Answer:
14
Step-by-step explanation:
1/2bh is saying that the base times the height, halved is the area of the triangle.
so
we will do the base times the height
7x4=28
then we will halve it
28/2=14
the answer is 14
The correct answer is A.
lets discard the other options:
For B:
B is always positive, but f(x) is not, so B graph is not the answers
For C:
C is always positive too, so it cannot be the desire graph.
For D:
D is always negative, but we know that x exponent 3 is positive for all positive numbers,
The independent variable is time, which varies from 0 to 0.5, so domain = [0,0.5].
The distance travelled is the dependent variable, varying from 0 to (1/2)80=40 km. The range is therefore [0,40].
Note: in interval notation, a square bracket means that the value is included in the interval.
I think the answer would be 288, i hope this helps
