The coordinates of the image of EB are (0, -1) and (-6, 18).
What is dilation?Dilation is a process for creating similar figures by changing the dimensions.
The center of dilation is given as (3, -1) and the scale factor is 3.
The distance between the center of dilation and point E is:
d = √((3-2)² + (-1-(-1))²) = 1
The distance between the center of dilation and point B is:
d = √((3-0)² + (-1-5)²) = sqrt(65)
To find the new distance, we multiply the distance by the scale factor:
For point E: 3 × 1 = 3
For point B: 3 × √(65)
Now, we can find the coordinates of the image:
For point E:
x = 3 × (2 - 3) + 3 = -3 + 3 = 0
y = 3 × (-1 -(-1)) -1 = 0 - 1 = -1
So the image of E is (0, -1).
For point B:
x = 3 × (0 - 3) + 3 = -9 + 3 = -6
y = 3 × (5 -(-1)) -1 = 18
So the image of B is (-6, 18).
Therefore, the coordinates of the image of EB are (0, -1) and (-6, 18).

Step-by-step explanation:
17.25x+3.89=21.14
17.25x=17.25
x = 1
Answer:
The solution to the equation is x = 1
Step-by-step explanation:
Hi,
We need to isolate the term that contains the variable "x", so we will subtract 3.89.
17.25x + 3.89 - 3.89 = 21.14 - 3.89
We obtain:
17.25x = 17.25

Tell whether each scale reduces enlarges or preserves the size of an actual object
1 cm:12 m
6 ft: 10 in
1km : 1000 m
Answer and Step-by-step explanation:
1 cm: 12 m
This scale reduces the size of an actual object. For example, if a car is 4 meters long in real life, it would be represented as 0.33 cm on a map that uses this scale (4 meters divided by 12).
6 ft: 10 in
This scale enlarges the size of an actual object. For example, if a room is 10 feet wide in real life, it would be represented as 60 inches on a blueprint that uses this scale (10 feet multiplied by 6).
1 km: 1000 m
This scale preserves the size of an actual object. For example, if a park is 2 kilometers wide in real life, it would be represented as 2000 meters on a map that uses this scale.
A container built for transatlantic shipping is constructed in the shape of a right
rectangular prism. Its dimensions are 2.5 ft by 13.5 ft by 9 ft. If the container is
entirely full and, on average, its contents weigh 0.28 pounds per cubic foot, find the
total weight of the contents. Round your answer to the nearest pound if necessary.
The volume of a right rectangular prism is given by the formula below
[tex]V=whl[/tex]
Thus, in our case,
[tex]V=2.5\times13.5\times9=303.75[/tex]
The volume of the container is 1116.5ft^3.
Finally, multiply the total volume by the density given in the problem, as follows
[tex]weight=303.75\times0.28=85.05[/tex]
⇒ [tex]weight[/tex] ≈ [tex]85[/tex]
Rounded to the nearest pound, the answer is 85 pounds.

steve earns $255.75 a week. He is single.and claims 2 allowances. What amount is withheld for federal income tax
Answer:
$445.10
Step-by-step explanation:
The amount withheld for federal income tax depends on several factors, including Steve's filing status, income, and deductions. However, we can make an estimate based on some assumptions.
Assuming Steve is paid weekly and is paid for 52 weeks a year, his gross income would be:
$255.75 x 52 = $13,293
We also assume that Steve is claiming two allowances. Each allowance reduces the amount of taxable income subject to federal income tax withholding. For 2021, each allowance is equal to $4,300.
Therefore, Steve's taxable income for federal income tax purposes would be:
$13,293 - (2 x $4,300) = $4,693
To estimate the federal income tax withholding, we can use the IRS tax tables. For a single person claiming two allowances and earning $4,693 per week, the estimated federal income tax withholding would be:
$445.10
However, this is just an estimate, and the actual federal income tax withholding may be different based on Steve's specific circumstances. It's always best to consult with a tax professional for accurate tax advice.
Rewrite the quantity as an algebraic expression of \( x \) and state the domain on which the equivalence is valid. \[ \cot (\arcsin (x))=\sqrt{\frac{\sqrt{1-x^{2}}}{x}} \] Domain:
The domain of the expression is \( [-1,1] \).
To rewrite the quantity as an algebraic expression of \( x \), we need to use the definition of the cotangent function and the relationship between the sine and cosine functions. The cotangent function is defined as \[ \cot (\theta)=\frac{1}{\tan (\theta)}=\frac{\cos (\theta)}{\sin (\theta)} \]Using the relationship between the sine and cosine functions, \[ \cos^{2} (\theta)=1-\sin^{2} (\theta) \]we can rewrite the cotangent function in terms of the sine function as \[ \cot (\theta)=\frac{\sqrt{1-\sin^{2} (\theta)}}{\sin (\theta)} \]Substituting \( \arcsin (x) \) for \( \theta \) gives us \[ \cot (\arcsin (x))=\frac{\sqrt{1-\sin^{2} (\arcsin (x))}}{\sin (\arcsin (x))} \]Since \( \sin (\arcsin (x))=x \), we can simplify the expression to get \[ \cot (\arcsin (x))=\frac{\sqrt{1-x^{2}}}{x} \]This is the algebraic expression of the quantity in terms of \( x \).
The domain of the expression is the set of values of \( x \) for which the expression is defined. Since the expression involves a square root, we need to ensure that the radicand is non-negative. This gives us the inequality \[ 1-x^{2}\geq 0 \]Solving for \( x \) gives us the inequality \[ -1\leq x\leq 1 \]Therefore, the domain of the expression is \( [-1,1] \).
In conclusion, the quantity can be rewritten as an algebraic expression of \( x \) as \[ \cot (\arcsin (x))=\frac{\sqrt{1-x^{2}}}{x} \]and the domain on which the equivalence is valid is \( [-1,1] \).

If cot (x) = 5/3 (in Quadrant-I), find
sin(2x) = _________ (Please enter answer accurate to 4 decimal places.)
The answer is sin(2x) = 0.8824.
If cot(x) = 5/3, we can use the identity cot(x) = 1/tan(x) to find the value of tan(x). Therefore, tan(x) = 1/(5/3) = 3/5.
Now, we can use the identity sin(2x) = 2sin(x)cos(x) to find the value of sin(2x). First, we need to find the values of sin(x) and cos(x).
Since tan(x) = 3/5, we can use the Pythagorean identity 1 = sin^2(x) + cos^2(x) to find the values of sin(x) and cos(x).
Let's assume sin(x) = 3/a and cos(x) = 5/a. Then, we can plug these values into the Pythagorean identity and solve for a:
1 = (3/a)^2 + (5/a)^2
1 = 9/a^2 + 25/a^2
1 = 34/a^2
a^2 = 34
a = √34
Therefore, sin(x) = 3/√34 and cos(x) = 5/√34.
Now, we can plug these values into the identity sin(2x) = 2sin(x)cos(x) to find the value of sin(2x):
sin(2x) = 2(3/√34)(5/√34)
sin(2x) = 30/34
sin(2x) = 0.8823529411764706
To 4 decimal places, sin(2x) = 0.8824.
the answer is sin(2x) = 0.8824.

You have a negative bank balance of $75. You deposit $6.50 per day and now has a positive bank balance of $81. How many days did it take her to reach $81?
It took 24 days for the bank balance to increase from -$75 to $81 with daily deposits of $6.50.
How to determine the number of daysLet's start by figuring out how much the bank balance increased by each day.
If the starting bank balance was -$75 and the ending bank balance was $81, then the total increase was:
$81 - (-$75) = $156
If she deposited $6.50 per day, then the bank balance increased by $6.50 each day.

f(x) = ax^2 + bx + c
where;
a, b, and c are constants.To graph a quadratic function, you can follow these steps:
Determine the vertex of the parabola. The vertex is the highest or lowest point on the parabola and is given by the formula:x = -b / 2a
y = f(x)
You can find the x-coordinate of the vertex by using the formula above, and then substitute it into the function to find the corresponding y-coordinate.
Determine the y-intercept of the parabola. The y-intercept is the point where the parabola intersects the y-axis, and it can be found by setting x = 0 in the function and solving for y.Find the x-intercepts of the parabola, if they exist. The x-intercepts are the points where the parabola intersects the x-axis, and they can be found by setting y = 0 in the function and solving for x. If the discriminant (b^2 - 4ac) is negative, then the parabola does not intersect the x-axis.Plot the vertex, y-intercept, and any x-intercepts on a coordinate plane. The vertex is the highest or lowest point on the parabola and is located on the axis of symmetry, which is the vertical line passing through the x-coordinate of the vertex.Draw the parabola by sketching a smooth curve through the points you've plotted.
