Answer:
The profit is 1.75x-0.5
Step-by-step explanation:
Mathematically,
profit = sales - cost
So with respect to this case, we have that;
Profit = s(x) - c(x)
Profit = 2x - (0.25x + 0.5)
Profit = 2x - 0.25x -0.5
Profit = 1.75x - 0.5
Therefore, 2.52 ÷ 50.8 ≈ 0.0496.
0.049600...
=0496
Answer:
TR = 3 units
Step-by-step explanation:
Recall: tangents drawn from an external point are equal to each other
Therefore,
TR = UR
We need to find UR first
Thus:
UR = PR - UP
PR = 12 (given)
UP = SP = 9 (tangents drawn from an external point are congruent)
UR = 12 - 9
UR = 3 units
Therefore,
TR = UR = 3
TR = 3 units
Okay so, the formula we can use for this problem will be x= 410/.82, x being the original price of the TV. The .82 was figured to make up for the 18% lost from the original price. 410/.82=500. so the original price of the TV would be $500. To check our answer we can multiply 500 by the sale price and subtract that amount from the original $500. Like so: 500-(500*.18)=410.
Step-by-step explanation:
1) Your problem → (4x^2 - 17x^3 + 9) - (x^2 + 9x + 23x^2 + 11)
(-17x^3+4x^2+9)-(x^2+23x^2+9x+11)
=-17x^3+4x^2+9-x^2-23x^2-9x-11
=-17x^3+4x^2-x^2-23x^2-9x+9-11
=-17x^3-20x^2-9x-2
2) Your problem → 0 - 19.73 - 25x^2 - 12x - 3
=0-19.73-25x2-12x-3
=-25x^2-12x-22.73
3) - 10.x^3 – 162x^2 – 24x - 4
4) Your problem → 17x^3 - 20x^2 - 9x^2
=17x^3-20x^2-9x^2
=17x^3-29x^2
5) -16x^3 – 243x^2 – 12x – 3
