Answer:
c. supplementary angles
Step-by-step explanation:
If f(x) = 0, means " For which value of x, f(x) or y = 0".
Then f(x) = 0 for all points of the graph that intersects the x-axis, that is:
for x = -2, for x = 1 and for x = 3 (Answer -2, 1 or 3 only)
Answer:
Tire will be warranted for 
Step-by-step explanation:
We have given that tire is warranted for 63000 miles
We know that 1 mile = 5180 feet
So 
Diameter is given d = 2 feet
So radius 
Angular distance is given by 
Answer:
Think its B
Step-by-step explanation:
1) We can determine by the table of values whether a function is a quadratic one by considering this example:
x | y 1st difference 2nd difference
0 0 3 -0 = 3 7-3 = 4
1 3 10 -3 = 7 11 -7 = 4
2 10 21 -10 =11 15 -11 = 4
3 21 36-21 = 15 19-5 = 4
4 36 55-36= 19
5 55
2) Let's subtract the values of y this way:
3 -0 = 3
10 -3 = 7
21 -10 = 11
36 -21 = 15
55 -36 = 19
Now let's subtract the differences we've just found:
7 -3 = 4
11-7 = 4
15-11 = 4
19-15 = 4
So, if the "second difference" is constant (same result) then it means we have a quadratic function just by analyzing the table.
3) Hence, we can determine if this is a quadratic relation calculating the second difference of the y-values if the second difference yields the same value. The graph must be a parabola and the highest coefficient must be 2
