First you must know that for remarkable angles: cos (0) = 1, cos (π) = - 1, cos (π / 2) = 0, cos (3π / 2) = 0, cos (2π) = 1. Then, by simple substitution in the given formula, you can find the solutions of x. Which for the interval [0, 2π) are: x = π, x = pi divided by two and x = three pi divided by two.Attached solution.
Answer:
the amount after 3 weeks is $37.33
Step-by-step explanation:
Given that
His balance is -$48.82 i.e. overdraft
Now in order to get the positive balance, he plans to deposit the money of $28.55 per week
We need to find out the amount after 3 weeks
So,
= -$48.32 + $28.55 + $28.55 + $28.55
= $37.33
hence, the amount after 3 weeks is $37.33

Answer:
3
Step-by-step explanation:
r = 255
r = R-2RF/W
R = 1,750
F = 63.2
W = 148
Now, we need to plug the values in to substitute the variables with real numbers.
r = 1750-2(1750 x 63.2)/148
First, solve for the parentheses.
r = 1750-2(110600)/148
Second, multiply by 2.
r = 1750-221200/148
Next, divide by 148.
r = 1750 - 1494.594
Then, we subtract.
r = 255.406
Lastly, we round it to the nearest whole number.
r = 255
