Answer:
For 90 minutes of TV there will be 24 mins of commercials
Step-by-step explanation:
You start with 30 and keep adding 30 mins each time until you get to 90. (So..30..60..90) each time you add 30mins you add 8 more minutes to the commercials)
30 mins tv----8mins commercials
60 mins tv----16mins commercials
90 mins tv----24mins commercials

Answer:
The value of a = 3
Step-by-step explanation:
Given the function
From the attached graph, it is clear that
at x = 0,
∵
Thus
When x = 0, the y-intercept will be:
From the attached figure, it is clear that
at x = 0, the value of y = 3
so
putting y = 3 in the equation
3 = a ∵
Therefore, the value of a = 3
Answer:
Step-by-step explanation:
W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form .
We know that vertex form of parabola in form , where (h,k) in vertex of parabola.
Upon substituting coordinates of vertex, we will get:
To find the value of a, we will substitute coordinates of point (0, -1) as:
Therefore, our required equation would be .
