The value of 
in the first quadrant is approximately 0.173.
There are 4 quadrants inside the cartesian aircraft. All trigonometric ratios of sin, cos, tan are high quality inside the first quadrant.in the 2nd quadrant simplest sin is advantageous rest are negative. within the 1/3 quadrant simplest tan is wonderful inside the fourth quadrant best cos is fantastic.
Given 
and 
is in the first quadrant.
We know from trigonometrical identities that
Substituting the value of 
in the above equation we get:
As lies in the first quadrant then the value of 
is positive.
∴
From the properties of trigonometry we know that :
The value of is approximately 0.173 to the nearest thousandth . The value is positive as the angle lies in the first quadrant.

Answer:
5th term of sequence = -18
nth term of the sequence = -5n + 7
Step-by-step explanation:
Difference between successive and previous term of the output,
= -3 - 2
= -5
Similarly, 
= -5
There is a common difference 'd' = (-5)
Therefore, the sequence formed will be an arithmetic sequence.
First term of the sequence 'a' = 2
Explicit formula of an arithmetic sequence, 
= a + (n - 1)d [n = input value]
= 2 + (n - 1)(-5)
= 2 - 5n + 5
= -5n + 7
5th term of this sequence,
= 2 - 20
= -18
Therefore, 5th term of sequence = -18
nth term of the sequence = -5n + 7
Surface area: S
radius: r
diameter: e
time: t
[dS/dt] = [dS/de]*[de/dt] => de/dt = [dS/dt] / [dS/de]
S = 4pi*r^2 = 4p*i(e/2)^2 = pi*e^2 => dS/de =2pi*e
dS/dt = 7cm^2 / min
de / dt = [2pi*e] / [7cm^2/min] =[7cm^2/min] / [2pi*10cm] = 0.11 cm/min
Answer:
An equilateral triangle is never similar to a scalene triangle, because you can never map one onto the other using only dilations and using rigid transformations
Step-by-step explanation:
