Pay=pay per hour times hours
A. M=12x
B. for more than 30, so
T=amoutn earned already (30hr normal)+overtime
T=12(30)+16y
T=360+16y
C.
hmm, 360 is if worked 30 hours, the rest is overtime
so
408=360+16y where y is overtime
minus 360 both sides
48=16y
divide both sides y 16
3=y
3 hours of overtime
In my opinion, technology is increasing bullying. It gives people the opportunity to anonymously chat people, saying anything they feel like saying in anyway they want to.
Hey there!!
How do we find inverses?
In versing is the just the flip-flop of the x and y.
Given equation :
...f(x) = √(2x-6)
... y = √(2x-6)
... x = √(2y-6)
Square on both sides
... x² = 2y-6
... x² + 6 = 2y
... x² + 6 / 2 = y
Inverse :
f(x) = ( x² + 6 ) / 2
( ii ) f(x) = ( x - 2 )³ + 8
... y = ( x - 2 )³ + 8
... x = ( y - 2 )³ + 8
... x - 8 = ( y - 2 )³
... cube root on both sides
... ∛( x - 8 ) = y - 2
... ∛(x - 8 ) + 2 = y
Inverse :
f(x) = ∛( x - 8 ) + 2
Hope my answer helps!!
Answer:
Step-by-step explanation:
Rate = 10%
Time = 2 years
Initial CO2 = 280000 metric ton
1st year
10% × 280000
= 28000 metric ton.
2nd year
10% × (280000 - 28000)
= 25200 metric ton.
Metric ton of CO2 produced at the end of the 2nd year = 252000 - 25200
= 226800 metric ton of CO2.
