The piecewise function for this should be
.
We can find the first equation simply. He gets 20 every hour up to 42 hours. Therefore, the function gives us our first equation of y = 20x when x < 42.
The second one, we must know what the base amount he would make before starting to make 28 an hour. The 28 an hour would be 28x, but he would have already made 840 before hand. Which we can determine by multiplying the base of 42 hrs by 20.
42 * 20 = 840.
3/4-(x+1/8)=5/16
3/4-x-1/8=5/16
3/4-1/8-5/16=x
Common denominator: 16
x=(4×3-2×1-5)/16=(12-2-5)/16=5/16
Answer: x=5/16
96*72=6912
One ton is $72
You have 96 tons
So you take $72 96 times
The slope is -3x i think
just a tip there’s this website (i think there’s an app too?). allied khan academy it’s basically for school and there’s lots of videos of what you’re doing
Answer:

Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let h represent the hypotenuse, then
h² = 5² + (
)² = 25 + 2 = 27 ( take the square root of both sides )
h =
← exact value
