Answer:
A. x = -2, 5/2
B. Minimum
Vertex: (1/4, -81/8)
C. Draw a concave up graph connecting the x-intercepts, vertex and the y-intercept
Step-by-step explanation:
f(x) = 2x² - x - 10
2x² - x - 10 = 0
2x² - 5x + 4x - 10 = 0
x(2x - 5) + 2(2x - 5) = 0
(x + 2)(2x - 5) = 0
x = -2, 5/2
Vertex: (h,k)
h = midpoint of the x-intercepts (due to symmetry)
h = (-2 + 5/2) = 1/4
k = f(1/4)
k = 2(1/4)² - 1/4 - 10 = -81/8
Vertex: (1/4, -81/8)
y-intercept: when x = 0
2(0)² - 0 - 10 = -10
Draw a concave up quadratic connecting thr following points:
(-2,0)
(0,-10)
(1/4,-81/4)
(5/2,0)
The answer is angle VUR and QUR.
Hope this helps

Answer:
car a-50 kilos per hour
car b-55 kilos per hour
car b is faster
Step-by-step explanation:
150/3=50
220/4=55
Part (b)
We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.
-----------------
This means,
is the solution with the initial condition y(0) = 0.
