Answer:
It would be a point which is at (-4,-7).
The image of the point (4,-7) after a reflection over the y-axis is (-4,-7). This happens because the y-axis is the axis of symmetry during a reflection over this axis, changing the x-coordinate's sign while keeping the y-coordinate constant.
Explanation:The image of a point after a reflection over the y-axis results in the x-coordinate of the point changing its sign. Therefore, the image of the point (4,-7) after a reflection in the y-axis would be (-4,-7). In other words, you move the point 4 units to the left across the y-axis while the y-coordinate remains unchanged.
This process is derived from the concept that the y-axis is the axis of symmetry in a reflection over the y-axis. As such, points on one side of the axis are mirrored on the other side, changing only the sign of the x-coordinate and keeping the y-coordinate constant.
A helpful way to visualize this is by drawing a coordinate grid and plotting the point (4,-7). By reflecting this point over the y-axis, you will see it lands at the point (-4,-7).

HAVE A NICE DAY!
THANKS FOR GIVING ME THE OPPORTUNITY TO ANSWER YOUR QUESTION.
The product of 4.5 ⋅ 105 and 1.6 ⋅ 102 is 7.2 ⋅ 107. This is achieved by first multiplying the coefficients (4.5 and 1.6), and then adding the powers of 10 (105 + 102).
Explanation:First, to multiply these numbers in scientific notation, we begin by multiplying the coefficients and then add up the powers of 10.
So, 4.5 ⋅ 1.6 = 7.2 and then 105 + 102 = 107. Therefore, the product of 4.5 ⋅ 105 and 1.6 ⋅ 102 is 7.2 ⋅ 107. This means it is the second option listed in your potential multiple choice answers above.

Which of the following points is on the circle given
by the equation (x − 5)2 + (y + 3)2 = 25?
A. (5, −3)
B. (8, −6)
C. (2, 1)
D. (4, −8)
Final answer:
The correct point that lies on the circle defined by the equation (x − 5)² + (y + 3)² = 25 is point C (2, 1), as substituting these values into the equation results in 25, which matches the right side of the equation. Thus, option C is correct.
Explanation:
To find which point is on the circle given by the equation (x − 5)² + (y + 3)² = 25, you can plug the x and y values from each option into the equation and see if it holds.
For point A (5, − 3), the equation becomes (5 − 5)² + (− 3 + 3)², which simplifies to 0 + 0 = 0. This is not equal to 25, so point A is not on the circle.
For point B (8, − 6), the equation becomes (8 − 5)² + (− 6 + 3)², which simplifies to 9 + 9 = 18. This is not equal to 25, so point B is not on the circle.
For point C (2, 1), the equation becomes (2 − 5)² + (1 + 3)², which simplifies to 9 + 16 = 25. This is equal to 25, so point C is on the circle.
For point D (4, − 8), the equation becomes (4 − 5)² + (− 8 + 3)², which simplifies to 1 + 25 = 26. This is not equal to 25, so point D is not on the circle.
The correct answer is point C (2, 1), as it satisfies the equation of the circle.

Prove that in the plane the perpendicular bisector of a chord in a circle contains the center of the circle
The perpendicular bisector of a chord in a circle contains the center of the circle.
Explanation:To prove that the perpendicular bisector of a chord in a circle contains the center of the circle, we can use the fact that the perpendicular bisector of a chord passes through the center of a circle.
Let ABC be a chord in a circle with center O. We want to show that the perpendicular bisector of AB passes through O.
Since AB is a chord, it intersects the center O. Let P be the midpoint of AB. The line segment OP is a radius of the circle, and the line segment AB is perpendicular to OP at P. Therefore, the perpendicular bisector of AB passes through O, the center of the circle.

The amount of the IRS fee you will have to pay is A. $750.00.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Percentage is usually denoted by the symbol '%'.
Given that,
Amount you invested at the age of 40 = $20,000
You will receive payments at the age of 50.
Amount withdrawn at the age of 47 = $7500
IRS charges 10% if you withdraw before you are 59.5.
Since your age is 47, you have to pay 10% IRS fees.
IRS fees = 10% of 7500
= 10/100 × 7500
= $750
Hence the IRS fee you will have to pay is A. $750.00.

Consider the quadrilateral below. What is the measure of angle Z
A:24
B:58
C:68
D:112
Answer:
Option C
Step-by-step explanation:
If angle w is 112, angle x has to also be 112
so 112+112=224
all of the angles summed up has to 360, so you subtract 360-224
which equals 136
then divide by 2 and you get 68
Hopefully this makes sense
Answer:
The answer is C: 68
Step-by-step explanation:
The trapezoid has a total amount of 360 degrees.
W = 112 degrees.
W and X are congruent so X also equals 112
SO if you add them together, it is equal to 224.
Subtract from 360 and 136 is left.
Divide by 2 because there is Z and Y(2 angles left) which are also congruent.
This gives the angles measurements of 68 for both Z and Y

q= 5/5
q = -5/5
q=375
q=-3/5
q = 2575
Answer:
None of the options are correct
Step-by-step explanation:
Given
[tex]f(q) = q^2 - 125[/tex]
Required
The roots of the function
Since the function is a quadratic function; to get the roots of the function, f(q) must be equal to 0
[tex]f(q) = q^2 - 125[/tex] becomes
[tex]0 = q^2 - 125[/tex]
Make [tex]q^2[/tex] the subject of formula
[tex]125= q^2[/tex]
Rearrange
[tex]q^2 = 125[/tex]
Take square roots of both sides
[tex]\sqrt{q^2} = \sqrt{125}[/tex]
[tex]q = \sqrt{125}[/tex]
Expand the square root of 125
[tex]q = \sqrt{25 * 5}[/tex]
[tex]q = \sqrt{25} * \sqrt{5}[/tex]
q = ±5 [tex]* \sqrt{5}[/tex]
Split into 2
[tex]q = 5 * \sqrt{5}[/tex] or [tex]q = -5 * \sqrt{5}[/tex]
[tex]q = 5 \sqrt{5}[/tex] or [tex]q = -5 \sqrt{5}[/tex]
Hence, the roots of the quadratic function are [tex]q = 5 \sqrt{5}[/tex] or [tex]q = -5 \sqrt{5}[/tex]

Answer:
127.4
Step-by-step explanation:

The side f will be 127.41 cm long.
What is cosine law?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.
Given is triangle DEF, we need to find the length of the side f, if d = 92 cm, e = 42 cm and ∠F = 141°.
So, using the cosine law,
[tex]c^2=a^2+b^2-2ab\cdot \cos \left(\gamma \right)[/tex]
Therefore,
[tex]f=\sqrt{d^2+e^2-2de\cos 141_{\degrees}[/tex]
[tex]f=\sqrt{42^2+92^2-2\cdot \:42\cdot \:92\cos \left(141^{\circ \:}\right)}[/tex]
f = 127.41
Hence the side f will be 127.41 cm long.

A. $22,097.15
B. $22,044.21
C. $7,097.15
D. $7,044.21
E. None of them
She will gain $ 6885.4896 after 10 years if she chooses 3.85% account.
Step-by-step explanation:
Given,
Principle (P) = $ 15000
Time (T) = 10 years
Rate of interest (R) = 3.85%
To find the compound interest.
Formula
CI = [tex]P(1+\frac{R}{100} )^{T}-P[/tex]-P
Putting the values we get,
CI = [tex]15000(1+\frac{3.85}{100} )^{10}-15000[/tex]
= 21885.4896-15000
= 6885.4896

Ms. Lanigan rolls a fair die 300
times. How many times does she roll an even
number, theoretically and experimentally?
Should be around 150 as 3/6 of the numbers on a die are even so thats 1/2 and 300x(1/5) or just 300x0.5 or just 300/2 equals to 150
Theoretically, it would be 150 times that it rolls even. For half of the dice's sides being even and an equal chance of it landing on any of them.
Experimentally, it could be anything between 0-300, although after so many trails in it, it would be extremely likely that it would be near 150.
If it was only 10 trials of instance it would likely have a greater margin of difference compared to the theoretical probability.
The length of a rectangle is 4 feet less than 3 times its width. The perimeter of the rectangle
is 54 feet. Which equation can be used to find the width (w) of the rectangle?
Final answer:
To find the width (w) of the rectangle, set up an equation using the given information and the formula for the perimeter of a rectangle. Solve the equation to find the width.
Explanation:
To find the width (w) of the rectangle, we can set up an equation based on the given information and the formula for the perimeter of a rectangle. Let's start by assigning variables: let w be the width of the rectangle and let l be the length of the rectangle. According to the problem, the length of the rectangle is 4 feet less than 3 times its width. So we have the equation l = 3w - 4. The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter. Since the perimeter is given as 54 feet, we have the equation 54 = 2(l + w). We can substitute the expression for l from the first equation into the second equation: 54 = 2((3w - 4) + w). Simplifying this equation will allow us to solve for the width (w) of the rectangle.
