Answer: G(x) = cos(x) - 1
Step-by-step explanation:
We know that y = cos(x)
remember that cos(0) = 1.
Now, by looking at the image we can see that G(x) seems to be a vertical shift.
Remember that for a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
If N is positive, the shift is up
if N is negative, the shift is down.
In this case we can see that when x = 0, G(0) = 0.
And remember that cos(0) = 1, then G(x) is one unit below the graph of y = cos(x).
Then we can see that G(x) is a vertical shift of one unit downwards.
Then:
G(x) = cos(x) - 1

Answer:
For
Car A : 30
Car B : 20
Step-by-step explanation:
Let the speed at which Car A travels be x and the time of travel be T. Recall that
speed = distance/time
Hence for Car A.
x = 90/T
T = 90/x
since Car B is B going 10 km/hr slower travels 60 km then
T = 60/(x - 10)
equating both equations
90/x = 60/(x - 10)
cross multiply
90(x - 10) = 60x
90x - 900 = 60x
90x - 60x = 900
30x = 900
Divide both sides by 30
x = 900/30
= 30
This is the speed of Car A : 30km/hr
The speed of Car B = 30 - 10 = 20 km/hr
