Answer:
below..
Step-by-step explanation:
- slope = (y - y1)/(x-x1) = (6 - 3 )/(1-0) = 3 is the slope/ gradient
- equation of the line = y -3 = 3(x - 0) => y = 3x + 3
Step-by-step explanation:
C = 2πr = 53.38cm
r = C / 2π = 53.38cm / 2π = 53.38/ 6.283185307179586 = 8.4956cm
A = πr^2 = π × (8.4956cm^)2 = 226.4cm^2
A basketball court is in a rectangular shape and the perimeter for a rectangle is the addition of each one of its sides or P= 2W + 2L (L= length & W= width). P=90 L = 2w+6 With the information provided your have to formulate the equation: 90=2W+2(2W+6) Then solve for W: First distribute the 2 90=2W + 4W + 12 Combine common factors 90 = 6W + 12 Subtract 12 from both sides 78 = 6W Divide 6 on both sides W=13 Now that you have your width, you can plug it into the equation to find the length (L=2W+6) 2(13) +6 =L 26 + 6 = L 32 = L You can always double check by making sure that the totals equal 90 for the perimeter 32+32+13+13=90 2(32) + 2(13) =90
