Answer:
See explanations below
Explanation:
Vertex of a graph is the lowest point on the curve. The vertex occurs at (1.75, -2.5)
The axis of symmetry is the point on the x axis of the line that cuts through the minimum point. The axis of symmetry occurs at x = 1.75
x intercept is the point where the curve cuts the x axis. The x intercept occurs at x = 0 and x = 2.5
To get the minimum, we will use the formula;
c - b^2/4a
The equation of the curve is expressed as;
(x-0)(x-2.5)
= x (x-2.5)
= x^2 - 2.5x
a = 1, b = -2.5, c = 0
minimum = 0 - (-2.5)^2/4(1)
minimum = -6.25/4
minimum = -1.5625
Minimum value occurs at the base of the parabola. The minimum value of the function is -2.5
y intercept is the point where the curve cuts the y axis. The y-intercept occurs at y = 0.
Answer:
2y + 18
Step-by-step explanation:
8 + 2(y + 5)
8 + 2y + 10
2y + 18
all you have to do is see whether both variables of each point meet both contraints:
for a) 1<3 and 2>1 is true so a is a solution to the system
Well, since we have not actually done this experiment, we cannot use a experimental probabiltity, so we can say the correct answer is: <span>
</span><span>D. The theoretical probability is 50%.</span>
