Answer:
2(11 + 6x)
Step-by-step explanation:
Answer:
Answer: a = 140°, b = 40° and c = 140°
Step-by-step explanation:
Angles a° and c° are also vertical angles, so must be equal, which means they are 140° each. Answer: a = 140°, b = 40° and c = 140°. Note: They are also called Vertically Opposite Angles, which is just a more exact way of saying the same thing.
Answer: The error of the diameter would be 5% .
Step-by-step explanation:
Since we have given that
Here, r is the radius
h is the height
So, it becomes,
So, we will derivate S wrt D, we get that
---------------------(1)
As we have given that
it will take to paint the side of the tank to within 5% of the true amount.
So, it becomes,
---------------(2)
So, from (1) and (2) , we get that
Hence, the error of the diameter would be 5% .
The answer is choice C
------------------------------------------------
You start off with the first term being a1 = 3
Then you add on 3 to get to 6 as the second term
The next thing to do is add on -3, which is the same as subtracting 3, to get back to 3 once more.
This pattern continues on forever. To ensure you add on either +3 or -3 to the previous term, we add on the general term 3*(-1)^n
Overall, the nth term is found by a(n) = a(n-1) + 3*(-1)^n, which is what choice C shows. I'm assuming your teacher meant to write 3(-1)^n instead of 3(-1)n
