√72 = √4 * √18 = 2√18. Therefore her answer is incorrect.
√72 = √4 * √9 * √2 = 6√2.
Since √2 is approximately 1.41,
6 * 1.41 = 8.46 = 8.5 (nearest tenth).
Answer:
3rd Option and 4th Option
Step-by-step explanation:
Note: The options to the question is attached as picture below
<u>1st case</u>
Initial deposit (P) = 500
Annual interest rare (r) = 2.5%
Account balance after x years, y = P(1+r/100)×
y = 500(1+2.5/100)×
y = 500(1+0.025)×
y = 500(1.025)× ----- 3rd option
<u>2nd case</u>
Initial deposit (P) = 400
Annual interest rare (r) = 2%
Account balance after x years, y = P(1+r/100)×
y = 400(1+2/100)×
y = 400(1+0.02)×
y = 400(1.02)× ---- 4th option
77 points per year, 2,002 divided by 26 is 77.
√36/16 is the rational number. Mark brainliest please
