Celina earns $5.4 per hour.
ok so lets start of with the fact that the whole thing is 21 units.
So we do 21-9=12 so then we now know that the rectangle is 12 so then we do 12*8 units which is= 96 . Now the triangles. so the first one we know that its 8*3 and times it by 1/2 because two triangles is equal to a rectangle so the first triangle is 12 and now the second. its 9-3= 6 then its 6*8*1/2 which is equal to 24 so now the final answer is
96+12+24 which is equal to 132 so i'm guessing it 132 square units
Answer: 3
Explanation: logarithm base 8 of 512 is 3
Answer:
24 units^2
Step-by-step explanation:
bc=6
ab=8
area of a triangle: b*l/2
6*8/2=24
(f ○g ) (2)= 11
Step-by-step explanation:
(f ○g ) (x)= (f(g(x))
= 5( x² -1) – 4
= 5x² – 5 – 4
= 5x² – 9
(f ○g ) (2)= (f(g(2)) = 5 (2)² – 9 = 5(4) – 9 = 20 – 9 = 11
I hope I helped you^_^
