Answer:
a) 160 minutes per day
b) Find the graph attached
c) on 10th week Maria would be walking 2560 minutes per day
Step-by-step explanation:
Week 1 - 5 minutes per day
Week 2 - 10 minutes per day
Week 3 - 20 minutes per day
Week 4 - 40 minutes per day
Week 5 - 80 minutes per day
Week 6 - 160 minutes per day
a) 160 minutes per day
b) Find the graph attached
c) on 10th week Maria would be walking 2560 minutes per day
Answer:
= 
+ 6
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
- 11 - (- 17) = - 5 - (- 11) = 1 - (- 5) = 6
A recursive rule allows a term to be found by adding d to the previous term, thus
= + 6 with a₁ = - 17
Let me tell you a secret!
You know how the formula for Circumference is
<span>C = 2πr
</span>
Where r is the radius?
The reason why this formula works the way it does is because of what <span>π IS.
</span><span>π is the ratio of ANY circle's Circumference to it's Diameter.
So you can think of </span><span>π like this:
</span>
Circumference / Diameter.
2r is the same as the diameter. So what you are doing is canceling out the diameter. Similar to what you do in algebra I to solve for x. Then you are just left with the circumference. That's pretty neat!
So, let's get to it!
2<span>πr
</span>
Sadly, you'll most likely need to use a calculator for this problem, but if you are not permitted one then replace <span>π with 3.14.
</span>
What is r?
r = diameter / 2
r = 12 / 2
r = 6
2<span>π6
</span>
If you are allowed to use a calculator then plug it in to it. If not then start doing some long multiplication!
