It wont let me open it up :(
The answer:
the main rule:
for all value positive of a real b, √b²= b, and √b*c= √b * √c, if c is a real positive
let A=√25x^4, we know that 25x^4=5² * x² * x²
therefore,
√25x^4= √5² * x² * x² =√5² √x² √x² = 5* x*x= 5x²
the final answer is A=√25x^4=5x²
It is C because u have to do some stuff and find out
Answer:
AC =4DB
Step-by-step explanation:
D is midpoint of AB .So, AD = DB
AB = 2DB ---------- (i)
B is the midpoint of AC.So, AB = BC
AC = 2AB
= 2*2DB {FROM 1}
=4DB
The work you have done is correct.
Your period is 2pi/(pi/60) = 120
There is no horizontal shift.
