Solution - Verifying Option A:

$(6^{4})^{-5} < (6^{-7}) \times (6^{-3})\\ (6^{-20}) < (6^{-7-3} )\\ 6^{-20}< 6^{-10}$

Result: True (Option A is correct)

Solution - Verifying Option B:

$(6^{4})^{-5} > (6^{-7}) \times (6^{-3})\\ (6^{-20}) > (6^{-7-3} )\\ 6^{-20}> 6^{-10}$

Result: False (Option B is incorrect)

Solution - Verifying Option C:

$(6^{4})^{-5} = (6^{-7}) \times (6^{-3})\\ (6^{-20}) = (6^{-7-3} )\\ 6^{-20}= 6^{-10}$

Result: False (Option C is incorrect)

Option A is correct.

boyakko [2]

Answer:

There are 232 students at the school.

Step-by-step explanation:

Let s represent the number of students at the school. We are told ...

174 = 75% × s

174/0.75 = s = 232 . . . . . divide by the coefficient of s

There are 232 students at the school.

Expand (4x-3y)^4 using pascal's triangle ...?

jenyasd209 [6]

Using row 4:

coefficients are: 1, 4, 6, 4, 1 

a^4 + a^3b + a^2b^2 + ab^3 + b^4 

Now adding the coefficients: 

1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + 1b^4 

Substitute a and b: 

a = 4x 

b = -3y 

1(4x)^4 + 4(4x)^3(-3y) + 6(4x)^2(-3y)^2 + 4(4x)(-3y)^3 + 1(-3y)^4 

Now simplify the above: 

256x^4 - 768x^3y + 864x^2y^2 - 432xy^3 + 81y^4

Answer:

The Graph is shown below

Step-by-step explanation:

The Graph of a Function

Given the function:

$\displaystyle y=g(x)=-\frac{3}{2}(x-2)^2$

It's required to plot the graph of g(x). Let's give x some values:

x={-2,0,2,4,6}

And calculate the values of y:

$\displaystyle y=g(-2)=-\frac{3}{2}(-2-2)^2=-\frac{3}{2}(-4)^2==-\frac{3}{2}*16=-24$

Point (-2,-24)

$\displaystyle y=g(0)=-\frac{3}{2}(0-2)^2=-\frac{3}{2}(-2)^2=-\frac{3}{2}*4=-6$

Point (0,-6)

$\displaystyle y=g(2)=-\frac{3}{2}(2-2)^2=-\frac{3}{2}(0)^2=0$

Point (2,0)

$\displaystyle y=g(4)=-\frac{3}{2}(4-2)^2=-\frac{3}{2}(2)^2=-\frac{3}{2}*4=-6$

Point (4,-6)

$\displaystyle y=g(6)=-\frac{3}{2}(6-2)^2=-\frac{3}{2}(4)^2=-\frac{3}{2}*16=-24$

Point (6,-24)

The graph is shown in the image below

A rectangle is 3 times as long as it is wide. if the area is 27 square feet, find its perimeter.

Marat540 [252]

W - a width
3w - a length
27 ft² - an area

Therefore:

w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3

3w = 3 · 3 = 9

width = 3
length = 9

The perimeter:

P = 2 · width + 2 · length

P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.
