The standard form of a given number is scientific notation which is given by the form of exponents of ten and written as 5.67 ×10⁵.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

Standard form is a way of writing down in the easy form very large or very small numbers.

Let E is the standard form of a given number

E = 567000

E = 500000 + 67000 + 7000

E = 0.567 × 10⁶ = 5.67 ×10⁵

E = 5.67 × 10⁵

Hence, the standard form of a given number is 5.67 ×10⁵.

The coordinates of Parallelogram CDEF after a reflection across y = x are C'(-1,2), D'(1,7), E(-2,6) and (-4,1)

What does coordinate mean in this case?

We want to find the coordinates of Parallelogram CDEF with vertices C(2, -1), D(7,1), E(6,-2), and F(1,-4) after a reflection across y = x.

We can find these coordinates by following the following rule:

Reflection over y = x rule : ( x , y ) ---> ( y , x )

the x and y values simply swap places .

Applying rule to coordinates:

C(2,-1) --- swap 2 and - 1 ---> C'(-1,2)

D(7,1) --- swap 7 and 1 ---> D'(1,7)

E(6,-2) --- swap 6 and -2 ---> E'(-2,6)

The maximum amount of revenue the carnival can expect in the town in the 5th night is; $4746.093.

A geometric progression is defined as a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

We are told that Revenue in the first night = $15000

Now revenue of new night is 75% of the previous night. Thus;

2nd night = 15000 × 75/100 = $11250

3rd night = $11250 × 75/100  = 8437.5

Therefore, the given geometric sequence is ;

15000, 11250, 8437.5 ...

First term; a = $15000

Common ratio (r) = 11250/15000 = 0.75

The formula for the nth term of a GP is given by ;

aₙ = arⁿ ⁻ ¹

Thus, revenue for the 5th night is;

a₅ = ar⁵⁻¹

a₅ = 15000(0.75)⁴

a₅ = 4746.093

We conclude that the revenue in the 5th night in two will be $4746.093.

The sum is 40,000.

The difference between compound interest and simple interest is 324 on a certain sum at 9% for 2 years.

So,

Compound interest - Simple interest = 324

C.I - SI = 324

The formula for compound interest is given as:

C.I = P( 1 + r/100 )ⁿ - P

Where P is the principal amount, r is the rate and n is the time in years.

Therefore,

C.I = P( 1 + 9/100)² - P

C.I = P( 1 + 0.09)² - P

C.I = P(1.09)² - P

C.I = 1.1881P - P

C.I = 0.1881P

Now, the formula for simple interest is given as:

S.I = ( P × R × T / 100 )

Where P is the principal amount, R is the rate and T is time in years.

Therefore,

S.I = ( P × 9 × 2 / 100 )

S.I = 18P / 100

S.I = 0.18P

Now,

C.I - S.I = 324

0.1881P - 0.18P 324

0.0081P = 324

P = 324 / 0.0081

P = 324 × 10000 / 81

P = 4 × 10000

P = 40000

The correct form of the partial fraction decomposition for the expression 7x+18/x^2+9x is  2/x + 5/(x + 9).

What is the Fraction?

Here,

x ² + 9x = x (x + 9), so the partial fraction decomposition would be

(7x + 18) / (x ² + 9x) = a/x + b/(x + 9)

where a, b are some constants. To find them, multiply both sides by x ² + 9x :

7x + 18 = a (x + 9) + bx

Solve for a and b :

7x + 18 = (a + b) x + 9a

[ a + b = 7

[ 9a = 18

→   a = 2, b = 5

So

(7x + 18) / (x ² + 9x) = 2/x + 5/(x + 9)

The equation of the line in slope-intercept form passing through the point (-7 , 10) and parallel to 2x - 3y = -3 is y = (2/3)x + 44/3.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula:

y = mx + b

where m is the slope of the line

b is the y- intercept

If the line is parallel to 2x - 3y = -3, then their slopes are equal. First, express the equation in slope-intercept form y = mx + b to get the slope, m.

2x - 3y = -3

-3y = -2x - 3

y = -2/-3 x - 3/-3

y = 2/3 x + 1

m = 2/3

Substitute the values of the slope and the point to solve for the y-intercept, b.

y = mx + b

10 = 2/3(-7) + b

b = 44/3

Write the equation of the line by plugging in the value of the slope and y-intercept.

Answer: The number 8,000 represents the change in height necessary to dodge the storm.

The integer representing the altitude after passing the storm is 30,000

Use appropriate tools, draw a number line to represent the airplanes changed altitude = 34000

Step-by-step explanation:

In the picture that is attached, the diagram for this query is displayed.

We are informed that the aircraft's starting height was 30,000 feet.

A. What integer represents the airplane's change in altitude to avoid the storm.?

During the storm:

The plane flew at at altitude of 38,000 feet

We will deduct the end altitude from the starting altitude to obtain the change in altitude.

change of altitude = final altitude - initial altitude

change of altitude = 38,000 - 30,000

                               = 8,000 ft

Therefore, the integer representing the change of altitude to avoid the storm is 8,000

B. What integer represents the airplanes change in altitude immediately after passing the storm?

After the storm:

We are aware that the aircraft returned to its original height following the storm.

The number reflecting the altitude after passing the storm would be 30,000 ft given that the starting altitude is 30,000 ft.

The answers are given below:-

The length of one side of the garage​ originally was 17.9 ft.

The length of one side of the garage​ now is 21.9 ft.

The percent increase in the length of one​ side was 22.35%.

The area of a square of side s is given by s squared, that is:

A = s².

The original area was 320 ft², hence the original length was:

s² = 320

s = √(320)

s = 17.9 ft.

The area increased by 50%, hence the new area is:

A = 1.5 x 320 = 480 ft².

The current length of one side is:

s² = 480

s = √(480)

s = 21.9 ft.

The percent increase is the change divided by the initial length and multiplied by 100%, hence:

(21.9 - 17.9)/17.9 x 100% = 22.35%.

The percent increase in the length of one​ side was 22.35%.
