We start with 80 and we add 1 on the first day, 2 on the 2nd, 4 on the 3rd, etc..
Looking at the numbers being added
1 = 20
2 = 21
4 = 22
8 = 23
16 = 24

We start with 80 and we add 2n to it where n represents the number of days into the iteration
with n starting at 0
The function that shows how many stamps we have on any given day is
D
S = 80 + ∑ 2n Where D is the number of days we are into the iteration
n=0
NOTE: This starts at day 0 which would be S = 80 + 20 = 80 + 1 = 81 stamps
Example: To find how many stamps we have on D = 4 we would have
S = 80+20+21+22+23+24
= 80+1+2+4+ 8+16
= 111 stamps

The surface area of the prism according to the segment labels is; 480mm².
<h3>What is the surface area of the prism?</h3>
The prism given in the task content is five-faced and hence, its surface area can be evaluated as follows;
Surface area = 2(0.5×15×8)+(15×9)+(8×9) + (17×9).
Hence, the surface area of the prism upon evaluation is; 480mm².

Answer:
pi
Step-by-step explanation:
to convert angles to radians you must multiply the angle measurement by the formula pi/180
180 x pi/180
the 180s cancel out and you are left with pi
