[tex]4x+4-\frac{4}{x+6}[/tex]

Step-by-step explanation:

[tex]\frac{\left(4x^2+28x+20\right)}{\left(x+6\right)}[/tex]

Step 1: Divide

[tex]=4x+\frac{4x+20}{x+6}[/tex]

Step 2: Divide again

[tex]=4x+4+\frac{-4}{x+6}[/tex]

Step 3: Simplify

percentage of lightbulb replacement requests =  34.15 %

Step-by-step explanation:

According to Empirical Rule

interval                                                          %

μ  ±  σ            55  ±  4     ( 51 ; 59 )              68.3

A, x > 1

Step-by-step explanation:

The point starts at 1 and shows that x is greater by pushing forward the number line more to the right. The circle is also hallow which just means greater than or just less than in this case its showing x is greater than 1 .

Answer:

Area of the sector = 94.25 in²

Step-by-step explanation:

From the picture attached,

Length of the radius of the circle = 12 in.

m(arc BC) = [tex]\frac{\pi }{6}[/tex]

m(arc CD) = [tex]\frac{\pi }{4}[/tex]

Therefore, m(arc BD) = m(arc BC) + m(arc CD)

m(arc BD) = [tex]\frac{\pi }{6}+\frac{\pi }{4}[/tex]

                 = [tex]\frac{5\pi }{12}[/tex]

Since, area of a sector with central angle 'θ' is given by,

Area of the sector = [tex]\frac{\theta}{2\pi }(\pi r^2)[/tex]

By substituting the measures in the given formula,

Area of sector BAD = [tex]\frac{\frac{5\pi }{12}}{2\pi }(\pi )(12)^2[/tex]

                                  = [tex]\frac{5}{24}(\pi )(144)[/tex]

                                  = [tex]30\pi[/tex]

                                  = 94.25 in²

Answer:

Angle of elevation of the airplane = 17.46 degrees

Step-by-step explanation:

From the picture attached,

An airplane is flying at an altitude of 1500 ft at point A.

Runway starts from point B from which distance of the airplane is 5000 ft.

Now we apply sine rule in the given triangle ABC to measure the angle θ.

sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sinθ = [tex]\frac{AC}{AB}[/tex]

       = [tex]\frac{1500}{5000}[/tex]

[tex]\theta=\text{sin}^{-1}(\frac{3}{10})[/tex]

[tex]\theta=17.46[/tex] degrees

Answer:

1.2 ft

Step-by-step explanation:

Answer:

all you will do is is to get the surface area of each object

triangles each equals 8.64 squared cm

the rectangle equals 172.8 squared cm

Step-by-step explanation:

triangle= 0.5×4.8×3.6=8.64 squared cm

rectangle=12×14.4= 172.8 squared cm

the prism of all will be (8.64)(2)+172.8=190.08 squared cm

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the equation provided I have graphed it in the image below. There was no value provided for f, therefore, an input value of 1 was passed to it. As you can see from the graph, the equation graphs as an inclined line that revolves around -2 as its x-intercept. This is because the -1.2 changes the value of the x-coordinate when g(x) is 0. Instead of it being 2 it is -2, and therefore all other values revolve around this number.

The graph of the function g(x) = -1/2f(x+2) is given below.

To graph the function g(x) = -1/2f(x+2), we need to first understand the properties of the function f(x) and then apply the necessary transformations.

Given that the function f passes through the points (3, 0) and (4, 2), we can determine the slope of the line using the formula:

slope = (change in y) / (change in x) = (2 - 0) / (4 - 3) = 2 / 1 = 2

Therefore, the slope of the function f is 2.

Now, let's apply the transformations to the function f(x) to graph g(x). The given function g(x) = -1/2f(x+2) involves two transformations:

Horizontal Translation: The function f(x) is shifted horizontally to the left by 2 units because of the term (x+2) inside the function. This means that the x-coordinates of the points on the graph will be reduced by 2 units.

Vertical Scaling: The function f(x) is scaled vertically by a factor of -1/2 because of the coefficient -1/2 in front of f(x). This means that the y-coordinates of the points on the graph will be multiplied by -1/2.

Therefore, the function g(x) is g(x) = -x + 1.

Given:

P(x) is a 2nd degree polynomial.

[tex]P(1)=0,\ P(2)=3,\ P(-3)=0[/tex]

To find:

The polynomial P(x).

Solution:

If P(x) is a polynomial and P(c)=0, then c is a zero of the polynomial and (x-c) is a factor of polynomial P(x).

We have, [tex]P(1)=0,\ P(-3)=0[/tex]. It means 1 and -3 are two zeros of the polynomial P(x) and (x-1) and (x+3) are two factors of the polynomial P(x).

So, the required polynomial is defined as:

[tex]P(x)=a(x-1)(x+3)[/tex]          ...(i)

Where, a is a constant.

We have, [tex]P(2)=3[/tex]. So, substituting [tex]x=2,\ P(x)=3[/tex] in (i), we get

[tex]3=a(2-1)(2+3)[/tex]

[tex]3=a(1)(5)[/tex]

[tex]3=5a[/tex]

[tex]\dfrac{3}{5}=a[/tex]

Putting [tex]a=\dfrac{3}{5}[/tex] in (i), we get

[tex]P(x)=\dfrac{3}{5}(x-1)(x+3)[/tex]

Therefore, the required polynomial is [tex]P(x)=\dfrac{3}{5}(x-1)(x+3)[/tex].

so the united states invasion of afghanistan occurred after the September 11 attacks in late 2001, supported by close US allies. The conflict is also known as the US war in Afghanistan. the goal was to dismantle al-Qaeda and deny it a safe base of operations in Afghanistan by removing the Taliban from power.

An easy way to find the surface area of a composite figure is to divide the composite figure up into smaller shapes whose area it is easier to find. It is best to divide a composite figure up into a figure composed of many triangles and rectangles. Then, one will find the area of each of these smaller figures and add the value up to find the total surface area of the composite figure.

The center of the circle would be (5,-8)

This is because you inverse the sign within the equation for the x/y coordinate part of it. Therefore, for this question:

(x-5)^2+(y+8)^2 = 121

The center would be (5,-8), since there is (x-5) and (y+8).

The radius of the circle would be 11

This is because within the equation for the circle, the finishing number is the radius squared. This means that if you square root this finishing number, you would get the radius. So with this question:

(x-5)^2+(y+8)^2 = 121

By doing √121, you would get 11 as the radius.

Answer:

A. 4%

Step-by-step explanation:

We can find out the total weight in the beginning by adding 240+10 which is 250

Then we divide 10/250 or we can multiply both sides by 4 to move the denominator to the 1000th which is 40/1000 and remove a 0 from both sides which makes 4/ 100 or 0.04 which is 4%
