Step-by-step explanation:
The domain is the values for the inputs
Since all values are allowed for the input
The domain is all real numbers
5.05654165E45 is your answer
Answer:
Step-by-step explanation:
To solve this problem you need the function
h(t) = -16t2 + v0t + h0
where t = time
v0 is the initial velocity, which in our case is 0
h0 = initial height, which in our case is 256
h(t) = 0 since we want to know when the ball will hit the ground.
0 = -16 t2 + 256
And we can solve for t
If we rearrange the terms we see that this is a difference of 2 squares
0 = 256 - 16t2
0 = (16-4t)(16+4t)
Setting each factor = 0
16-4t=0 16+4t=4
t = 4 t = -4
The second solution is discarded as time cannot be negative.
So the ball will hit the ground in 4 seconds.
Answer:
275
Step-by-step explanation:
180-130=50
25*9=225
225+50 = 275
Answer:
The price per one pound of almonds equal $2.20/0.65 lb
0.65 pounds of almonds cost $2.20
Step-by-step explanation:
Verify each case
case 1) The price per one pound of almonds equal $2.20/0.65 lb
<em>The statement is true</em>
To find the price per one pound calculate the unit rate
so
$2.20/0.65 lb=$3.38 per one pound
case 2) 2.2 pounds of almonds cost $0.65
The statement is not True
The correct is 0.65 pounds of almonds cost $2.2
case 3) Each bag of almonds weighs 2.2 pounds
Cannot be determined
In the problem there is no information about how much each bag of almonds weighs
case 4) 0.65 pounds of almonds cost $2.20
The statement is True
The point (0.65,2.20) lie to the line of the the graph
