Answer:
a.
b. 26 meters
c. picture attached
Step-by-step explanation:
- Since the turtle travels 2.0 meters per minute, it will travel a total distance of in
minutes. We know that the total distance is
, so we can equate both total distances to create our rule:
- To find the distance of the turtle after 13 minutes we just need to replace with 13 in our rule:
The turtle cover a distance of 26 meters after 13 minutes.
- To graph the function we are going to evaluate our function at two points, and then we are joining those two points with a line (check the attached picture)
We already know that the turtle cover a distance of 26 meters after 13 minutes, since the distance depends on the time our point will have coordinates (time, distance) (13 minutes, 26 meters) (13, 26)
Notice that when time is zero, distance is zero as well, so our second point is (0, 0)
Now we can join the points using a line:

Answer:
The arc measure, x, that the satellite can see is 160°
Step-by-step explanation:
Given that the two tangents intersect at a point outside the with circle center O
The angle formed between between the two tangent = 20°
The first arc formed is measured as x°, which is the arc opposite the point where the two tangents meet = The arc the satellite can see
The angle x is given by the relationship;
x = 2 × (90 - v/2)
Where;
v = The angle formed at the point where the two tangent meet = 20°
Therefore;
x = 2 × (90 - 20/2) = 2 × (90 - 10) = 2 × 80 = 160°
The arc measure, x, that the satellite can see = 160°.
