What’s the surface Area

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?

Identify this conic section. x2 - y2 = 16 o line circle ellipse parabola hyperbola

Yvaries directly as x. y =90 when x=6. find y when x=13
