Answer:
10
Step-by-step explanation:
We can use the distance formula to find the distance between the two points:
Distance = √((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the coordinates of A and B, we get:
Distance = √((-2 - 6)^2 + (-1 - 5)^2)
Distance = √((-8)^2 + (-6)^2)
Distance = √(64 + 36)
Distance = √100
Distance = 10
Therefore, the distance between A(6, 5) and B(−2, −1) is 10 units.

c. Describe the relationship between the average price of jeans and number of jeans sold.
The ordered pairs from the table are (22, 152), (28, 94), (35, 134), and (46, 110). Plotting them on a coordinate plane would produce a scatterplot.
The form of the scatterplot is a line of negative slope that is decreasing from left to right. The direction of the scatterplot is downward.
The relationship between the average price of jeans and number of jeans sold appears to be negative, which means that as the average price of jeans increases, the number of jeans sold decreases. In other words, there is an inverse relationship between the price and quantity demanded of jeans. This relationship is consistent with the law of demand in economics, which states that as the price of a good or service increases, the quantity demanded of that good or service will decrease, ceteris paribus (all else being equal).

Each end of the lawn is a semi-circle of radius x metres.
The lawn has perimeter 90 m and area S m ²
d. S
dx

Given S = 90x-x², then
The value x = 14. 32 gives a maximum value of S
Find, to the nearest whole number, the maximum value of S
The nearest whole number, the maximum value of S is equivalent to approximately 323 m², which is the area of the lawn.
We are given that the perimeter of the lawn is 90 m. Therefore, we can write:
2y + 4x + 2πx = 90
where π is the constant pi. Simplifying this equation gives:
y = 22.5 - 2x - πx
The area of the lawn is given by:
S = y(2x) + πx²
Substituting y in terms of x gives:
S = (22.5 - 2x - πx)(2x) + πx²
Simplifying this expression gives:
S = 45x - 2πx² - 4x²
We are asked to find the maximum value of S. To do this, we can differentiate S with respect to x and set the derivative equal to zero:
dS/dx
= 45 - 4πx - 8x = 0
Solving for x gives:
x = (45 - 4π)/8
Substituting this value of x into the expression for S gives:
S ≈ 323 m²
Rounding this value to the nearest whole number gives:
S ≈ 323 m².
Therefore, the maximum value of S is approximately 323 m².

Based on this record, what is the probability of picking up a medal won by him in the years 2009 or 2012
The probability of picking a medal won by Sam in the years 2009 or 2012 is 5/6.
The probability of picking a medal won by Sam in the years 2009 or 2012 can be calculated using the formula P(A∪B) = P(A) + P(B) - P(A∩B). In this case, P(A) equals the probability of picking a medal won by Sam in 2009, which is 1/3, and P(B) equals the probability of picking a medal won by Sam in 2012, which is 1/2. P(A∩B) would be the probability of picking a medal won by Sam in both years, which is 0, since he did not win a medal in both years. Therefore, the probability of picking a medal won by Sam in the years 2009 or 2012 is P(A∪B) = P(A) + P(B) - P(A∩B) = 1/3 + 1/2 - 0 = 5/6.

Write a quadratic function that has vertex in the third quadrant
and has no x-intercept, Explain how your find such function.
Quadratic function that has vertex in the third quadrant and has no x-intercept is f(x) = 2(x+3)² - 4.
Quadratic function is a polynomial function of the second degree of the form f(x)= ax² + bx + c where a is a non-zero coefficient and x is the variable. Vertex is the point on the parabola which has a minimum or maximum point. The third quadrant is where both the x and y coordinates are negative. The question requires finding a quadratic function with vertex in the third quadrant and has no x-intercept. Quadratic function with no x-intercept means that the graph does not cross the x-axis. Here is how to find such function: Step-by-step We can start by using the vertex form of a quadratic function. f(x) = a(x-h)² + k Where (h, k) is the vertex of the parabola. Since the vertex is in the third quadrant, h and k should be negative numbers.
Also, since the graph should not cross the x-axis, the leading coefficient (a) should be either positive or negative. If a>0, the parabola opens upwards, and if a<0, the parabola opens downwards. To find a quadratic function that has no x-intercept and has a vertex in the third quadrant, let's choose any negative value of h and k such that |k|>|h|, and a>0. For instance, let h=-3 and k=-4. Then, substituting these values in the vertex form, we get:f(x) = a(x+3)² - 4If we want the parabola to have a minimum point at the vertex, then a should be positive. We can choose any positive value of a. For example, let's take a=2. Then, the quadratic function with the required conditions is:f(x) = 2(x+3)² - 4f(x) = 2x² + 12x + 14The graph of this function has vertex (-3, -4) and does not cross the x-axis. Quadratic function that has vertex in the third quadrant and has no x-intercept is f(x) = 2(x+3)² - 4.

the death rate from Covid19 in a certain country is 6%. what is
the probability that at least 2 patients will die out of next 10
patients
P(X≥2) = 1 - 0.389 - 0.409= 0.202. The probability that at least 2 patients will die out of next 10 patients is 0.202.
The death rate from Covid19 in a certain country is 6%. The probability that at least 2 patients will die out of next 10 patients can be found using binomial distribution. What is binomial distribution? Binomial distribution is a probability distribution that deals with the number of successes or failures in a given number of trials. A binomial distribution model is characterized by the following conditions: There are only two outcomes of the trials, either success or failure. The probability of success is constant throughout the trials.
The trials are independent of each other. The formula for the probability of binomial distribution is as follows: P(X=k) = (n C k) × p^k × (1-p)^(n-k)Where P(X=k) is the probability of k successes out of n trials. n C k represents the number of ways of selecting k items out of n items. p is the probability of success.1-p is the probability of failure. Using the above formula, the probability that at least 2 patients will die out of next 10 patients is: P(X≥2) = 1 - P(X=0) - P(X=1)P(X=0) = (10 C 0) × 0.06^0 × (1-0.06)^(10-0)= 0.389P(X=1) = (10 C 1) × 0.06^1 × (1-0.06)^(10-1)= 0.409Therefore,P(X≥2) = 1 - 0.389 - 0.409= 0.202The probability that at least 2 patients will die out of next 10 patients is 0.202.

Sabiendo que sen alpha = 0. 6 y que a es un ángulo agudo, calcula el resto de razones trigonométricas
Translate: Knowing that sen alpha = 0. 6 and that a is an acute angle, calculates the rest of trigonometric ratios
Rest of the trigonometric ratios for the acute angle alpha are cos(alpha) = 0.8 and tan(alpha) = 0.75.
If we know that sin(alpha) = 0.6, we can use the Pythagorean identity to find cos(alpha) and tan(alpha). Here's how:
Since sin(alpha) = opposite/hypotenuse, we can represent sin(alpha) as the ratio of the length of the side opposite the acute angle alpha to the length of the hypotenuse of the right triangle. Let's assume that the length of the opposite side is a and the length of the hypotenuse is h. Then we have:
sin(alpha) = a/h = 0.6
Solving for a, we get:
a = 0.6h
Using the Pythagorean theorem:
[tex]a^2 + b^2 = h^2[/tex]
Since a and h are related by a = 0.6h, put 0.6h for a to get:
[tex](0.6h)^2 + b^2 = h^2[/tex]
Simplifying:
[tex]0.36h^2 + b^2 = h^2[/tex]
[tex]b^2 = h^2 - 0.36h^2 = 0.64h^2[/tex]
[tex]b = \sqrt{0.64h^2} = 0.8h[/tex]
So now we know that b = 0.8h and a = 0.6h. Using these values, we can find cos(alpha) and tan(alpha) as follows:
[tex]cos(alpha) = adjacent/hypotenuse = b/h = 0.8h/h = 0.8tan(alpha) = opposite/adjacent = a/b = 0.6h/0.8h = 0.75[/tex]
Therefore, the rest of the trigonometric ratios for the acute angle alpha are cos(alpha) = 0.8 and tan(alpha) = 0.75.

if (x-2)^2 =2 what values of x make the quadratic equation
The values of x make the quadratic equation (x-2)² =2 is 2 + √2.
To find the values of x that make the quadratic equation (x-2)² = 2 true, we need to solve for x.
First, we can take the square root of both sides of the equation:
x - 2 = ±√2
Next, we can add 2 to both sides of the equation:
x = 2 ± √2
Therefore, the two solutions for x are:
x = 2 + √2
x = 2 - √2
These are the two values of x that make the quadratic equation (x-2)^2 = 2 true.
To check these solutions, we can substitute each value back into the original equation:
[(2 + √2) - 2]² = 2
Simplifying:
√2² = 2
2 = 2
This solution works. Now let's check the other solution:
[(2 - √2) - 2]² = 2
Simplifying:
-√2² = 2
-2 = 2
This solution does not work, so we discard it. Therefore, the only value of x that makes the quadratic equation (x-2)² = 2 true is: x = 2 + √2.

Claude will use 1197 square centimeters of labeling material to cover the lateral surface of 5 cylindrical bug spray cans.
Laminar surface area: what is it?A three-dimensional object's lateral surface area is its total surface area minus its top and bottom surfaces. The lateral surface area of a cylinder, for instance, would be the area of the curved side of the cylinder. In geometry and engineering, the lateral surface area is frequently used to determine how much material is required to cover or build an object's sides. Depending on the geometry of the item, many formulae may be used to compute the lateral surface area, which is often expressed in square units (such as square centimetres or square feet).
Given the dimensions of the cylindrical can we have the lateral surface area of cylinder as:
Lateral surface area = 2πrh
Substituting the value r = 3 and h = 12.7 we have:
Lateral surface area = 2π(3)(12.7) = 239.4 square centimeters
A total of 5 cans need to be covered thus,
Total labeling material = 5 x 239.4 = 1197 square centimeters

Each of the interior angles of a regular polygon is 140 degrees. How many have it
Answer:
The polygon has 9 sides, and it is a nonagon.
Step-by-step explanation:
The formula to find the sum of the interior angles of a regular polygon is:
S = (n - 2) × 180
where S is the sum of the interior angles and n is the number of sides.
If each interior angle of the polygon is 140 degrees, we can use the formula to solve for n:
n = (S / 140) + 2
Plugging in S = 180(n-2) and simplifying, we get:
n = (180(n-2) / 140) + 2
n = (9n - 18) / 7
7n = 9n - 18
-2n = -18
n = 9
Therefore, the polygon has 9 sides, and it is a nonagon.

Based on the information, the only prediction that is justified is that the speed of the fish will be greater than 40 mph, and the speed of the mammal will be less than 50 mph.
Therefore option B is correct.
How do we know this?Based on the given information above, we were able to deduct that about 75% of the fish were faster than 40 mph and about 75% of the mammals were slower than 50 mph.
We can go ahead and use this information to make predictions about the speeds of one additional fish and one additional mammal.
Note that the median speed is around 50 mph, and the upper quartile (75th percentile) is around 60 mph and we know that about 75% of the fish were faster than 40 mph, we can predict that the additional fish will have a speed greater than 40 mph. However, since the upper quartile is only at 60 mph, we cannot predict that the additional fish will have a speed greater than 60 mph. Therefore, the only prediction that is justified is that the speed of the fish will be greater than 40 mph, which eliminates options A and D.the only prediction that is justified is that the speed of the fish will be greater than 40 mph, and the speed of the mammal will be less than 50 mph, which is option BLearn more about speed at:

Step-by-step explanation:
Area of rose garden = 5.5 * 3.75 = 20.625
Area of vegetable garden = 13.75 * 6 = 82.5
To find how many times greater the area of the vegetable garden is, we simply divide 82.5 by 20.825
82.5 / 20.625 = 4
16. A 40-ft. guy wire helps to support a tower. The wire is anchored to the ground 19 ft. from the base of
the tower. What is the measure of the angle formed between the wire and the ground, to the nearest
degree?
a.
25°
b. 65°
C.
62°
d. 28°
laual ground and the trunk is
Answer:
We can use trigonometry to solve this problem. Let θ be the angle formed between the wire and the ground. Then, using the right triangle formed by the wire, the tower, and the ground, we have:
cos θ = adjacent/hypotenuse
where the adjacent side is 19 ft. (distance from the base of the tower to the anchor point) and the hypotenuse is 40 ft. (length of the guy wire). Solving for θ, we get:
θ = cos^-1(19/40) ≈ 62°
Therefore, the measure of the angle formed between the wire and the ground is approximately 62 degrees. Answer C.

A local hamburger shop sold a combined total of 441 hamburgers and cheeseburgers on Tuesday. There were 59 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Tuesday?
Accοrding tο given cοnditiοns, 250 hamburgers were sοld οn Tuesday.
What is algebra ?Algebra is a branch οf mathematics that deals with symbοls and the rules fοr manipulating thοse symbοls. It invοlves sοlving equatiοns and manipulating variables tο find unknοwn values.
Let's use algebra tο sοlve the prοblem.
Let x be the number οf hamburgers sοld.
Then the number οf cheeseburgers sοld is x - 59.
The tοtal number οf hamburgers and cheeseburgers sοld is 441, sο we can write an equatiοn:
x + (x - 59) = 441
Simplifying the left side, we get:
2x - 59 = 441
Adding 59 tο bοth sides, we get:
2x = 500
Dividing by 2, we get:
x = 250
Therefοre, accοrding tο given cοnditiοns, 250 hamburgers were sοld οn Tuesday.

Answer:
The answer to your problem is, Area = 104.1 square feet.
Step-by-step explanation:
Area of semicircle = 1/2 the area of a circle:
[tex]A_{sc} = \frac{1}{2} tt r^{2}[/tex]
Radius is half the diameter of 6ft.
[tex]A_{sc} = \frac{1}{2} tt ( 3^{2} ) = 14.13ft^{2}[/tex]
Area of the rectangle:
[tex]A_{r} = lw = 15 * 6 = 90ft^{2}[/tex]
Add them:
[tex]90 + 14.13 = 104.13[/tex]
Round to the nearest tenth (one decimal place)
Which is 104.1
Thus the answer to your problem is 104.1 of 104.13
What is the distance in units between the points (1, 0) and (8, 0)?
In response to the stated question, we can state that As a result, there coordinates are 7 units between the points (1, 0) and (8, 0).
what are coordinates?When locating points or other geometrical objects precisely on a manifold, such as Euclidean space, a coordinate system is a technique that uses one or more integers or coordinates. Locating a point or item on a two-dimensional plane requires the use of coordinates, which are pairs of integers. Two numbers called the x and y coordinates are used to describe a point's location on a 2D plane. a collection of integers that indicate exact locations. The figure often has two numbers. The first number denotes the front-to-back measurement, while the second number denotes the top-to-bottom measurement. For example, in (12.5), there are 12 units below and 5 above.
The distance formula can be used to determine the separation between two points in a two-dimensional Cartesian coordinate system:
[tex]\sqrt[(x2 - x1)2 + (y2 - y1)2] = d[/tex]
and d .
As both of the points in this instance have y-coordinates of 0, we may condense the expression to:
[tex]d = \sqrt[(8 - 1)^² + (0 - 0)^²]\\d = \sqrt[(7)^² + (0)^²]\\d = \sqrt[49]\\ d= 7[/tex]
As a result, there are 7 units between the points (1, 0) and (8, 0).
