Answer:
Step-by-step explanation:
B = { x, y } = { } , { x }, { y }, { x, y }
C = { 1, 2, 8 } = { } , { 1 }, { 2 }, { 8 }, { 1, 2 }, { 1, 8}, { 2, 8}, { 1, 2, 8}
. E = { a } ={ } , { a }
2. { }, {x}, {y}, {x,y}
3. { }, {1}, {2},{8},{1,2},{1,8},{2,8},{1,2,8}
4. { }, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,c,d}, {a,b,d}, {b,c,d}, {a,b,c,d}
5. { }, {a}
Answer:So, since it is continuously, we need to think of PERT
A=P\times e^{rt}
So, we just plug our numbers in to solve for T
8000=4000e^{.07t}\\\ln(8000)=\ln(4000e^{.07t})\\\ln(8000) = \ln(4000) + \ln(e^{.07t})\\\ln(8000)=\ln(4000)+.07t\ln(e)\\\ln(8000)=\ln(4000)+.07t\\\frac{\ln(8000)}{\ln(4000)}=.07t\\\frac{\ln(8000)}{.07\ln(4000)}=t\\ 15.479=t
It will take 15.479 years
The answer is A f(x)=-2x + 70
The original area of the rectangle is
<u>Explanation:</u>
width = x
length = x + 2
area of the rectangle = x (x+2)
length = x + 2 + 5 = x+7
Solving this equation, we get
x =5ft
So, original width = 5ft
original length = 5+2ft = 7ft
Thus, original area of the rectangle = 5 X 7ft =
Therefore, the original area of the rectangle is
