8 0

Answer:

75

Step-by-step explanation:

Homework mean x 10%: (80+100+90)/3 x 0.1 = 90 x 0.1 = 9

Quiz mean x 25%: (84+90+72)/3 x 0.25 = 20.5

Test mean x 45%: (64+72)/2 x 0.45 = 30.6

Sum of means/percentage of grade: 9 + 20.5 + 30.6 = 60.1/.8 = 75.125

Find the area of each square and add them to find the area of the rectangle

The area of a square = side * side

The areas are:

1*1= 1

4*4 = 16

7*7 = 49

8*8 = 64

9*9 = 81

10*10 = 100

14*14 = 196

15*15 = 225

18*18 = 324

The sum of the areas =

324+225+196+100+81+64+49+16+1

= 1056 units ^2

Given the following functions f(x) and g(x), solve (f ⋅ g)(3) and select the correct answer below:
Ksenya-84 [330]
I believe you may have the order incorrect. If we were looking at g(f(x)) the answer would be 47. We would get this by sticking the 3 in for x in f(x) and solving, which would give us 48. We would then stick that answer in for x in the g(x), giving us 47. 

In its current order the answer would be 28.
