Answer:

x(4 + 4) + 16 = -32

Step-by-step explanation:

-6 times 4 is -24 so then you add -24 + -24 and get -48. Then if you add a positive 16 to the -48 you get -32.

Answer:

x=4

Explanation:

3x+x−2x+8=3x+x

Step 1: Simplify both sides of the equation.

3x+x−2x+8=3x+x

3x+x+−2x+8=3x+x

(3x+x+−2x)+(8)=(3x+x)(Combine Like Terms)

2x+8=4x

2x+8=4x

Step 2: Subtract 4x from both sides.

2x+8−4x=4x−4x

−2x+8=0

Step 3: Subtract 8 from both sides.

−2x+8−8=0−8

−2x=−8

Step 4: Divide both sides by -2.

−2x−2=−8−2

Answer:

y = (x - 2)(x + 1)(x + 3)

Step-by-step explanation:

horizontal intercepts at x = 2, -1, -3

->  y = 0 when x = 2, x = -1, and x = -3

Think x minus what equals y?

1. y is 0 and x is 2 -> 0 = (2 - 2) -> y = (x - 2)

2. y is 0 and x is -1 -> 0 = (-1 - (-1)) -> y = (x + 1)

3. y is 0 and x is -3 -> 0 = (-3 - (-3)) -> y = (x - 3)

so the equation is y = (x - 2)(x + 1)(x + 3)

since y = 0 when x = 2, x = -1, and x = -3

We want to find a polynomial given that we know its roots.

We will get:

p(x) = x^3 + 2*x^2 - 5*x - 6

-------------------------------------

A polynomial with the roots {x₁, x₂, ..., xₙ} and a leading coefficient A, we can write it as:

p(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)

Here we know that the roots (horizontal intercepts) are {2, -1 , -3} but we do not know the leading coefficient, so we will use A = 1.

Then the polynomial is:

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

Expanding that we get:

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

p(x) = x^3 + 2*x^2 - 5*x - 6

This is a possible equation for the polynomial with the given horizontal intercepts.

The expression x³ + 2x represents the sum of the cube of a number and two times the number "x."

"the sum of the cube of a number and two times the number."

Let "x" represent the unknown number.

Express the given in algebra form as x³ + 2x.

To calculate the value of this expression for a specific value of "x," substitute the value of "x" into the expression.

Cube the number by raising it to the power of 3 (x³).

Multiply the number by 2 (2x).

Add the results

expression x³ + 2x represents the sum.

Step-by-step explanation:

Answer: the area of the resulting surface is π/16 [ 4√(17)  + In( 4 + √( 17)) ]

Step-by-step explanation:

Given that;

y = e^(-4x),  x ≥ 0

then, dy/dx = -4e^(-4x)

now, √( 1 + (dy/dx)² ) = √( 1 + ( -4e^(-4x))²) = √( 1 + 16e^(-8x)

so the surface area of the surface obtaining by rotating the curve y = e^(-4x) on ( 0, ∞ ) about x-axis is,

S = ₀∫^∞ 2πy √( 1 + (dy/dx)² )  dx

S = ₀∫^∞ 2πe^(-4x) . √( 1 + 16e^(-8x) dx

S = 2π. ₀∫^∞ e^(-4x) . √( 1 + 16e^(-8x) dx

so LET 4e^-4x = u ⇒  -16e^(-4x) dx = du

⇒e^-4x dx = du/ -16

so whenx = 0, then u =4 and when x → ∞ then e^(-4x) → 0 so u →0

therefore

S = 2π ₄∫⁰ √(1 + u²) . du/-16

= π/8 ₀∫⁴ √(1 + u²) . du

= π/8 [ u/2√(1 + u²)  + 1/2 In ( u + √( 1 + u²) ]₀⁴

WE MAKE USE OF

∫√( a² + u²) du = u/2√(a² + u²) + a²/2 In ( u + √( a² + u²)) + C

so

= π/8 [ 4/2√(1 + 16)  + 1/2 In ( 4 + √( 1 + u16 ]

= π/8 [ 2√(17)  + 1/2 In ( 4 + √( 17)) ]

= π/16 [ 4√(17)  + In( 4 + √( 17)) ]

therefore the area of the resulting surface is π/16 [ 4√(17)  + In( 4 + √( 17)) ]

Given parameters:

Net worth of Cesar = 8250.63

Liabilities = 3222.35

Unknown:

Cesar's asset = ?

Solution:

A person's net worth is their Assets minus liability;

             Net worth  = Assets - Liabilities

  Assets  = Net worth + Liabilities

              For Cesar;

 Assets  = 8250.63 + 3222.35 = 11472.98

Cesar's assets is  11472.98
