Sophia is saving money to buy a chemistry set. The first week she saves $1, the second week $4, the third week $16, and so on. How much money will she save the fifth week?

Step-by-step explanation:

If the money saved is the y coordinate, it appears that each y coordinate is multiplied by 4 to get to the next one.  1 * 4 = 4, 4 * 4 = 16.  16 * 4 = 64 in the 4th week, and 64 * 4 = 256 in the 5th week.

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.
