Graph the function defined by f(x)= |-x-7|
1 answer:
Answer: The answer is the third graph, attached herewith the image.
Step-by-step explanation: The given function is
We are to select the correct graph from the given four options that is defined by the function above.
At x = 0, y = 7
and
at y = -7, y = 0.
So, the points (0, 7) and (-7, 0) satisfies the given function and hence these points must lie on the graph also.
We can see that the points (0, 7) and (-7, 0) lie only on the third graph. The image is attached with these two points plotted.
Thus, the answer is the third graph.

Originally,
h = 20 m, the height of the tree trunk
d = 0.5 m, the diameter of the trunk
Because the density is 380 kg/m³, the mass of the trunk is
Answer: 1492.3 kg
After one year:
After the tree puts on a growth ring, the new diameter is
d = 0.5 + 2(4 x 10⁻³ m) = 0.508 m
The tree grows by 0.2 m, s the new height is
h = 20 + 0.2 = 20.2 m
The increase in volume is
Answer: The volume produced is 0.17 m³ (nearest hundredth)
