Answer:
Step-by-step explanation:
Domain of a function is given by the set of x-values (Input values) on the graph.
Range of a function is given by the set of y-values (output values) on the graph.
From the graph attached,
Set of time will represent the "domain" and set of snowfall will represent the "range" of the function graphed.
a). Domain of the function: 0 ≤ x ≤ 5
b). Range of the function: 0 ≤ y ≤ 10

Answer:
47.6m.
Step by step solution:
Perimeter of a triangle = base + 2 . length____(1)
Area of a triangle = 1/2 . base . diagonal
108 = 1/2 . base . 15
multiplying both sides by 2:
216 = 15 . base
dividing both sides by 15:
base = 14.4m
But the diagonal divides the triangle into two
right angle triangles each with the same length (hypotenuse),base and diagonal(height).
Taking one right angle triangle:
And using pythagoras theorem;
length² = base² + diagonal ²
length² = 7.2² + 15²
Note: Base of each right angle triangle is 7.2 which would sum up to be 14.4 the base of the full triangle.
length² = 276.84
taking the square root of both sides:
length = 16.6m
Putting the values of the base and length into equation (1).
Perimeter of the triangle = 14.4 + 2 . 16.6
Note: We are dealing with the whole triangle
now hence the base is 14.4m.
Perimeter of the triangle = 14.4 + 33.2 = 47.6m.
Answer:
I believe its 17, this is a 90 degree angle, so 90-73=17
