What is the correct factorization of x^2 - 2x - 15?

iragen [17]

Answer:

option b

Step-by-step explanation:

${x}^{2} - 2x - 15$

${x}^{2} - 5x + 3x - 15 = 0$

$x(x - 5) + 3(x - 5) = 0$

$(x - 5)(x + 3) = 0$

x = -3 (Not possible)

x = 5

So, x = 5

Find the equation of the line that has a slope of 1 and passes through the point (-2,11).

Lyrx [107]

Point-slope form is y-y1=m(x-x1)

m=1
y1=11
x1=-2

y-11=1(x-(-2)

The water level, measured in feet above mean sea level, of Lake Lanier in Georgia, USA, during 2012 can be modeled by the functi

FrozenT [24]

Answer:

May 4th, 2012.

Step-by-step explanation:

The highest level can be found with the help of the First Derivative and Second Derivative Tests. First and second derivatives of the function are, respectively:

$l'(t) = 0.04323\cdot t^{2}-0.8354\cdot t +2.703$

$l''(t) = 0.08646\cdot t - 0.8354$

The First Derivative Tests consists on equalizing the first derivative to zero and finding the critical points.

$0.04323\cdot t^{2}-0.8354\cdot t +2.703 = 0$

Roots are $t_{1} \approx 15.672$ and $t_{2} \approx 4.077$ . just the second root offer a realistic solution and is test by the second derivative.

$l''(4.077) = -0.482$ (which leads to a maximum).

Given that a year has 365 days or 12 months, the highest water level occurs at day:

$n = \frac{4.077}{12} \cdot (365\,days)$

$n \approx 124$ (May 4th).

Factor x3 + x2 + x + 1 by grouping. What is the resulting expression?

Scilla [17]

To factor by grouping, you group up the 1st 2 terms together and the last 2 terms together and then factor those pieces.

(x^3 + x^2) + (x + 1)
x^2(x + 1) + 1(x +1) - now factor out the (x + 1)
(x + 1)(x^2 + 1) - final answer
