Hi, thank you for posting your question here at Brainly. Whatever the sequence is, the important thing is to follow the explicit rule. The n denoted in the equation must pertain to the 12th term. Hence,
A12 = -16 + 2(12)
A12 = 8
The 12th term is 8. I hope I was able to help. Have a good day.
Note: Consider the side of first triangle is TQ instead of TA.
Given:
Triangles TQM and TPN which share vertex T.
To find:
The theorem which shows that .
Solution:
In triangle TQM and TPN,
[Given]
[Given]
[Given]
Since two sides and their including angle are congruent in both triangles, therefore both triangles are congruent by SAS postulate.
[SAS]
Therefore, the correct option is C.
-1 + 6x = - 2 |add 1 to both sides
6x = -1 |divide both sides by 6
x = - 1/6
Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of 5000 dollars needed for college.
Step-by-step explanation: Im not good with equations but here we go.
First: AS we know the account already had 2,500, and every month she deposits 50$.
What we can do is to divide 2,500 divided by 50 which will be 50.
tis a little of plain differentiation.
we know the radius of the cone is decreasing at 10 mtr/mins, or namely dr/dt = -10, decreasing, meaning is negative.
we know the volume is decreasing at a rate of 1346 mtr/mins or namely dV/dt = -1346, also negative.
so, when h = 9 and V = 307, what is dh/dt in essence.
we'll be needing the "r" value at that instant, so let's get it
now let's get the derivative of the volume of the cone
