Answer:
The measure of the two supplementary angles are 65 degrees and 115 degrees.
Step-by-step explanation:
The sum of supplementary angles is equal to 180 degrees. Let x and y are two angles such that,
According to given condition,
One supplementary angle is 15 degrees less than twice the other, it means,
Putting the value of x from above equation in equation (1),
Now put the value of y in equation (1), so,
So, the measure of the two supplementary angles are 65 degrees and 115 degrees.
The graph which represents the polynomial function g(x) is:
the 2nd graph in the second line
Step-by-step explanation:
g(x) = x³ + x² - 17x + 15 is a cubic function because the greatest power
of x is 3
All graphs represent cubic functions
So to find which graph which represents g(x) we will do these steps
1. Put x = 0 to find the y-intercept
2. If there are more than one graph have the same y-intercept we will
find the maximum and the minimum points of the cure
3. If you still don't know which graph find the x-intercepts
Now let us find the graph which represents g(x)
∵ g(x) = x³ + x² - 17x + 15
∵ x = 0
∴ g(0) = (0)³ + (0)² - 17(0) + 15
∴ g(0) = 15
∵ g(0) is the y-intercept
∴ The graph intersect the y-axis at point (0 , 15)
There is only one graph intersects y-axis at point (0 , 15)
The attached figure is the graph of g(x)
The graph which represents the polynomial function g(x) is:
the 2nd graph in the second line
