Answer:
One of the simplest techniques to estimate an average grain size is the intercept technique. A random straight line is drawn though the micrograph. The number of grain boundaries intersecting the line are counted. The average grain size is found by dividing the number of intersections by the actual line length. Average grain size =1/(number of intersections/actual length of the line). where actual line length = measured length divided by magnification.
Answer:
answer is b with 17%
Step-by-step explanation:
convert the percents given to decimals then multiply it with 96$, whichever one gets 16$ is your answer. 0.17 x 96 = 16.32, round it equals to 16$
Answer:
f(x) = (x -3)^2·(x +7)^5·(x -4)
Step-by-step explanation:
When a polynomial (or any function) has a zero of "a" with multiplicity "b", then (x -a)^b is a factor. Your polynomial factors as ...
f(x) = (x -3)^2·(x +7)^5·(x -4)

<em>Comment on the graph</em>
When the zero has multiplicity 1, the function crosses the x-axis with a non-zero slope.
When a zero has even multiplicity, the graph touches the axis, but does not cross. The graph crosses the x-axis if the multiplicity of the zero is odd.
When the zero has multiplicity greater than 1, the point where the curve touches the x-axis has zero slope. The "flatness" at that point increases with increasing multiplicity.
