Step-by-step explanation:
Elvin and Carol together have Rs. 84. If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin. How much money, do Elvin and Carol have originally?
Let the amount of Elvin has originally = E
Let the amount of money Carol has originally be = C
E + C= Rs. 84
E + C = 84 ......Equation 1
If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin.
C + 32 = 2E
C = 2E - 32
We substitute into Equation 1
E + C = 84 ......Equation 1
E + 2E - 32 = 84
3E = 84 + 32
3E = 116
E = 116/3
E =
Answer:
Step-by-step explanation:
We want to find the polynomial function whose zero are -1 and 4i.
Recall that non-real zeros come in pairs.
There if 4i is a zero, then the conjugate -4i is also a zero.
Therefore the factors of this polynomial are:
x+1, x+4i, and x-4i are factors of the given polynomial.
Let f(x) be the required polynomial, then we can write the polynomial in factored form as:
We expand the conjugate pair using difference of two squares to get:
Expand further using the distributive property to get:
