5.2 is irrational cause the .222 keeps going
Answer:
b)
Step-by-step explanation:
The line with positive slope is 3x-5y≥15 and the line with negative slope is 2x+3y≤12.
This is because such inequalities represent half planes which are divided by the corresponding lines.
Put (0,0) in both lines to check if the origin lies in the shaded half plane or not.
Sec∅ = 1/cos∅
= 1/cos(240)
= 1/cos(180 + 60)
= 1/-cos(60)
= 1/(-1/2)
= -2

Answer:
the appropriate choice is the last one
Step-by-step explanation:
![7^{\frac{4}{5}}=(7^4)^{\frac{1}{5}}=\sqrt[5]{7^4}](https://tex.z-dn.net/?f=7%5E%7B%5Cfrac%7B4%7D%7B5%7D%7D%3D%287%5E4%29%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D%3D%5Csqrt%5B5%5D%7B7%5E4%7D)
This is equivalent to b^(pq) with b=7, p=4, q=1/5. Here, q is a rational number, as suggested by the last answer choice.
