In order to find the solution to this problem, you would first need to divide 54 by 3, than multiply by 4. You could also multiply 54 by the reciprocal of 3/4, which is 4/3.

The correct answer is 33 m at 252 degrees, 16.1 m at 239 degrees, and 16 m at 240 degrees. It should be noted that the angle values of 239 degrees and 240 degrees are close to the angle value obtained for the resultant vector.

Two vectors, vector A and vector B, are given with their respective magnitudes and directions. The main idea is to add the two vectors using trigonometry to obtain the resultant vector. The vectors can be represented in the form of (magnitude, angle), where the magnitude is given in meters and the angle is given in degrees. Using the law of cosines, we can add the two vectors to obtain the resultant vector as:

R² = A² + B² - 2ABcos(θB - θA)R² = (15²) + (30²) - 2(15)(30)cos(224° - 28°)R² = 225 + 900 - 2(450)(-0.882)R² = 225 + 900 + 788.4R² = 1913.4R = √(1913.4)R = 43.77 m. The direction θR of the resultant vector is:tanθR = (A sinθA + B sinθB)/(A cosθA + B cosθB)tanθR = (15 sin28° + 30 sin224°)/(15 cos28° + 30 cos224°)tanθR = 0.5905θR = tan⁻¹(0.5905)θR = 29.75° or 206.25

°However, the given answer choices are not in the same format as the answer obtained above. We can convert the answer obtained above to the format given in the answer choices as follows:43.77 m at 206.25° (rounded to 2 decimal places)Therefore, the correct answer is 33 m at 252 degrees, 16.1 m at 239 degrees, and 16 m at 240 degrees. It should be noted that the angle values of 239 degrees and 240 degrees are close to the angle value obtained for the resultant vector.

Answer:

35

Step-by-step explanation:

Angle QRS is an inscribed angle, so measure of angle QRS is half the measure of the intercepted arc, arc SPQ. Therefore arc SPQ is 125*2 = 250 degrees, and arc QRS is 360 - 250 = 110 degrees.

Angle QPS is an inscribed angle, and arc QRS is its intercepted arc. Therefore angle QPS is 110/2 = 55 degrees. Since PS is the radius of the circle, angle PQS, the angle inscribed in the semicircle, is 90 degrees. Since interior angles of the triangle QPS add up to 180 degrees, angle QSP is 180 - 90 - 55 = 35 degrees.

Angles QSP and UST are vertical angles, and by the vertical angles theorem, they are congruent. Therefore x = 35.

Answer: $18.51

Step-by-step explanation:
1015cm^3/7.95cm^3/g = 127.67g

127.67g/1000g = .128

.128*$.29 = $.037

$.037*500 = $18.51

Answer:

$1170

Step-by-step explanation:

1. We know that each steel part has a volume of 1015 cubic centimeters, and the machinist wants to make 500 of these. Then the total volume of the steel part the machinist will make will be 1015 x 500.

--> 1015 x 500

--> 507500 cubic centimeters.

2. The density of the steel part is 7.95 grams per one cubic centimeter. Then the total density of the 500 steel parts will be 507500 x 7.95.

--> 507500 x 7.95

--> 4,034,625 grams.

3. For every kilo of steel part, the cost is $0.29. We should first change the 4,034,625 gram to kilo. Since 1000 grams is a kilo, we divide 4,034,625 by 1000.

--> 4,034,625 grams / 1000 = 4034.625 kilograms.

Now we multiply 4034.625 by 0.29 to find the total cost.

--> 4034.625 x 0.29

--> 1170.04125.

Since the question specifically asked to round it to the nearest dollar, our final answer becomes $1170.

(26/26) × (25/26) × (24/26) × (23/26)

= 358800/456976

= 0.785

Hence, the probability of typing four letters with no repeated letters is 0.785.

Answer: 4 square feet per minute

Answer:

Step-by-step explanation:

substitute x = 1.5 into the function

y = - 2(1.5)² + 7(1.5) = - 2(2.25) + 10.5 = - 4.5 + 10.5 = 6

Answer:

b 16.4 ft

Step-by-step explanation:

To solve this problem using a graphing calculator, we need to plug in the value of q (which is given as 7) into the equation y = 2 csc e, and then graph the resulting equation.

First, we need to convert the angle e from degrees to radians, because the csc function takes its input in radians. We can use the conversion formula:

radians = degrees x (π/180)

So for e = 2, we have:

e (in radians) = 2 x (π/180) = 0.0349 radians

Now we can plug this value into the equation y = 2 csc e:

y = 2 csc(0.0349) ≈ 103.8 feet

This tells us that the length of the rafters needed to make the roof is approximately 103.8 feet. However, the question asks us to round to the nearest tenth of a foot, so the answer is:

y ≈ 103.8 feet ≈ 103.8 rounded to the nearest tenth of a foot

Therefore, the length of the rafters needed to make the roof for q 7" is approximately 103.8 feet, rounded to the nearest tenth of a foot.

So the correct answer is (b) 16.4 feet.

Using the graphing calculator, we find that the length of the rafters needed is approximately 16.4 feet, Therefore, the correct answer is option B, 16.4 feet.

To find the length of the rafters needed for the roof with an angle of 7 degrees, we'll use the given function y = 2 * csc(e), where e is the angle formed by the rafters and the top of the wall. Here's a step-by-step explanation:

1. Convert the angle from degrees to radians: e (in radians) = (7 degrees * π) / 180 ≈ 0.1222 radians.

2. Calculate the cosecant  (csc) of the angle e: csc(0.1222) ≈ 8.185.

3. Plug the value of csc(e) into the function: y = 2 * 8.185 ≈ 16.37.
Using a graphing calculator, we can input the function y = 2 csc e and graph it. Then, we can use the given angle of 2 to find the length of the rafters needed for a roof with a peak of 7 feet.

4. Round the length to the nearest tenth of a foot: 16.37 ≈ 16.4 feet.
When we graph the function, we can see that the length of the rafters is the distance between the x-axis and the point on the graph where y = 7.
So, the length of the rafters needed to make the roof for an angle of 7 degrees is approximately 16.4 feet (Option b).

The most general antiderivative of f(x) = (5/2)sqrt(x) + 2sec^2(x) is:

F(x) = (5/3)x^(3/2) + 2tan(x) + C

To find the most general antiderivative of the function f(x) = (5/2)sqrt(x) + 2sec^2(x), we can integrate each term separately.

The antiderivative of (5/2)sqrt(x) can be found using the power rule of integration. We add 1 to the exponent (1/2) and divide by the new exponent:

∫(5/2)sqrt(x) dx = (5/2) * (2/3)x^(3/2) + C = (5/3)x^(3/2) + C

This is a linear equation in slope-intercept form, where the slope is the cost per room, which is $10, and the y-intercept is 0, since there is no charge for zero rooms painted. The equation allows us to calculate the cost of painting any number of rooms by simply plugging in the value of x. For example, if Samuel painted 6 rooms, the equation would be y = 10(6) = $60. The y-intercept of the equation is 0, indicating that if Samuel doesn't paint any rooms, he doesn't earn any money. Thus, this equation can be used to calculate the total amount of money Samuel will earn based on the number of rooms he paints.

The normal distribution is solved and percent of steers weigh over 1225 pounds is A = 19.3 %

Given data ,

The virginia cooperative extension reports that the mean weight of yearling angus steers is 1152 pounds

Now , weights of all such animals can be described by a normal model with a standard deviation of 84 pounds

First, we need to standardize the value 1225 pounds using the formula z = (x - μ) / σ, where x is the given value, μ is the mean, and σ is the standard deviation.

z = (1225 - 1152) / 84 = 0.869

Next, we can use a standard normal distribution table or a calculator to find the area under the curve to the right of z = 0.869. The corresponding probability represents the percentage of steers that weigh over 1225 pounds.

Using a standard normal distribution table, we find that the area to the right of z = 0.869 is approximately 0.193. This means that about 19.3% of steers weigh over 1225 pounds.

Hence , about 19.3% of yearling angus steers would be expected to weigh over 1225 pounds based on the given normal model

To estimate the project's beta, we need to make assumptions and use available data. Given the information provided for a publicly traded firm in the same line of business, including the debt outstanding, number of shares, stock price per share, book value of equity per share, and the beta of equity, we can calculate an estimate of the project's beta.

The beta measures the systematic risk of an investment relative to the overall market. To estimate the project's beta, we can use the leveraged beta approach. Since the project will be financed with equity, we assume that the project's beta will be equal to the equity beta of the publicly-traded firm in the same line of business. Therefore, the estimated beta of the project would be 1.19, based on the given information.

It is important to note that this estimation relies on the assumption that the project's risk profile and systematic risk are similar to that of the publicly-traded firm used as a reference. Additionally, this approach assumes that the project is solely financed with equity and does not take into account any potential debt financing or other factors that may affect the project's beta.
