Answer:
$8.60
Step-by-step explanation:
Let’s find the cost for each item
Apples: 2.5 x 1.30 = 3.25
Grapes: 2.5 x 1.65 = 4.125
Bananas: 2.5 x 0.49 = 1.225
Now we will add all the costs which will give use our total!
3.25 + 4.125 + 1.225 = 8.6
So the answer will be $8.60

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.
D/dx ( cos (4x)) = - sin (4x) · d/dx ( 4x) = - 4 sin (4x)
It would be: 0.25 = 25/100 = 1/4
so, your answer is 1/4
The correct answer should be A, at positive 3 , and D , at positive 3
