Answer
C. (5/2, -1/3)
Step by step explanation
Here we use the rational root theorem.
The possible roots are
+1, +3, +5, +15, +1/2, +3/2, +5/2, +15/2, +1/3, +5/3, +1/6 and +5/6
We have to use the synthetic division to find the correct root of this function.
Here the roots are 5/2 and -1/3
Others are not roots of this function.
Let's check x = 5/2 with synthetic division.
5/2) 6 -13 13 -39 -15
- 15 5 45 15
--------------------------
6 2 18 6 0
Similarly x = -1/3 is also root of this function.
Answer: C. (5/2, -1/3)
Answer To (b): 10 sandwiches in 20 minutes. But If Your Friend Arrived 10 Minutes Earlier, Then He Can Make 20 Sandwiches In The 20 Minutes That You Are There. If He Started When He Arrived And The Twenty Minutes Started Then, You Can Only Make 5.
Answer:
<h2>The answer is option C</h2>
Step-by-step explanation:
![3( { \tan }^{2} \theta - { \sec }^{2} \theta)](https://tex.z-dn.net/?f=3%28%20%20%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%20-%20%20%20%20%7B%20%5Csec%20%7D%5E%7B2%7D%20%20%5Ctheta%29)
Using trigonometric identities
That's
![1 + { \tan }^{2} \theta = { \sec }^{2} \theta](https://tex.z-dn.net/?f=1%20%2B%20%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%20%20%3D%20%20%20%7B%20%5Csec%20%7D%5E%7B2%7D%20%20%5Ctheta)
Rewrite the expression
That's
![3({ \tan }^{2} \theta - (1 + { \tan }^{2} \theta)) \\](https://tex.z-dn.net/?f=3%28%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%20-%20%281%20%2B%20%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%29%29%20%5C%5C%20)
Simplify
We have
![3({ \tan }^{2} \theta - 1 - { \tan }^{2} \theta) \\ 3({ \tan }^{2} \theta - { \tan }^{2} \theta - 1)](https://tex.z-dn.net/?f=3%28%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%20-%201%20-%20%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%29%20%5C%5C%203%28%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%20-%20%7B%20%5Ctan%20%7D%5E%7B2%7D%20%5Ctheta%20-%201%29)
So we have
3( - 1)
We have the final answer as
<h2>- 3</h2>

Step-by-step explanation:
Eric will drive between 70 -4 = 66 mph and 70+4 = 74 mph. He will <em>not</em> drive less than 66 or more than 74 mph.
~Hello There!~
450/3 = 150
He would spend $150 each month
