x=2

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

Answer:

3 1/6

Step-by-step explanation:

To find the highest value, we have to evaluate each term individually,

1)  1 1/6 = 7/6 = 1.167

2) 3 1/6 = 19/6 = 3.16

3) 3/8 = 0.375

4) 5/8 = 0.625

Therefore, second data value (3 1/6) is highest.

Answer:

Yes; there is only one range value for each domain value

Step-by-step explanation:

A relation can be defined as a function f(x) if for each value of the domain of x, there exists a unique value of f(x).

For example

(2, 4)(3, 9)(-2, 4)(4, 16) Is a Function

(2, 4)(2,6)(3, 8)(3, -8) Is Not a Function

To analyze if the relationship shown is a function, you must observe that each value of the domain has a single value of the range assigned.

For the given points {(-5, 6), (-2, 3), (3, 2), (6, 4)} this requirement is satisfied. Therefore, the relationship is a function. The graph is shown in the attached image.

The correct option is: Yes; there is only one range value for each domain value

Answer:

Yes; there is only one range value for each domain value.

Step-by-step explanation:

Let, R = {(-5, 6), (-2, 3), (3, 2), (6, 4)} is a relation,

Since, a relation is called a function if there is only one output value for each input value,

Here, the image of -5 is 6,

Image of -2 is 3,

Image of 3 is 2,

Image of 6 is 4,

That is, there is only one output value for each distinct input value,

Thus, R is a function,

Now, the input value is called domain value and output value is called range value,

Hence, SECOND OPTION is correct.

Answer:

D.

Step-by-step explanation:

A is linear, you can figure out that y=x+5

B is linear, y=22(x+1)

C is linear, y=8x+5

D is exponential, y=3ˣ⁺¹

Deriving these formulas is a matter of trial and error if you know you can choose between linear and exponential.

If your taking about question three, the answer would be B.) because an exponent added to a number is basically the number multiplied by itself by them number amount in the exponent(example: 5 to the power of 2 would be 5x5).

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]

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]

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".

Step-by-step explanation:

[tex]36 \times r = 21 \times 12 \\ 36r = 252 \\ r = 252 \div36 \\ r = 7[/tex]

The question asks to solve a proportion 36/42 = 24/r. By cross-multiplication and solving the resulting equation for r, it is found that r = 28. Therefore, the correct value of r in this instance is 28.

To solve the mathematical problem 36/42 = 24/r for the value of r, you should cross-multiply and then solve for r. Cross-multiplication means you multiply 36 by r and 42 by 24, which results in the equation 36r = 42 * 24. When you divide both sides by 36, you get r = 42 * 24 / 36 as the final form of the equation. After calculating the products and divison, you will find that r = 28.

Her weekly paycheck is 3835.82

As we know that there are 52.14 weeks in a year

Since she gets weekly check so her weekly paycheck is 3835.82

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)

Answer:

Step-by-step explanation:

It's geometric.

You are starting with -2 and multiplying each successive term by - 2

r = - 2

a1 = -2

tn = ar^(n - 1)

So to try it out, let n be the 4th term

t4 = -2 * (-2)^(4 - 1)

t4 = - 2 * (-2)^3

t4 = - 2 * -8

t4 = 16 just as the series indicated.

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

Answer:

see explanation

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)

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.
