Answer:
B. A cow of 5 years is predicted to produce 5.5 more gallons per week.
Step-by-step explanation:
Let , where is the age of the dairy cow, measured in years, and is the predicted milk production, measured in gallons per week.
Besides, we consider and , such that , we define the difference between predicted milk productions () below:
(1)
If we know that and , then the difference between predicted milk productions is:
That is, a cow of 5 years is predicted to produce 5.5 more gallons per week than a cow of 10 years. Hence, the right answer is B.
First, start out by inserting the numbers:
3.14(4(2) (4^2) + 4(2)
Next, multiply the given numbers:
3.14(8 (4^2) + 8)
Then, multiply 4^2 (since the exponent is 2, multiply 4 two times: 4 * 4):
3.14(8 (16) + 8)
Now, multiply the first 8 to 16:
3.14(128 + 8)
Use the distributive property to solve this next one:
401.92 + 25.12
Finally, add up you two decimals:
427.04
You should get 427.04 (I could be wrong though).
Hopefully that helped! :)
