A ship is sailing east. at one point, the bearing of a submerged rock is 44 degrees 20 prime44°20′. after the ship has sailed 15.715.7 mi, the bearing of the rock has become 308 degrees 40 prime308°40′. find the distance of the ship from the rock at the latter point.

Answers

Answer 1

Let A be the position of the ship at which the rock is found at B, after travelling 15.7 miles the ship reaches point C, thus ABC forms a triangle that has the dimensions of
AC=15.7
and
∠x=BAC=90-44°20'=45°40'
∠y=∠BCA=360-270=90
∠ABC=180-∠x-∠y=44°20'
therefore using sine law
BC/sin (44°40')=15.7/sin (45°20')
⇒BC=15.5184 miles

What is the value of k used to find the coordinates of a point that partitions a segment into a ratio of 5:3?

Answers

Since the value of k can be determined by dividing the numerator of the original ratio, which is 5, by the sum of the numerator and denominator of the ratio:
(5+3)=8

Thus the value for k = 5/8

Answer:

[tex]\frac{5}{8}[/tex]

Step-by-step explanation:

We are asked to find the value of k used to determine the coordinates of a point that partitions a segment into a ratio of 5:3.

The value of k would be 5 divided by the sum of 5 and 3.

[tex]k=\frac{5}{3+5}[/tex]

[tex]k=\frac{5}{8}[/tex]

Therefore, the value of k is [tex]\frac{5}{8}[/tex].

Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make a 12% detergent solution. Which equation can she use to find g, the number of gallons of water she should add?

Answers

A suitable equation will equate the quantity of detergent both before and after the water is added to the solution.

the amount of detergent in 11 gal of 18% solution is the same as the amount of detergent in the 12% solution (after g gallons of water are added)
.18*11 = .12*(11+g)

Answer:

[tex]\frac{1.98}{11+g}=\frac{12}{100}[/tex]

Step-by-step explanation:

Given,

Total quantity of solution = 11 gallons

Initial detergent in the solution = 18 % of 11 gallons

[tex]=\frac{18\times 11}{100}[/tex]

[tex]=\frac{198}{100}[/tex]

[tex]=1.98\text{ gallons}[/tex]

Now, here g represents the number of gallons of water she should add to make 12 % detergent solution,

Final quantity of solution = ( 11 + g ) gallons

Thus, we can write,

The part of detergent in (11+g) gallons of water = The final percentage of detergent

[tex]\frac{1.98}{11+g}=\frac{12}{100}[/tex]

For this case we can write the system of equations as two equations with two unknowns.
We then define the following unknowns:

We write the system of equations:
y = x2 + 3x + 1
y = 2x2 + 2x + 3
Answer:
y = x2 + 3x + 1
y = 2x2 + 2x + 3

Final answer:

The given equation can be converted into a system of equations by setting each side of the given equation to equal zero separately. The system of equations will then be x² - x + 2 = 0 and x² + 3x + 1 = 0.

Explanation:

The given equation, x²+3x+1=2x²+2x+3, can be set as a system of equations by getting each side of the equation to equal zero. Begin by subtracting the entire left-hand side of the equation from the right-hand side which gives us:

2x² + 2x + 3 - (x² + 3x + 1) = 0

This simplifies to x² - x + 2 = 0. That's your first equation.

Now, take the left-hand side of the original equation and set it equal to zero: x² + 3x + 1 = 0. That's your second equation. So the system of equations from the original equation are:

x² - x + 2 = 0 x² + 3x + 1 = 0

Assume that X has a normal distribution, and find the indicated probability. The mean is μ= 15.2 and the standard deviation is σ = 0.9. Find the probability that X is greater than 16.1.

Answers

Answer:0.1587

Step-by-step explanation:

z = (x-μ)/σ

mean, μ= 15.2

standard deviation, σ = 0.9

To find the probability that x is greater than 16.1,

x = 16.1

z = (16.1-15.2)/0.9

= 1

Looking at the normal distribution table, the area covered by 0 to 1

=0.8413

Therefore, the probability that x is greater than 16.1, = 11- probability that x = 16.1

= 1-0.8413

The price of an item has risen to $276 today. Yesterday it was $115. Find the percentage increase.

Answers

are you kidding me, bro? lol

276-115=131
131 divided by 276 = 0.47

0.47% increase

Final answer:

The student's question asked for finding the percentage increase in an item's price. This can be calculated by subtracting the initial price from the final price, dividing that difference by the initial price, and then multiplying the result by 100. In this case, the price of the item has increased by 140% from yesterday to today.

Explanation:

To find the percentage increase of the price of an item, we subtract the initial price from the final price, then divide that number by the initial price, finally multiply that result by 100 to obtain the percentage. In this case, the initial price of the item was $115, and the final price is $276.

Here's how the calculation works:

Subtract the initial price from the final price: $276 - $115 = $161. Divide the difference by the initial price: $161 / $115 ≈ 1.4. Multiply the result by 100 to get the percentage increase: 1.4 * 100 = 140%.

Therefore, the price of the item has increased by 140% from yesterday to today.

Determine the number of x-intercepts that appear on a graph of each function. f (x) = (x + 2)(x - 1)[x - (4 + 3i )][x - (4 - 3i)]

Answers

f(x) has two real roots, -2 and +1. Those are the only x-intercepts.

f(x) has 2 x-intercepts.

Answer:

This function has two x-intercepts.

Step-by-step explanation:

The number of x-intercepts of a function is given by the number of REAL ROOTS of the function. A complex root does not intercept x.

In this function, we have

Two real roots: x = -2 and a x = 1

Two complex roots: x = -4 + 3i and x = -4 - 3i

So this function has two x-intercepts.

A neighbor needs to put up a square fence around her garden to keep the deer out. If the area is 500 square feet, how much fence does she need to buy, rounded to the nearest tenth of a foot? Show your work.

Answers

Area of a square = length * width

And since it’s a square the length and width is the same amount

So width=length=L
500 ft^2=L*L=L^2

Square root both sides
Sqrt(500 ft^2) =L= 22.36067977

The neighbor needs to buy approximately 89.6 feet of fencing to surround her 500 square feet garden, which is a square. This is calculated by taking the square root of the area to find the length of one side and then multiplying by four to get the perimeter.

To determine how much fence the neighbor needs to buy to surround her square garden, we need to calculate the perimeter of the square. The area of a square is given by the formula Area = side × side or Area = side². Since the area is 500 square feet, we first find the length of one side of the square by taking the square root of the area:

Side = √Area = √500 ft²

The square root of 500 is approximately 22.4 feet. Now, we calculate the perimeter, which is the sum of all four sides of the square:

Perimeter = 4 × side = 4 × 22.4 ft = 89.6 ft

Rounded to the nearest tenth of a foot, the neighbor needs to buy approximately 89.6 feet of fencing to surround her garden.

Find the greatest common divisor of 100 and 254, using • prime factorization- • euclidean algorithm-

Answers

Via prime factorization:

[tex]254=2\cdot127[/tex]

of which the only common factor is a single power of 2, so [tex]\mathrm{gcd}(100,254)=2[/tex].

Via the Euclidean algorithm:

[tex]254=2\cdot100+54[/tex]
[tex]100=1\cdot54+46[/tex]
[tex]54=1\cdot46+8[/tex]

which means [tex]\mathrm{gcd}(100,254)=2[/tex], as expected.

Final answer:

The Greatest Common Divisor (GCD) of 100 and 254 can be found using Prime Factorization and the Euclidean Algorithm. Both methods produce a GCD of 2.

Explanation:

The student is asking for how to find the Greatest Common Divisor (GCD) of 100 and 254 using two different methods: Prime Factorization and the Euclidean Algorithm.

Prime Factorization: Start by writing down each number's prime factors. The prime factors for 100 are 2, 2, 5, 5 and the prime factors for 254 are 2, 127. The GCD is the product of the smallest power of each common prime number. In this case, the only common prime number is 2, so the GCD by prime factorization is 2.Euclidean Algorithm: This method begins with the larger number (254) and divides it by the smaller one (100). Write down the remainder (54). Then, divide the smaller number (100) by the remainder from the last step (54) to get a new remainder (46). The process is repeated until there is no remainder. The last non-zero remainder serves as the GCD. In this case, the process would continue as follows: 54 divided by 46 equals 1 remainder 8, then 46 divided by 8 equals 5 remainder 6, then 8 divided by 6 equals 1 remainder 2, then 6 divided by 2 equals 3, no remainder. Therefore, the GCD by Euclidean Algorithm is also 2.
