To find the other endpoint of the diameter of a circle, you can use the midpoint formula in reverse with the given center and one endpoint. In this case, the coordinates of the other endpoint of the diameter are (5, 7).
The coordinates of the other endpoint of a diameter of a circle given that one endpoint and the center of the circle are known. We know the center of the circle, O, is at (2, 3) and one endpoint of the diameter is at (-1, -1). The diameter of a circle is a straight line through the center connecting two points on the circle. If you have one endpoint (x₁, y₁) and the center (x₂, y₂), the coordinates of the other endpoint (x₃, y₃) can be calculated using the midpoint formula in reverse:
x₃ = 2 × x₂ - x₁
y₃ = 2 × y₂ - y₁
For this circle:
x₃ = 2 × 2 - (-1) = 4 + 1 = 5
y₃ = 2 × 3 - (-1) = 6 + 1 = 7
So, the coordinates of the other endpoint of the diameter are (5, 7).
The newest iPad costs $850 and has a sales tax of 11%. What will be the total cost?
Answer:
$943.5
Step-by-step explanation:
Tax: 11% of 850
11/100 × 850 = 93.5
Total cost = 850 +93.5
= 943.5
A total is $943.50.
To calculate the total cost of the newest iPad including the sales tax, we need to add the tax to the initial price of the product. The iPad costs $850, and the sales tax rate is 11%. To find the tax amount, convert the percentage to a decimal by dividing by 100, which gives us 0.11, and then multiply this by the cost of the iPad.
Sales Tax = iPad Cost x Tax Rate
Sales Tax = $850 x 0.11
Sales Tax = $93.50
Now, to find the total cost, add the initial iPad cost to the sales tax:
Total Cost = iPad Cost + Sales Tax
Total Cost = $850 + $93.50
Total Cost = $943.50
Which of the following is true of functions and their inverses?
The inverse of a quadratic function is not a function.
The inverse of a quadratic function is always a function.
The inverse of a linear function is not a function.
The inverse of a linear function is always a function.
The inverse of a quadratic function is not always a function, as it can assign multiple outputs to a single input. Conversely, the inverse of a linear function is always a function because it strictly assigns one output to each input.
Explanation:The presented statements about the nature of functions and their inverses are particularly related to the definition of a function. A function is a rule which assigns to each input exactly one output. Considering this, the inverse of a quadratic function is not always a function because it can assign multiple outputs (y-values) to a single input (x-value). This is why the graph of a quadratic function doesn't pass the 'horizontal line test', which is a criterion for a graph to represent a function.
On the other hand, the inverse of a linear function is indeed always a function. Because a linear function always assigns exactly one output to each input, its inverse will also satisfy the definition of a function.

2. On a blueprint for a new building, 2 inches = 8 feet. The height of the building on the
blueprint is 9 inches. What is the actual height of the building?
Step-by-step explanation:
By blue print conversion,
2 inches = 8 feet
Therefore, 1 inch = [tex]\frac{8}{2}[/tex] = 4 feet
1 inch = 4 feet
The height of the building on the blueprint = 9 inches
The actual height of the building = 9 * 4 = 36 feet.
Explain how you find m∠3 if m∠5 = 130° and m∠4 = 70°. *
Answer:
The required measure of angle 3 is 60°.
Step-by-step explanation:
We are given to find the measure of angle 3 from the figure if
m∠5 = 130° and m∠4 = 70°.
Let the measure of angle 3 be x°.
From the figure, we note that
angle 5 is an exterior angle and angles 3 and 4 are two remote interior angles of the triangle.
We know that
the measure of an exterior angle to a triangle is equal to the sum of the measures of two remote interior angles.
So, we get
Thus, the required measure of angle 3 is 60°.

A company’s mean salary is $65,000 with a standard deviation of $6,000. What is the probability that an employee makes between $70,000 and $80,000?
Answer:
0.19706
Step-by-step explanation:
-Given the mean salary is $65,000 and the standard deviation is $6,000, the probability of making between $70000 and 80000 can be calculated as:
[tex]P(70000<X<80000)=P(\frac{X_1-\mu}{\sigma}<z<\frac{X_2-\mu})\\\\=P(\frac{70000-65000}{6000}<z<\frac{80000-65000}{6000})\\\\=P(0.8333<z<2.5)\\\\\\=0.99379-0.79673\\\\=0.19706[/tex]
Hence,the probability that an employee makes between $70,000 and $80,000 is 0.19706
Final answer:
To find the probability that an employee makes between $70,000 and $80,000, we calculate the z-scores and use the z-table. The probability is 0.1971.
Explanation:
To find the probability that an employee makes between $70,000 and $80,000, we need to calculate the z-scores and use the z-table.
First, we calculate the z-score for $70,000:
z = (X - μ) / σ
z = (70000 - 65000) / 6000 = 0.8333
Next, we calculate the z-score for $80,000:
z = (80000 - 65000) / 6000 = 2.5
Using the z-table, we can find the probabilities associated with these z-scores. The probability of an employee making less than $70,000 is 0.7967, and the probability of an employee making less than $80,000 is 0.9938. Therefore, the probability of an employee making between $70,000 and $80,000 is:
P(70000 < X < 80000) = P(X < 80000) - P(X < 70000) = 0.9938 - 0.7967 = 0.1971
Which function below will translate f(x) = x2 left 5 units and down 1 unit?
Answer:
its c. trust me
Step-by-step explanation:
The resultant function of the parent function f(x) = x², which is translate left 5 units and down 1 unit, is f(x) = (x+5)^2-1.
What is transformation of a function?Transformation of a function is shifting the function from its original place in the graph.
Types of transformation-
Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph c units down and by replacing parent function with f(x)+c shifts the graph c units up.The given function is,
[tex]f(x) = x^2[/tex]
It has to be translated left 5 units. For this we have to add 5 units in the above function. Thus the function become,
[tex]f(x) = (x+5)^2[/tex]
Now the function is translated down 1 unit. For this we have to substract 1 units outside of the above function. Thus the function become,
[tex]f(x) = (x+5)^2-1[/tex]
Hence, the resultant function of the parent function f(x) = x², which is translate left 5 units and down 1 unit, is f(x) = (x+5)^2-1.

7. A box contains fifteen billiards balls, numbered 1 through 15. Anna draws a ball, records the number, and then returns it to the box. Then Vicki draws a ball. Find the probability of getting a 9 then a 3. *
The probability of first drawing a ball numbered 9 and then drawing a ball numbered 3, with each ball being returned to the box between draws, is 1 in 225.
Explanation:The question is about calculating the probability of two specific events occurring consecutively when drawing billiard balls from a box that contains numbers 1 through 15. We focus on the probability of first drawing a ball numbered 9 and then, after returning it, drawing a ball numbered 3. Since each ball is returned to the box before the next draw, the number of possible outcomes does not change between draws.
For the first draw, the probability of drawing a 9 is 1 out of 15 (since there is one '9' ball and 15 total balls). When the 9 ball is returned, the probability of drawing a 3 on the second draw is also 1 out of 15. Because these two events are independent (the outcome of the second draw does not depend on the outcome of the first), we multiply the probabilities of each event to find the overall probability of both events occurring:
Probability of drawing a 9 and then a 3 = (1/15) * (1/15) = 1/225.
This means there is a 1 in 225 chance of drawing a 9 followed by a 3 when both balls are returned to the box in between draws.

Area of a Rectangle=Length X Width[tex]=3 X 4 =12cm^2[/tex]
Area of the circle =[tex]\pi r^2=\pi X 1^1=3.142cm^2[/tex]
Area of the shaded portion=12-3.142
[tex]=8.86cm^2[/tex]
The area of the shaded region inside the rectangle but outside the circle is 8.86 cm².
Explanation:A circle with a radius of 1 cm sits inside a rectangle with dimensions of 3 cm by 4 cm. To solve this problem, we can use the formula to find the area of a rectangle and the area of a circle.
The area of the rectangle is calculated by multiplying its length by its width, giving us an area of 12 cm². The area of the circle can be found using the formula A = πr², where A represents the area and r represents the radius.
Plugging in the given radius of 1 cm, we find that the area of the circle is π cm², which is approximately 3.14 cm². Therefore, the area of the shaded region (the region inside the rectangle but outside the circle) is 12 cm² - 3.14 cm² = 8.86 cm².

Answer:
(x + 4)(x - 2)
Step-by-step explanation:
For factoring when there's a coefficient on the leading variable, I use the "slip n' slide" method (my teacher called it that, I had no part in naming it), but when that fails, you can use the quadratic formula.
First, you "slip" the leading coefficient to the end, and multiply.
5x² + 10x - 40
x² + 10x - 200
Now, you factor it normally.
x² + 10x - 200
= (x + 20)(x - 10)
Then, you divide the 2nd part in each parentheses with the coefficient you slipped in the beginning. This is super important! I always had trouble remembering this step, so hopefully you won't.
(x + 20/5)(x - 10/5)
= (x + 4)(x - 2)

A giant water lily pad is shaped like a circle with a diameter of up to 9 feet. Find the circumference and area of the pad. Use 3.14 for π. Round to the nearest tenth. Drag and drop the numbers into the boxes to show the circumference and area of the pad.
(fill in the blanks)
The circumference of the lily pad is about [ ] ft.
The area of the lily pad is about [ ] ft^2.
(options for both: 14.1, 63.6, 254.3, 28.3)
Answer:
Circumference of the lily pad is about 28.3 ft
Area of the lily pad is about 63.6 ft²
Step-by-step explanation:
Formula for circumference of circle is,
Circumference = 2 π r
Given that diameter is 9 ft. Therefore radius is half of diameter.
[tex]r=\dfrac{d}{2}[/tex]
Substituting the values,
[tex]r=\dfrac{9}{2}=4.5[/tex]
Also value of π = 3.14
Substituting the value,
C = 2 × 3.14 × 4.5
Simplifying,
C = 28.26 ft
Rounding to nearest tenth value of circumference is C = 28.3 ft.
Formula for area of circle is,
A = π r²
Substituting the values,
A = 3.14 × 4.5²
Simplifying,
A = 63.585 ft².
Rounding to nearest tenth value of area is A = 63.6 ft².
