Answer:
What is it rounded up to???
Step-by-step explanation:
Answer:
The values of x that satisfy the given equation are:
x1 = 1.183 + nπ
x2 = -1.183 + nπ
Step-by-step explanation:
Given tan²x - sin²x/sin²x = 5
Simplifying this, we have
tan²x - 1 = 5
Adding 1 to both sides, we have
tan²x = 6
Because tan²x = (tanx)², we can write as
(tanx)² = 6
Taking square roots of both sides, we have.
tanx = ±√6
x = arctan(±√6) + nπ
≈ 1.183 + nπ or -1.183 + nπ
The area of a trapezoid is given by
.. A = (b1 +b2)/2*h
.. = (13 cm +21 cm)/2*(6 cm)
.. = 102 cm^2 . . . . . . . . . . . . . . corresponds to selection A
6(x + 4) = 2(y + 5)..........Multiply everything out
6x + 24 = 2y + 10..........Solve for 2y by subtracting 10 from both sides
6x + 24 - 10 = 2y + 10 - 10
6x + 14 = 2y..................Solve for y by dividing both sides by 2
2y/2 = (6x + 14)/2
y = 3x + 7......................ANSWER.
