Answer:
Step-by-step explanation:
(a - b)(a +b) = a² - b²
1 - Sin² A = Cos² A

2) Sec² A - Tan² A = 1

3) LHS = Cosec² A + Cot² A
= Cosec² A + Cosec² A - 1
= 2Cosec² A - 1 = RHS

10/19. 40/4=10, and 56/4=19. therefore the answer is 10/19.
Answer:
Step-by-step explanation:
(1-4)/(2+3)= -3/5 is the slope
y - 4 = -3/5(x + 3)
the solution is F
The equation for the circumference is 2*pi*radius
if you are given the circumference then divide both sides by pi
that is because the diameter is 2 times the radius
so you can rearrange the equation to
C = pi * 2 * r
C = pi * d
divide both sides by pi
C/pi = d
Hope this helps :)
The phase shift is 7.2 right
