Pie r squared is the area of a circle, so 9^2(3.14etc) = so 255 square yards. So 255 x 15 = $3,825
Move 2a to the other side, making it negative
32=6a-2a
32=4a
divide both sides by 4
8=a
Answer:
36, 55 , 35, 16, 20, 71
Step-by-step explanation:
Total number of coffee drinkers, U = 100
Let
n(Cream) = C
n(Sugar) = S
n(cream and sugar) = n(CnS) = 20
Number that like cream = n(C) + n(CnS) 16 + 20 = 36
Nunber that like sugar = n(S) + n(CnS) = 35 + 20 = 55
Sugar but not cream = 35 (from. Venn diagram)
Cream but not sugar = 16 (From. Venn diagram)
Cream and sugar = n(CnS) = 20
Cream or sugar = n(CuS) = 16 + 20 + 35 = 71
Answer:
7) (f+g) (x) = 4^x + 5x -5
8) (f-g) (x) = 4^x + x - 5
Step-by-step explanation:
7) Find (f +g)(x)
(4^x + 3x + 2x - 5)
(4^x + 5x -5)
(f+g) (x) = 4^x + 5x -5
8) Find (f-g)(x)
(4^x + 3x - 2x - 5)
(4^x + x - 5)
(f-g) (x) = 4^x + x - 5
