Answer: Graph D will be correct graph for the given function.
Explanation:
Given function
Since it is a bi-quadratic equation thus it must have 4 roots and (0,1) is one of its point.
Moreover, the degree of the function is even thus the end behavior of the function is, as and as
In graph A, function has four root but it does not have the end behavior same as function f(x).( because in this graph , as and , as .) so, it can not be the graph of given function.
In graph B, neither it has four root nor it has the end behavior same as function f(x).(because in this graph as and as .) so, it can not be the graph of given function.
In graph C, neither it has four root nor it has the same end behavior as function f(x).(because in this graph as and as.) so, it also can not be the graph of given function.
In graph D it has four root as well as it has the same end behavior as the given function. Also it passes through the point (0,1).
Thus, graph D is the graph of given function.
Answer:
(x-5)<em>squared </em>+ (y-4)<em>squared </em>= 49
Step-by-step explanation:
Formula:
(x-h)<em>squared </em>+(y-k)<em>squared </em>= r<em>squared</em>
Since the number 5 is in the tenths place, there are 5 tenths.
Answer:
230 mph
Step-by-step explanation:
Let speed of plane in still air be x. Therefore, when against the wind speed, the resultant speed is x-40 mph. Equally, when with the wind speed, the resultant speed is x+40 mph. The time is the same hence we can express these as
By cross multiplication
675(x-40)=475(x+40)
675x-27000=475x+19000
200x=46000
X=46000/200=230 mph
Answer:
-16
Step-by-step explanation:
Replace all t with -5:
w(t) = 3t - 1
w (-5) = 3(-5) - 1
w(-5) = -16
