Answer:
16 days
Step-by-step explanation:
divide 4800 by 300
(a) equation in function notation:
h(t) = 29.4t - 4.9t²
(b) The degree of the function is 2 and this is quadratic
(c) what time will the ball in its highest position?
h = 29.4t - 4.9t²
differentiate both sides and equate to zero
d(h) = 29.4 - 9.8t = 0 ; t = 3
(d) what time will it hit the ground,
h = 29.4t - 4.9t² = 0; t = 6 and t = 0
Thus, the answer is t = 6.
First we define the variables:
x = weight of a large box
y = weight of a small box
We write the system of equations:
x + y = 95
50x + 65y = 5275
The solution to the system of equations by the graphic method is:
x = 60
y = 35
Note: see attached image.
Answer:
each type of box weigh:
weight of a large box = 60 pounds
weight of a small box = 35 pounds
Check the picture below.
so the focus point is at 5, -1 and the directrix is above it, meaning is a vertical parabola, and is opening downwards, like in the picture.
keep in mind that the vertex is half-way between those two fellows, at a "p" distance from either, in this case 1 unit, since the parabola is opening downwards, "p" is negative then, or -1, and the vertex will be from 5, -1 up one unit, so 5,0.
