What must be added to f(x) = 4x4 + 2x3 -2x2 +x - 1, so that the resulting polynomial is divisible by g(x) = x2 +2x -3?

s344n2d4d5 [400]

Answer:

p(x) = -4*x^4 - 2*x^3 + 3*x^2 + 1*x - 2

Step-by-step explanation:

We want to find a polynomial p(x), such that if we add that polynomial to:

f(x) = 4*x^4 + 2*x^3 - 2*x^2 + x - 1

we get:

g(x) = x^2 + 2*x - 3

This is:

f(x) + p(x) = g(x)

Notice that f(x) is a polynomial of degree 4 and g(x) is a polinomial of degree 2, so p(x) must be also a polynomial of degree 4.

p(x) = a*x^4 + b*x^3 + c*x^2 + d*x + e

Then we get:

(4*x^4 + 2*x^3 - 2*x^2 + x - 1) + (a*x^4 + b*x^3 + c*x^2 + d*x + e) = x^2 + 2*x - 3

We can simplify the left side to:

(4 + a)*x^4 + (2 + b)*x^3 + (-2 + c)*x^2 + (1 + d)*x + (-1 + e) = x^2 + 2*x - 3

Because in the right side we do not have terms with exponent 4 and 3, we must have that:

4 + a = 0

2 + b = 0

and for the other exponents of x we just match the exponent in the left side with the correspondent one in the right side:

(-2 + c) = 1

(1 + d) = 2

(-1 + e) = -3

Solving the 5 equations we get:

a = -4

b = -2

c = 1 + 2 = 3

d = 2 - 1 = 1

e = -3 + 1 = -2

Then the equation for p(x) is:

p(x) = -4*x^4 - 2*x^3 + 3*x^2 + 1*x - 2

A biologist is developing two new strains of bacteria. Each sample of Type 1 bacteria produces four new viable bacteria, and eac

gayaneshka [121]

The cost can be optimized by using a Linear Programming given the linear constraint system

To minimize the cost, the biologist should use 60 samples of Type I bacteria and 0 samples of Type II bacteria

Reason:

Let X represent Type 1 bacteria, and let Y, represent Type II bacteria, we have;

The constraints are;

4·X + 3·Y ≥ 240

20 ≤ X ≤ 60

Y ≤ 70

P = 5·X + 7·Y

Solving the inequality gives;

4·X + 3·Y ≥ 240

$Y \geq 80 - \dfrac{4}{3} \cdot X$ (Equation for the inequality graphs)

The boundary of the feasible region are;

(20, 70)

(20, 53. $\overline 3$ )

(60, 0)

(60, 70)

The cost are ;

$\begin{array}{|c|c|c|}X&Y&P= 5\times X + 7 \times Y\\20&70&590\\20&53.\overline 3&473.\overline 3\\60&0&300\\60&70&790\end{array}\right]$

Therefore, the minimum cost of $300 is obtained by using 60 samples of Type I and 0 samples of Type II

In a study of variation in systolic blood pressure upon application of leaches, it is found that the standard deviation of the 2

kondor19780726 [428]

Answer:

Test statistic is [(n - 1) *S^2 ]/ σ ^2 = [(22 - 1) *(3.9)^2 ]/ (3.4) ^2

with 21 degrees of freedom

Yes this data fits at the 10% level of significance, so I would not reject that statistic of 3.9 mmHg as a wrong standard deviation

Step-by-step explanation:

use the expression I attached in the image to find

[(n - 1) *S^2 ]/ σ ^2

where S = the standard deviation calculated from the sample of n trials.

sigma is the population standard deviation.

[(22 - 1) *(3.9)^2 ]/ (3.4) ^2 = 21 * 15.21 / 11.56 = 27.6306

all we have to do now is to make sure this number is in the 90 % confidence

interval. remember this has 21 degrees of freedom, look at the chi-squared chart.

11.5913 < 27.6306 < 32.67905

where 11.5913 is the lower bound of the chart

and 32.67905 is the upper bound
