Answer:
3, 4, 5
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
We are given the expression,
On re-writing the expression after borrowing 1, we have,
=
i.e. =
i.e. =
Thus, the equivalent expression after borrowing 1 from the given expression is .
Hence, option A is correct.
Answer:
m = 3/2
Step-by-step explanation:
Use the slope formula: (y2 - y1) / (x2 - x1)
Answer:
30 degrees
Step-by-step explanation:
u dot v=1*4+1*4+1*4+0*4=4+4+4+0=12
|u|=sqrt(1^2+1^2+1^2+0^2)=sqrt(3)
|v|=sqrt(4^2+4^2+4^2+4^2)=sqrt(4*4^2)=2*4=8
cos(theta)=u dot v/(|u||v|)
cos(theta)=12/(sqrt(3)*8)
cos(theta)=3/(sqrt(3)*2)
cos(theta)=sqrt(3)/2
theta=30 degrees
