 ) equal 3 power 10 equal 59048
Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.
Answer:
1 1/22
Step-by-step explanation:
Factor 11 x^2 y^2 out of both the numerator and the denominator to get 2(11 x^2 y^2)/11x^2 y^2, which is clearly equal to 2.
