A man walks due west for 4km. he then changes direction and walks on a bearing of 197° until he is southwest of his starting point.How far is he then from his starting point?
To find the distance between the man's starting point and his final position, we can use vector addition.
Let's call the man's starting point A and his final position B. We can represent the two legs of his journey as vectors A and B, respectively.
The first leg of his journey, due west, can be represented as a vector of magnitude 4 km in the -x direction.
The second leg of his journey, on a bearing of 197°, can be represented as a vector in the -x and -y direction. We can use trigonometry to find the components of this vector.
The x component of the vector can be found using the formula:
x = magnitude * cos(angle) = d * cos(197°)
The y component of the vector can be found using the formula:
y = magnitude * sin(angle) = d * sin(197°)
where d is the magnitude of the vector (the distance the man traveled in this leg of his journey).
To find the magnitude of the vector, we'll use the Pythagorean theorem:
d^2 = x^2 + y^2
We can substitute the x and y components we found above into this equation to find d:
d^2 = (d * cos(197°))^2 + (d * sin(197°))^2
d^2 = d^2 * (cos^2(197°) + sin^2(197°))
d^2 = d^2
d = sqrt(d^2) = sqrt(d^2)
So the magnitude of the vector is d.
Next, we can add the two vectors to find the total distance from the man's starting point to his final position:
distance = sqrt((4 - d * cos(197°))^2 + (d * sin(197°))^2)
This is the distance the man is from his starting point. To find the exact value, we would need to know the value of d. However, without that information, this is as far as we can take the calculation.

Find the x- and y-components of the vector d⃗ = (3. 0 km , 30 ∘ left of +y-axis). Express your answer using two significant figures. Enter the x and y components of the vector separated by a comma
For the information provided the x- and y-components of the vector are 1.5 km and 2.6 km, respectively.
To find the x- and y-components of the vector, we can use trigonometry.
The x-component of vector is given by:
d_x = d × cos(θ)
where d is the magnitude of the vector and θ is the angle between the vector and the x-axis.
In this case, d = 3.0 km and θ = 60 degrees (since the vector is 30 degrees to the left of the y-axis).
So, d_x = 3.0 km × cos(60°) = 1.5 km.
The y-component of vector is given by:
d_y = d × sin(θ)
In this case, d_y = 3.0 km × sin(60°) = 2.6 km.
Expressing the answer using two significant figures gives:
d_x = 1.5 km, d_y = 2.6 km.

What is LCM?In mathematics, the value that is equally divided by the two supplied numbers is known as the LCM of any two. Least Common Multiple is its full name. Another name for it is the Least Common Divisor (LCD).
When the fractions' denominators differ, LCM can also be used to add or subtract any two fractions. LCM is used to make the denominators common when doing any arithmetic operations using fractions, such as addition and subtraction. The simplifying process is facilitated by this procedure.
The system of equation is given as:
−x + 3y = 9
y = 2/3x
The second equation can be written as:
x = 3/2y
Substituting the value of x in equation 1:
-3/2y + 3y = 9
Take the LCM:
-3y + 6y / 2 = 9
-3y + 6y = 18
3y = 18
y = 6
Hence, the y-coordinate for the solution to the system of equations is 6.

What is the relative minimum of the function?
Enter your answer in the box.
A coordinate plane with x axis increments of one increasing from negative 5 to 5 and y axis increments of one increasing from negative 5 to 5. The coordinate plane contains a parabola opening up with a vertex at begin ordered pair one comma negative five end ordered pair. The parabola crosses the y axis at begin ordered pair 0 comma negative 3 end ordered pair.
The relative minimum's coordinates are (1, -5).
How can you determine a function's relative minimum?The first derivative test can be used to determine if a continuous function's critical point is a relative minimum or maximum. Simply put, the first derivative is a relative minimum if it is negative to the left of the critical point and positive to the right of it.
The parabola's equation takes the following form because its vertex is at (1, -5).
y = a(x - 1)² - 5
where "a" is a constant that determines the shape of the parabola. Since the parabola crosses the y-axis at (0, -3), we can substitute these coordinates into the equation and solve for "a" as follows:
-3 = a(0 - 1)² - 5
-3 = a - 5
a = 2
Thus, the equation of the parabola is:
y = 2(x - 1)² - 5
The x-coordinate of the vertex is given by x = 1
find the corresponding y-coordinate by substituting x = 1 into the equation:
y = 2(1 - 1)²- 5 = -5

Step-by-step explanation:
The trick here is to get all the roots to have the same radical. Each of the lowest radical is the square root pf a prime so cannot be reduced further
For example, in a, the lowest is [tex]\sqrt{3}[/tex]
So get all the others to this level a[tex]\sqrt{3}[/tex] and then you can just add up the non-radicals and use the radical as the common expression
I will solve a couple and that will give you a general idea of solving the rest
Let's do a.
[tex]5\sqrt{3} , \sqrt{3}[/tex] are already at the lowest radical level of [tex]\sqrt{3}[/tex] so let's reduce 108 to have [tex]\sqrt{108}[/tex] to have [tex]\sqrt{3}[/tex] as one of its components
We can factor 108 as follows;
108/3 = 36
So 108 = 36 x 3
√108 = √36 × √3 = 6√3
Therefore the original expression becomes
[tex]5\sqrt{3} - 6\sqrt{3} + \sqrt{3} = (5 - 6 + 1)\sqrt{3} = 0 \sqrt{3} = 0[/tex]
[tex]-------------------------------[/tex]
c.
[tex]2\sqrt{20} - 7\sqrt{5} + \sqrt{45}[/tex]
Lowest radical is [tex]\sqrt{5}[/tex] whose coefficient is 7
Factor 20 = 4 x 5
[tex]2\sqrt{20} = 2\sqrt{4 \times 5} = 2\sqrt{4} \times \sqrt{5} = 2\times 2 \times \sqrt{5}\\= \bold{4\sqrt{5}}[/tex]
Factor 45:
45 = 9 x 5
[tex]\sqrt{45} = \sqrt{9} \times \sqrt{5} = \bold{3\sqrt{5}}[/tex]
Original expression becomes:
[tex]4\sqrt{5} - 7\sqrt{5} + 3\sqrt{5}\\\\=(4 - 7 + 3)\sqrt{5}\\\\= 0 \sqrt{5}\\\\= 0\\----------------------------[/tex]

The statement "the sum of a two-digit number is less than the value of the original two-digit number" can be rewritten as conditional statement. If the sum of two digits of a two-digit number is less than the value of the original two-digit number, the number is valid.
A conditional statement, "if p, then q," with p representing the hypothesis and q representing the conclusion. We can identify the hypothesis and conclusion by rewriting the statement "the sum of the digits of a two-digit number is less than the value of the original two-digit number" as an if-then conditional statement.
The hypothesis is the condition that must be satisfied in order to valid the conclusion. In this case, the hypothesis is "the sum of the digits of a two-digit number is less than the value of the original two-digit number".
By combining these, we can rewrite the statement as follows:
If the sum of a two-digit number's digits is less than the value of the original two-digit number, the number is valid.
The hypothesis (the sum of the digits of a two-digit number is less than the value of the original two-digit number) is a sufficient condition for the conclusion, according to this conditional statement (the number is valid). In other words, if the hypothesis is correct, we can be certain that the conclusion is correct as well.

As a result, Glacier produces 8 million pairs of shorts and 48 million pounds of almonds, and Sequoia produces 15 million pairs of shorts and 20 million pounds of almonds. Assume there are no other countries willing to engage in trade, so, in the absence of trade between these two countries, each country consumes the amount of shorts and almonds it produces.
In the absence of trade between Glacier and Sequoia, Glacier would consume 8 million pairs of shorts and 48 million pounds of almonds, and Sequoia would consume 15 million pairs of shorts and 20 million pounds of almonds. However, if both countries decide to engage in trade, Glacier could specialize in producing shorts, using 1 million hours of labor per week, and Sequoia could specialize in producing almonds, using 1 million hours of labor per week. This specialization would result in Glacier producing 12 million pairs of shorts and Sequoia producing 24 million pounds of almonds. This would enable each country to consume more of both goods than they could produce in the absence of trade.
35% off of a 85 dollar item
The amount after 35% off on a 85 dollar item will be $55.25
What is the percentage?Percentage is a way to express a number as a fraction of hundred. It is often used to represent proportions and ratios in a more convenient and understandable form, especially in financial statistical and financial contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
To find the sale price of an item that has a discount, you can use the following formula:
Sale price = Original price - (Discount percent × Original price)
In this case, the discount is 35% off of an $85 item. So we have:
Discount percent = 35%
Original price = $85
Substituting these values into the formula, we get:
Sale price = $85 - (35% × $85)
Sale price = $85 - $29.75
Sale price = $55.25
Therefore, the sale price of the item after a 35% discount is $55.25.

4) Tyler is sitting at a corner of an 80 ft. by 40 ft. pool. Stretched diagonally across the pool
opposite Tyler is his friend Jason. How far must Tyler swim to reach Jason?
Answer:
Step-by-step explanation:
To find the distance Tyler needs to swim, we can use the Pythagorean theorem. The theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side, which is the hypotenuse.
In this case, the two shorter sides of the triangle are 40 feet and 80 feet, and the hypotenuse is the distance Tyler needs to swim to reach Jason. So we can write the equation as follows:
40^2 + 80^2 = d^2
where d is the distance Tyler needs to swim.
Expanding the equation:
1600 + 6400 = d^2
8000 = d^2
Taking the square root of both sides:
d = sqrt(8000) = 80 * sqrt(2)
So, Tyler needs to swim a distance of 80 * sqrt(2) feet, or approximately 113.1 feet, to reach Jason.
five times the sum of a number and two is nineteen less than six times the number.
Answer:
The number is 29.
Step-by-step explanation:
"five times the sum of a number and two" can be represented as 5(x + 2), where x is the number. "nineteen less than six times the number" is the same as 6x - 19. The word "is" determines that these two parts are equal. So, 5(x + 2) = 6x - 19.
Solve:
5x + 10 = 6x - 19
10 = x - 19
x = 29
Check:
5 * (29 + 2) = 5 * 31 = 155
(6 * 29) - 19 = 155
155 = 155
Which equation represents a nonlinear function?
Answer:
A nonlinear function is a function in which the rate of change of the output (y) is not proportional to the rate of change of the input (x). In other words, a nonlinear function is a function where the graph of the function is not a straight line.
Here are a few examples of equations that represent nonlinear functions:
y = x^2: This is the equation for a parabolic function, which is a classic example of a nonlinear function.
y = sin(x): This is the equation for the sine function, which is periodic and nonlinear.
y = |x|: This is the equation for the absolute value function, which is nonlinear and has a "kink" at x = 0.
y = log(x): This is the equation for the natural logarithmic function, which is also nonlinear.
These are just a few examples of nonlinear functions. There are many other types of nonlinear functions, including polynomial, exponential, and trigonometric functions.
