Answer:
96 cm²
Step-by-step explanation:
Triangular face:
base = 8 cm
height = 6 cm
Area of triangle = 
Area of 4 triangular faces = 4 * 24 = 96 cm²
Answer:
The range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.
Step-by-step explanation:
We know that the set of values of the dependent variable for which a function is defined.
From the given function, we can easily observe that the graph is kind of oscillating between the y-value y = 5 and y = -9.
i.e.
at y = 5, the graph gets its maximum value
at y = -9, the graph gets its minimum value
Thus, the range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.
Answer:
(- 2, - 3) and (1, 0)
Step-by-step explanation:
The solution to a system of equations given graphically are at the points of intersection of the 2 graphs.
The solutions are therefore (- 2, - 3 ) and (1, 0 )
