Answer:
18 square units
Step-by-step explanation:
To find the area of a rectangle, we just need the length and height.
3 vertices of a rectangle are given, which is enough here to figure out the length (x-axis distance) and the height (y-axis distance).
From (0,0) origin to (3,0) would be 3 - 0 = 3 units in the x-axis. That is length:
Length = 3 units
Now, a point is given (0,6), that is in the y-axis. This is from origin. So, the height is:
6 - 0 = 6 units
Height = 6
Now, the area would be:
Area = Length * Height
Area = 3 * 6
Area = 18 square units
Answer:
67.3°C
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt
So first we want to know how much mail he delivered in one month
8520/12 = 710 mails per month
there are 12 months, so we divide by 12 to find for one month
The answer we divide by two to find for 2 months.
710 times 2 = 1420 mails per 2 months.
