Find the value of c so that the polynomial p is divisible by (x+2)

alexandr1967 [171]

Answer:

The value of c is 8.

Step-by-step explanation:

When a function is divisible by a factor, it will get 0 value. So, you have to substitute x = -2 into p(x) and equals to 0 :

$p(x) = 4 {x}^{3} + c {x}^{2} + x + 2$

$p( - 2) = 4 {( - 2)}^{3} + c {( - 2)}^{2} + ( - 2) + 2$

$4( - 8) + 4c - 2 + 2 = 0$

$- 32 + 4c = 0$

$4c = 32$

$c = 32 \div 4$

$c = 8$

What is the total amount for an investment of $1600 invested at 4.25% for 20 years and compounded continuously?

galina1969 [7]

Answer:

$3743.43

Step-by-step explanation:

The amount is given by the formula ...

A = Pe^(rt)

where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...

A = $1600·e^(0.0425·20) = $1600·e^0.85

≈ $1600·2.33964685 ≈ $3743.43

The amount in the account will be $3743.43.
