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.
Answer:
ummm, picture misssing, or it's just 25 i guess
Step-by-step explanation:
Longest is 6x^2+8
half of that is 3x^2+4
perimiter=sum of sides
so
6x^2+8+12x-3+3x^2+4=
9x^2+12+9
Answer:
ACB = 112°
Step-by-step explanation:
First form a sketch where will have a triangle sketch showing the points ABC with AB= 80km and CB = 56 km
Apply the law of cosine as;
c²=a²+b²-2ab*cos(C)
To get angle C;
C=arccos((a²+b²-c²)/(2ab))
Substitute values given in the equation as
C=arccos((40²+56²-80²)/(2*40*56))
C=arccos(-1664/4480)
C=112°
