Answer:
Step-by-step explanation:
y = 6x + 3 --------------(I)
x + 2y = 5 -------------(II)
substitute y = 6x + 3 in equation (II)
x + 2*(6x + 3) = 5
x + 2*6x + 2*3 = 5
x + 12x + 6 = 5
13x + 6 = 5
Base from the graph the intersection of the line is at 12 months. so this is the time where the cost of the two internet provider is equal. this can be solve by equating the two and solve for t.
<span>C(t) = 180 + 10t , C(t) = 25t
180 + 10t = 25t
180 = 25t - 10t
180 = 15t
t = 12

Answer:
The numerical value of the trigonometric function is 30 °
Step-by-step explanation:
Given trigonometric function as :
+
= 4
or, Taking LCM we get
= 4
Or, ( 1 + cos x )² + sin² x = 4 × ( sin x ) × ( 1 + cos x )
1 + cos² x + 2 cox + sin² x = 4 sin x + 4 sin x × cos x
or, ( cos² x + sin² x ) + ( 1 + 2 cos x ) = 4 sin x ( 1 + cos x )
∵ cos² x + sin² x = 1
or, 1 + 1 + 2 cos x = 4 sin x ( 1 + cos x )
or, 2 + 2 cos x = 4 sin x ( 1 + cos x )
or, 2 ( 1 + cos x ) = 4 sin x ( 1 + cos x )
Or,
= sin x
Or, sin x = 
∴ x = 
∵ sin 30 ° = 
I.e x = 30 °
Hence The numerical value of the trigonometric function is 30 ° answer
