Answer:
2.4 so B
Step-by-step explanation:
you will divide 11.40 by 4.75
A 'tangent' to a line means the derivative. You can differentiate the function as follows:


At a horizontal tangent, the derivative is equal to 0. So, let's set it equal to 0, and solve for x. Remember, whenever doing trigonometry in calculus, we assume we are answering in radians. So:



The values at which cos(x) equals -1 are π
, and then 3π, 5π and so on. You basically just keep adding 2π to the previous number and get the answer. So, this can be written as:

That will be your final answer. You could write this as an infinite series, but I just didn't want to complicate it. So, if you want one, I can give you one.
Answer:
Step-by-step explanation:
Coordinates of B is (3,-4)
You multiply -2 by 2 to get -4 and then create the equation then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)
You multiply -1 by 2 to get -2 and then create the equation then you subtract 2 by -2 which gives you -4 (y coordinate of B)
To check your answer use the midpoint formula
which will give you the midpoint (-2,-1)
The first one
Arithmetic sequence formula is a1 + (n - 1)d
Where a1 is the first term in the sequence, and d is the difference between the two terms.
Find the third term in the first sequence with the equation: 0 + (3 - 1)(4 - 2) = 2(2) = 4 ✅
Fourth term: 0 + (4 - 1)(6 - 4) = 3(2) = 6 ✅
The others don’t work because their differences are not consistent
