A² = b² + c² - 2bcCos A
a² = 11² + 13² - 2(11)(13)Cos(108)
a² = 378.38
a = √378.38
a = 19.45
Answer: 19.45
Answer:
Perimeter of a rectangle = 2(L + W)
Step-by-step explanation:
L = length
W = width
In a rectangle, of the four sides, there are two equal length and 2 equal width
Length = 2 sides
Width = 2 sides
perimeter of a rectangle is the sum of the lenths of its four sides.
Perimeter of a rectangle = L + L + W + W
= 2L + 2W
Factorize
= 2(L + W)
Perimeter of a rectangle = 2(L + W)
This expression shows the relationship
Using continuity concepts, it is found that the correct options are:
- The function is continuous at x = -4.
- The function has an infinite discontinuity at x = -1.
-----------------------------
A function f(x) is continuous at x = a if:

-----------------------------
- At x = -4, there are no changes in the definition of the function, thus, it is continuous.
- At x = -1, we have that:


- A different definition depending on the which side of -1 the function is, thus, it is a jump discontinuity.
