In 1989, Dutch ice skater Dries van Wijhe skated 200 km at an average speed of 35.27 km/h. How long was he skating? Use the formula d = rt, where d is the distance in km, r is the rate in km/h, and t is the time in hours. How long would it take to earn $6,000 in interest on a principal of $9,000 at an annual simple interest rate of 4.1%? Use the simple interest formula I = prt, where I is the interest earned, p is the principal, r is the interest rate per year, and t is the time in years.

step-by-step explanation:

2 x 40 = 80

80/5

= 16

60 + 3

63

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
