Answer:
a) cannot be determined
b) a triangle can be drawn, but its dimensions cannot be determined
Step-by-step explanation:
<h3>a)</h3>
The vertical axis is labeled in units of kilometers. The horizontal axis is labeled as distance, with no units given. The line shown appears to descend from 12 units above ground level over a distance of 34 units along ground level. One could argue the slope is 12/34 = 6/17, but there is no indication the horizontal units are the same as the vertical units.
The slope of the graph cannot be determined, because we don't know the horizontal units.
__
<h3>b)</h3>
You can draw the triangle, but you cannot determine its dimensions.
Answer:
693 Years
Step-by-step explanation:
Given an initial amount and k (a negative constant) determined by the nature of the material, the amount of radioactive material remaining at a given time t, is determined using he formula:
If a certain radioactive isotope decays at a rate of 0.1% annually.
The half-life of the isotope is 693 years.
