sorry its so messed up just right it from the top down:)
Answer:
$66.75 is what you'll make from over time.(this does not include the pay from the 35 hours this is only the over time)
Step-by-step explanation:
If you were to work (WITH OUT OVERTIME) you would have $311.50
If you were to work (WITH OVERTIME INCLUDED) you would get $378.25
Answer:
(-1x^3 - 3x - 8)(2x^2)
Step-by-step explanation:
Note how x^2 is a factor of all three terms of this polynomial. Also, 2 is a factor of those three terms. Thus, the GCF is 2x^2.
Dividing -2x^5-6x^3-16x^2 by 2x^2, we get:
(-1x^3 - 3x - 8)(2x^2) (the polynomial in factored form)
Answer:
The last equation x2 - 2x -4 = 0
has solution (x - 1)^2 - 5 = 0, x = 1 + root(5) or x = 1 - root(5)
Step-by-step explanation:
If a quadratic function has roots 1 and 5
f(x) = (x -1)(x- 5)
f(x) = x^2 - 6x + 5
Unless you meant. -4 and 6 ?
g(x) = (x + 4)(x - 6)
g(x) = x^2 -2x -24
-------------------------
Or did you mean x = 1 and x =4 ?...
x^2 + 2x + 4 = 0 : complete square x^2 + 2x + 1 + 3 = 0, (x+1)^2 + 3 = 0
x^2 - 2x + 4 = 0 : complete square: (x -1)^2 + 3 = 0
0x^2 + 2x - 4 = 0, 2x - 4 = 0, x = 2
x^2 - 2x - 4 = 0 becomes: x^2 - 2x + 1 - 1 -4 = 0 ; (x - 1)^2 - 5 = 0
The reaction times form a straight line with gradient of 60/140 = 3/7 m/kph
Reaction time at 130 kph = 3/7 x 130 = 390/7 = 56 m to nearest whole number
