The equation of y as a function of x is y = 1/2(x)^1/5
How to express y as a function of x?The equation is given as:
x - 32y^5 = 0
Rewrite the equation as
32y^5 = x
Divide both sides by 32
y^5 = 1/32x
Take the 5th root of both sides
y = 1/2(x)^1/5
Hence, the equation of y as a function of x is y = 1/2(x)^1/5

The conclusion might be accurate or inaccurate.
The conclusion could be true or false if an argument has some true premises and some false premises and is valid. You only know that the premises cannot both be true and the conclusion must be false because the argument is sound. But the incorrect premises already rule out the possibility of possessing this set of truth values (that is, you cannot have all true premises). As a result, the argument's validity is unaffected whether the conclusion is true or untrue. As a result, the conclusion of an argument that contains only false premises may or may not be true.
Can an argument have all true premises and a false conclusion?TRUE. A valid argument cannot, by definition, have a false conclusion and all true premises.
Therefore, a valid argument must have an erroneous premise if it has a false conclusion.

Solve two thirds times v plus 6 equals one third times v minus 2.
v equals negative eight thirds
v equals eight thirds
v = −24
v = 24
The value of v using the equation ( 2v/3 ) + 6 = ( v/3 ) - 2 is v = - 24.
Two-thirds of anything is an amount that is two out of three equal parts of it. Similarly, one-third of something is an amount that is one out of three equal parts of it.
Now, we have
Two-thirds times v plus 6 equals one-third times v minus 2.
Hence, when the above statement is expressed as an equation we get:
Two third of v + 6 = one third of v - 2
2/3 × v + 6 = 1/3 × v - 2
( 2v/3 ) + 6 = ( v/3 ) - 2
Adding 2 on both sides of the equation,
( 2v/3 ) + 6 + 2 = ( v/3 ) - 2 + 2
( 2v/3 ) + 8 = ( v/3 )
Subtracting 2v/3 from both sides of the equation,
2v/3 + 8 - 2v/3 = v/3 - 2v/3
8 = ( v - 2v )/3
- v/3 = 8/1
By cross multiplication,
- v × 1 = 8 × 3
- v = 24

Robert is preheating his oven before using it to bake. The initial temperature of the oven is 65° and the temperature will increase at a rate of 25° per minute after being turned on. What is the temperature of the oven 10 minutes after being turned on? What is the temperature of the oven t minutes after being turned on?
The temperature of the oven 10 minutes after being turned on will be 315°.
The temperature of the oven t minutes after being turned on will be 65 + 25t
How to compute the value?The temperature of the oven 10 minutes after being turned on will be:
= 65 + (25 × t)
where t = number of minute
= 65 + (25t)
= 65 + 25(10)

N
The value of x is equal to 8 and the values of AN and NB are 10 and 15 respectively.
The three points A, N and B are collinear, and N is between A and B. Collinear points are defined as set of those points which lie on the same line when plotted.
If A, N and B are collinear then,
AB = AN + NB
According to question, AB = 25, AN = 2x-6 and NB = x+7 thus,
25 = 2x-6 + x+7
25 = 3x + 1
24 = 3x
=> x = 24/3
=> x = 8
Now, AN = 2x-6 = 16-6 = 10
NB = x+7 = 8+7 = 15

a line passes through the points (4, 13) and (2, 5). What is it’s equation in slope intercept form
Answer:
y = 4 x - 3
Step-by-step explanation:
Find the equation of the line in slope-intercept form with the properties:
point: p_1 = (4, 13)
point: p_2 = (2, 5)
The slope of the line through points (x_1, y_1) and (x_2, y_2) is m = (y_2 - y_1)/(x_2 - x_1):
m = (5 - 13)/(2 - 4) = (-8)/(-2) = 4
Substitute the slope m = 4 and point (x_1, y_1) = (4, 13) into the point-slope equation y - y_1 = m (x - x_1):
y - 13 = 4 (x - 4)
Add 13 to both sides:
y = 13 + 4 (x - 4)
Distribute: 4 (x - 4) = 4 x - 16:
Answer: y = 4 x - 3

Triangle 1: 5,x-4,x-5
Triangle 2: 10,16,x-10
The equation is 5 + x - 4 + x - 5 = 10 + 16 + x - 10 and on solving the value of x is 20
The perimeter of a triangle is calculated by the summation of all the sides of a triangle
It is given that both the triangles have the same perimeter, so summation of all the sides of one triangle is equal to summation of all the sides of another triangle
Therefore the equation can be 5 + x - 4 + x - 5 = 10 + 16 + x - 10
Further solving the equation to calculate the unknown variable x
5 + x - 4 + x - 5 = 10 + 16 + x - 10
2x - 4 = x + 16
2x - x = 16 + 4
x = 20

a line segment has (x1, y1) as one endpoint and (xm, ym) as its midpoint. find the other endpoint (x2, y2) of the line segment in terms of x1, y1, xm, and ym. use the result to find the coordinates of the endpoint (x2, y2) of each line segment with the given endpoint (x1, y1) and endpoint (xm, ym).
The coordinates are:
For the first line, coordinates are (3, 7).For the second line, the coordinates are (12, 0).What are coordinates?A coordinate system in geometry is a system that uses one or more numbers, or coordinates, to determine the position of points or other geometric elements on a manifold such as Euclidean space.To find the coordinates:
In Analytical Geometry, the midpoint of a line is calculated as the mean of two points, as follows:
[tex]$$x_m=\frac{x_1+x_2}{2}, y_m=\frac{y_1+y_2}{2}$$[/tex]
Each segment has two endpoints and two midpoints, which are as follows:
(1,-9), as well as its midpoint (2,-1)(-2,18), as well as its midpoint (5,9)We must be cautious not to add the wrong coordinates.
In the first line A:
[tex]$$\begin{aligned}&2=\frac{1+x_2}{2} \\&4=1+x_2 \\&4-1=-1+1+x_2 \\&x_2=3 \\&-1=\frac{y_2-9}{2} \\&-2=y_2-9 \\&+2-2=y_2-9+2 \\&y_2=-7\end{aligned}$$[/tex]
So (3,7) is the other endpoint where the segment begins (1,-9).
The endpoint of the second line b at (-2,18) and its midpoint (5,9).
[tex]$$\begin{aligned}&5=\frac{-2+x_2}{2} \\&10=-2+x_2 \\&+2+10=+2-2+x_2 \\&x_2=12 \\&9=\frac{18+y_2}{2} \\&18=18+y_2 \\&-18+18=-18+18+y_2 \\&y_2=0\end{aligned}$$[/tex]
So, (12,0) is the opposite endpoint.
Therefore, the coordinates are:
For the first line, coordinates are (3, 7).For the second line, the coordinates are (12, 0).Know more about coordinates here:

one diagonal of a rhombus has endpoints (-10, 1) and (2, 9). what are the endpoints of the other diagonal?
The endpoints of the other diagonal are (-2, 2) and (-6, 8).
Distance formula, Algebraic expression that gives the distances between pairs of points in terms of their coordinates (see coordinate system). In two- and three-dimensional Euclidean space, the distance formulas for points in rectangular coordinates are based on the Pythagorean theorem.
Given we have a rhombus with endpoints (-10, 1) and (2, 9)
So as we already know, a rhombus is a parallelogram whose sides are equal, so the distance from say (-10, 1) to either endpoint of the other diagonal must be the same.
Distance between 2 points [tex]$\mathrm{d}=\sqrt{[-2-(-10)]^2+[2-1]^2} \Longrightarrow d=\sqrt{(-2+10)^2+(2-1)^2}$$\mathbf{d}=\sqrt{\mathbf{6 4 + 1}} \Longrightarrow d=\sqrt{65}$[/tex]
While solving with other coordinate we get [tex]$\mathbf{d}=\sqrt{(-6+10)^2+(8-1)^2}[/tex]
[tex]$\mathrm{d}=\sqrt{16+49}\\\Longrightarrow d=\sqrt{65}$[/tex]

The total number of registered doctors are estimated as 236,995.
What is meant by percentage?A percentage is a relative value that represents the hundredth part of any quantity. One percent (symbolized 1%) is one hundredth part; thus, 100 percent signifies the entire amount and 200 percent specifies twice this same given amount.
The concept of cumulative percentage (percentile) is widely used in statistics. For example, a student who achieves the 83rd percentile on an investigation has outperformed 83 percent of the students with and who a comparison is made. The likelihood of an event occurring can be expressed as a percentage. (or fraction).Now, as per the given question;
It says, from all the registered doctors 17.3% is female doctors.
Now, let use assume that the total number of registered doctors be 'x'.
Then, 17.3% of this x will give 41,000 female doctors.
So, the equation will form as;
17.3% of x = 41,000
Or, (17.3×x)/100 = 41,000
x = (41,000×100)/17.3
x = 236,994.21
x = 236995 (nearest whole number)
