101
Step-by-step explanation:
Answer:
About 5043.58
Step-by-step explanation:
The standard form for an exponential decay after t time is:

Where a is the initial value, r is the rate decay, t is the time that has passed, and d is the amount of time it takes for 1 cycle.
The initial value is 9800. So a = 9800.
The quantity cuts in half. So, r = 1/2.
And it cuts in half every 6 days. For this question, we will convert this to hours. 6 days = 144 hours. So, we can let d = 144, where t will be in hours.
Therefore, our function is:

Where t is the amount of time that has passed, in hours.
Then the quantity left after 138 hours will be:

Answer:
64x⁶ - 216y³
Step-by-step explanation:
The formula for the volume of a cube is
Vol. = l³
For the large cube,
V =(4x²)³
V = 64x⁶
For the small cube,
v =(6y)³
v = 216y³
The difference in volume is
Diff. = 64x⁶ - 216y³
Answer:
1. 35 2. 565.5 3. 12.28
Step-by-step explanation:
1. Triangle 1 & 2: 7x3=21
You do not have to divide by 2 is since there are two triangles.
Semi-circle: 14.13
2. Trinagle: 29x19/2 = 275.5
Rectangle: 29x10 = 290
3. Triangle: 3x4/2 = 6
Semi-circle: 3.14x4/2 = 6.28
