. Write the quadratic equation in factored form. Be sure to write the entire equation. x^2 - 5x - 24 = 0

Viefleur [7K]

Answer:

$(x+3)(x-8)=0$

Step-by-step explanation:

First, write out the equation as it is given in the problem:

$x^{2}-5x-24=0$

Now, you have to split up the "-5x" to get to factored form. The way to do this is to look for <em>the factors of "a" times "c" that sum to "b"</em>:

So, in this problem, a=1, b=-5, and c=-24. So, find the factors of (1*-24) that sum to (-5). To clarify, (1*-24)=-24, so you have to find factorsof -24 that sum to -5.

Let's write out a list of factors.

$1,-24---1+-24=-23no\\-1,24---1+24=23no\\2,-12---2+-12=-10no\\-2,12----2+12=10no\\3,-8---3+-8=-5yes$

Therefore, our two factors will be 3x and -8x.

Now, let's rewrite our equation with these new factors in place of the -5x:

$x^{2}-5x-24=0\\x^{2}+3x-8x-24=0$

Next, find your factored expressions:

$x^{2}+3x-8x-24=0\\(x^{2}+3x)(-8x-24)=0\\$

Take the GCF from each set of parenthesis:

$x(x+3)-8(x+3)=0$

The GCFs that you took out will become your second in the set for factorde form. It will be written as "x-8".

Therefore, your equation in factored form will be:

$(x+3)(x-8)=0$

Bernice uses the equation C = 2h + 8 to find the total cost, C, in dollars, of renting a boat for h hours. If Bernice does not s

Rzqust [24]

Answer:

A

Step-by-step explanation:

Since she's not spending more than $32, the equation is 2h + 8 ≤ 32.

Isolate h to find the maximum number of hours she can rent the boat:

2h + 8 ≤ 32

First, subtract 8 from both sides.

2h ≤ 16

Then divide both sides by 2.

h ≤ 8

h, the number of hours, must be less than or equal to 8, so 8 is the maximum number of hours Bernice can rent the boat for.

Use Newton's method with initial approximation x1 = −2 to find x2, the second approximation to the root of the equation x3 + x +

rjkz [21]

Answer:

The value of $x_2=-1.6923$ .

Step-by-step explanation:

Consider the provided information.

The provided formula is $f(x)=x^3+x+6$

Substitute $x_1=-2$ in above equation.

$f(x_1)=(-2)^3+(-2)+6$

$f(x_1)=-8-2+6$

$f(x_1)=-4$

Differentiate the provided function and calculate the value of $f'(x_1)$

$f'(x)=3x^2+1$

$f'(x)=3(-2)^2+1$

$f'(x)=13$

The Newton iteration formula: $x_2=x_1-\frac{f(x_1)}{f'(x_1)}$

Substitute the respective values in the above formula.

$x_2=-2-\frac{(-4)}{13}$

$x_2=-2+0.3077$

$x_2=-1.6923$

Hence, the value of $x_2=-1.6923$ .
