10.2 ft Ans.
We solve this using geometric series.
A1 = 12 ft
A2 = ?
A3 = 8.67ft
Now, for geomteric progression,


A2 = 10.2 ft
1) 3 groups
2) Animals that fly
3) 32 (? It’s blurry but the answer is the percentage in the blue part)
4) A cow would be classified in “animals that walk” and a whale would be classified in “animals that swim”
5) It would not be useful now because animals like frogs can do multiple things, in early stages it could swim but when it gets older it could live on land. (Sorry if 5 is not the best answer, but it’s how I’d answer it.)
Answer:
(a) [3 -12 15 -21]
Step-by-step explanation:
Given;
3.[ 1 -4 5 -7]
The product of the function is calculated as;
3.[ 1 -4 5 -7] = [1 x 3 -4x3 5x3 -7x3]
= [3 -12 15 -21]
Therefore the correct option is "a" [3 -12 15 -21]
The answer would be d
Explanation: the second numbers are both the same, therefore they would be in the same line, and 7-1=6, leaving 6 units between them, I hope this helps :)
