At what x-values do the graphs of the functions y=cos 2x and y=1-sin^2x intersect over the interval 0 < x < pi
_ _

No solution.

Step-by-step explanation:

The given functions are

and .

To find the point of intersections of the graphs of the two functions: we equate them and solve for .

Recall the double angle identity;

Apply this identity to obtain;

if the interval is , then the two graphs intersect at

But does not belong to the open interval

No point of intersection.

answer: 10 meter

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
