Answer:
the graph of the parabola opens upwards.
Step-by-step explanation:
For any quadratic equation of the form
is true that:
if the main coefficient "a" is negative then the graph of the parabola opens downwards.
If the main coefficient "a" is positive, the parabola opens upwards
In this case the parabola is 
Note that 
and 
therefore the graph of the parabola opens upwards.
Answer:
Step-by-step explanation:
1 yard = 3 feet = 36 in
so 1 in = 1/36 yard, 1 ft = 1/3 yard.
The volume of the layer of the topsoil, is:
4 in * 28 ft * 14 ft = 4 *(1/36)*23*(1/3)*17*(1/3) yard cubed =
(4*28*14)/(36*3*3)= 1955/324=
The store only sells increments of 1/4 = 0.25 cubic yards.
we need 6.034/0.25=
So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
80.50 kilometers. 1.61*50=80.50
P(2oranges and 1lemon)=2/3 (orange) · 1/2 (lemon)
P(2O and 1L) = 2/6 = 1/3
1/3 chance of getting 2 orange and 1 lemon out of the bag.
