Answer:
B
Step-by-step explanation:
The "value" of a function is the y-value.
Since we want negative y values, we look at "WHERE" the function is "UNDER" the y-axis.
Looking closely, it looks that function (the dip) is from x = -1 to x = 3
Hence, the function is negative at the interval -1 ≤ x ≤ 3
B is correct.
Answer:
117.53 feet^2
Step-by-step explanation:
So to start off we need to find the area of the pentagon.
The formula for the area of a pentagon is weird so I’m not going to write it but you can search it up.
So the area would be 27.53 inches^2.
Now for the triangles.
There is 5 triangles in total with a base of 4 and a height of 9.
So the area of one is base*height divided by two.
So it would be 18.
Now we can just multiply 18 by 5 which is 90 feet^2.
So when we add up 90 and 27.53 we get 117.53 feet^2.
