We are asked in the problem to find csc (13pi/6). first we can convert the radians angle first to degrees that is equal to 390 degrees. The terminal angle is 30 degrees. csc is the reverse of sin. sin 30 is equal to 1/2, positive since in the first quadrant. hence the answer is 2.
The answer to this problem is 50
Answer:
The answer is 150 units squared.
Step-by-step explanation:
Answer:
5^3*5^-7 = 1/5^4 b. is true = 625
5^3*5^-7 = 5^-4 c. is true = 625
Step-by-step explanation:
b. Left hand side
Simplify the following:
5^3/5^7
Combine powers. 5^3/5^7 = 5^(3 - 7):
5^(3 - 7)
3 - 7 = -4:
5^(-4)
5^4 = (5^2)^2:
1/(5^2)^2
5^2 = 25:
