A 381 foot cable runs from the top of a radio tower to a skate in the ground. If it hits the ground 167 feet from the base of the tower , what is the angle of elevation that is makes with the ground?

Answers

Answer 1

Answer:

64°

Step-by-step explanation:

Using Pythagoras rule :

Cosθ = adjacent / hypotenus

Adjacent = 167

Hypotenus = 381

Cosθ = 167 / 381

Cosθ = 0.4383202

θ = Cos^-1(0.4383202)

= 64.003

Hence, angle of elevation = 64°

2√5

Step-by-step explanation:

The triangle that's shown on the page is a special isosceles right triangle with angle measures of 45° - 45° - 90°

Since one of the side length that sees 45° angle measure is 2√5 the other also has to be equal to this value so the answer is 2√5

A projector displays an image on a wall. The area (in square feet) of the projection is represented by x^2-8x+15
a. write a binomial that represents the height of the projection
b. find the perimeter of the projection when the height of the wall is 8 feet​

Answers

Answer:

a. (x - 5) ftb. 16 ft

Step-by-step explanation:

The area given:

x² - 8x + 15

a. The height is the factor of the area:

x² - 8x + 15 = x² - 3x - 5x + 15 = x(x - 3) - 5(x - 3) = (x - 3)(x - 5)

The width is x - 3, so the height is x - 5

b. The perimeter formula:

P = 2(x - 3 + x - 5) = 2(2x - 8) = 4x - 16

The height of the wall is 8 ft:

x = 8

The perimeter is:

P = 4*8 - 16 = 32 - 16 = 16 ft

6. The scatter plot shows the median household income, x, in thousands of dollars, and

the number of adults per 1,000 people with bachelor's degrees, y, of 50 U.S. states.

The line y = 4.08x + 63.13 is a good fit for this data.

Answers

The line y = 4.08x + 63.13 is a good fit for this data because it accurately represents the positive relationship between median household income and the number of adults with bachelor's degrees in the 50 U.S. states.

Given that a scatter plot of median household income x and the number of adults per 1,000 people with bachelor's degrees y for 50 U.S. states. The line y = 4.08x + 63.13 is suggested to be a good fit for this data.

To understand why this line is a good fit, to consider its equation. In this case, y represents the number of adults per 1,000 people with bachelor's degrees, and x represents the median household income in thousands of dollars.

The equation of the line is y = 4.08x + 63.13. This means that for every increase of $1,000 in median household income, the number of adults with bachelor's degrees increases by 4.08 per 1,000 people. The intercept of the line is 63.13, which represents the number of adults with bachelor's degrees when the median household income is $0.

By analyzing the scatter plot, we can see that the points are roughly linear and show a positive correlation between median household income and the number of adults with bachelor's degrees. The line represents the best fit for this data because it minimizes the distance between the line and the points on the scatter plot.

Hence, the line y = 4.08x + 63.13 is a good fit for this data because it accurately represents the positive relationship between median household income and the number of adults with bachelor's degrees in the 50 U.S. states.

Step-by-step explanation:

Answer:

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6, and the correct answer 6, 8, and 10.

Step-by-step explanation:

Jared wanted three consecutive even integers, whose sum is 4 times the first integer.

He let k represent the first integer and wrote:

[tex]k+(k+1)+(k+2)=4k[/tex]

We can solve this first. Combine like terms:

[tex]3k+3=4k[/tex]

So:

[tex]k=3[/tex]

This means that our sequence will be 3, 4, and 5, which is not correct since we have odd integers.

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation*:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6**, and the correct answer 6, 8 , and 10.

To verify, 6 + 8 + 10 = 24.

And 6(4) = 24, so our answer is correct.

**To solve, we can combine like terms:

[tex]3k+6=4k[/tex]

So:

[tex]k=6[/tex]

*The reason we use (k + 2) instead of (k + 1) is because (if k is an even number), then adding 2 guarantees another even number. If we added only 1, we will get odd numbers.

HIJK is a triangle based pyramid. The base HIJ is an equilateral triangle with side 10cm. The volume of the pyramid is 300cm^3. Calculate the perpendicular height, h, of the pyramid.

Answers

Answer:

20.78 cm^3 to the nearest hundredth.

Step-by-step explanation:

Volume = 1/3 * a * h    where a = area of triangular base and h = the height.

The area of the triangle

= 1/2 * base * height

Its height = √(10^2-5^2)

= √75.

So its area = 1/2 * 10 * √75

= 5√75

So for the pyramid we have:

300 = 1/3 *  5√75 * h

h = 300 /  (1/3 *  5√75)

= 20.78 cm^3.
