Answer:
b. They are at a speed of 30 mph when time begins.
Step-by-step explanation:
The y-axis represents time zero, when time begins. The curve intercepts the y-axis at y=30. Y-values on the graph represent speed in miles per hour (mph), so a y-value of 30 at the point on the y-axis represents ...
a speed of 30 mph when time begins
Answer:
It is by definition. 210 means 21 tens or 21 * 10. 30 means 3 tens or 3*10.
Since there is a ten on the top and bottom of the divisor 210/30 is also the same thing as 21/3. All of which is 7 and all of which is true by definition.

Given the distance of a point on ground (say P) from the bae of a tree (say XY) = 55 feet.
Given the angle from ground level (point P) to the top of the tree (X) = 34°
Let's assume the height of tree (XY) = 'h' feet.
We have a Right triangle ΔXYP where ∡Y=90° and YP = 55 feet.
Using Trigonometric ratios in right triangle ΔXYP:-
Tan (34°) = 

h = 55 × 0.6745 = 37.0979 feet
So, height of the tree = 37.1 feet.
