-4 their ur answer ur welcome
It looks like it’s b. Triangle 2
Answer:
C) see explanation
Step-by-step explanation:
Given function:
<h3><u>Part A</u></h3>
To find the <u>x-intercepts</u>, set the function to zero, factor and solve for x:
Therefore:
Therefore, the x-intercepts of the graph of f(x) are
<h3><u>Part B</u></h3>
As the leading coefficient is negative, the parabola will open downwards. Therefore, the vertex of the graph of f(x) will be a <u>maximum</u>.
The x-coordinate of the vertex is the midpoint of the x-intercepts:
To find the y-coordinate of the vertex, substitute the x-value into the function:
Therefore, the <u>coordinates of the vertex</u> are:
<h3><u>Part C</u></h3>
Find the y-intercept by substituting x = 0 into the function:
Therefore, the y-intercept is (0, 16)
To graph f(x)
- Plot the vertex
- Plot the x-intercepts
- Plot the y-intercept
- Draw a parabola opening downwards with the vertex as the maximum point.
The axis of symmetry is the x-value of the vertex. Use this to help ensure the curve is symmetrical.
There are six p's, which add up to give a sum of thirty six
6p=36
Divide six by both sides to get the value of p
36/6 is 6
p is equal to six
Step-by-step explanation:
Given,
Current quantity of emission, P = 40 millions,
Reduction in emission per year, r = 35% = 0.35,
Thus, the quantity of emission after t years,
Which is the required function.
