i just got trolled on brainly how did this happen hffghjjkksk
Answer:
- the domain is [0,129]
- 112 mm
- 1942
Step-by-step explanation:
1. The function is good for years 1880 to 2009, 0 to 129 years after 1880. Values of x can be anything in the domain [0, 129].
__
2. 1950 -1880 = 70. The year 1950 corresponds to x=70, so the function tells us the water level rose ...
f(70) = 1.6·70 = 112 . . . . . mm
__
3. We want to find x when f(x) = 100. That will be the solution to ...
100 = 1.6x
100/1.6 = x = 62.5
Then 62.5 years after 1880 is year 1942.5. The water level was 100 mm higher than in 1880 in the year 1942.
To find her speed, divide the total distance by the total time:
12.5 miles / 5 hours = 2.5 miles per hour.
You want to multiply 40 hours by the regular hourly pay which would be $9.14,
9.14*40= 365.6
Overtime is generally 1.5 times regular pay so take 9.14*1.5= 13.71 and this would be your overtime hourly rate
Regular hourly rate (1x) : $9.14
Overtime hourly rate (1.5x): $13.71
Take your 8 hours of OT and multiply it by 13.71
13.71*8= 109.68
Add 365.6 and 109.68 to get a final answer of 475.28. The answer would've been C
This is the answer plz tell me if its wrong
