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:
Perimeter of the other polygon is 88 feet.
Step-by-step explanation:
We are given that, 'Two polygons are similar'.
Also, the perimeter of the smaller polygon is 66 feet and the ratio of the corresponding side lengths is 
.
As, we know,
'If two polygons are similar, the ratio of their perimeters is equal to the ratio of their side lengths'.
Thus, we have,
Let, the perimeter of the other polygon = x feet.
i.e. 
i.e. 
i.e. x= 88 feet
Thus, the perimeter of the other polygon is 88 feet.
B because the value is x has to be more the 2.5 and less then 6.5 at least because if you estimate the length of the missing part you would get 6.5 - 2.5 = 4
Answer:
The answers are 0, -6, 6
Step-by-step explanation:
So we have the equation:
6x(x^2 - 36) = 0
Multiply 36 x 6(the outside number)
6x(x^2 - 216)
Add x and x^2
6x^3 - 216 = 0
Now lets get rid of the exponents.
Split -216 into two equations. 6 x -6 = -216.
So the equations we have are:
(x + 6) and (x - 6)
Put this together with the 6x we have:
6x(x + 6)(x - 6) = 0
Now separate them into three problems:
6x = 0, x + 6 = 0, x - 6 = 0
Find x for all of them.
The answers are 0,-6, and 6.
Btw this is what I think you meant by solving it. If I got the wrong idea, let me know and I’ll fix it.
