Answer:
10, 1, 0.1, 0.01
It is a geometric sequence
Step-by-step explanation:
A(n + 1) = A(n) ÷ 10 for n ≥ 1 and A(1) = 10
A(1+1) = A(2) = A(1) / 10 = 10 / 10 = 1
A(2+1) = A(3) = A(2) / 10 = 1 / 10 = 0.1
A(3+1) = A(4) = A(3) / 10 = 0.1 / 10 = 0.01
It corresponds to a geometric sequence, which is defined by its starting number a (10), the common factor r (0.1) and the number of terms S.
I agree because he calculated it the right way and that is the same answer I got.
Hope I helped :)
So this is a two step process, first you must find the area of the rectangle, then find the area of the semicircle.
So to find the area of a rectangle, you use: Length*Height=Area
In this case that would be: 7*2=14cm
Next you find the area of the semicircle, to do this you first find the area of the circle (Pi*r^2) then divide it by 2.
The diameter of the circle is 4 because: 7-2-1=4cm
Next divide that by 2 so that you get the radius: 4/2=2cm
Not you can plug that into the equation to get the area of the circle: Pi*2^2<span>≈13cm^2
Next divide it by 2 so that you get the area of the semicircle:13/2</span><span><span>≈</span>6cm^2
At this point you can add the area of the semicircle to the area of the rectangle: 14+6=20cm^2
So your final answer is 20cm^2!

Use the compound amount formula:
A = P*(1+r/n)^(nt)
Here,
A = $3500*(1+0.0375/12)^(12*12) = $5485.24
