Erin gets her exercise by running. The graph shows the distances she covers in a given amount of time. How many hours does it ta
soldi70 [24.7K]

The correct answer is  c. 2 \frac{1}{2} hours

Explanation:

The graphic shows the relationship between the distance Erin covers by running and the time this requires. Additionally, to know the specific time that takes for Erin to run a specific distance or vice versa it is necessary to observe at which point the two variables intersect in the line of the graph.

According to this, Erin runs 25 miles (y-axis) in 2.5 hours (x-axis), which you can know because in the line shown by the graph the distance 25 miles that is in the middle of 20 and 30 miles intersects with 2.5 hours or the middle between 2 and 3. Additionally, this number can be expressed as 2 and a half hours, 2.5 or even 2 \frac{1}{2} hours because the fraction represents half. This makes option C the answer.

In the interval 0 x 360 find the values of x for which cos x =0.7252
Sergeeva-Olga [200]

Answer:

x_1 = 43.5145\°

x_2 = 316.4855\°

Step-by-step explanation:

We have a positive value for the cosine of x, so we know that the value of x should be in the first quadrant (0 ≤ x ≤ 90) or in the fourth quadrant (270 ≤ x ≤ 360).

Now, let's find the value of x that gives cos(x) = 0.7252 using the inverse function of the cosine, that is, the arc cosine function.

The value of x can be calculated using:

x = arccos(0.7252)

Using this function in a calculator (you may find it as: cos^{-1}(x)), we have that:

x_1 = 43.5145\°

So this is the value of x in the first quadrant. To find the other value of x, in the fourth quadrant, that gives the same result, we just need to calculate 360° minus the value we found:

x_2 = 360\° - 43.5145\° = 316.4855\°

So the values of x are:

x_1 = 43.5145\°

x_2 = 316.4855\°
