Anthony want to have $250,000 in 8 years. If her account is paying 14% interest compounded continuously, how much should she invest in now?
The principal investment required to get a total amount of $250,000.00 rounded to the nearest cent is $81569.95.
What is the principal investment required to get the given accrued amount?The formula for calculating compound interest is expressed as;
A = P(1 + r/n)^(n*t)
P = A / e^(r*t) compounded continuously
Given the data in the question;
Accrued amount A = $250,000Time t = 8 yearsAnnual interest = 14% = 14/100 = 0.14compounded continuouslyPlug the given values into the equation above and solve for P
P = A / e^(r*t)
P = 250,000 / e^( 0.14 × 8 )
P = 250,000 / e^( 1.12)
P = 250,000 / e^( 1.12)
P = $81569.95
Therefore the principal investment required to get a total amount of $250,000.00 rounded to the nearest cent is $81569.95.

write an equation of a line passing through the point (-1,3) and parallel to AB with A(3,-5) and B (-2,15)
Answer:
y = -4x - 1
Step-by-step explanation:
Let's first find the equation of the line segment AB. The equation of a line in slope-intercept form is y = mx + b where m represents the slope and b represents the y-intercept. Start by finding the slope.
Finding the Slope of ABThe equation for slope is: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. These variables represent any pair of coordinates on the line. In this case since the two points chosen are A and B, thus:
[tex]x_2=-2\\x_1=3\\y_2=15\\y_1=-5[/tex]
If we plug these values into the equation, we get:
[tex]\frac{15-(-5)}{-2-3}=\frac{20}{-5}=-4[/tex]
Now we need to find the equation of a line that passes through the point (-1, 3) and is parallel to AB. If two lines are parallel they share the same slope. The equation of the line parallel to AB is y = -4x + b. We can plug in the coordinate (-1, 3) into the equation to solve for b.
Solving for the y-intercept[tex]y = mx+b\\3 = -4(-1) +b\\3=4+b\\\text{Subtract 4 from both sides}\\b=-1[/tex]
Therefore the equation of the line that passes through the point (-1, 3) and is parallel to AB is y = -4x - 1.

If m/DKL = (21x + 5)°, m/JKD = (4x + 2)°,and m/JKL = 132º, find
MZDKL
Finding the missing angle of the figure, the value of m∠DKL is 110°
Describe angle.Two rays that have a common endpoint and are referred to as the angle's sides and vertices, respectively, form an angle. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These angles are dihedral.
given,
m∠DKL = (21x + 5)°
m∠JKD = (4x + 2)°
and
m∠JKL = 132°
By angle sum property of angles
m∠DKL + m∠JKD = m∠JKL
substituting the values, we get
(21x + 5)° + (4x + 2)° equals 132°
(21x + 4x + 5 + 2)° = 132°
(25x + 7)°= 132°
(25x)° = 132° - 7°
x = 125° / 25°
x = 5
now, the value of m∠DKL
m∠DKL = [21 (5) + 5]°
m∠DKL = 105° + 5°
m∠DKL = 110°
Hence the value of m∠DKL is 110°

write 25:4 and 45:10 as a complex fraction
The required answer for 25:4 and 45:10 as a complex fraction is 1/(4/25) and 1/(2/9).
What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now given ratio are,
25:4 and 45:10
Now converting the given ratio into fraction,
25:4 = 25/4
and,
45:10 = 45/10
Now for 25/4 we have,
Numerator = 25
Denominator = 4
Now dividing numerator and denominator by 25 we get,
Numerator = 25/25 = 1
Denominator = 4/25
Thus, the complex fraction of 25/4 we get is,
25/4 = 1/(4/25)
Similarly for 45/10
Numerator = 45
Denominator = 10
Now dividing numerator and denominator by 45 we get,
Numerator = 45/45 = 1
Denominator = 10/45 = 2/9
Thus, the complex fraction of 25/4 we get is,
45/10 = 1/(2/9)
Thus, the required answer for 25:4 and 45:10 as a complex fraction is 1/(4/25) and 1/(2/9)

The angle of elevation made from the eyes of the observer to the top of the tower is 45°.
What is defined as the term angle of elevation?The angle of elevation is the angle formed by the horizontal line of sight and the upward line of sight.
For the given question;
The height of the observer is 1.5 meters.The height of the tower is given as 22 meters.The distance of the tower from the observer is 20.5 meter.The angle of elevation of the top of the tower to the eyes of the observer is needed.
Thus, for this subtract the height of the observer to the height of tower;
height from the eyes to the tower is 22 - 1.5 = 20.5 m.
Thus, apply the trigonometric rule to calculate the angle;
tan Ф = perpendicular/base
perpendicular is the height of tower from the eyes of boy = 20.5 meter.
base is the distance of the tower from the boy = 20.5 meter.
Put the values;
tan Ф = 20.5/20.5
tan Ф = 1
Ф = 45°.

a) The graph will have a "V" shape, which opens upwards.
b) The horizontal shift of 1 unit to the left.
c) The vertical shift is of 5 units downwards.
How to describe the graph of the absolute value function?
Here we have the absolute value function:
f(x) = |x + 1| - 5
First we want to describe the graph shape, we know that it is an absolute value function, so it will have a "V" shape.
The arms will make an angle of 45° with the vertical and horizontal (because the slope is 1)
And it will open upwards, because the slope is positive.
Now, remember that if the parent function is:
f(x).
A translation is written as:
g(x) = f(x + a) + b
Where a is the horizontal translation and b is the vertical translation, such that:
a < 0, translation to the right.a > 0, translation to the left.b > 0 translation up.b < 0 translation down.In this case we have:
f(x) = |x + 1| - 5
So this is a translation of 1 unit to the left and 5 units down of the parent absolute value function.
b) The horizontal shift of 1 unit to the left.
c) The vertical shift is of 5 units downwards.

Karen while putting a fence around the L shaped garden will need about 22.3 ft which is the exact perimeter of this field, with its dimensions as given as 2.1ft by 7.8ft by 5.5ft by2.7ft of the garden.
In arithmetic, how do you handle perimeter?Any kind of closed path that covers, encircles, or outlines a full one-dimensional length or a two-dimensional shape is called as a perimeter.
The circumference of a circle or an ellipse is referred to as its perimeter. There are varied uses in real life for the perimeter calculations.
For example, in case of a rectangle, there are two equal lengths and two equal widths in a rectangle. Then we must sum up all the lengths of the rectangle’s four sides in order to get its final perimeter.
Since there are like two of each side length, it is easy to accomplish this perimeter by simply adding the length and width and then multiplying the result by two.
In this problem,
Total perimeter = 2.1 + 5.1 + 2.1 + 2.5 + 2.7 + 7.8
= 22.3 ft
Thus, the perimeter has been calculated in total as 22.3 ft.
