Answer: After 18.05 minutes, the temperature of steel becomes 100 degrees.
Step-by-step explanation:
Since we have given that
Initial temperature = 2500
At t = 0,
we get that
After 2 minutes, the temperature of the steel is 1500 degrees.
so, it becomes,
So, We need to find the number of minutes when the temperature of steel would be 100 degrees.
So, it becomes,
Hence, after 18.05 minutes, the temperature of steel becomes 100 degrees.
Answer:
+3, +1
I think this is the answer because if its asking about the chart it is adding 3 on the x-axis and adding 1 on the y-axis
Hope this helps :)
The perimeter of a rectangle is twice the length plus twice the width. Thus,
2w + 2l = 36.
2l = 36 - 2w
l = 18 - w
The area is length times width.
36 = lw
36 = (18 - w)w
36 = 18w - w^2
w^2 - 18w + 36 = 0
w = (18 +- sqrt(18^2 - 4 * 36))/2
w = (18 +- sqrt(180))/2
w = 9 +- sqrt(45)
Thus, one of the side lengths is 9 + sqrt(45), and the other is 9 - sqrt(45).
Points are: 0, -3 and 1.5, 0
Yes it contains 3 terms
I hope this helps, good luck! :)
