You don't have the graph icon here, so we'll have to graph this parabola without it.
Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).
Plot (0,3). Besides being the vertex, this point is also the max. of the function.
Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.
Answer:
9.3
Step-by-step explanation:
Is means equals and of means multiply
W = 30% * 31
Change to decimal form
W = .30 *31
W = 9.3
Answer:
53 minutes
Step-by-step explanation:
Let x be the time required for a full video upload. This would have the unit of (minutes/full upload). Since the upload rate is constant, we can write:
(0.17)*(x) = 9 minutes
This equation states that 17% of the full upload time is 9 minutes.
Solve for x:
x = (9 minutes)/(0.17)
x = 52.9 minutes or 53 minutes with 2 sig figs
The reflection of (-7, 2) across the y-axis is (-7, -2) (hope this helps ;3)
