The value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x and the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.
First, let us know some laws of exponent:
(a²) · (a³) = a²⁺³ = a⁵(a²)³ = a²ˣ³ = a⁶(a²) ÷ (a³) = a²⁻³ = a⁻¹We are given;
[tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] and [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex].
Now, we will solve one by one;
[tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex]
[tex]= \sqrt[5]{\frac{2^{10}(x^{-10})}{(2^5x^{-15})}}[/tex]
[tex]=[({2^{10}. 2^{-5}) (x^{-10}.x^{15})}]^\frac{1}{5}[/tex]
[tex]=[({2^{10-5}) (x^{-10+15})]^\frac{1}{5}[/tex]
[tex]=[({2^{5}) (x^{5})]^\frac{1}{5}[/tex]
= 2x
So, the value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x.
Now,
[tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex]
[tex]=\frac{(2^3x^6y^{-3})^\frac{1}{3} }{(2^3x^3y^3)}[/tex]
[tex]=\frac{(2x^26y^{-1})}{(2^3x^3y^3)}[/tex]
[tex]=\frac{1}{(2^{3-1}x^{3-2}y^{3+1})}[/tex]
[tex]=\frac{1}{(2^{2}x^{1}y^{4})}[/tex]
= 1 / 4xy^4
So, the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.
Thus, the value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x and the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.

Find tα/2 for n = 18 and a 99% confidence interval.
Answers
The value of tα/2 of the t-test is 2.898
How to determine tα/2?A t-test is a statistical test that is used to compare the means of two groups. tα/2 refers to the t critical value from the t-distribution table that corresponds to α/2
Given: n = 18 and a 99% confidence interval
We have to find the critical t value for 99% confidence level and sample size of 18
Degrees of freedom = n - 1 = 17
α = 1 - 0.99 = 0.01
α/2 = 0.01/2 = 0.005
In the t table (check the attached image), we have to check the value against the column 0.005 and for 17 degrees of freedom.
The value obtained from the table is 2.898

The revenue for a business, as a function of units produced, x, is shown below
by R(x). C(x) represents the cost of producing x units. Calculate the profit function and then determine how many units must be produced for the business to break even.
R(x) = 12x
C(x) = x + 264
Answers
Profit function = P(x) = 11x - 264 and 24 Units must be produced for the business to break even.
What is a Profit function?
A mathematical link between a company's overall profit and output is called a profit function. It is greatest when the firm's marginal revenue and cost are equal. It is equal to total revenue minus total costs.
How to calculate the profit function?
Profit function = Revenue function - Cost function
P(x) = R(x) - C(x)
Here, we have
R(x) = 12x
C(x) = x + 264
by applying the Profit function formula, we get
P(x) = 12x - x - 264
P(x) = 11x - 264
At this point, there is no profit or loss.
so, at break-even P(x) = 0
11x - 264 = 0
x = 24
Hence, Profit function = P(x) = 11x - 264, and 24 Units must be produced for the business to break even.

Hey can someone please find the area of this shape? Thank you so much I’ll give brainly. Please explain
Answers
Answer:
44.63
Step-by-step explanation:
( The heart shape makes two half circles and a square )
1 ) The two half circles together make a whole, so we can first find the area of that circle!
2 ) We can see that the dynamiter is 5in. We can cut this in half to find the radius...
5 ÷ 2 = 2.5
3 ) The area of a circle is found with the equation ( A = πr2 ). We can plug in the radius ( 2.5 ) to find the area...
A = π( 2.5 )2 = 19.635in
4 ) Now that we know the area of the circle we can find the area of the square. To find this we can use the equation ( A = a2 ) where a represents the edge length in this case 5in.
A = ( 5 ) 2 = 25in
5 ) We can now add the area of the circle and the area of the square to get the area of the heart!
19.635 + 25 = 44.63

I NEED THIS ASAP
Answers
Answer:
Graph 1: y = (-3x/5) + 1
Graph 2: y = 4
Step-by-step explanation:
Both functions are linear, so we can use a linear equation to model these functions. Using slope-intercept form, "y=mx+b" will be easiest, since the graph is shown.
Graph 1:
(1 - (-2))/(0 - 5) = (1 + 2)/-5 = -3/5 = slope
y-intercept (0, 1)
y = (-3x/5) + 1
Graph 2:
(4 - 4)/(1 - 0) = 0 = slope
y-intercept (0, 4)
y = 0x + 4
y = 4
Answer:
First equation : [tex]y=-\frac{3}{5}x +1[/tex]
Second equation : y = 4
Step-by-step explanation:
We want to write equations for the two given lines in slope intercept form
y = mx + b
Where m = slope and b = y intercept
Identifying the y intercept
First lets find the y intercept.
The y intercepts is where the line passes the y axis.
By looking at the first line it appears that the line passes the y axis at (0,1) meaning the y intercept is 1 so b = 1
Identifying the slope
We can find the slope using the slope formula
slope = (y1-y2)/(x1-x2)
Where the values of x and y derive from any two points on the line. (x1,y1) and (x2,y2)
The points used may vary as there are many options however I have chosen (0,1) and (-5,4)
So (x1,y1) = (0,1) and (x2,y2) = (-5,4)
Meaning x1 = 0 , y1 = 1 , x2 = -5 and y2 = 4
( we now plug these into the slope formula )
Again recall slope = (y1-y2)/(x1-x2)
==> plug in x1 = 0 , y1 = 1 , x2 = -5 and y2 = 4
slope = (1-4)/(0-(-5))
==> reduce subtraction
slope = -3/5
so our slope(m) is -3/5
Plugging in slope and y intercept into slope intercept form
Finally we plug in the values of m and b into slope intercept form to get the equation
Again we have y = mx + b
m = -3/5 and b = 1
So our equation is y = -3/5x + 1
Identifying equation for second line
When we have a horizontal line our equation is going to be put in y = b form where b = the y value that the line crosses. (or y intercept)
Here the line goes through the y value of 4 so b = 4
Hence, the equation of the second line would be y = 4
Which expression is equivalent to 8 ^ -3
Answers
The expression 1 / 8^3 is equivalent to 8^-3. Option B is correct.
First, let us understand the exponents or power:
A power, or index, is a little floating number that appears next to a number or letter.
It is denoted as a^m.
where a = base number
and m = power or index number.
Some laws of exponents are:
(a²) · (a³) = a²⁺³ = a⁵(a²)³ = a²ˣ³ = a⁶(a²) ÷ (a³) = a²⁻³ = a⁻¹a⁻¹ = 1 / aWe are given:
8^-3
We can solve as;
8^-3 = 8^(3 * -1) = (8^3) ^ -1 = 1 / 8^3 [since a⁻¹ = 1 / a]
So, 8^-3 = 1 / 8^3.
Thus, the expression 1 / 8^3 is equivalent to 8^-3. Option B is correct.

Humberto's displacement is 2 miles due south far from his starting point.
How is the displacement completed?We understand that displacement is a vector quantity with both magnitude and direction, while distance is a scalar quantity with only magnitude.
Displacement, unlike distance, shows the direction and position of an object from its original base. This means that displacement refers to how far an object has traveled out of its original position with the direction included.
In other words, displacement shows the object's overall change in position and the direction of the new position from the former.

Answers
Answer:
A: 25,500
B: 14,600
C: 10,900
Step-by-step explanation:
This is what we know:
a = b + c
a + b + c = 51,000 Substitute in a for b + c
a + a = 51000 Combine like terms.
2a = 51000 Divide both sides by 2
a = 25,500
28a + 16b + 12c = 1078400 Substitute in 25.600 for a
28(25500) + 16b + 12c = 1078400
714000 + 16b + 12c = 1078400 Subtract 714000 from both sides
16b + 12 c = 364400
25500 +b + c = 51000 Subtract 25500 from both sides
b + c + = 25500 Multiply this equation all the way through by -12 and add it to the bold equation above it.
-12b -12c = -306000
16b + 12c = 364400
4b = 58400 divide both sides by 4
b = 14600
a + b + c = 51000 Plug in what we know
25500 + 14600 + c = 51000
40100 + c = 51000 Subtract 40100 from both sides
c = 10900
