Answer:
y-intercept = -5, slope = 5/3
Step-by-step explanation:
The y-intercept is where on the y-axis (vertical line) does the graph cross. The slope can be found many different ways. My method for this graph was simply counting up the graph until I got to the point where the graph crosses another whole number on the x-axis and then counted over. This makes sense because slope is rise over run so if you go up 5 (from the y-intercept) and then over 3 (to get to the next whole number point) then your slope is 5/3
Answer:
The height of the tree is
18.67
feet
Step-by-step explanation:
Explanation:
The pole and the tree both cast shadows. The triangles which form are similar triangles, because the sun is shining from the same angle in the sky.
You can write this as a direct proportion. (height : shadow)
