Answer:
B
Step-by-step explanation:
The range is the set of y-values for which the function is defined.
** Attached is the graph of the function
By looking at the graph, we can clearly see that there aren't any y-values that is not permitted in the graph. The function is defined for all y-values. Hence the range is set of all real numbers, or, the range is (-∞, +∞)
Answer choice B is right.
Answer:
{-7, 2, 8}
Step-by-step explanation:
We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.
So our equation is:
y = 3x + 2
Then we substitute for the x-values:
y = 3(-3) + 2
y = -9 + 2
y = -7
y = 3(0) + 2
y = 0 + 2
y = 2
y = 3(2) + 2
y = 6 + 2
y = 8
So our range would be {-7, 2, 8}.
You do 2.5×50 and that would give you your answer which is 125 ft long
Divide the figure into two parts, a triangle and a square
TRIANGLE
the base (b) = 5 cm
the height (h) = 4 cm
Calculate the area of the triangle
a = 1/2 × b × h
a = 1/2 × 5 × 4
a = 20/2
a = 10
The area of the triangle is 10 cm²
SQUARE
the side (s) = 5 cm
Calculate the area of the square
a = s²
a = 5²
a = 25
The area of the square is 25 cm²
THE AREA OF THE FIGURE
a figure = a of triangle + a of square
a figure = 10 + 25
a figure = 35
The area of the figure is 35 cm²
