Answer is <span>a. d = 26.2 km, C = 82.31 km
D = 2r = 2 x 13.1 = 26.2
C = 2pi r = 2 x </span>3.14159265359 x 13.1
C = 82.31
The answer would be -81t^2+16
The correct answer is the third choice, Quadrilateral.
Answer:
-1/3
Step-by-step explanation:
Use the formula, (y2 - y1)/(x2 - x1). In this case, there is a negative slope.
Start from point, (1, 9) and go to point (4, 8).
Use the formula:
(y2 - y1)/(x2 - x1)
Y2 = 8
Y1 = 4
X2 = 9
X1 = 1
(8 - 9)/(4 - 1) = -1/3
Therefore, the slope is -1/3
