HELP!!! Use the factor Theorem to determine whether the binomial x+1 is a factor of the polynomial function f(x) =2x^3-9x^2+13x-

Dovator [93]

ANSWER

A. No because f(c)=-30

EXPLANATION

The given polynomial is

$f(x) =2x^3-9x^2+13x-6$

If x+1 is a factor , then f(-1) must evaluate to zero.

$f( - 1) =2( - 1)^3-9( - 1)^2+13( - 1)-6$

$f( - 1) =2( - 1)-9( 1)+13( - 1)-6$

$f( - 1) = - 2-9 - 13-6$

$f( - 1) = -11 - 19$

$f( - 1) = - 30$

Since f(-1) is not equal to zero, x+1 is not a factor of

$f(x) =2x^3-9x^2+13x-6$

Maru [420]

Answer:

Renata has a home loan for $150,000 at 7.5% interest for 30 years and her payment is $987.00 per month.

I have solved this using excel sheet that is attached here.

p = $150000

r = 7.5%

t = $30\times12=360$

EMI = $987

You can see the excel sheet, after first month principle is $ 149,950.50 and after second month it is $149,900.69 .

In ΔCDE, the measure of ∠E=90°, the measure of ∠C=70°, and DE = 12 feet. Find the length of CD to the nearest tenth of a foot

Radda [10]

Answer:

$CD = 4.4ft$

Step-by-step explanation:

Given

$DE = 12$

$\angle C = 70^\circ$

Required

Find CD

This question is represented with the attached triangle

To solve CD, we make use of tan formula.

$tan(70) = \frac{DE}{CD}$

Substitute 12 for DE

$tan(70) = \frac{12}{CD}$

Make CD the subject

$CD = \frac{12}{tan(70)}$

$CD = \frac{12}{2.7475}$

$CD = 4.4ft$ --- approximated

Determine the x- and the y-intercepts of these graphs. a) y = x-2

Ivanshal [37]

Answer:

y-intercept = (0, -2)

x-intercept = (2, 0)

Step-by-step explanation:

The y-intercept is the value of y when x = 0. Therefore, Given the linear equation, y = x - 2:

Let x = 0:

y = 0 - 2

y = -2.

Therefore, the y-intercept of the linear equation, y = x - 2 is (0, -2).

The x-intercept is the value of x when y = 0.

Therefore, let y = 0:

y = x - 2

0 = x - 2

Isolate x by adding 2 to both sides of the equation:

0 + 2 = x - 2 + 2

2 = x

Therefore, the x-intercept is (2, 0).
