Answer:
Step-by-step explanation:
hello :
note :
for all x in ℝ : 1) sin(x+2kπ) = sinx ...k in Z 2) sin(-x) = -sinx
in this exercice :
sin(-4π-x)= sin(-x) = -sinx because : -4π = 2(-2)π (form : 2kπ when : k=-2)
Step-by-step explanation:
I'm going to assume you mean
which can be rewritten as since if you start with since when you do (10^x)^c you're just multiplying the exponent which is represented by the x but is equal to the log you just multiply the log which is why you can bring it in front.
You can then approximate the value of log(5) using a calculator and multiply by 125 to get around 87.371
Answer:
there are no real solutions to the system
Answer:
25 mins
Step-by-step explanation:
Harpeet worked -- x mins
Aiysha worked -- 2x mins
If Aiysha worked 50 mins, Harpeet worked:
2x = 50
x = 25 mins
Thenks and mark me brainliest :))
