Answer:
I imagine you aren't using calculus, so:
A: the leading term is 
, so it opens upwards.
B. First coordinate of the vertex is 
, the second coordinate we'll find by replacing the value: 
C. Quadratic formula or if you stare at the equation long enough you can rewrite the equation as 
. At this point the x intercepts are the zeroes of the function, or -6 and 2.
D. The y-intercept is the value of the function at 0, or the constant term: -12
E. The graph has a minimum since the curve opens upwards.
Answer:
The slope is 2.5
Step-by-step explanation:
y = 2.5x + 5 or
y =
5/2x + 5
When x=0, y = 5
When y=0, x = -2
The area of the sector is 5.9 m²
Step-by-step explanation:
The problem pertains to the area of an arc.
We know that area of the arc is given by= (central angle/360°)*π*r
²
Where r is the radius of the circle= diameter/2
Here diameter of the circle= 6 m
⇒Radius= 6/2= 3m
Substituting the values of the central angle as 75° (given), “r” as 3m, we get-
⇒Area of the sector= (75°/360°)*3.14*(3)
²
⇒Area of the sector=0.20834*3.14*9
⇒Area of the sector=5.9 m² (rounded off to the nearest tenth place after decimal)
Hence, area of the sector is 5.9 m²
