Which statment explains how to round 4,826 to the nearest hundred? Round up to 4,900 because 8 > 5.

Round down to 4,800 because 2 <5.

Round up to 4.900 because 6 > 5.

Round up to 4.900 because 2 < 5.

4800

Step-by-step explanation:

you overcomplicated it. just see which one is closer. if it is over 50, you round up to 4900. if it is under 50 you round down to 4800.

same applies with numbers like 54 to the nearest 10. if its under 5 then round down, over 5 then round up.

where are the graphs?

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.
