In ΔXYZ, the measure of ∠Z=90°, the measure of ∠X=73°, and YZ = 75 feet. Find the length of ZX to the nearest tenth of a foot.

Find the sum of the first 8 terms of the following sequence. round to the nearest hundredth if necessary.

Lassify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f(x) = (3x + 2)(−6x − 3) linear function; linear term: −21x; constant term: −6 linear function; linear term: −18x2; constant term: −6 quadratic function; quadratic term: 6x2; linear term: 24x; constant term: −6 quadratic function; quadratic term: −18x2; linear term: −21x; constant term: −6

How to do this , and can some one explain
