Hi,
A)

B)
Only if n=4*k or n=4*k+1 , k beeing an integer.
Answer:
Step-by-step explanation:
Factor
x^2-6x+8<0
(x-2)(x-4)<0
For this to be less than zero the factors must have opposite signs.
x>2 and x<4
2<x<4
So x is all real numbers between 2 and 4 or in interval notation
x=(2,4)
Answer:
WRS and VRT are vertical angles
Step-by-step explanation:
Vertical angles are formed by the same lines and share a vertex
WRS and VRT are vertical angles
701 = 21 + 68w
701-21= 680
680/68=10
w=10
Answer:
the interest is $975
the total amount is $5975
Step-by-step explanation:
lets use tje formula
I=PRT
where I is interest earned
P is the principal amount(original amount)
R is the rate of interest
and T is the time in years
so
the principal amount is 5000 since it is the original amount
rate is
=0.065
time is 3 years
lets plug these values into our equation:
5000*0.065*3=I
5000*0.065*3=975
the interest is $975
the next part of the question is asking for the balance or the total amount which is principal+interest
5000+975=5975
the total amount or balance is $5975
hope this helps
