What is simple interest?

A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,

The formula for simple interest is:

S = p*t*r/100

where P is the principal amount of money, R is the interest rate as a decimal, T is the time.

a bond that paid 7.75% simple interest earned $3,875 interest.

S = (3875*7.75*25)/100 = $7507.8125

Hence the interest the bond paid off is $7507.8125.

Write an expression for the distance ?

The length of the line that connects two places serves as the unit of measurement for distance.

By subtracting the different coordinates from the pair if the two points are on the same horizontal or vertical line, the distance can be calculated.

Let x be the first day's ride.

The second ride will then be equal to 1.5 times.

The third day's journey will cost 1.5 (1.5x)

The ride on the fourth day will cost 1.5*1.5. (1.5x)

Consequently, the distance traveled over the four days is

65=x+1.5x+1.5*1.5x+1.5*1.5*1.5x

65=x+1.5x+2.25x+3.375x

65=8.125x

by multiplying both sides by 8.125, we get

x=65/8.125

x=8mile

3. Line segment XY is rotated 90° about the origin , dilated by a scale factor of -1/2, and then reflected in the line x = 5.

Answers

Answer:

1) Quadrilateral ABCD is translated 5 units and 4 units down, then reflected in the y-axis. This will result in congruent figures. Translation only moves the figure without changing the size or shape, and reflection in the y-axis will mirror the figure across the y-axis without altering its size or shape. Since both operations preserve the size and shape of the figure, the resulting figure will be congruent to the original.

2) ΔJKL is dilated by a scale factor of 2 and then rotated 180° about the origin. This will result in congruent figures. Dilation by a scale factor of 2 will double the size of the triangle while maintaining its shape, and rotation by 180° about the origin will flip the triangle over the origin while maintaining its shape. Since both operations preserve the size and shape of the figure, the resulting figure will be congruent to the original.

3) Line segment XY is rotated 90° about the origin, dilated by a scale factor of -1/2, and then reflected in the line x = 5. This will result in similar figures. Rotation by 90° about the origin will rotate the line segment by 90 degrees, dilated by a scale factor of -1/2 will shrink the size by half but with a change in direction and reflection in the line x = 5 will mirror the figure across the x=5 line without altering its size or shape. Since all the operations maintain the shape of the figure but the size changes, the resulting figure will be similar to the original one.

Question 1

Translation and reflection doesn't change the shape or size of the figure, therefore the resulting figure is congruent to the initial one.

Question 2

Rotation doesn't change the shape of the figure, but dilation changes the size, therefore the resulting figure is similar to the initial one.

Question 3

Rotation and reflection don't change, but dilation changes the size, therefore the resulting segment is similar to the initial one.

Divide the following polynomials using synthetic division, then place the answer in the proper location on the grid. Write answer in descending powers of x.

(x4 + 81) / (x + 3)

Answers

The division of the given polynomial would be (x^4) + 81.

What is the synthetic division?

Synthetic division is a method for dividing polynomials that allows you to divide a polynomial by a linear factor (a factor in the form of (x-c) where c is a constant) without actually performing the long division process. It is a short cut method that simplifies the process of dividing polynomials.

To divide the polynomials using synthetic division, we will use the following steps:

Write the polynomials in descending order of exponents. In this case, the given polynomials are already in descending order:

(x^4+ 81) / (x + 3)

Create a grid with the dividend on the left and the divisor on the right.

x^4 81

x 3

Bring down the leading coefficient of the dividend, which is x^4 in this case. Write it in the next row of the grid.

x^4 81

x^4 x 3

Multiply the divisor (x + 3) by the leading coefficient (x^4) and write the result in the next row.

x^4 81

x^4 x 3

x^5 x^5 3x^4

Subtract the second row from the third row and write the result in the next row.

x^4 81

x^4 x 3

x^5 x^5 3x^4

0 81-3x^4

Bring down the next coefficient of the dividend (81) and write it in the next row of the grid.

x^4 81

x^4 x 3

x^5 x^5 3x^4

0 81-3x^4

81

Now we repeat the steps 4-6 for the rest of the coefficients of the dividend, but there is no more coefficients in this example.

The quotient is x^4 and the remainder is 81

So the final answer is:

(x^4)+(81)

Hence, the division of the given polynomial would be (x^4) + 81.

A' = (-4, -3)B' = (1, -1)C' = (-1, 3)

Question 3:

A' = (2, 1)B' = (2, 5)C' = (4, 4)

Step-by-step explanation:

Question 1

Given vertices of the pre-image:

A = (1, 2)B = (1, 5)C = (5, 5)

If the pre-image is reflected in the x-axis, the transformation rule is:

[tex](x,y) \rightarrow (x, -y)[/tex]

Therefore the vertices of the image are:

A' = (1, -2)B' = (1, -5)C' = (5, -5)

Question 2

Given vertices of the pre-image:

A = (4, -3)B = (-1, -1)C = (1, 3)

If the pre-image is reflected in the y-axis, the transformation rule is:

[tex](x,y) \rightarrow (-x, y)[/tex]

Therefore the vertices of the image are:

A' = (-4, -3)B' = (1, -1)C' = (-1, 3)

Question 3

Given vertices of the pre-image:

A = (2, 1)B = (2, -3)C = (4, -2)

If the pre-image is reflected in the line y = 1, the transformation rule is:

[tex](x,y) \rightarrow (x,y+2|y-1|)[/tex]

Therefore the vertices of the image are:

A' = (2, 1)B' = (2, 5)C' = (4, 4)

Answers

Answer: Tina has read 16 pages and reads 22 pages per day until the book is finished.

Zuri has read 24 pages and reads 18 pages per day until the book is finished.

We can use this information to set up an equation to represent the number of pages read by each student over a certain number of days.

Let's call the page number they are on when they read the same amount of the book "p"

We can set up the equation as follows:

16 + 22d = 24 + 18d = p

Now we can solve for p by combining like terms:

16 + 22d = 24 + 18d

4d = 8

d = 2

Now we know that it takes 2 days for Tina and Zuri to read the same amount of the book.

Now we can use this value of d to find out what page they are on when they read the same amount of the book.

p = 16 + 22*2 = 16 + 44 = 60

So Tina and Zuri are on page 60 when they have read the same amount of the book.

A game room has a floor that is 450 feet by 20 feet. A scale drawing of the floor on grid paper uses a scale of 1 units feet. What are the dimensions of the scale drawing? Enter your answer as length by width. The scale drawing is units by units.​

Answers

A scale drawing is a representation of an object or space that is reduced or enlarged in proportion to the actual object or space. In this case, the scale of the drawing is 1 unit = 1 foot. To find the dimensions of the scale drawing, we need to divide the actual dimensions of the room by the scale of the drawing.

The actual dimensions of the floor are 450 feet by 20 feet.

So, the dimensions of the scale drawing are:

450 feet / 1 unit = 450 units (length)

20 feet / 1 unit = 20 units (width)

Therefore, the dimensions of the scale drawing are 450 units by 20 units. So, the scale drawing is 450 by 20.

Answer:

130°

Step-by-step explanation:

Since QS bisects ∠PQR, the measures of angles PQS and SQR must be the same

m ∠PQS = 3x + 5

m ∠SQR= 2x + 25

Setting these expressions equal to each other:
3x + 5 = 2x + 25

Subtract 2x from both sides

3x - 2x + 5 = 25

x + 5 = 25

Subtract 5 from both sides

x = 20

Therefore m ∠PQS which is  3x + 5:

m ∠PQS = 3(20) + 5 = 65°

m ∠SQR = ∠PQS =65°  also

Adding the two together we get

m ∠PQR = 65 + 65 = 130°

In the University belt, the traffic lights at three different road crossings
change after every 36 seconds, 64 seconds and 110 seconds, respectively. If
they change simultaneously at 11 a.m., at what time will they change
simultaneously again?

Answers

Answer:

  7:48 p.m.

Step-by-step explanation:

You want to know when lights with periods 36 s, 64 s, and 110 s will change simultaneously again if they do so at 11 a.m..

LCM

The lights will change simultaneously after a time that is the least common multiple (LCM) of the periods of the lights.

The least common multiple is the product of the unique factors in each of the numbers:

  36 = 2² · 3²

  64 = 2⁶

  110 = 2 · 5 · 11

The unique factors are 2⁶, 3², 5, and 11. Their product is 31680. The lights will change simultaneously again after 31680 seconds.

Time conversion

We can convert this to hours, minutes, and seconds by repeated division by 60:

8 = 1/3(a + 5) pls answer fast

Answers

Answer:

19

Step-by-step explanation:

8 = 1/3 (a+5)

24 = a + 5

=> a = 19

Answer:

[tex]a=19[/tex]

Step-by-step explanation:

[tex]8=\frac{1}{3} (a+5)[/tex]

To find the answer we have to find the value of the variable. In order to find the value of the variable we need to isolate it from the equation.

[tex]8=\frac{1}{3} (a+5)[/tex]
[tex]\frac{1}{3} (a+5)=8[/tex]
Multiply 3 on both sides:
[tex]8\times3=24[/tex]
[tex](a+5)=24[/tex]
Subtract both sides by 5:
[tex]24-5=19[/tex]
[tex]a=19[/tex]

Therefore your answer is "a = 19."

Hope this helps.

Let w=2+i and z be nonzero complex number. If the argument of z is pi/4 and |x-w| =sqrt(5) , what is | z |^2

Answers

Answer:

Step-by-step explanation:

?

|z|^2 = |z|*|z| = (|z|)^2

Since the argument of z is pi/4, z can be written as z=r*(cos(pi/4)+i*sin(pi/4)) where r is the magnitude of z.

We also know that |x-w| =sqrt(5).

This means that |z-w| = sqrt(5).

Substituting the expression for z, we get:

|r*(cos(pi/4)+i*sin(pi/4))-w| = sqrt(5)

Simplifying this equation, we get:

|r-2-i| = sqrt(5)

Squaring both sides, we get:

(r-2-i)(r-2+i) = 5

Simplifying, we get:

r^2-4+i(2r-2)=5

Equating the real and the imaginary parts, we get:

r^2-4 = 5

and

2r-2=0

Solving these equations simultaneously, we get:

r = sqrt(9)

Therefore,

|z| = sqrt(9)

Hence,

|z|^2 = (sqrt(9))^2 = 9

The complex number in rectangular form is z = √2 - i√2

What is rectangular form of complex numbers?

The rectangular form of of a complex number is given by z = a + ib where

a = rcosФ and b = rsinФ

where

r = magnitude of complex number and Ф = argument of complex number

How to find the given complex number in rectangular form?

Given the complex number

z = 2[cos(- π/4) + isin(- π/4)] , we desire to find the rectangular form of the complex number. We proceed as follows.

z = 2[cos(- π/4) + isin(- π/4)]

z = 2cos(- π/4) + i2sin(- π/4)]

z = 2cos(π/4) - i2sin(-π/4)]

Since cos(π/4) = sin(π/4) = 1/√2, we have that

z = 2cos(π/4) - i2sin(-π/4)]

z = 2 × 1/√2 - i2 × 1/√2

z = 2/√2 - i2/√2

Rationalizing the denominators, we have that

z = 2/√2 × √2/√2 - i2/√2 × √2/√2

z = 2√2/2 - i2√2/√2

z = √2 - i√2

So, we have the number in rectangular form as z = √2 - i√2
