3) 3.sec² Ф = 4.tan² Ф
but sec² Ф = 1/cos² Ф
3/cos² Ф = 4.tan² Ф
3/4 = (tan² Ф).(cos² Ф) ; tan² Ф = sin² Ф/cos² Ф
3/4 = (sin² Ф)x(cos² Ф)/(cos² Ф)
sin² Ф = 3/4
a) sin Ф = +(√3)/2 and b) sin Ф = - (√3)/2
sin Ф = + - (√3)/2 → Ф =π/3 + kπ/3
Refer to the attachment for the graph of the two functions in Desmos. To solve for the solution, we just equate the two functions and solve for x:



For the y value we just substitute x in any of the function:
ANSWER: The solution to the equation f(x)=g(x) is (

,

).
Answer:
41.7
Step-by-step explanation:

Answer:
v=5040
Step-by-step explanation:
84010=v60
(840)*(60)=v*(10)
50400=10v
Step 2: Flip the equation.
10v=50400
Step 3: Divide both sides by 10.
10v10=5040010
v=5040
It's a right triangle with both legs equal to 8 therefore
x²+x²=8²
2x²=64
x²=32
x=√32
x=2√2
