Jess will retire at about 41.98 years historic or round her forty second birthday.
To calculate how lengthy it will take for Jess's financial savings account to attain one million dollars, we can use the system for compound interest:
A = P(1 + r/n)(nt)
Where:
A = Total quantity (one million bucks in this case)
P = Principal quantity (initial credit score of $50,000)
r = Annual hobby price (9% as a decimal, so 0.09)
n = Number of instances the hobby is compounded per yr (in this case, compounded annually)
t = Number of years
Substituting the given values into the formula, we have:
1,000,000 = 50,000(1 + 0.09/1)(1t)
Simplifying:
20 = (1.09)t
To clear up for t, we want to take the logarithm of each aspects of the equation. Let's use the herbal logarithm (ln) for this calculation:
ln(20) = ln(1.09)t
Using the logarithmic property, we can go the exponent t in front:
ln(20) = t * ln(1.09)
Now we can remedy for t with the aid of dividing each aspects by using ln(1.09):
t = ln(20) / ln(1.09)
Using a calculator, we discover that t ≈ 19.98 (rounded to two decimal places).
Therefore,
It will take about 19.98 years to attain one million bucks in Jess's financial savings account.
To decide at what age Jess will retire, we add the time it takes to attain one million bucks to her preliminary age of 22:
Age at retirement = 22 + 19.98 ≈ 41.98

Write a quadratic equation in standard form that has an axis of symmetry of x=-2and y intercept of 0,6
The quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.
A quadratic equation in standard form is of the form ax² + bx + c, where a, b, and c are constants.
The axis of symmetry of a quadratic equation is given by the line x = -b/2a, so if the axis of symmetry is x=-2, we can set -b/2a = -2, which gives b = 4a.
To find the y-intercept of the quadratic equation, we can set x = 0 and substitute that into the equation: y = a(0)² + b(0) + c = c
So, if the y-intercept is (0,6) then c = 6.
By using above two information, we can write the quadratic equation in standard form as:
a(x+2)² + 4a(x+2) + 6 =0
=> a(x²+4x+4) + 6 = 0
=> a(x²+4x+4) = -6
=> a(x²+4x+4) = -6
=> x² + 4x + 4 = -6/a
=> x² + 4x + 4 = -6/a +10
=> x² + 4x - 6 = 0
So, the quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

What is the equation for the line in slope-intercept form?
Answer: y = 8x
Step-by-step explanation:
The line passes through points (1,8) and (2,16).
Using this, we can first find the slope.
Slope = Δy/Δx = 8/1 = 8
So the slope is 8.
The equation is now
y = 8x + b
Let's use the point (1,8) to find the value of b now.
8 = 8 +b
b = 0
Therefore, y = 8x is the answer.
(you can skip the last step by noticing that the graph passes through the origin)
Answer:
y = 8x
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{8cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.\\\end{minipage}}[/tex]
From inspection of the given graph, two points on the line are:
(0, 0)(2, 16)Substitute the points into the slope formula to find the slope of the line:
[tex]\implies m=\dfrac{16-0}{2-0}=\dfrac{16}{2}=8[/tex]
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
The y-intercept is the y-value of the point where the line crosses the y-axis. From inspection of the given graph, the y-intercept is zero. So b=0.
Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:
[tex]\implies y=8x+0[/tex]
[tex]\implies y=8x[/tex]
Therefore, the equation for the line in slope-intercept form is:
y = 8x3. Choose any two complex numbers z, and z2 and show that the following statements are true for

a. Z₁ + Z₁ and Z₂ + Z₂ are both real numbers.
b. Z₁-Z₁ and 22-Z₂ are both pure imaginary numbers.
c. Z₁ + Z₂ = Z₁ + Z₂
d. Z₁ Z₂ = Z₁ Z2
4. For what complex number z does z=z? Justify your conclusion.
The following statements are true for all the numbers. The proof is shown as follows.
What is an imaginary number?A real number is multiplied by an imaginary unit, I whose feature i2 = 1 defines it as an imaginary number. Bi is an imaginary number, while b2 is its square. For instance, the square of the fictitious integer 5i is 25. Zero is regarded as both real and fictitious by definition.
We know z₁ = a + bi and zbar= a-bi
z1+z1bar=2a that is purely real. Similarly with z2 +z2bar
z1-z1bar=-2bi that is purely imaginary. Similarly with z2-z2bar
Again
z1bar+z2bar= a-bi+c-di
z1+z2(whole bar)=a+c-(b+d)i
Hence Z₁ + Z₂ = Z₁ + Z₂
Similarly

[tex]l=98[/tex]
b) The formula for the perimeter of a rectangle is [tex]P=2l+2w[/tex].
We need to evaluate the width. Lets solve for [tex]w[/tex].
[tex]P=2l+2w[/tex]
Subtract [tex]2l[/tex] from both sides of the equation.

The area of a rectangular parking lot is 8428 m²width of the parking lot is 86 mTo Find : Length of the Parking lot
Length of a rectangle shape can be derived by the formula,
[tex]l = \frac{A}{w}[/tex]
[tex]l = \frac{8428}{86}[/tex]
[tex]l = 98m[/tex]
Hence , the length of a rectangular parking lot is 98m
(b) Given ,
The perimeter of a rectangular pool is 376 mlength of the pool is 99 mTo Find : The width of the rectangular pool
We take the width as variable 'x'
Now we plug it into the perimeter of a rectangle equation
[tex]376 = 2(99 + x)[/tex]
Using distributive property we,
[tex]376 = 198 + 2x[/tex]
We now flip the equation
[tex]2x + 198 = 376[/tex]
[tex]2x = 376 - 198[/tex] ( Transposing into the right hand side)
[tex]2x = 178[/tex]

A farmer decides to start selling his goats at a constant rate per month. After seven months, he has 280 goats left. After eleven months, he has 224 goats left.
If the farmer plotted a straight line graph of how many goats he had left over time, the slope of the line would be -14.
To find the slope of the line representing the number of goats the farmer has over time, we need to use the formula:
slope = (y2 - y1) / (x2 - x1)Where y2 and y1 are the number of goats the farmer has at the end of two different months, and x2 and x1 are the number of months that have passed since he started selling the goats.
In this case:
y2 = 224 (goats left after 11 months)y1 = 280 (goats left after 7 months)x2 = 11 (months)x1 = 7 (months)So the slope of the line is:
slope = (224 - 280) / (11 - 7)slope = -56 / 4 slope = -14The slope of the line is -14, which means that the number of goats the farmer has decreases by 14 goats per month.
It's important to note that when the value of the slope is negative, it means that the line is going down; this means that the farmer is selling goats at a constant rate.

a bag contains 3 red marbles and 4 blue marbles. a marbleis taken at random from the bag and replaced. another marble is taken rom the bag. work out the probability that the 2 marbles taken from the bag are the same colour
The probability that the 2 marbles taken from the bag are the same color is 25/49.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of red marbles = 3
Number of blue marbles = 4
Total marbles = 7
Now,
The probability of taking two blue marbles consecutively with replacement.
= 4/7 x 4/7
= 16/49
The probability of taking two red marbles consecutively with replacement.
= 3/7 x 3/7
= 9/49
Since the two marbles of the same color can be blue or red.
The probability that the 2 marbles taken from the bag are the same color.
= 16/49 + 9/49
= 25/49
Thus,
The probability that the 2 marbles taken are the same color is 25/49.

Explain why Mary is mistaken in her conclusions about ΔABC and ΔXYZ. In writing your response, be sure to explain the difference between similarity and congruence. Also be sure to include important math concepts such as similarity, proportionality, and corresponding sides.
Mary is mistaken in her conclusion that the two triangles are not similar because size does not determine similarity. Similarity is determined by the proportionality of corresponding sides and the congruence of corresponding angles. Congruence is the equality of all the measures of the corresponding parts of two figures.
In order to determine if two triangles are similar, we must compare the ratios of corresponding sides. If the ratios of corresponding sides are equal, then the triangles are similar. In the diagram, it is not specified what the measures of the sides of the triangles are, so it is not possible to determine if the triangles are similar based on the information given. However, if the ratio of corresponding sides are same, then the triangles are similar.
It is important to note that similarity and congruence are different concepts. Congruence refers to the equality of all measures of corresponding parts of two figures, including side lengths and angles. Similarity refers to the proportionality of corresponding parts, including side lengths and angles. A triangle can be similar to another triangle without being congruent, and congruent triangles are always similar.
In summary, Mary is mistaken because the size of the triangle does not determine similarity, it is determined by the proportionality of corresponding sides and congruence of corresponding angles. Without knowing the measures of the sides of the triangles, it is impossible to determine if the triangles are similar based on the information given.
What is midpoint formula Class 11?
The midpoint formula helps us to find the midpoint of a line given to us on a coordinate system.
The coordinate system in geometry is a plane space in which points are located using paired numerical values called coordinates. It is of two types Cartesian coordinate system and polar coordinate system
The cartesian coordinate system is further divided into majorly two parts i.e., 2-Dimensional and 3- dimensional systems. A 2-D system has 2 axis X and Y whereas a 3-D system has X, Y, and Z axes. The plane is divided into 4 quadrants
The midpoint formula is used to find the center of a line or a figure. It is a mathematical equation used in geometry and economics. On a line from point (x1,y1) to (x2,y2) the midpoint P= (x1+y1)/2 , (x2+y2)/2. It divides the line in a 1:1 ratio.

How do you find the coordinates of a midpoint example?
To find the coordinates of the midpoint of two points in a plane, you can use the midpoint formula. The midpoint formula is:
(x,y) = ((x1 + x2) / 2, (y1 + y2) / 2)
Where (x1, y1) and (x2, y2) are the coordinates of the two points, and (x,y) are the coordinates of the midpoint.
For example, if you have two points (3, 4) and (7, 10), you can use the midpoint formula to find the coordinates of the midpoint:
(x,y) = ((3 + 7) / 2, (4 + 10) / 2)
(x,y) = (5, 7)
The midpoint of points (3,4) and (7,10) is (5,7).

In the triangle below, what is the side adjacent?? HELP
Which equation represents a line perpendicular to the line with equation 2x + 3y = 12?.
The equation of the line perpendicular to 2x + 3y = 12 will be y = 3x/2 + c where c ∈ R.
The equation of the line given here is 2x + 3y = 12
Now rearranging it to the slope-intercept form we get
3y = -2x + 12
or, y = -2x/3 + 4
Now any 2 lines are perpendicular when the product of their slopes results in -1.
Hence, let the equation of the line perpendicular to the given line be
y = mx + c, where m is the slope of the line and c is the intercept.
Hence,
-2m/3 = -1
or, m = 3/2
Hence the equation of the line will be
y = 3x/2 + c where c ∈ R

Is y 10 a linear function?
A function y = 10 a not linear function
We know that the general form of linear function is f(x) = a + bx
A linear function has one independent variable (for above function x) and one dependent variable(here, f(x)).
The graph of linear function is always a straight line.
Let y = f(x)
So, y = a + bx
where b is the slope of line
and a is the y-intercept
here, the independent variable is x and the dependent variable is y.
We have been given a function y = 10
The graph of y = 10 is a horizontal line parallel to x -axis and intersects y-axis at (0, 10)
There is no y-intercept and the slope is undefined.
Therefore, given function is not a linear function

What are vertices of a polygon?A vertex is a corner point of a polygon, polyhedron, or other higher-dimensional polytope, formed by the intersection of edges, faces or facets of the object.
The vertices of the polygons are given as B(−2, 2), C(4, −2), D(4, 4) . The polygon is reduced by using a scale factor one fourth. i.e 1/4.
This means that each coordinates of the vertices will be reduced by 4 to give the vertices of the new polygon.
A = (-4,6) , A' = ( -1, 1.5)
B = ( -2,2) B' = ( -0.5, 0.5)
C = ( 4, -2) C' = ( 1, -0.5)
D = ( 4,4) , D' = ( 1, 1)
Therefore the vertices of the new polygon is A′(−1, 1.5), B′(−0.5, 0.5), C′(1, −0.5), D′(1, 1)
