Step-by-step explanation:
5*9 is 45. The angles of a triangle always add up to 180 degrees. 45+75+60=180. Hope this helps!
7
75 + 60 = 135
180 - 135 = 45
45/5 = 7
Ben is 97.5 inches tall.
Alex is 32.5 inches tall.
We have been given a function . We are asked to find the formula which gives the x-coordinates of the maximum values for given function.
We know that cosine function oscillates between and 1 that is minimum value of cosine is and maximum value is .
We also know that and after period of cosine is . This means after every , we will get to .
So maximum of cosine is , where n is an integer.
Therefore, our required formula is , where,
Total pictures = 84+12 = 96
roll of films = 96 / 24 = 4
