-1/45
Step-by-step explanation:
I did the equation okay hope this help!! <3
Answer:
No, it is not possible to obtain zero by adding two vectors of unequal magnitudes.
Explanation:
The Sum of two vectors can only be zero if they are equal in magnitude and opposite in direction. So no two vectors of unequal magnitude cannot be added to give a null vector. Three vectors of equal magnitude and making an angle 120 degrees with each other gives a zero resultant.
Answer:
∠ L ≈ 21.6°
Step-by-step explanation:
Using the Sine rule in the triangle
=
, that is
=
( cross- multiply )
42 × sinL = 34 × sin27° ( divide both sides by 42 )
sinL =
, then
∠ L =
(
) ≈ 21.6° ( to the nearest tenth )
Answer:

Step-by-step explanation:
Using the given identity, find the required value as per following steps:




P(x) that will be R(x) - C(x):
Note the use of parentheses! Without them we would not realize that both the 21 and the 98 should be subtracted.
Now that we have our profit function, we can see that:<span>Its graph will be a parabola because of the squared term.The parabola will open downward because of the negative coefficient, -2, in front of the squared term.The highest point (which would be the maximum profit) on the downward parabola would be the vertex of the parabola.</span>From the above we now know that we want to find the vertex of the profit parabola.
The x coordinate of the vertex of a parabola will be -b/2a where the "b" is the coefficient of the x term and the "a" is the coefficient of the x squared term. From p(x)= -2^2 + 34x-98
we can see that your "a" is -2 and your "b" is 34. So the x coordinate of the vertex (which is where the maximum profit is) will be: -34/-2=17
