Fred borrowed $4,000 from a bank to buy a motorcycle. He will pay back the loan in 3 years with simple interest, at an interest rate of 15% per year. What is the total amount the he will pay after 3 years?

$1800

Step-by-step explanation:

4000 × 3 = 12000

12000 × 0.15 = 1800

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
