Answer:
C
Step-by-step explanation:
I hope i got it correct :)
If tan theta is -1, we know immediately that theta is in either Quadrant II or Q IV. We need to focus on Q IV due to the restrictions on theta.
Because tan theta is -1, the ray representing theta makes a 45 degree angle with the horiz axis, and a 45 degree angle with the negative vert. axis. Thus the hypotenuse, by the Pythagorean Theorem, tells us that the hyp is sqrt(2).
Thus, the cosine of theta is adj / hyp, or +1 / sqrt(2), or [sqrt(2)]/2
The secant of theta is the reciprocal of that, and thus is
2 sqrt(2)
---------- * ------------ = sqrt(2) (answer)
sqrt(2) sqrt(2)

Step-by-step explanation:
The question is incomplete. However, I'll ask and answer possible questions that emanate from the given parameter.
A possible question is: Write the given information as a function of distance.
We have that;



The function would be calculated as:
Base Distance + Rate * Time
Substitute values for Base Distance, Rate and Time
This gives:


Hence;

Another possible question is to determine the current distance travelled by the family at a rate of 80 miles per hour for 3 hours.
Here, we have:


Substitute these values in 



Answer: B
We all know that area= LxW
The width that is being shown is 8ft. The length is 20ft. Therefore, you multiply 8 x 20 which gives you 160ft squared. Hope this this helps :)
