Step-by-step explanation:
Using synthetic division of polynomials 3x⁴-2x²+4x+9÷x+2. Rewrite the dividend as 3x⁴+0x³-2x²+4x+9
2 | 3 0 -2 4 9
| 6 -12 20 -32
3 -6 10 -16 41
So the quotient is 3x³-6x²+10x-16 with a remainder of 41
Therefore, 3x³-6x²+10x-16+(41/x+2)
To answer this since the discount is 15% the retail is 75% so you would put it in a ratio or part over whole so .75=2210 and 100%=x so then you would divide 2210 by .75 and you get 2946 but I’m not sure so...
Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
Answer:
c=2
Step-by-step explanation:
3c+8=14
subtract 8 from both sides
3c=6
divide both sides by 3
c=2
