Answer:
the largest angle of the field is 149⁰
Step-by-step explanation:
Given;
perimeter of the triangular filed, P = 120 m
length of two known sides, a and b = 21 m and 40 m respectively
The length of the third side is calculated as follows;
a + b + c = P
21 m + 40 m + c = 120 m
61 m + c = 120 m
c = 120 m - 61 m
c = 59 m

Consider ABC as the triangular field;
Angle A is calculated by applying cosine rule;
Angle B is calculated as follows;
Angle C is calculated as follows;
Therefore, the largest angle of the field is 149⁰.
Answer:
Step-by-step explanation:
From the question we are told that:
Function given
Co-ordinates
(x,y)=[1, 4]
Generally the second differentiation of function is mathematically given by
Therefore critical point
Generally the substitutions of co-ordinate into function is mathematically given by
For 1
For 4
For critical point 3
Therefore the maximum value of f(x) = –x2 + 6x over the interval [1, 4] is given by
