Answer:
A) y = 4/3 x - 1/3
Step-by-step explanation:
(4,5) and (-2,-3)
Slope = (5 + 3)/(4 + 2)
= 8/6
= 4/3
Equation
y + 3 = 4/3(x + 2)
y + 3 = 4/3 x + 8/3
y = 4/3 x + 8/3 - 9/3
y = 4/3 x - 1/3
Answer:
y = 4/3 x - 1/3
X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)
Answer:
A: 6 triangles with height 10.4 inches each and base 12 inche
B: 62.4 square inches
C: 374.4 square inches
Step-by-step explanation:
Part A: You can form a triangle by connecting E to the top of the segment and connecting the top of the segment to D. Recreating this with each section will create 6 triangles with height 10.4 inches each and base 12 inches.
Part B: The area of a triangle is A = 1/2b*h. Substitute h = 10.4 and b = 12.
A = 1/2*10.4*12 = 62.4
Part C: There are 6 triangles each with area 62.4. So the area of the whole figure will be 6*62.4 = 374.4.
