Answer:
2.n=2.n+3
D.8=0.8 d=0
Step-by-step explanation:
Answer:
Step-by-step explanation:
ABCD is parallelogram. So, AB = CD = 5 ft
h (altitude) = 4 ft
Area = base * altitude = 5*4 = 20 square feet.
The point would be B since the distance says consistent from that point.
Answer:
a) k = 0.00012491389
b) The Shroud of Turin was 755 years old at the time of this data.
Step-by-step explanation:
(a) Find the value of the constant k in the differential equation C' = -kC.
First we find the differential equation, by separation of variables. So
So
In which K is the constant of integration, representing the initial amount of substance. So
Half-life of 5549 years.
This means that . We use this to find k. So
So
(b) In 1988 three teams of scientists found that the Shroud of Turin, which was reputed to be the burial cloth of Jesus, contained 91% of the amount of carbon-14 contained in freshly made cloth of the same material. How old was the Shroud of Turin at the time of this data?
This is t for which
So
The Shroud of Turin was 755 years old at the time of this data.
Well, so the x+5y= 0 you can make this into x=-5y and then plug this in into ( y=9-2x) the -2x , which these would become y=9-2(-5y) simplify and equals to y=9+10y. Then you simplify much smaller y=-9. Now that you have the y number you just plug this in into x=-5y, which these becomes x=-5(-9) and the answer is x=45. At the end you just need to find the x and y, so the answer is x=45 and y=-9 . Hopefully this would make this much easier to you.
