There is a lightning rod on top of a building. From a location 500 feet from the base of the building, the angle of elevation to the top of the building Is measured to be 36 degrees. From the same location, the angle of elevation to the top of the lightning rod is measured to be 38 degrees. Find the height of the lightning rod. Round to the nearest foot.

Answers

Hello!

The answer is:

The height of the  lightning rod is 27.4 feet.

Why?

To solve the problem, we need to use the given information about the two points of observation, since both are related (both finish and start at the same horizontal distance) we need to write to equations in order to establish a relationship.

So, writing the equations we have:

We know that the angle of elevation from the base of the buildings is 36°

Also, we know that from the same location, the angle of elevation to the top of the lightning rod is 38°.

Using the information we have:

To the top of the building:

[tex]tan(\alpha )=\frac{DistanceToTheTopOfTheBuilding}{BuildingBase}\\\\tan(36\°)=\frac{DistanceToTheTopOfTheBuilding}{BuildingBase}[/tex]

To the top of the lightning rod:

[tex]tan(\alpha )=\frac{DistanceToTheTopOfTheLightningRod}{BuildingBase}\\\\tan(38\°)=\frac{DistanceToTheTopOfTheLightningRod}{BuildingBase}[/tex]

Now, isolating we have:

[tex]tan(36\°)=\frac{DistanceToTheTopOfTheBuilding}{BuildingBase}\\\\DistanceToTheTopOfTheBuilding=tan(36\°)*BuildingBase \\\\DistanceToTheTopOfTheBuilding=tan(36\°)*500feet=363.27feet[/tex]

Also, we have that:

[tex]tan(38\°)=\frac{DistanceToTheTopOfTheLightningRod}{BuildingBase}\\\\DistanceToTheTopOfTheLightningRod=tan(38\°)*BuildingBase\\\\DistanceToTheTopOfTheLightningRod=tan(38\°)*500feet=390.64feet[/tex]

Therefore, if we want to calculate the height of the lightning rod, we need to do the following:

Let "x" the distance to the top of the building and "y" the distance to the top of the lightning rod, so:

[tex]LightningRodHeight=y-x=390.64feet-363.27feet=27.37feet[/tex]

Rounding to the nearest foot, we have:

[tex]LightningRodHeight=y-x=390.64feet-363.27feet=27.37feet=27.4feet[/tex]

Hence, the answer is:

The height of the lightning rod is 27.4 feet.

Have a nice day!

Final answer:

To find the height of the lightning rod, create two right triangles using the tangent function and the given angles of elevation. Use the distance from the base to the location as the base of both triangles. Calculate the height of the building and the height of the lightning rod separately using trigonometry.

Explanation:

To find the height of the lightning rod, we can use the concept of trigonometry and create a right triangle with the base of the triangle as the distance from the base of the building to the location, the height of the building as the vertical side of the triangle, and the angle of elevation to the top of the building as one of the acute angles. Using the tangent function, we can calculate the height of the building to be approximately 287 feet. Next, we can create another right triangle with the same base the height of the lightning rod as the vertical side, and the angle of elevation to the top of the lightning rod as one of the acute angles. Again, using the tangent function, we can calculate the height of the lightning rod to be approximately 310 feet. Therefore, the height of the lightning rod is approximately 310 feet.

Answer: Here...

Step-by-step explanation:

Mean: The average of the numbers so add them up then divide by how many numbers you added

Median: The middle number of the numbers in numerical order

Mode: The number that is repeated the most often

Range: The smallest number subtracted from the larger number

Outlier: A data point or observation that is not with the others so basically the odd one out

Hope this helps Brainliest plz

Mean : The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Median: The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Mode: The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.

Range: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Outlier: A point that falls outside the data set's inner fences is classified as a minor outlier, while one that falls outside the outer fences is classified as a major outlier.

b.)the prism because it has approximately 14.1 in.3 less wasted space than the cylinder.
c.)the cylinder because it has approximately 11.6 in.3 less wasted space than the prism.
d.)the cylinder because it has approximately 14.1 in.3 less wasted space than the prism.

Answers

Answer:

Option c.) the cylinder because it has approximately 11.6 in.3 less wasted space than the prism.

Step-by-step explanation:

step 1

Find the volume of one ball

The volume of the sphere is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

we have

[tex]r=1.5\ in[/tex]

[tex]V=\frac{4}{3}(3.14)(1.5)^{3}=14.13\ in^{3}[/tex]

therefore

The volume of two balls is

[tex](2)*14.13=28.26\ in^{3}[/tex]

step 2

Find the volume of the cylinder

The volume of the cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

we have

[tex]r=1.5\ in[/tex]

[tex]h=1.5*4=6\ in[/tex]

substitute

[tex]V=(3.14)(1.5)^{2}(6)=42.39\ in^{3}[/tex]

therefore

The wasted space with the cylinder is equal to

[tex]42.39\ in^{3}-28.26\ in^{3}=14.13\ in^{3}[/tex]

step 3

Find the volume of the square prism

The volume of the square prism is equal to

[tex]V=b^{2}h[/tex]

we have

[tex]b=1.5*2=3\ in[/tex]

[tex]h=1.5*4=6\ in[/tex]

substitute

[tex]V=(3)^{2}(6)=54\ in^{3}[/tex]

therefore

The wasted space with the prism is equal to

[tex]54\ in^{3}-28.26\ in^{3}=25.74\ in^{3}[/tex]

step 4

Find the difference of the wasted space

[tex]25.74\ in^{3}-14.13\ in^{3}=11.61\ in^{3}[/tex]

Answer:

C. the cylinder because it has approximately 11.6 in.3 less wasted space than the prism.

Step-by-step explanation:

if you find the volumes of both shapes and subtract the volumes of the two balls and then subtract the two remaining values you get a difference of 11.6 inches. This makes the cylinder smaller and therefore uses less space.

The lengths of green beans for sale at a supermarket are normally distributed with a mean of 11.2 centimeters and a standard deviation of 2.1 centimeters. Consider a bag of 150 green beans.

How many green beans will be 13 centimeters or shorter?

Answers

Answer:

121

Step-by-step explanation:

First, we find the z-score for 13 cm:

z = (x - μ) / σ

z = (13 - 11.2) / 2.1

z = 0.86

Next, we use a calculator or a z-score table to find P(x<0.857).

P(x<0.86) = 0.8051

So the number of green beans in a bag of 150 less than or equal to 13 cm is:

0.8051 * 150

121

The number of green beans that is 13 centimeters or shorter will be 121. Then the correct option is C.

What is the z-score?

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

The z-score is given as,

z = (13 - 11.2) / 2.1

z = 1.8 / 2.1

z = 0.587

The number of green beans that is 13 centimeters or shorter will be given as,

⇒ 150 x P(z ≤ 0.587)

⇒ 150 x 0.8023

⇒ 121

Thus, the correct option is C.

What is the length of a diagonal of a cube with a side length of 10 cm? 200 cm 210cm 300 cm 320cm

Answers

Answer:

The length of the diagonal of the cube = √(3 × 10²) = √300 cm

Step-by-step explanation:

* Lets revise the properties of the cube

- It has six equal faces all of them are squares

- It has 12 vertices

- The diagonal of the cube is the line joining two vertices in opposite

 faces (look to the attached figure)

- To find the length of the diagonal do that:

# Find the diagonal of the base using Pythagoras theorem

∵ The length of the side of the cube is L

∵ The base is a square

∴ The length of the diagonal d = √(L² + L²) = √(2L²)

- Now use the diagonal of the base and a side of a side face to find the

 diagonal of the cube by Pythagoras theorem

∵ d = √(2L²)

∵ The length of the side of the square = L

∴ The length of the diagonal of the cube = √[d² + L²]

∵ d² = [√(2L²)]² = 2L² ⇒ power 2 canceled the square root

∴ The length of the diagonal of the cube = √[2L² + L²] = √(3L²)

* Now lets solve the problem

∵ The length of the side of the square = 10 cm

∴ The length of the diagonal of the cube = √(3 × 10²) = √300 cm

- Note: you can find the length of the diagonal of any cube using

 this rule Diagonal = √(3L²)

[tex] S = 2,304\pi ~m^2 [/tex]

Answer: First choice V = 18,432π m^3; S = 2,304π m^2

Correct  Option 2: The volume of the sphere is 972π cm³ and its surface area is 324π cm²

Volume: V = (4/3)πr³Surface Area: S = 4πr²

Given the radius (r) of the sphere is 9 centimeters:

Volume: V = (4/3)π(9)³ = (4/3)π(729) = 972π cm³Surface Area: S = 4π(9)² = 4π(81) = 324π cm²

Hence, the volume of the sphere is 972π cm³ and the surface area is 324π cm².

[tex]s(x) \times t(x) = (2 {x}^{2} + 3x - 4) \times (x + 4) \\ = 2 {x}^{3} + 3 {x}^{2} - 4x + 8 {x}^{2} + 12x - 16 \\ = 2 {x}^{3} + 11 {x}^{2} + 8x - 16[/tex]

Answer:  A) 2x³ + 11x² + 8x - 16

Step-by-step explanation:

s(x) · t(x) = (x + 4)(2x² + 3x - 4)

             = x(2x² + 3x - 4) + 4(2x² + 3x - 4)

             =   2x³ + 3x² - 4x  + 8x² + 12x - 16

             =   2x³  + (3x² + 8x²) + (- 4x + 12x) - 16

             =  2x³          + 11x²              + 8x      - 16

ANSWER

x coordinates of the intersection points

EXPLANATION

The given system of equations is:

[tex]y = 4 {x}^{2} - 3x + 6[/tex]

[tex]y = 2 {x}^{4} - 9 {x}^{3} + 2x[/tex]

We want to use the graph of these functions to solve

[tex] 4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x [/tex]

The point of the intersection of the graph gives the solution to the simultaneous equation above.

Hence the x-coordinates of the intersection points gives the solution set of

[tex]4 {x}^{2} - 3x + 6 = 2 {x}^{4} - 9 {x}^{3} + 2x [/tex]

The last choice is correct.

Step-by-step explanation:

Charlie can invest $8,000 at 8.5% interest for 15 days. How much interest will he earn on his investment if the interest is compounded daily?

Answers

Answer:

$27.99 interest.

Step-by-step explanation:

Use the formula for Compound interest = P(1 + r/n)^t  . Here n = 365 (number of days in a year), r = annual rate as a decimal and t = the number of days, P = 8000.

Amount after 15 days = 8,000(1 + 0.085/365)^15

= $8027.99.

Final answer:

Charlie will earn interest on his $8,000 investment at an 8.5% annual rate, compounded daily, for 15 days. The interest can be calculated using the formula for compound interest and will likely result in slightly more interest earned than if it was calculated using simple interest.

Explanation:

Charlie can invest $8,000 at 8.5% interest for 15 days. To calculate the interest earned with daily compounding, we use the formula A = P(1 + r/n)nt, where A is the amount of money accumulated after n years, including interest, P is the principal amount ($8,000), r is the annual interest rate (8.5%), n is the number of times that interest is compounded per year (365, since it's daily), and t is the time the money is invested in years (15/365, because here t is 15 days).

By substituting the values into the formula we get: A = $8,000(1 + 0.085/365)365*(15/365). After computing this, we find the new amount that Charlie will have after the 15 days are over. The interest earned is then found by subtracting the principal ($8,000) from this new amount.

Note that compound interest, especially when compounded frequently, can lead to greater earnings than simple interest. This difference is more pronounced with larger amounts and over longer periods, as shown by the reference provided where compound interest for a $100 investment over three years was $0.76 more than with simple interest.

Answer:

The equation of this line is therefore    y = 2x + 3.

Step-by-step explanation:

this line passes thru the points (0, 3) and (3, 9).  As we move from  (0, 3) to (3, 9), x increases by 3 and y increases by 6.  Thus, the slope of this line is

m = rise / run = 6/3, or m = 2.  Inserting the known info (m = 2, x = 0, y = 3) into y = mx + b, we get:  3 = 2(0) + b, so we see that b = 3.

The equation of this line is therefore    y = 2x + 3.

Write the complex number in the form a + bi.
3(cos 60° + i sin 60°)

Answers

Answer:

The complex number in the form of a + b i is 3/2 + i √3/2

Step-by-step explanation:

* Lets revise the complex number in Cartesian form and polar form

- The complex number in the Cartesian form is a + bi

-The complex number in the polar form is r(cosФ + i sinФ)

* Lets revise how we can find one from the other

- r² = a² + b²

- tanФ = b/a

* Now lets solve the problem

∵ z = 3(cos 60° + i sin 60°)

∴ r = 3 and Ф = 60°

∵ cos 60° = 1/2

∵ sin 60 = √3/2

- Substitute these values in z

∴ z = 3(1/2 + i √3/2) ⇒ open the bracket

∴ z = 3/2 + i √3/2

* The complex number in the form of a + b i is 3/2 + i √3/2

Answer:

3/2 + (3sqrt(3))/2 i

Step-by-step explanation:

On the unit circle cosine and sine 60 degrees can be found in the first quadrant. With the correct measures. Once located, (1/2, sqrt(3)/2), multiply those numbers by 3. Don't forget to include i.

3(1/2 + sqrt(3)/2 * i)

= 3/2 + (3sqrt(3))/2 i
