Answer:
Mₙ= 3*1.2⁽ⁿ⁻¹⁾
Step-by-step explanation:
week 1- 3 miles
week 2 - +20% ⇒ 3*1.2
week 3- +20% ⇒ 3*1.2*1.2
...
week n- +20% ⇒ 3*1.2⁽ⁿ⁻¹⁾
Mₙ= 3*1.2⁽ⁿ⁻¹⁾
Mₙ - miles on week n
-8a^8b^-2/10a^-4b^-10
= (-8/10) a^(8+4)b^(-2+10)
= -4/5 a^12 b^8
=-4 a^12 b^8 / 5
Answer is A.) -4 a^12 b^8 / 5
Answer:
5min
Step-by-step explanation:
First form yourself an equation, 113.2-10.8x ≤70
Now begin to work it out
*113.2-10.8(1) ≤70 (instead of x, put a number, this will be how many minutes
1~ 102.4 is not less than or equal to 70, so we repeat this process
2~ 91.9
3~81.1
4~70.3 this is not the answer because even though its at 70 there is still a .3 so we keep going,
5~59.5
59.5 is ≤ 70, so the answer is 5 minutes
P.S. don't believe me? that's okay, use the formula, plug in five to see for yourself
i hope this helps ;)
