Which algebraic expression is a polynomial? 3m2n – startfraction 2 m over n endfraction + startfraction 1 over n endfraction startfraction 2 m n over 5 endfraction – startfraction startroot m endroot over 4 endfraction + 4m5 startfraction 4 m cubed over n squared endfraction – 3mn5 + startroot 8 endroot 7mn + startfraction 3 m over 2 endfraction + startfraction 5 n over 4 endfraction

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
