We can approach this problem by breaking down the two displacements of the ship into their respective x- and y-components and then adding them together to find the net displacement.

For the first displacement, the ship traveled 25° South of West for 250 miles. This can be broken down into an x-component and a y-component as follows:

x = 250 cos(25°) (to the west) y = -250 sin(25°) (to the south)

For the second displacement, the ship changed direction to 70° East of South and traveled 45 miles further. This can also be broken down into an x-component and a y-component:

x = 45 cos(70°) (to the east) y = -45 sin(70°) (to the south)

To find the net displacement, we can add the x-components and y-components separately:

total x = 250 cos(25°) + 45 cos(70°) total y = -250 sin(25°) - 45 sin(70°)

We can use these values to find the distance of the ship from its starting point by using the Pythagorean theorem:

distance = sqrt((total x)^2 + (total y)^2)

Substituting the values from above and evaluating:

distance = sqrt((250 cos(25°) + 45 cos(70°))^2 + (-250 sin(25°) - 45 sin(70°))^2)

distance ≈ 272.8 miles

To find the direction of the ship from its starting point, we can use the inverse tangent function to find the angle:

angle = atan(total y / total x)

Substituting the values from above and evaluating:

angle ≈ -65.1°

Since the angle is negative, we know that the direction is to the west of south. Therefore, the ship is approximately 272.8 miles away from its starting point in a direction that is 65.1° west of south.

There will be 34,31,28,25,22,19 erasers after Day 1,2,3,4,5,6respectively.

Days are units of time that are used to measure the duration of a complete rotation of the Earth on its axis. One day is defined as the time it takes for the Earth to complete one full rotation on its axis, which is approximately 24 hours long.

Starting with 37 erasers, if 3 erasers are lost each day, then the number of erasers in the receptacle for each of the first 6 days can be calculated as follows:

After Day 1: 37 - 3 = 34 erasers

After Day 2: 34 - 3 = 31 erasers

After Day 3: 31 - 3 = 28 erasers

After Day 4: 28 - 3 = 25 erasers

After Day 5: 25 - 3 = 22 erasers

Answer:

Step-by-step explanation:

number of books are 5 so you will have to do 5 by hundred  which will lead to twenty percent

The likelihood that the manager will choose the longest just-received nonfiction book and the shortest recently arrived fiction book is 1/20, or 5%.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

The probability of selecting the shortest fiction book is 1/5 and the probability of selecting the longest nonfiction book is 1/4. Since these events are independent, we can multiply their probabilities to find the probability of both events happening:

P(shortest fiction book and longest nonfiction book) = P(shortest fiction book) x P(longest nonfiction book) = 1/5 x 1/4 = 1/20

So the probability that the manager will select the shortest of the newly arrived fiction books and the longest of the newly arrived nonfiction books is 1/20, which is equivalent to 5%.

As the calculations show, account B will yield a bigger total sum after two  interest  years than account A. As a result, we should deposit our funds in account B.

In mathematics, interest is the amount of money earned or payable on an original investment or loan. You can use either simple or compound interest. Simple interest is calculated as a percentage of the initial amount, whereas compound interest is calculated on the principal amount plus any previously earned interest. If you invest $100 at a 5% annual simple interest rate, you will get $5 in interest every year for three years, for a total of $15.

Account A: Semi-annual interest rate = 10% divided by two equals 5%.

2 years multiplied by 2 equals 4 compounding periods.

Total interest earned Equals Rs. 30,000 multiplied by (1 + 5%/2).

4 - Rs. 30,000 = Rs. 6,380.

13 After two years, the total sum is Rs. 30,000 plus Rs. 6,380.

13 = Rs. 36,380.

Triangles BIG and MOP are similar so, the values of v, w, x, y are 36 cm, 156°, 46.7°, 43.2° respectively.

A triangle is a two-dimensional geometric shape that is formed by three line segments that connect three non-collinear points in a plane. These points are called the vertices of the triangle, and the line segments connecting them are called sides.

Triangles are characterized by several properties, including their side lengths, angles, and areas. Based on the lengths of their sides, triangles can be classified into three types:

Scalene triangle: A triangle in which all three sides have different lengths.

Isosceles triangle: A triangle in which two sides have the same length.

Equilateral triangle: A triangle in which all three sides have the same length.

Since triangles BIG and MOP are similar, we know that their corresponding angles are equal and their corresponding sides are proportional.

Let's first find the value of w in triangle BIG. We know that the sum of angles in a triangle is 180 degrees. Therefore, we can find angle BIG as follows:

angle BIG = 180 - angle BGI

= 180 - 24

= 156 degrees

Now we can use the fact that the corresponding sides of similar triangles are proportional to set up the following ratios:

v/42 = 48/v (since BI/IG = GB/BI)

v^2 = 4248

v = sqrt(4248)

v = 36

In triangle MOP, we can use the law of cosines to find the value of angle MOP:

cos(MOP) = (60^2 + 72^2 - y^2) / (26072)

cos(MOP) = (3600 + 5184 - y^2) / 8640

cos(MOP) = (8784 - y^2) / 8640

MOP = acos((8784 - y^2) / 8640)

MOP = 46.7 degrees (approximately)

Now we can use the fact that the corresponding sides of similar triangles are proportional to set up the following ratios:

v/60 = y/72 (since BI/MO = IG/MP)

y = (v/60)*72

y = (36/60)*72

y = 43.2 cm

Lastly, we can use the fact that the sum of angles in a triangle is 180 degrees to find the value of angle POM in triangle MOP:

angle POM = 180 - angle MOP - 126

= 180 - 46.7 - 126

= 7.3 degrees (approximately)

Therefore, we have:

v = 36 cm

w = 156 degrees

x = 46.7 degrees (approximately)

The cosine of an angle in a right triangle is defined as the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse.

[tex]tanL = 15/8[/tex][tex]sinL = 15/17[/tex][tex]cosL = 8/17[/tex]

In a right triangle, the side opposite the right angle is called the hypotenuse (in this case, it's the side with length 17).

The other two sides are called the legs. We can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:

hypotenuse^2 [tex]= leg1^2 + leg2^2[/tex]

For this triangle, we have:

[tex]17^2 = 8^2 + 15^2[/tex]

Simplifying this equation, we get:

[tex]289 = 64 + 225[/tex]

Therefore, the equation is true, and we have verified that this is a right triangle.

Now, we can use the trigonometric ratios to find the values of tanL, sinL, and cosL, where L is the angle opposite the leg with length 8.

The tangent of an angle in a right triangle is defined as the ratio of the length of the leg opposite the angle to the length of the leg adjacent to the angle. Therefore, we have:

tanL = opposite/adjacent [tex]= 15/8[/tex]

The sine of an angle in a right triangle is defined as the ratio of the length of the leg opposite the angle to the length of the hypotenuse. Therefore, we have:

sinL = opposite/hypotenuse [tex]= 15/17[/tex]

The cosine of an angle in a right triangle is defined as the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse. Therefore, we have:

cosL = adjacent/hypotenuse = 8/17

Using the LIFO perpetual inventory method, the cost of the 18 units sold is $420.

The perpetual inventory strategy known as LIFO (Last In, First Out) is predicated on the idea that the most recent inventory purchases are sold first.

In order to account for the number of units sold, we use this method to count backward from the most recent inventory acquisition.

The business sold 18 units on November 8, which is more than its most recent purchase of 6 units on November 6. Therefore, starting with a total of 18 units, we first use the 10 units from the November 2 purchase and the 8 units from the November 6 buy.

10 units were bought on November 2 for a total of $220, or $22 each unit. The 8 pieces that were bought on November 6 cost $25 apiece, for a total of $200. Hence, $220 plus $200 equals $420 for the 18 units that were sold.

= 6⁷(6 - 6²)

= 6⁷(6 - 36)

= 6⁷(-30)

=(38⁹ - 38⁸)

= 38⁸(38 - 1)

= 38⁸(37)

=(36⁴−6⁹)(38⁹−38⁸)

=6⁷(-30) × 38⁸(37)

=(30)(37)(-6⁷)(38⁸)

Clearly, 30 and 37 are factors, so divisible by them.

The complete question is-

Prove that the value of the expression: b (36^5−6^9)(38^9−38^8) is divisible by 30 and 37.

Probability that a randomly selected August day has a high temperature that exceeds 70°F is approximately 0.7727, or 77.27%.

Assuming that the range of high temperatures in a specific city throughout the month of August is uniform, the probability density function (pdf) of the distribution is as follows:

[tex]f(x) = 1 / (b - a) = 1 / (87 - 65) = 1 / 22[/tex]

where the temperature interval's lower and higher bounds are set at 65 and 87, respectively.

We must determine the area under the pdf curve to the right of x = 70°F in order to determine the likelihood that a randomly chosen August day will have a high temperature that is higher than 70°F. This can be done by integrating the pdf from 70 to 87:

[tex]P(x > 70) = ∫(70 to 87) (70 to 87) f(x) dx = ∫(70 to 87) (70 to 87) 1/22 dx = [1/22 * (x)] (70 to 87) = (1/22) * (87 - 70) = 0.7727[/tex]

As a result, there is a 77.27% probability that an August day chosen at random would have a high temperature above 70 degrees Fahrenheit. This suggests that out of 100 randomly selected August days, we may expect roughly 77 days to have a high temperature surpassing 70°F.

We need to round up to the next higher integer, the sample size required to estimate the mean with an error of +4 and 95 Percent confidence is 170.

To find the sample size to estimate the mean with an error of +4 and 95 percent confidence, we need to use the formula:

n = [(z*sigma)/E]^2

Where:
n = sample size
z = z-score for 95% confidence level (which is 1.96)
sigma = standard deviation (unknown in this case)
E = maximum allowable error (which is +4 in this case)

We are given that o=12, which is the population standard deviation. Since we do not have any information about the sample standard deviation, we can use the population standard deviation as an estimate. Therefore, we can substitute o=12 in the above formula to get:

n = [(1.96*12)/4]^2
n = 169.64

Since we need to round up to the next higher integer, the sample size required to estimate the mean with an error of +4 and 95 percent confidence is 170.

Answer:

X-intercept(s): (-3,0), (-8,0)

Y-intercept(s): (0,48)

Vertex: (-11/2,-25/2)

Step-by-step explanation:

X-intercepts: When you are finding the x-intercepts, there are two ways to find your x-intercepts like you can find in the Quadratic Formula or plug the equation into your calculator and see it on the graph/ table. If you like the quadratic formula, you need plug into the a, b, and c and it will look like x= -22±√(22^2)-4(2)(48))/2(2). It will be the same answer. on the another hand, if you like the calculator way, you get your calculator that need be TI-84 plus CE or TI-84 then go on y= then put your equation like 2x^2+22x+48 after that you click on graph. if you cant find the x-intercepts on the graph, you can do 2nd then above the graph buttom you can see it in the table. When you looking at the table, look for the 0s in the y table.

Y-intercept: When you are finding the y-intercepts, there are two ways to find your y-intercepts like you need plug in 0 for x or plug the equation into your calculator and see it on the graph/ table. If you like the quadratic formula, you need plug in 0 for x and it will look like y=2(0)^2 +22(0)+48. it would the get the same answer. if you like the calculator way, you get your calculator that need be TI-84 plus CE or TI-84 then go on y= then put your equation like 2x^2+22x+48 after that you click on graph. if you cant find the x-intercepts on the graph, you can do 2nd then above the graph buttom you can see it in the table. When you looking at the table, look for the 0s in the x table.

Vertex:

1. Get your equation in the form like this y=ax^2+bx+c

2. Calculate -b/2a. This is the x-coordinate of the vertex.

3. To find the y- coordinate of the vertex, simply plug the x to the quadratic equation and solve for y.
