Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
Answer:
d =2
Step-by-step explanation:
6d+8=14+3d
Subtract 3d from each side
6d-3d+8=14+3d-3d
3d +8 = 14
Subtract 8 from each side
3d +8-8 = 14-8
3d =6
Divide by 3
3d/3 = 6/3
d =2
For this case, the first thing we should do is observe that we have a linear equation.
Therefore, we have a sequence of the form:

Where, k: is the slope of the line.
We have then:

Substituting we have:
Answer:
An explicit formula for the sequence of the number of bacterium is:
an = 21 * n
option 1
The price without Tax is 93.75% of $28.35 (100-6.25)
Which is $27,58
Tip is 20% of that which is $5,31
So total cost is 28.35+5.31= $33.66
