<span>1. </span><span>Fiona drives 60 miles per hour on the Highway
And drives 30 miles per hour on the City.
She got a total of 312 hours in the highway and 112 hours in the city
Find the average speed of Fiona:
Formula of Speed
=> S = d / t
Let H be the distance in Highways
and Let C be the distance in City
=> H = 60 x 312
=> H = 18 720
=> C = 30 x 112
=> C = 3360
=> Total distance = 18 720 + 3 360
=> 22 080 miles
Let’s find the total time
=> H + C
=> 312 + 112
=> 424 hours

Speed = 22 080 / 424
S = 52.1 miles per hour

Step-by-step explanation:

Using the topic of transformation of functions(rules shown in picture above)

the the (x-2) moves the graph to places to the right

and as the sine graph goes through 0 and so you add 2 to the right (but there is a problem in the graph should in the picture as it should me labeled 0,90,180,270,360 not these small numbers)

hope it helps!! :)
