Answer:
B) It rises to the left and falls to the right
Step-by-step explanation:
Degree: odd (5) and leading coefficient (negative) (-2)
Answer:
Axis of Symmetry is x = 2
Vertex is (2, -9)
X Intercepts are (5, 0) and (-1, 0)
Step-by-step explanation:
Quadratic Equation is in standard form. Formula find the x value of the vertex in standard form is -b/2a
a=1
b=-4
c=-5
--4/2(1) = 2
Plugin to find the y value of the vertex.
2^2-4(2)-5=y
4-8-5=y
y = -9
The x value of the vertex (in this case is 2) is the axis of symmetry. Therefore the axis of symmetry is x=2
Factor the equation to put into intercept form.
(x-5)(x+1) = y
The equation can be FOIL-ed to get back to standard form.
Separate the 2 parentheses and whatever can cancel the parentheses are your intercepts.
For (x-5) your intercept is (5, 0)
For (x+1) your intercept is (-1, 0)
The x intercepts are where the parabola will cross the x axis on the graph.
15 + 10 + 16 = 41
for the unshaded area
subtract the area of the whole rectangle shaded.
whole rectangle is
16(8) = area of 128
unshaded = 128 - 41 = 87
so your answers are
41, and 87
Answer: 
Step-by-step explanation:
From the given picture, it can be seen that the radius of the circle = 16 units
Also, the measure of central angle XYZ 
radians
The area of sector with radius r and angle x radian is given by :-
Now, the area of the shaded sector is given by :-
