It’s a and c my good friend
Answer:

Step-by-step explanation:
From the question we are told that:
Function

Generally 1st derivative f'(x) of Fuction f(x) is


Generally 2nd derivative f''(x) of Fuction f(x) is
Where

Therefore



C = 180 - (22 + 105) = 180 - 127 = 53 degrees
Area of triangle = 1/2 ab sin C
But a / sin A = b / sin B or a = b sin A / sin B = (14 x sin 22) / sin 105 = 5.429
Therefore, Area of triangle = 1/2 x 5.429 x 14 x sin 53 = 30.4 units^2
Answer:

Step-by-step explanation:
Given


Required
Calculate the diameter
The area of a sector is:

Substitute values for Area and 

Divide both sides by 

Make
the subject



Take positive square roots of both sides



The diameter is then calculated as:



Answer:
b
Step-by-step explanation:
It is asking for the value of the green box.
The distance formula is given too.
Q = (0,-a)
P = (b, -c)
d = √(b - 0)² + (-c - (-a))²
d = √b² + (-c + a)²
