Answer:
The cotangent of the angle will be b/a
Step-by-step explanation:
Since the cotangent and tangent are reciprocals of each other and the tangent of the same angle is a/b where a and b are not zero,
then the cotangent will be the reciprocal of the value of the tangent
= 1 / (a/b)
= 1 x (b/a)
= b/a
A rectangle has two dimensions, width and length, and the area of it is their product.
since we know its area is 3x²-11x-4, then the two factors from that trinomial are the likely width and length, namely (3x + 1) (x - 4).
you can check them with FOIL.
Answer:
<h2>C. 8 + 3i</h2>
Step-by-step explanation:
(9 + 6i) - (1 + 3i) = 9 + 6i - 1 - 3i = (9 - 1) + (6i - 3i) = 8 + 3i
I think the answer is 5 because you add the 1/2 and the other 1/2 leave the for alone that will give you 5
Example: 1/2+1/2=1+4=5
Assuming we want to factor the formula to (x+3)(x+3), you want to have a +9 where there is a -4 now. So you must add 13.
