Answer:The answer is D. .116 fr Plato

The probability that If a person is selected at random the person is taller than 180 centimeters and has black hair is 0.116.

The probability helps us to know the chances of an event occurring.

[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

The number of people who are having black hair and are taller than 180 cm is 29. And the total number of employees in the company is 250. Therefore, the probability that the person is taller than 180 centimeters and has black hair can be written as,

[tex]\rm Probability=\dfrac{\text{Number of people with black hair and taller than 180 cm}}{\text{Total number of employees in the company}}\\\\\\Probability = \dfrac{29}{250} = 0.116[/tex]

Thus,  the probability that If a person is selected at random the person is taller than 180 centimeters and has black hair is 0.116.

Answer:

16682.7 cm³

Step-by-step explanation:

The total volume is the volume of the cone plus half the volume of a sphere:

V = ⅓ π r² h + ½ (4/3 π r³)

V = ⅓ π r² h + ⅔ π r³

V = ⅓ π r² (h + 2r)

Given that r = 4.15 cm and h = 10.2 cm:

V = ⅓ π (4.15)² (10.2 + 2×4.15)

V ≈ 333.65

The volume needed for 50 cones is therefore:

50V ≈ 16682.7 cm³

Step-by-step explanation:

The graph will be a straight line that starts at the origin and rises diagonally to the right with a slope of 2. The correct graph id graph 2

Since each light panel holds two light bulbs, the number of light bulbs, y, is directly proportional to the number of light panels, x. This means that as the number of light panels increases, the number of light bulbs will also increase in a linear manner.

The relationship can be represented by the equation:

y = 2x

Where y represents the number of light bulbs and x represents the number of light panels.

The graph representing the relationship between the number of light panels, x, and the number of light bulbs, y, will be a straight line.

In this case, the line will have a positive slope of 2 since each light panel holds two light bulbs. This means that for every increase of one unit in the number of light panels, the number of light bulbs will increase by two units.

The graph will pass through the origin (0, 0) since when there are no light panels (x = 0), there will be no light bulbs (y = 0).

As x increases, y will also increase in a linear manner. The line will extend indefinitely in the positive direction in both the x-axis and y-axis, indicating that the relationship continues without any upper limit.

Visually, the graph will be a straight line that starts at the origin and rises diagonally to the right with a slope of 2.

Answer:

Step-by-step explanation:

I take it that the base of the log is 4.

So the question can be written as

log_4 [(x+2)/(x + 3)] = -1

If you take the antilog of this, you get

(x + 2)/(x+3) = 4^-1 = 1/4

Now Cross Multiply

4*(x + 2) = 1*(x + 3)               Remove  the brackets on both sides

4x + 8 = x + 3                       subtract x from both sides.

4x - x + 8 = x - x + 3             Combine

3x + 8 = 3                             Subtract 8 from both sides

3x = 3 - 8                              Combine

3x = - 5                                 Divide by 3

Hope this helps!

The ratio of baseballs to the total number of balls in the storage room is 1:5. For every one baseball, there are five balls of any type.

We are looking for the ratio of baseballs to total balls. We find the total by adding the number of each type of balls: 10 (baseballs) + 4 (basketballs) + 12 (softballs) + 4 (soccer balls) + 20 (tennis balls) = 50 balls in total.

Now that we know the total, we can find the ratio of baseballs to the total amount of balls. There are 10 baseballs from a total of 50 balls. Thus, the ratio would be 10:50. Simplified, this ratio would be 1:5. This means for every one baseball, there are five balls of any type.

The answer is:

The domain of the function is all the real numbers except the number 13:

Domain: (-∞,13)∪(13,∞)

This is a composite function problem. To solve it, we need to remember how to composite a function. Composing a function consists of evaluating a function into another function.

Composite function is equal to:

[tex]f(g(x))=(f\circ} g)(x)[/tex]

So, the given functions are:

[tex]f(x)=x+7\\\\g(x)=\frac{1}{x-13}[/tex]

Then, composing the functions, we have:

[tex]f(g(x))=\frac{1}{x-13}+7\\[/tex]

Therefore, we must remember that the domain are all those possible inputs where the function can exists, most of the functions can exists along the real numbers with no rectrictions, however, for this case, there is a restriction that must be applied to the resultant composite function.

If we evaluate "x" equal to 13, the denominator will tend to 0, and create an indetermination since there is no result in the real numbers for a real number divided by 0.

So, the domain of the function is all the real numbers except the number 13:

Domain: (-∞,13)∪(13,∞)

Answer:

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}=\frac{sin^2(x)}{|cos(x)|}[/tex]

Step-by-step explanation:

To simplify this expression you must use the following trigonometric identities

[tex]cos(\frac{\pi}{2}-x) = sinx[/tex]     I

[tex]1-sin (x) ^ 2 = cos ^ 2(x)[/tex]      II

Remember that

[tex]\sqrt{f(x)^2} =f(x)[/tex]

Only if [tex]f(x)> 0[/tex]  for all x

If f(x) is not greater than 0 for all x then

[tex]\sqrt{f(x)^2} =|f(x)|[/tex]

Now we have the expression:

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}[/tex]

then using the trigonometric identities I and II we have to:

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}=\frac{sin^2(x)}{\sqrt{1-sin^2(x)}}\\\\\\\frac{sin^2(x)}{\sqrt{1-sin^2(x)}}= \frac{sin^2(x)}{\sqrt{cos^2(x)}}[/tex]

[tex]cos(x)[/tex] is not greater or equal than 0 for all x. So.

[tex]\frac{sin^2(x)}{\sqrt{cos^2(x)}}=\frac{sin^2(x)}{|cos(x)|}[/tex]

Finally  

[tex]\frac{cos^2(\frac{\pi}{2}-x)}{\sqrt{1-sin^2(x)}}=\frac{sin^2(x)}{|cos(x)|}[/tex]

Answer:

k = 13

smallest zero = -6

Step-by-step explanation:

f(x) is basically the function of x.

x could be any integer. f(x) is the solution of the function of x.

f(x) is defined as x² + 3x - 10

f(x) = x² + 3x - 10

Now, f(x+5) = x² + kx + 30

This statement here says that if the value of x is x+5, then the answer would be x² + kx + 30.

f(x) = x² + 3x - 10

f(x+5) = (x+5)² + 3(x+5) - 10

f(x+5) = x² + 10x + 25 + 3x + 15 - 10

f(x+5) = x² + 13x + 40 - 10

f(x+5) = x² + 13x + 30

x² + 13x + 30 = x² + kx + 30

hence, k = 13

Smallest zero = The smallest x value.

f(x+5) = x² + 13x + 30

Let's take f(x+5) = 0

x² + 13x + 30 = 0

which two numbers products give us 30 and add up to 13?

== 6 and 5

(x+6)(x+5) = 0

x+6 = 0

x = -6

x+5 = 0

x = -5

The two solutions are -6 and -5

The smallest out of these two is -6.  

Answer:

Step-by-step explanation:

Zero in on the highest power of x.  It's 4.  Thus, this polynomial is of the 4th degree.

Note:  Please use " ^ " to indicate exponentiation:

-2x^4 - x^3 + 8x^2 - 12

The equation -2x^4 - x^3 + 8x^2 = 12 is a 4th degree polynomial because the highest power of the variable is 4.

The equation given is a polynomial equation, and polynomials are classified by degree, which is the highest power of the variable. In the given equation -2x4 - x3 + 8x2 = 12, we can see that the highest power is 4, which is the degree of the x variable. Thus, this equation is a 4th degree polynomial equation.

The variable with the highest degree is used to classify the polynomial. In this case, the variable x has the highest degree, making it a 4th degree polynomial. The value of the degree helps us to understand the shape of the graph of the equation. In this case, a 4th degree polynomial could have 0, 2, or 4 real roots and the graph can have 2 turning points.

Answer:

The rock will take about 4.5 seconds to reach the river

Step-by-step explanation:

* lets study the situation of the rock

- The rock is dropped means the initial velocity is zero

- The motion is free fall under earth gravity

- The rock dropped from a bridge 320 feet above the river

- The equation of the pathway is h = -16t² + 320

- When the rock reach to the ground the height will be zero

* Now lets substitute h by zero in the equation to find t

∵ h = -16t² + 320

∵ h = 0

∴ 0 = -16t² + 320 ⇒ add 16t² to both sides

∴ 16t² = 320 ⇒ divide both sides by 16

∴ t² = 320/16 = 20

∴ t² = 20 ⇒ take √ for both sides

∴ t = √20 = 2√5 ≅ 4.5 seconds

* The rock will take about 4.5 seconds to reach the river

The final answer is D: 4.5 seconds.

let's go through the solution in more detail.

Given the equation [tex]\( h = -16t^2 + 320 \)[/tex], where [tex]\( h \)[/tex] represents the height of the rock above the river at time [tex]\( t \),[/tex] we're trying to find out when the rock reaches the river, which means its height will be 0.

So, we set [tex]\( h \)[/tex] to 0:

[tex]\[ 0 = -16t^2 + 320 \][/tex]

To solve for [tex]\( t \),[/tex] we isolate [tex]\( t \)[/tex] by moving [tex]\( -16t^2 \)[/tex] to the other side of the equation:

[tex]\[ 16t^2 = 320 \][/tex]

Now, to solve for [tex]\( t \),[/tex] we divide both sides by 16:

[tex]\[ t^2 = \frac{320}{16} \]\[ t^2 = 20 \][/tex]

To find [tex]\( t \),[/tex] we take the square root of both sides:

[tex]\[ t = \sqrt{20} \][/tex]

Now, let's simplify [tex]\( \sqrt{20} \):[/tex]

[tex]\[ \sqrt{20} = \sqrt{4 \times 5} \]\[ \sqrt{20} = \sqrt{4} \times \sqrt{5} \]\[ \sqrt{20} = 2\sqrt{5} \][/tex]

Approximately, [tex]\( \sqrt{5} \)[/tex] is around 2.24, so [tex]\( 2\sqrt{5} \)[/tex] is approximately [tex]\( 2 \times 2.24 \),[/tex] which is approximately 4.48.

So, it will take approximately 4.5 seconds for the rock to reach the river.

Therefore, the correct answer is option D: 4.5 seconds.
