The formula for simple interest is i=prt, where i is the interest, p is the principal, r is the interest rate, and t is time (in years). solve the formula for p. then use the formula to determine the principal for an account with a 2% interest rate that earned $300 in simple interest over the course of 8 years.

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.

the answer is d

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
