Answer:

D. The power y Superscript 9 should be in the numerator and the power x cubed in the denominator.

Step-by-step explanation:

The correct simplification is the following:

[tex]\frac{x^{-3}}{y^{-9}} = [/tex]

[tex]= \frac{1}{x^3} \times \frac{1}{y^{-9}} =[/tex]

[tex]= \frac{1}{x^3} \times y^{9} =[/tex]

[tex]= \frac{y^{9}}{x^3}[/tex]

Which is the rate of change for the interval between 3 and 6 on the x-axis?

Step-by-step explanation:

c- 2

The 24 inch shelve is 2 feet ( 1 foot = 12 inches)

She bout 7 feet of shelves (5 + 2 = 7)

The total cost for the shelves was 7 x 1.25 = $8.75

She spend an additional 90 so her total spent was 90 + 8.75 = $98.75

Now subtract her total from 100 to find the amount of change:

100 - 98.75 = 1.25

The change was $1.25

Answer:

Lauren made her first error in step 3 because she should have used 85 minus 60 = 25 for chemistry and 80 minus 60 = 20 for biology.  

Step-by-step explanation:

Lauren's box plots may have looked like those below.

Step 1

Chemistry median = 80

Biology median      = 70

Correct.

Step 2

Difference in medians = 80 - 70

Correct

Step 3

Chemistry IQR = 85 - 60 = 25

Biology IQR     = 80 - 60 = 20

Wrong.

This is where Lauren made the mistake.

She was finding the difference between the Max and Q3.

Answer:

28 feet long together

Step-by-step explanation:

in 1 yard there is 3 feet so in 4 yards it would be 3(4) which is 12. add 12 to 16 and you get 28

Answer:

28 feet

Step-by-step explanation:

A yard is 3 feet, so

4 yards*3 feet=12 feet.

12 feet+16 feet=28 feet

Answer:

1023

Step-by-step explanation:

[tex]8^{0}[/tex] = 1, [tex]8^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{8}[/tex] = 2, [tex]8^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{8^2}[/tex] = 4, [tex]8^{1}[/tex] = 8

The series can be expressed in non exponent terms as

1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 ← 10 terms

There is a common ratio r between consecutive terms, that is

r = 2 ÷ 1 = 4 ÷ 2 = 8 ÷ 4 = .... = 2

This indicates the sequence is geometric with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]

where a is the first term and r the common ratio

Here a = 1 and r = 2, thus

[tex]S_{10}[/tex] = [tex]\frac{1(2^{10}-1) }{2-1}[/tex] = 1024 - 1 = 1023

Answer:

x = 10

Step-by-step explanation:

We see and show that  x = 10

This makes y = 5 and z = 7 as 5-7 (y-z) = -2

As y5-z7 = -2 then we add 10 = 8

x+y-z = 10x-2yz = 8

x-y+z =  10 -5  +7 = 12  we know  x = 10

We cna now prove.

x+y-z =8

x+5y-7z = 8

x +-2yz = 8

x = 8+2yz

x= 10

And prove

(x-5y)+7z= 12

x-y =12-7z

x = 5+5y

x=10

as x-5 (=5+7z) = 12

Have got the right answer here. Hope it helps.

Answer:

Division

Step-by-step explanation:

/ symbol mean division

Answer:

a) Row 5: 75 - 216 - 51

b) 3n² - (n+1)³ - (71-4n)

c) 3(n+1)² - (n+2)³ - (67-4n)

Step-by-step explanation:

Column 3:

Arithmetic sequence with common difference: 63-67 = -4

an = 67 + (n-1)(-4)

an = 67 - 4n + 4

an = 71 - 4n

Row 5: 3×5² - (5+1)³ - (71-(5×4))

Row 5: 75 - 216 - 51

Row n: 3n² - (n+1)³ - (71-4n)

Row n+1: 3(n+1)² - (n+1+1)³ - 71-4(n+1)

Row n+1: 3(n+1)² - (n+2)³ - (67-4n)

Answer:

Column 1

Tn= 3n²

row n= 3n²

row n+1= 3(n+1)²

When n=5,

T₅ = 3(5)²

T₅ = 75

Thus, row 5= 75

Column 2

Tn= (n+1)³

row n= (n+1)³

row n+1

= (n+1+1)³

= (n+2)³

When n=5,

T₅ = (5+1)³

T₅ = 6³

T₅ = 216

row 5= 216

Column 3

Notice that the terms decrease by 4 with each row.

This means that there is a common difference of -4.

Common difference formula

Tn= a +d(n-1)

where a is the first term and d is the common difference.

Tn= 67 -4(n-1)

Now, simplify the formula

Tn= 67 -4n +4

Tn= 71 -4n

Row n= 71 -4n

Row n+1

= 71 -4(n+1)

= 71 -4n -4

= 67 -4n

when n=5,

T₅= 71 -4(5)

T₅= 51

Row 5= 51

Row n is the general formula for the pattern. To find the n+1 row, susbt. n+1 into n in the formula in row n.

Answer: 19.95 x >89.95

Step-by-step explanation:

Hi, to answer this question we have to write an inequality using the information given:

The cost of each visit (x) is 19.95. That expression must be higher than the cost of the annual pass (89.95).

Mathematically speaking:

19.95 x >89.95

Answer: The volume is 3560.76 in^3   or 1134π

Step-by-step explanation:

The formula for the volume of a cylinder  is  πr^2*h

so the radius is 9 and the height is 14 so we will put that into the formula  and solve.

v=3.14 * 9^2 * 14

v= 3.14 * 81 *14

v = 3560.76 in^3  or 1134π

Answer:

Arithmetic.

Step-by-step explanation:

See if it's arithmetic:

2/3 - 1/3 = 1/3

1  - 2/3 = 1/3

4/3 - 1 = 1/3

-  common difference of 1/3 so it's arithmetic.

Answer:

9 months.

Step-by-step explanation:

Well we subtract the one time fee of $150 from $420

420-150=270

Now we need to divide $270 by $30, the price she pays every month.

270÷30=9

She has had the service for 9 months.

Answer:

No real number solutions.

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

The discriminant is b² - 4ac

• If b² - 4ac > 0 the equation has 2 real and distinct roots

• If b² - 4ac = 0 the equation has 2 real and equal roots

• If b² - 4ac < 0 the equation has no real roots

Given

2x² + 4x + 8 = 0 ← in standard form

with a = 2, b = 4 and c = 8, then

b² - 4ac = 4² - (4 × 2 × 8) = 16 - 64 = - 48 , thus

The equation has no real number solutions because the discriminant is < 0
