The principal and coupon payment made on January 15, 2020 would be calculated based on the difference between the CPI on the date of issue and the CPI on due time January 15, 2020.

Using the values given, the principal and coupon payment would be equal to the original principal and coupon multiplied by the ratio of the two CPI values. Therefore, the principal and coupon payment would be equal to (CPI on date of issue/CPI on January 15, 2020) * (original principal + coupon).

1. Calculate the ratio of the two CPI values by dividing the CPI on the date of issue by the CPI on January 15, 2020 with time:

ratio = (CPI on date of issue / CPI on January 15, 2020)

2. Multiply the original principal and coupon by the ratio from step 1:

principal and coupon payment = (ratio) * (original principal + coupon)

Ana should choose option (a) because she pays the least in interest.

To determine which option would be the most cost-effective for Ana, you need to consider the total amount of interest she would pay over the course of the loan.

Option (a) is monthly simple interest, which means that the interest is calculated on the principal balance of the loan at the end of each month, based on the annual interest rate. Option (b) is quarterly compound interest, which means that the interest is compounded and added to the principal balance of the loan at the end of each quarter. Option (c) is continuous compound interest, which means that the interest is compounded continuously, rather than at fixed intervals.

Using the formula for simple interest, the total amount of interest that Ana would pay over the course of the loan under option (a) is:

$166.25 = $5,000 * 3.99% * 10

Answer:

-3

Step-by-step explanation:

The formula for the rate of change (slope) between two points is:

[tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]      
So, we plug in the two points:

[tex]\frac{-20-(-5)}{6-1} =\frac{-15}{5} =-3[/tex]
The rate of change is -3

The slope intercept form of the equation is y = -1/3 x - 13/3

What is an equation of a line?

The set of points that make up a line in a coordinate system are represented algebraically by a line's equation. An equation of a line is an algebraic expression that represents the many points that together make up a line in the coordinate axis as a set of variables, x, and y.

Given equation of the line is y = 3x - 5 .

Compare the equation with y = mx + c

m = 3 and c = -5

The slope of the line that perpendicular to the given line is - 1/m = - 1/3

The equation of line that passes through the point (x₁, y₁)  with slope m is y -  y₁ = m (x - x₁).

Given point is (8,-7).

Putting m = - 1/3, x₁ = 8, y₁ = -7 in y -  y₁ = m (x - x₁):

y -  (-7) =  - 1/3 (x - 8)

Rewrite the above equation in the form y = mx + c:

y + 7 = -1/3 m + 8/3

Subtract 7 from both sides:

y  = -1/3 m + 8/3 - 7

y  = -1/3 m - 13/3

To solve this problem, we can use the Pythagorean theorem to find the height of the balloon. In particular, we can consider the right triangle formed by the stake, the top of the balloon, and the part of the string that is attached to the stake.

[asy]

unitsize(2 cm);

pair A, B, C, D, E;

A = (0,0);

B = (0,8);

C = extension(A,B,A+(1,0),B+(1,0));

D = extension(A,C,A+(0,1),C+(0,1));

E = extension(B,D,B+(0,-1),D+(0,-1));

draw(A--B--C--cycle);

draw(A--D--E--cycle);

draw(rightanglemark(A,D,C,2));

label("$A$", A, S);

label("$B$", B, N);

label("$C$", C, E);

label("$D$", D, E);

label("$E$", E, W);

[/asy]

Let $a$ be the distance from the stake to the top of the balloon, $b$ be the height of the balloon, and $c$ be the length of the string. We know that $a = 8$ feet and $c = 15$ feet, so we can use the Pythagorean theorem to find $b$:

$a^2 + b^2 = c^2$

$8^2 + b^2 = 15^2$

$64 + b^2 = 225$

$b^2 = 161$

$b = \sqrt{161} = \boxed{12.8}$ feet

Therefore, the height of the balloon is approximately 12.8 feet.

The correct description will be;

⇒ y = - 2x + 3

4x + 2y = 6

These are independent.

⇒ y = -2x + 3

4x + y = 9

These are consistent.

⇒ y = -2x+3

4x + 2y = 9

These are inconsistent.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expressions are,

1. y = -2x+3

4x + 2y = 6

2. y = -2x+3

4x+y=9

3. y = -2x+3

4x + 2y = 9

Now,

From (1);

1. y = -2x+3

4x + 2y = 6

⇒ 2x + y = 3

4x + 2y = 6

⇒ 2x + y = 3

So We get;

⇒ 2/2 = 1/1 = 3/3

⇒ 1/1 = 1/1 = 1/1

These are independent.

From (2);

1. y = -2x+3

4x + y = 9

⇒ 2x + y = 3

4x + y = 9

So We get;

⇒ 2/4 ≠ 1/1

⇒ 1/2 ≠ 1/1

These are consistent.

From (3);

1. y = -2x+3

4x + 2y = 9

⇒ 2x + y = 3

4x + 2y = 9

So We get;

⇒ 2/4 = 1/2 = 3/9

⇒ 1/2 = 1/2 ≠ 1/3

These are inconsistent.

The percentile rank of a core of 71 in the given test is 26.67% and the score of Viktor for the 60th percentile is 85.

The formula for calculating the percentile rank of a set of data is

percentile rank for 'x' = (number of data values below 'x')/total number of data values × 100 i.e., Percentile rank = n/N × 100.

The formula for calculating the percentile is

percentile = rank × total number of data values

Where rank = percentile ÷ 100

A teacher recorded unit 4 test scores from her class.

The scores data is as follows:

58, 64, 68, 70, 71, 75, 77, 80, 84, 85, 87, 90, 93, 95, 96

So, the total number of data values N = 15

The percentile rank for a score of 71 on this test is

The number of data values below score 71 is n = 4

Then,

Percentile Rank = n/N × 100 = 4/15 × 100 = 26.67%

Viktor's score, when he is in the 60th percentile is

percentile = rank × 15

Rank = 60 ÷ 100 = 0.6

⇒ percentile = 0.6 × 15 = 9

The data value after 9 positions from the left to right in the data set is 85. So, the score in the 60th percentile is below 85.

Answer:

Described below.

Step-by-step explanation:

To graph the solution to an inequality on the number line, we need to determine the values of the variable that satisfy the inequality and then plot those values on the number line. In the given inequality, 35z > 34, we can solve for z by dividing both sides of the inequality by 35 to get:

z > 34/35

This gives us the solution z > 0.96857. To graph this solution on the number line, we can plot a dot at the value 0.96857, which represents the smallest value of z that satisfies the inequality. We can then draw a line segment to the right of this point, indicating that all values of z greater than 0.96857 are also solutions of the inequality. This is shown in the following diagram:

[Insert diagram of number line with dot at 0.96857 and line segment to the right]

As the inequality is strict (i.e., it uses the ">" symbol rather than "≥"), the values of z that exactly equal 0.96857 are not considered to be solutions. Only values of z that are greater than 0.96857 are considered to be solutions of the inequality.

The perimeter of the larger polygon is 45 units.

Answer:

To find the value of r₂, we need to know how the dilations with scale factors r₁ and r₂ affect the coordinates of the point P.

If a dilation with scale factor r₁ maps a point P with coordinates (x, y) to another point P' with coordinates (x', y'), then the coordinates of P' are related to the coordinates of P by the equation:

x' = r₁x

y' = r₁y

Similarly, if a dilation with scale factor r₂ maps a point P' with coordinates (x', y') to another point P'' with coordinates (x'', y''), then the coordinates of P'' are related to the coordinates of P' by the equation:

x'' = r₂x'

y'' = r₂y'

Since we are given that the dilations map P to P and P' to P, we can set the coordinates of P and P'' equal to each other, and the coordinates of P' and P'' equal to each other. This gives us the following system of equations:

x'' = x

y'' = y

x'' = r₂x'

y'' = r₂y'

Substituting the second set of equations into the first set, we get:

x = r₂x'

y = r₂y'

Since we know that the dilation with scale factor r₁ maps P to P', we can substitute the equations for x' and y' into the above equations to get:

x = r₂*(r₁x)

y = r₂(r₁*y)

Solving for r₂, we find that:

r₂ = 1/r₁

Substituting the value of r₁ = 1/4, we find that:

r₂ = 1/(1/4) = 4

So the value of r₂ is 4.

Answer:

Step-by-step explanation:

On a coordinate plane, parallel lines have the same slope as geometric figures are true. Thus option B is correct.

Marks, splines, spheres, and curved are used to build enclosed geometric shapes. We can see these shapes all around us. Illustrations of geometric shapes include circles, rectangles, triangles, and others. Any configuration of points, columns, or angles is a geometry figure.

A point is the most fundamental algebraic concept because it has no boundaries. Simply put, a point upon that plane is a location. A dot is used to symbolize it. A plane can be identified by three non-straight-line points.

As two or much more vectors seldom cross each other and are located on the same dimension, these are said to be parallel. The slope of these lines is constant. Coplanar lines that seem to be parallel are the ones that don't cross. Therefore, option B is the correct option.

the edges of a cube increase at a rate of 5 centimeters per second. The surface area is changing at a rate of 150 cm²/sec.

To calculate the rate at which the surface area of a cube is changing when each edge is 10 cm long, we first need to calculate the surface area of the cube. The surface area of a cube can be calculated by multiplying the length of one edge cubed by 6. In this case, the length of one edge is 10 cm, so the surface area of the cube is 600 cm². Since the edges of the cube are increasing at a rate of 5 cm/sec, the rate at which the surface area of the cube is changing is equal to the surface area multiplied by the rate of increase, or 600 cm² * 5 cm/sec = 300 cm²/sec.
