Answer:
Step-by-step explanation:
we know that
The figure show a parallelogram
Remember that
In a parallelogram opposites angles are congruent and consecutive angles are supplementary
so
we have
substitute
The answer is C.k = 1.4 / x :))

1. If the line that we are searching for is perpendicular to the line y = -4x, this means that the gradient of our line and the gradient of the perpendicular line will multiply to give -1. Thus if we call the gradient of our line m, then:
m*(-4) = -1
-4m = -1
m = 1/4
2. Since we know that m = 1/4 and we have a point (2,6) on our line, we can use the formula y - y1 = m(x - x1) to find the equation of our line, where (x1, y1) is the coordinates of a point on the line. Thus:
y - y1 = m(x - x1)
y - 6 = (1/4)(x - 2)
y - 6 = (1/4)x - 2/4 (Expand (1/4)(x - 2))
y = (1/4)x - 1/2 + 6 (Simplify 2/4 and add 6 to each side)
y = (1/4)x + 11/2 (Evaluate -1/2 + 6)
Slope-intercept form is given by y = mx + c. As our equation is already in this form, there is nothing more to do. Thus, the answer is y = (1/4)x + 11/2
Given the equation :
Let: y = sin x
So,
the given equation will be:
Solve for y, take 3y as a common:
so,
Note: the range of sine function is [ -1, 1]
So, sin x = 2 ( is rejected)
So, the answer will be: x ={ 0 , pi }
