Some countries implement income taxes on a progressive scale. Meaning, part of your income can be taxed at one rate and part of your income can be taxed at a different rate. Write a piecewise function that represents the following tax scale. Income: Tax Rate: 0 - $50,000 27% $50.001 - $100.000 $13,500 plus 35% for the income over $50,000 $100.001 and over $31.000 plus 45% for the income over $100,000 Write a piecewise function that represents the situation above.​

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
