Answer:

Simple interest is calculated on the principal, or original, amount of a loan. Compound interest is calculated on the principal amount and also on the accumulated interest of previous periods, and can thus be regarded as "interest on interest."

Step-by-step explanation:

assuming those are exponents

Answer:

9x^4 - 36x^3 - 27x^2

Step-by-step explanation:

9x(x^3 - 4x^2 - 3x)

Multiply 9x to each of the terms in the parentheses:

9x^4 - 36x^3 - 27x^2

The expenses with the given profit and revenue is $47,000. Therefore, option C is the correct answer.

Given that, the profit is $3,000 and the revenue is $50,000.

The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.

Here, Profit = Revenue - Expenses

3000 = 50000 - Expenses

⇒ Expenses = 50000-3000

= 47000

The expenses with the given profit and revenue is $47,000. Therefore, option C is the correct answer.

Answer:  1.  [tex]\frac{19}{18}=n[/tex]

               2.  x=4

Step-by-step explanation:

[tex]\frac{11}{6}-\frac{7}{9}=n[/tex] First, you have to subtract [tex]\frac{7}{9}[/tex] from both sides to have n by its self.

[tex]\frac{33}{18}-\frac{14}{18}=n[/tex] Then find the common denominator. And subtract it

[tex]\frac{19}{18}=n[/tex]

6.2-2.2=x Subtract 2.2 from both sides to have x by its self.

This can not be factored, so use the quadratic formula.

x=9±√73 /2

Answer:

x = 9 + sqrt(73) / 2

x = 9 - sqrt(73) / 2

Step-by-step explanation:

Assuming you want to factor and find its roots:

[Put all the terms in the left hand size]

x^2-9x+2=0

[Use the quadratic formula; Not factorable and too tedious for completing the square]

x = -b +- sqrt(b^2-4ac) / 2a

x = 9 + sqrt(9^2 - 4(1)(2)) / 2(1)

x = 9 - sqrt(9^2 - 4(1)(2)) / 2(1)

x = 9 + sqrt(73) / 2

x = 9 - sqrt(73) / 2

Answer:

26183

Step-by-step explanation:

Given that,

The population of the city of Gary is 75,282. 34.78% of Gary residents have a higher education degree.

We need to find the no of people in Gary have a higher education degree. It can be simply calcualted by taking 34.78% of 75,282 as follows :

[tex]P=75282\times 34.78\%\\\\ =75282\times \dfrac{34.78}{100}\\\\=26183.07[/tex]

or

P = 26183

So, there are 26183 people in Gary have a higher education degree.

Answer:

common ratio is 2/5

First term is  125/2

The sum of the first n terms is: [tex]S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{3/5}[/tex]

The infinite sum is: [tex]S_\infty =\frac{625}{6}[/tex]

Step-by-step explanation:

The 4th term is 4, and the seventh term is 32/125 so we use the definition of nth term of a geometric sequence to create the following two equations:

[tex]a_4=a_1\,*\,r^{4-1} = a_1\,*\,r^3\\4=a_1\,*\,r^3\\and\\a_7=a_1\,*\,r^{7-1} = a_1\,*\,r^6\\\frac{32}{125} = a_1\,*\,r^6[/tex]

Now we divide a7 by a4 to get rid of a1 and work on determining the common ratio of the sequence:

[tex]\frac{a_7}{a_4} =\frac{8}{125} =\frac{a_1\,r^6}{a_1\,r^3} =r^3\\then\\r=\sqrt[3]{\frac{8}{125} } =\frac{2}{5}[/tex]

So, the common ratio is 2/5

we can now determine the first term:

[tex]a_4=4=a_1\,*\,(2/5)^3\\a_1=\frac{125*4}{8} =\frac{125}{2}[/tex]

The sum of the first n terms is given by the formula:

[tex]S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{1-(2/5)} \\S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{3/5}[/tex]

and therefore, the infinite sum is:

[tex]S_\infty = a_1\,\frac{1}{1-r} = \frac{125}{2} \,\frac{5}{3} =\frac{625}{6}[/tex]

Answer:

0

Step-by-step explanation:

We can find the slope using

m = ( y2-y1)/(x2-x1)  where ( x1,y1) and ( x2,y2) are points on the line

m = ( -2 - -2)/(8 - 2)

    = ( -2 +2) / ( 8-2)

    = 0/6

   =0

The slope is 0

Step-by-step explanation:

Part A

-2 -2+7=y y= +5 y=5

-1 -1+7=y y= 6

0 0+7=y y= 7

1 1+7=y y=8

2 2+7=y y=9

Answer:

Option 3: 14 is the correct answer.

Step-by-step explanation:

Slope is denoted by m and is calculated using the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

(x1,y1) are the coordinates of first point and

(x2,y2) are the coordinates of second point

Given

(x1,y1) = (3, -20) and

(x2,y2) = (5,8)

Putting the values in the formula, we get

[tex]m = \frac{8-(-20)}{5-3}\\m = \frac{8+20}{2}\\m = \frac{28}{2}\\m = 14[/tex]

The slope of line passing through points (3, -20) and (5,8) is 14.

Hence,

Option 3: 14 is the correct answer.

Answer:

Lower

Step-by-step explanation:

Use the number 100 to see how the value changes:

First, calculate the 60% drop:

100(0.4)

= 40

Then, calculate the 75% increase:

40(1.75)

= 70

So, since 70 is smaller than 100, the value is lower than where it started.

Answer:

m < 2 = 36

m < 3 = 148

Step-by-step explanation:

180 - 148 = 32

The measure of <2=32 and <3=148

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

Given:

m<5 = 148

As, by alternate interior angle

m<5 = m<3

So, m<3 = 148

Also, <2 and <3 forms a linear pair.

So,

m<2 + M<3 = 180

148 + m<2 = 180

m<2 = 32

Hence, the measure of <2 = 32 and <3 = 148.
