PLEASE HELP!!Select the expressions that are equivalent to 3/4x^3 . Select all that apply.

Answer:

2)    (1,1.5)

4) Not enough information

Step-by-step explanation:

2) If you look along at the intersection point of the two lines it's (1,1.5).

4) Since only one equation is graphed, we can't tell anything.

The value of the equation A = 837.2 / 1.3 is A = 644

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be p

The value of p = 837.2

Let the second number be q

The value of q = 1.3

Now , the equation A = p/q

Substituting the values in the equation , we get

A = 837.2 / 1.3

On simplifying the equation , we get

A = 644

Therefore , the value of A is 644

Hence , the equation is A = 644

Step-by-step explanation:

The estimated length of a paperback book is "8 inches".

The paperback also called a paperback or softback, is a sort of book with a thick paper or paperboard cover that is often held together along with glue rather than stitches or staples.

Hardcover or hardcover books, but at the other extreme, are bonded with cardboard covered in linen, plastic, or leather.

Since 4 inches is far too short, and "14 and 18 " inches is longer than a ruler.

Therefore, the answer is "8 inches".

Answer:

(a - 7)(3 - x)

Step-by-step explanation:

Given

3(a - 7) - x(a - 7) ← factor out (a - 7) from both terms

= (a - 7)(3 - x)

Present age of Selma = s

Present age of Joyce = j

Selma is now 3 times as old as joyce

s=3j........(1)

Four years ago,

s-4=j-4

then

Selma was 4 times as old as joyce

s-4=4(j-4)

s-4=4j-16

s=4j-16+4

s=4j-12.............(2)

Put the value of s in (2) from (1)

3j=4j-12

3j-4j=-12

-j=-12

Multiply by -1 both sides

j=12

Put the value of j in (1)

s=3j

s=3(12)

s=36

Present age of Selma = s = 36 years old

Present age of Joyce = j = 12 years old

Answer:

The discount is $109.50

The sale price is $255.50

Step-by-step explanation:

step 1

Find the discount

we know that

The discount is equal to the original price multiplied by the percentage rate of discount

we have

The original price is $365

The percentage of discount is equal to 30%

30%=30/100=0.30

so

the discount is equal to

0.30*($365)=$109.50

step 2

Find the sale price

The sale price is equal to the original price minus the discount

so

$365-$109.50=$255.50

Step-by-step explanation:

(a)

Consider the factors of the coefficient of the y² term ( - 12) which sum to give the coefficient of the xy- term (- 4)

The factors are - 6 and + 2

since - 6 × 2 = - 12 and - 6 + 2 = - 4, hence

x² - 4xy - 12y² = (x - 6y)(x + 2y)

----------------------------------------------------

(b)

Consider the factors of + 12 which sum to give + 8

The factors are + 2 and + 6, hence

x² + 8x + 12 = (x + 2)(x + 6)

Answer:

a = 9.632  and b is 10

9.632*10^10 in^3  scientific form

96,320,000,000   in^3  standard form

Step-by-step explanation:

To find volume of a rectangular prism

V = l*w*h

   = 1.4 * 10^4   ( 4.3 * 10^3)   (1.6* 10^3)

When multiply powers of 10, we multiply the numbers out front

1.4*4.3*1.6 =9.632

Then we add the powers of 10

10^(4+3+3)

10^10

The volume is 9.632*10^10 in^3

a = 9.632  and b is 10

In standard form we move the decimal 10 places to the right.  If there are not enough numbers we add zeros

9.632*10^10 in^3

96,320,000,000   in^3

200,000/52 weeks in a year =$3846.153846 each week

Step-by-step explanation:

The sum to infinity of a geometric series is

[tex]\frac{a_{1} }{1-r}[/tex] ( - 1 < r < 1 ) ← substitute values

S( ∞ ) = [tex]\frac{5}{1-\frac{1}{3} }[/tex] = [tex]\frac{5}{\frac{2}{3} }[/tex] = [tex]\frac{15}{2}[/tex]

The sum of the infinite geometric series is [tex]\frac{15}{2}[/tex]

The sum of all the terms of a geometric sequence is called infinite geometric series.

If a, ar, a[tex]r^{2}[/tex], ...., a[tex]r^{n-1}[/tex], .... is a geometric series, then  a+ar+a[tex]r^{2}[/tex]+ ....+a[tex]r^{n-1}[/tex]+.... is the corresponding infinite geometric series.

where a is the 1st term & r is the common ratio between consecutive terms of the series.

Sum of infinite geometric series = [tex]\frac{a}{1-r}[/tex] ; |r|<1

Given, 1st term ([tex]a_{1}[/tex]) of the infinite geometric series = 5

Common ratio (r) = 1/3

∴ Sum of infinite geometric series = [tex]\frac{a_{1} }{1-r}[/tex]

                                                         = [tex]\frac{5}{1-\frac{1}{3} }[/tex]

                                                         = [tex]\frac{5}{\frac{2}{3} }[/tex]

                                                         = [tex]\frac{15}{2}[/tex]

General Solution

Left hand side

tan(30) + 1 / tan(30

tan^2(30) + 1

============

tan 30

but tan^2(30) + 1 = sec^2(30)

sec^2(theta) / tan(30) Let theta = 30o. This will work for any angle between 0 and 90

[tex]\dfrac{sec^2(theta)}{tan(theta)} = \dfrac{sec^2(theta)}{\dfrac{sin(theta)}{cos(theta)}} = \dfrac{1}{\dfrac{cos^2(theta)*sin(theta)}{cos(theta)}}[/tex]

Cancel out cos(theta) and one of cos^2(theta)

leaving your with

[tex]\dfrac{1}{sin(theta)*cos(theta)}[/tex]

which is exactly what the right hand side is.

This is the way this problem should be done. If you want to show what happens with 30o then

Thirty degree angle

tan(30) = 0.5774

Left hand side

0.5774 + 1/(0.5774) = 2.3093

Right hand side

1/(sin(30)*cos(30))

1/(0.5 * 0.8660)

1/(0.4330

2.3094

Which is about as close as you will get when you round.

Answer:

= -7

Step-by-step explanation:

6 ⁹ ×6^x = 6²

From the laws of indices;

aⁿ × aⁿ = a^2n

Therefore;

6 ⁹ ×6^x = 6^(9+x)

6^(9+x) = 6²,

Since the bases are the same then the exponents are equal;

9+x = 2

x = -7

Answer:

x=-7

Step-by-step explanation:

[tex]6^9 \cdot 6^x = 6^2[/tex]

Apply exponential property to solve for x

[tex]a^m \cdot a^n = a^{m+n}[/tex]

[tex]6^9 \cdot 6^x = 6^{9+x}[/tex]

So the given equation becomes

[tex]6^{9+x}= 6^2[/tex]

Both sides of the equation has same base 6

So we equate the exponent and solve for x

[tex]9+x= 2[/tex]

Subtract 9 from both sides

[tex]x=-7[/tex]

Answer:

y = 9x - 5

Step-by-step explanation:

Any line parallel to the given line y = 9x must also have the slope 9.

Substitute the known values (m = 9, h = 0, k = -5) into the point-slope equation of a straight line:

y - (-5) = 9(x - 0)

Then y + 5 = 9x, or

         y = 9x - 5

Answer:

Step-by-step explanation:

the fraction is boys over total in class, that is

fraction of boys = [tex]\frac{8}{24}[/tex] ( divide top/bottom by 8 )

fraction of boys = [tex]\frac{1}{3}[/tex] ← in simplest form

(b)

The number of girls in class = 24 - 8 = 16

fraction of girls = [tex]\frac{16}{24}[/tex] ( divide top/bottom by 8 )

fraction of girls = [tex]\frac{2}{3}[/tex] ← in simplest form

The number of boys is 1/3

The number of girls is 2/3

Total no of students = 24

No of boys in the class is 8

So in fraction form

Boys = 8 out of 24 which is 8/24 or simply 1/3

Now

For girls

no of girls will be Total students - boys students

Number of girls students = 24 - 8 = 16

In fraction form we can write 16/24 or simply 2/3
