If you put $20 in your savings account each week, how much have you saved after n weeks?

Step-by-step explanation:

Let n represent number of weeks.

We are asked to find the amount saved in account, if we put $20 in savings account each week.

Since we put same amount of money in account per week that is $20, so amount of money after n weeks would be n times 20.

Therefore, there would be dollars in account after n weeks.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
