A
Step-by-step explanation:
test the constant 1/2 + (1/2)*(-3) = -2/2 = -1
Answer:
14.6
Step-by-step explanation:
It is given that,
The average weight of the top 5 fish caught at a fishing tournament was 12.3 pounds. From the attached figure, the weight of 5 fish are given. We need to find the weight of Wayne S. fish.
Average = sum of terms/no of terms
Let the weight of Wayne S. is x. So,
Here the sum of terms is x+12.8+12.6+11.8+9.7 and the number of terms is 5.

So, the weight of the heaviest fish is 14.6.
When two chords of a circle intercept, the products of the segments are equal, that is, PT*QT=RT*ST
6*4=RT*10
RT=2.4
