What will be the new position of the given point (-6,8) after rotating 90° clockwise about the origin
Answer:( 8, 6)
Step-by-step explanation:
After rotating the point (-6,8) 90° clockwise about the origin, the new position of the point will be (8,6).
Explanation:When a point is rotated 90° clockwise about the origin in a two-dimensional Cartesian coordinate system, the new position of the point can be calculated by changing the sign on the y-coordinate and swapping the order of the x and y-coordinates. For your specific question, we are given the point (-6,8). So, the new position of the point after the rotation would be (8,6). This is because rotations in a clockwise direction can be considered as negative in mathematics, and portions rotate around the origin following the right-hand rule.

5. A polygon has a perimeter of 18 units. It is dilated with a scale factor of What is the
perimeter of its image?
a.
12 units
b.
24 units
C.
27 units
d.
30 units
The question appeared to ask about the impact of dilation on a polygon's perimeter, but the scale factor was not provided. Generally, the perimeter of a dilated polygon is the original perimeter multiplied by the scale factor. Another part of the student's question involved calculating the actual diameter of a swimming pool from a scale drawing using a provided scale factor.
Explanation:The student appears to have asked a question about a dilation of a polygon and its effect on the perimeter, as well as having other queries related to scale factors and how they apply to various geometric figures and real-life objects. Unfortunately, the specific scale factor for the dilation in question 5 is not provided. However, generally speaking, when a figure is dilated by a scale factor, the length of all sides is multiplied by that factor. Given that the perimeter is the sum of all side lengths, the perimeter of the dilated polygon would also be multiplied by the same scale factor. So if a polygon has a perimeter of 18 units and it is dilated by a scale factor, to find the perimeter of the dilated image we multiply the original perimeter by the scale factor. It's important to note that without knowing the exact scale factor, we cannot determine what the new perimeter would be.
For question 12, to find the actual diameter of the pool, we need to use the scale factor provided, which is 1/72. If the scale drawing shows a diameter of 1(1/2) inches, we can calculate the actual diameter using the following:
Convert 1(1/2) inches to feet by multiplying by the scale factor. Since 1 inch equals 1/72 feet in the scale, 1(1/2) inches equals 1(1/2) * 1/72 feet.Then, to find the actual diameter, we multiply 1(1/2) by 72.The rest of the calculations follow a similar method, using the respective scale factors and measurements to determine the actual sizes or scale sizes of objects.

The correct option is d. [tex]30\ units[/tex]. This means that the original polygon was dilated with a scale factor of to obtain the image with a perimeter of [tex]30\ units.[/tex]
To find the perimeter of the image of a polygon after dilation with a scale factor, we need to understand how dilation affects the dimensions.
1. Perimeter of the original polygon:
Let's denote the original perimeter of the polygon as [tex]\( P \)[/tex]. According to the problem, the original perimeter is [tex]18 \ units[/tex]
[tex]\( P = 18 \) \ units[/tex]
2. Dilation with a scale factor:
Dilation with a scale factor [tex]\( k \)[/tex] multiplies all dimensions (lengths of sides) of the polygon by [tex]\( k \).[/tex]
3. Perimeter after dilation:
After dilation with a scale factor [tex]\( k \)[/tex], the perimeter [tex]\( P' \)[/tex] of the polygon's image is given by:
[tex]\( P' = k \times P \)[/tex]
Here, [tex]\( k \)[/tex] is the scale factor.
4. Calculating the perimeter of the image:
The problem states that the polygon is dilated with a scale factor of [tex]\( \sqrt{3} \)[/tex]. So, [tex]\( k = \sqrt{3} \).[/tex]
Now, calculate [tex]\( P' \)[/tex]
[tex]\( P' = \sqrt{3} \times 18 \)[/tex]
[tex]\( P' = 18 \times \sqrt{3} \)[/tex]
[tex]\( P' = 18 \times 1.732 \)[/tex]
[tex]\( P' = 31.176 \)[/tex]
None of the given options match the exact calculated perimeter [tex]\( P' = 31 \) units[/tex]. However, based on the options provided, the closest answer to our calculated value is [tex]30\ units[/tex] (option d).
The probability that a softball player named Casey gets a base hot during a single time at bat is 4/10. If he goes to bat 4 times in his next game (which is played in Mudville), determine:
A)The probability that he gets 4 hits.
B) the probability that he gets no hits, causing no joy in Mudville.
C) the probability that he gets 3 or more hits.
Final answer:
To determine the probabilities of Casey's performance in a softball game, we compute the outcomes of him getting 4 hits (0.0256), getting no hits (0.1296), and getting 3 or more hits (0.2048) using the rules of probability for independent events.
Explanation:
The probability of the softball player Casey getting a hit is 4/10. To solve the various probabilities related to Casey's performance:
A) The probability that he gets 4 hits in 4 at-bats can be calculated by raising the probability of getting a hit to the fourth power since each at-bat is an independent event. This gives us (4/10) 4 or 0.0256.B) The probability that he gets no hits in 4 at-bats is the probability of not getting a hit (which is 1 - 4/10 = 6/10) raised to the fourth power, resulting in (6/10) 4 or 0.1296.C) The probability that he gets 3 or more hits is the sum of the probabilities of getting exactly 3 hits and getting 4 hits. To get exactly 3 hits, we can calculate 4 choose 3 (which is 4) times the probability of getting a hit three times and not getting a hit once, giving us 4 * (4/10) 3 * (6/10). Adding the probability of getting 4 hits, we get 0.1792 + 0.0256 = 0.2048.Solve for X

The height of the cone is 4 inches.
Step-by-step explanation:
Step 1:
The given triangle is a right-angled triangle.
The length of the hypotenuse is 5 inches. One of the other sides is 3 inches long. Assume the other side of the triangle measures x inches.
According to Pythagoras' theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Step 2:
(The length of the hypotenuse)² = (The other sides length)² + (The other sides length)²
By substituting the values in the equation, we get
[tex]5^{2} = 3^{2} + x^{2} , x^{2} = 25 - 9 = 16.[/tex]

Find the area of the rectangle that has the vertices (-2, 0). (0-4). (2.0), and (0,4), respectively.
Final answer:
Area of the rectangle that has the vertices (-2, 0). (0-4). (2.0), and (0,4) is 32 square units.
Explanation:
To find the area of a rectangle, we need to use the formula:
Area = length x width
In this case, the vertices of the rectangle are (-2, 0), (0, -4), (2, 0), and (0, 4). We can calculate the length and width by finding the difference in the x-coordinates and y-coordinates, respectively.
The length is 2 - (-2) = 4 and the width is 4 - (-4) = 8.
Therefore, the area of the rectangle is:
Area = 4 x 8 = 32 square units.
In ΔXYZ, the measure of ∠Z=90°, YX = 97, XZ = 65, and ZY = 72. What ratio represents the tangent of ∠Y?
Final answer:
The tangent of ∠Y in ΔXYZ is the ratio of the length of side XZ to the length of side ZY, which is 65/72.
Explanation:
In ΔXYZ, we are given that ∠Z = 90°, YX = 97, XZ = 65, and ZY = 72. To find the tangent of ∠Y, we use the definition of the tangent function in a right triangle, which is the ratio of the length of the opposite side to the length of the adjacent side for the given angle.
Since ∠Z is the right angle and we are interested in a tangent of ∠Y, the opposite side to ∠Y is XZ (which measures 65), and the adjacent side to ∠Y is ZY (which measures 72).
Therefore, the tangent of ∠Y is given by the ratio:
tan(∠Y) = opposite/adjacent = XZ/ZY = 65/72.

The manager of a grocery store estimates that 74% of customers will make a purchase.
Part A: How many customers should a cashier expect until he finds a customer that makes a purchase?
Part B: What is the probability that a cashier helps 3 customers until he finds the first person to make a purchase?
Answer:
A : Per 100 people, cashier should expect 26 customer until he finds a costumer that makes a purchase.
B: The probability is 1/4
Step-by-step explanation:
The estimated chance of a customer making a purchase = 74%
So, if a TOTAL of 100 people visit the grocery store on any random day,
then 74 % of customers
= 74% of 100
= 74 people will make purchases.
⇒ Out of total 100 people visiting, 74 people will make a purchase.
So, the number of people NOT making a purchase = 100 - 74 = 26
⇒ Out of total 100 people visiting, 26 people will NOT make a purchase.
Also, 26 = 26% of 100
Part A :
So, in order to make a purchase, cashier should expect 26% of customers because the percentage of NOT purchasing is 26%.
Hence, per 100 people, cashier should expect 26 customer until he finds a costumer that makes a purchase.
Part B :
The percentage of customer making a purchase = 74%
The percentage of people NOT making a purchase = 26%
So, for every 3 customer making a purchase there is a 1 person NOT making a purchase.
So, the probability is 1/4
Part A)
1.35 customers until the cashier should expect to find a customer that makes a purchase.
1 ➗ 0.74 = 1.35
Part B)
0.013 is the probability that the cashier helps 3 customers until he finds the first person to make a purchase.
(1 - 0.74)3 x 0.74 = 0.013
The difference of the square of a number and 40 is equal to 3 times that number. Find the positive solution.
Answer: The answer is 8.
Step-by-step explanation: The first step is to convert the expression into figures. We shall call the unknown number Y. So if we are told “the square of a number,” that means Y squared, or better still, Y^2. Further we are told “the difference between the square of a number and 40” and that can be written as;
Y^2 - 40.
Next we are told that this expression is equal to 3 times that number (that is 3Y). That can now be written out as follows,
Y^2 - 40 = 3Y
If we move all expressions to one side of the equation, what we would have is,
Y^2 - 3Y -40 = 0
(Remember that when a positive value crosses to the other side of an equation it becomes negative and vice versa)
We now have a quadratic equation
Y^2 -3Y - 40 = 0
By factorizing we now have
(Y -8) (Y + 5) = 0
Therefore Y - 8 = 0 or
Y + 5 = 0
Hence, Y = 8 or Y = -5
Since we are asked to calculate the positive solution, Y = 8
Factor the polynomial completely x2+18
The polynomial x^2 + 18 cannot be factored over the real numbers and remains in its simplest form. For complex coefficients, it can be expressed as (x + 3i)(x - 3i). For cubic differences like x^3 - y^3, the real factors would be (x - y)(x^2 + xy + y^2).
Explanation:The polynomial x2 + 18 cannot be factored over the reals because it does not have any real roots; thus, it is already in simplest form over the real numbers. However, if we allow for complex coefficients, we can write this as (x + 3i)(x - 3i), where i is the imaginary unit. Note, for more complex expressions such as x3 - y3, you would use the formula (x - y)(x2 + xy + y2) to factor it over the reals or apply complex coefficients if necessary.
