Answer:
12
Step-by-step explanation:
4:6 = 2:3
2:3 times 7 equals 14:21
Hope this helped!
Answer:
D
Step-by-step explanation:
This is the concept of sequences and series. To solve the question we proceed as follows:
2] T=-4n-3
to get the 11th term we substitute n=11 in the expression and simplify. Thus, plugging in n=11 we obtain:
T=-4(11)-3
T=-44-3
T=-47
thus the 11th term is -47
3] General term is T=n²-1. The 7th term will be evaluated as above:
plug in n=7 in the expression and simplify:
T7=7²-1
T7=49-1
T7=48
thus the 11th term is 48
4] General sequence is T=1/3n². The term will be evaluated as follows:
plug in n=3 in the expression and simplify:
T3=1/(3×3²)=1/27
Thus the 3rd term is 1/27
Answer:
This is not a function.
Step-by-step explanation:
In a function, every x value corresponds with only one y value. In this relationship, the 6 corresponds with both 5 and 10, which is impossible in a function. Thus, it isn't a function.
