Answer:
The value of the expression at w=3 is;
Explanation:
Given the expression;
Then when w=3, the value of the expression is;
The value is gotten by replacing/substituting w with 3 in the expression;
Therefore, the value of the expression at w=3 is;

Answer:
The 6% simple interest account earns more interest in 2 years.
Step-by-step explanation:
You can compare the multipliers in the interest formulas.
For simple interest, the amount in the account (A) starting with principal P and earning at rate r for t years will be ...
A = P(1 +rt)
For the values given, r=.06 and t=2, the multiplier is ...
1 +rt = 1 +.06·2 = 1.12
__
For interest compounded annually, the amount will be ...
A = P(1 +r)^t
For the given values, the multiplier is ...
(1+r)^t = (1.04)^2 = 1.0816
__
Since 1.12 > 1.0816, the account earning simple interest will earn more interest.
Answer: All real numbers (choice A)
We can replace x with any real number we want without worrying about restrictions. There won't be any issues such as dividing by zero or applying the square root to a negative number.
1 root.
The reasoning is the same for your other question except x is positive this time round giving x=8 as your only root.
