Answer:
See below.
Step-by-step explanation:
So, we have:
Recall that secant is simply the reciprocal of cosine. So we can:
Now, recall the unit circle. Since cosine is negative, it must be in Quadrants II and/or III. The numerator is the square root of 3. The denominator is 2. The whole thing is negative. Therefore, this means that 150 or 5π/6 is a candidate. Therefore, due to reference angles, 180+30=210 or 7π/6 is also a candidate.
Therefore, the possible values for theta is
5π/6 +2nπ
and
7π/6 + 2nπ
<h2>Answer:</h2>
a. is the correct option
<h2>Step-by-step explanation:</h2>The graph of a function and its inverse function
are related to each other. The relationship between these two graphs can be explained by taking a point
that is on the graph of
, then point
must lie on the graph
and vice versa meaning that the graph of
is a reflection of
in the line
. The only graph that meet this requirement is the option a. For instance, the point
is on the graph of
while the point
is on the graph of
as indicated below.
Answer:
This means that the family must travel for at least 4 days.
<em></em>
Step-by-step explanation:
Given
Required
Determine and solve the inequality
The number of days is represented with D
So:
On any D number of days, the family would have covered a distance of 350 * D miles
If the total distance is at least 1400, then the inequality is:
[The term "At least" is used to represent <em>greater than or equal to</em>]
Divide through by 350
<em>This means that the family must travel for at least 4 days.</em>
