Suppose that sahil knows that 45 people with ages of 18 to 29 voted without using a calculator he quickly says then 135 people with ages of 30 to 49 voted is he correct how might sahil with his answer so quickly. Voters 18 to 29 are 10% and voters 30 to 49 are 30%

Three times the difference of federico’s age, and 4, increased by 7, is greater than 37. what are possible values of federico’s age?

Use the x-intercept method to find all real solutions of the equation.x^3-10x^2+27x-18=0

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
