Answer:
Domain:{3,5,6,9}Range:{8,2,1}
Step-by-step explanation:
The domain is the set of all the values of x
. The range is the set of all the values of y
The first point is on the 10 minute line in between 4 and 6 kilometer line
The second point is on the 15 minute in between the 10 and 12 kilometers line
The third point is on the 20 minute line and 18 kilometer line
Hello! The answer to your question would be as followed:
Step 1:
5x - (3•5x^2)
Pull out like terms:
5x - 15x^2 = -5x • (3x - 1)
Final Result:
-5x • (3x - 1)
Answer:
Equation: 4 1/4 + 1 3/4
Evaluation: 5 3/4
Step-by-step explanation:
So, Nora jobs 4 1/4 miles on Monday, which is 1 1/2 miles fewer than on Tuesday.
If this was 1.5 fewer miles, we need to add 1 1/2 and 4 1/4 to get our answer
We change the denominator on 1 1/2 to be 4. So, we multiply both sides by 2 and get 1 2/4
4 1/4 + 1 2/4 = 5 3/4
<h3>Answer:</h3>
y = 17x - 4.5x²
height = 16m at 2 sec
total time = 3.77 sec
<h3>Step-by-step explanation:</h3>
Given the initial velocity of rocket = 56ft/sec
We use newton formula
<h3 /><h3>s = ut + 1/2at²</h3><h3>where s = distance</h3>
u = initial velocity
t= time
a = acceleration due to gravity = 9.8m/s²
since the rocket is launched upward, it is against the gravity so a = -9.81.
56 feet = 17.0688 = 17
suppose s = height = y and time = x
y = 17x - 1/2(9.81)x²
or
y = 17x - 4.5x²
b)
as x can not be negative so domain will be from 0 to 3.78
put value of x to find value of y and then plot these on graph
This graphs will be a parabola which opens downward.
c)
at 2 sec, y value is greatest = 16 meters
time for which rocket was in the air = 3.77sec
