This is a big job i need help with Copy of 4.3 -4.5 Assessment Day 1

x = 3 ± √(5+y)

i will u if u answer my question in math

(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.

c and e

step-by-step explanation: c and e seem the most probable because a number less than 2 on a spinner with 4 equal sections would be 25% and e because all of the stacks contain 13 of that card.
