B
Step-by-step explanation:
the negative on the outside makes it a reflection over the x-axis
Answer:
Step-by-step explanation:
Area of a circle is pi r squared.
So 3.142 times the radius squared.
They gave you the diameter(d), that's the distance all the way across. You need the radius(r), which is one half of the diameter. 7 divided by 2.
3.142X3.5squared=
Well, 3.5 squared is 3.5X3.5=12.25
So, then 3.142X12.25=38.4895
Now, we round. Second decimal place is an eight, followed by a nine. Five or above means round up.
38.49

<u>We are given:</u>
Speed of the train = 90 km/h
<u>Converting the speed to km per minute:</u>
<u></u>
[since 1 hour = 60 minutes, h/60 minutes is equal to 1]
The 'h' in numerator and denominator will cancel out
90km / 60 min
1.5 km/min
<u>Distance travelled in 2 minutes:</u>
Distance = Speed * time
Distance = ![1.5\frac{km}{min}* 2 min](https://tex.z-dn.net/?f=1.5%5Cfrac%7Bkm%7D%7Bmin%7D%2A%202%20min)
Distance = 3 km
Answer:
Part 1)
Part 2)
Part 3)
Part 4) In the procedure
Step-by-step explanation:
Part 1) we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
i is the interest rate in decimal
n is number of years
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Applying log both sides
Part 2)
in this problem we have
substitute in the formula above
Part 3) in this problem we have
substitute in the formula above
The money is not enough
Part 4)
I would personally increase the investment from 2,200 dollars so that it grows to 2,500 dollars at the time I want to make the trip, for example if I wanted to make the trip in two years, I would increase the initial investment from 2200 dollars to 2427 dollars.
