The smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.
Given, a function
y = 1/2(x² - 8)
We have to find the smallest distance between origin and a point on the graph of y = 1/2(x² - 8).
Now, the point on the graph be,
( x , 1/2(x² - 8) ) and origin be (0 , 0)
Let the function of the distance between both the points be,
D = √(x - 0)² + (1/2(x² - 8) - 0)²
D = √x² + 1/4(x² - 8)²
D² = x² + 1/4(x² - 8)²
On differentiating, we get
2DD' = 2x + x(x² - 8)
x³ + 2x - 8x = 0
x³ - 6x = 0
x(x² - 6) = 0
So, x = 0 , √6 , -√6
and the distance is minimum for x = √6
Therefore, using distance formula, we get
Distance = √(x1 - x2)² + (y1 - y2)²
Distance = √(0 - √6)² + (0 - (-1))²
Distance = √6 + 1
So, the smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.
Hence, the smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.

t is the solution to the linear equation?
x – StartFraction 2 Over 3 EndFraction x minus StartFraction one-half EndFraction equals StartFraction 1 Over 3 EndFraction plus StartFraction 5 Over 6 EndFraction x. = + x
The solution for the linear equation:
x - (2/3)*x - (1/2) = (1/3) + (5/6)*x
Is x = -5/3
How to solve the linear equation?Is hard to understand what you wanted to write, but I assume that the linear equation that we need to solve is:
x - (2/3)*x - (1/2) = (1/3) + (5/6)*x
To solve this linear equation, we need to isolate the variable x in one of the sides of the equation
To do so, we move all the terms with "x" to the left side and the terms without to the right side:
x - (2/3)*x - (5/6)*x = 1/3 + 1/2
Now we solve this:
x - (4/6)x - (5/6)x = 2/6 + 3/6
x - (9/6)*x = 5/6
We can write the "1" in the first term as 6/6
(6/6)*x - (9/6)*x = 5/6
(-3/6)*x = 5/6
-3x = 5
x = 5/-3
x = -5/3
That is the solution of the linear equation.

Step-by-step explanation:
The black graph is the graph of
= f(x). Choose the equation for the
red graph.
a.
y = f(2x)
b. y=f(2)
C.
2y = f(x)
d.
½ = f(x)
Enter
The equation for the red graph is y = f(x/2).
We are given a graph. The graph shows two functions. A function connects an input to an output. It is similar to a machine with input and output. And the result is somehow connected to the input in some way. One of the functions is depicted by black lines. We need to find the equation of the function represented by the red lines.
We can see that the function represented by the red lines can be formed if the black lines are stretched horizontally. The black lines can be stretched horizontally by a factor of 2 to form the red lines. A function y = f(x) can be stretched horizontally by a factor of "k" as given below.
y = f(x/k)
Hence, the equation for the red graph is y = f(x/2).

What are inequality equations in algebra ?
When you first begin learning algebra, the equals sign is used to denote that two items are, in fact, equal to one another. As an illustration, consider the equations 3 = 3, 5 = 3 + 2, apple = apple, pear = pear, etc. When compared, an inequality reveals two things: first, that the objects being compared are not equal, or at the very least, they are not always equal; and second, how they are uneven.
Consider the provided inequality.
5x + 1/3(3x+6) > 14
Distributive property:
a (b +c)= ab + ac
By the distributive property.
5x + 1/3 * 3x + 1/3 * 6 > 14
5x + x + 2 > 14
Add the like terms
6x + 2 > 14
Subtract 2 from both sides.
6x > 12
Divide both sides by 6.
6x/6 > 12/6
x > 2
Hence, value of x for the given inequality equation will be greater than 2 i.e, x > 2.

A survey of 25 people was conducted to determine their favorite color. 13 people like Red, 8 people like blue and 13 people like yellow. 5 people like both Red & Blue, 4 people like both Blue & yellow, 7 people like both Red & yellow and 2 people like all three colors.
Question: How many did not like any of the three colors?
The number of people who do not like any of the three colour is 5, using the set theory.
What is Set theory?
A subfield of mathematics called set theory studies sets and their characteristics. Set theory's fundamental ideas are straightforward and seem to stand on their own. The set theory appears to be straightforward, but it is actually a very complex topic. Mathematicians have specifically demonstrated how almost all mathematical ideas and conclusions may be formalized within the theory of sets. This is regarded as one of the pinnacles of contemporary mathematics. Given this accomplishment, it is possible to assert that set theory serves as the foundation for mathematics.
In the given question, we have:
Total number of people in the survey = 25;
Number of people like red = 13;
The number of people who like blue = 8;
The number of people who like yellow = 13;
5 people like both Red & Blue,
4 people like both Blue & yellow,
7 people like both Red & Yellow
2 people like all three colors.
Let n be the number of people who do not like any of the three colour.
Using the concept of set theory, we can write it as:
3 + 4 + 1 + 5 + 2 + 3 + 2 + n = 25;
⇒20 + n = 25;
n = 25 - 20
n = 5;

Write equations for a pair of perpendicular lines that intersect at the point at (-3, -7)
Equation for the given pair of lines which are perpendicular to each other and intersect at the point (-3 , -7 ) are :
( y + 7 ) = m₁ ( x + 3) and ( y + 7 ) = (-1 / m₁ )( x + 3 )
As given in the question,
Pair of equations that are perpendicular to each other and intersect at point ( -3 , -7 ) are as follow:
let us consider slope of perpendicular lines are m₁ and m₂.
Product of the slope of perpendicular lines = -1
⇒ m₁ × m₂ = -1
⇒ m₂ = -1 / m₁
Pair of perpendicular intersect at point ( -3 , -7 ) .
Required equation of perpendicular lines is given by :
For line 1:
( y - (-7)) / ( x - (-3) ) = m₁
⇒ y + 7 = m₁ (x+3)
For line 2:
( y - (-7)) / ( x - (-3) ) = m₂
⇒ y + 7 = m₂( x+ 3)
⇒ y + 7 = -1 / m₁ ( x+ 3)
Therefore, equation for the given pair of lines which are perpendicular to each other and intersect at the point (-3 , -7 ) are :
( y + 7 ) = m₁ ( x + 3) and ( y + 7 ) = (-1 / m₁ )( x + 3 )

The answer for no 7 is A. 24 in, for no 8 is C. 10 in, for no 9 is D. similar
Step-by-step explanation:
The answer for no 7 can be calculation as follows
Since both rectangles are similar, then the corresponding side are proportional, and it follows
[tex]\frac{\overline{KJ}}{\overline{AB}}=\frac{x}{\overline{AD}}[/tex]
[tex]\frac{48}{144}=\frac{x}{72}[/tex]
Where [tex]x[/tex] is the line segment [tex]\overline{MJ}[/tex]
Multiply both sides by [tex]72[/tex] to isolate [tex]x[/tex]
[tex]\frac{48}{144}\times 72=\frac{x}{72}\times 72[/tex]
[tex]\frac{48\times 72}{144}=x[/tex]
[tex]\frac{3456}{144}=x[/tex]
[tex]24=x[/tex]
Since the value of [tex]x[/tex] is [tex]24[/tex], then the length of [tex]\overline{MJ}[/tex] is [tex]24[/tex] in
The answer for no 8 can be calculation as follows
Since both rectangular frames are similar, then the corresponding side are proportional, and it follows
[tex]\frac{w_2}{w_1}=\frac{x}{h_1}[/tex]
Where [tex]w_2[/tex] is the width of frame [tex]2[/tex], [tex]w_1[/tex] is the width of frame [tex]1[/tex], [tex]x[/tex] is the height of frame [tex]2[/tex], [tex]h_1[/tex] is the height of frame 1
Substitute [tex]8[/tex] for [tex]w_2[/tex], [tex]12[/tex] for [tex]w_1[/tex], [tex]15[/tex] for [tex]h_1[/tex]
[tex]\frac{8}{12}=\frac{x}{15}[/tex]
Multiply both sides by [tex]15[/tex] to isolate [tex]x[/tex]
[tex]\frac{8}{12}\times 15=\frac{x}{15}\times 15[/tex]
[tex]\frac{8\times 15}{12}=x[/tex]
[tex]\frac{120}{12}=x[/tex]
[tex]10=x[/tex]
Since the value of [tex]x[/tex] is [tex]10[/tex], then the height of the second rectangular frame is [tex]10[/tex] in

Step-by-step explanation:
Ratio:
Find the quantity of yellow and red dye in the mixture.
Yellow : Red = 9 : 2
Total share = 9 + 2 = 11
[tex]\sf \text{Quantiy of yellow} = \dfrac{9}{11}*44[/tex]

The equations that represent the circle having a diameter of 12 units and a center lying on y-axis are; x² + (y – 3)² = 36, and x² + (y + 8)² = 36.
What is the standard form of the equation of a circle?The standard form of the equation of a circle is (x - h)² + (y - k)² + r², where (h, k) is the center of the circle, and r is its radius.
We have given that circle having a diameter of 12 units, will have a radius of 12/2 = 6 units. Thus, r = 6.
Since we know that circle having the center on the y-axis will have a center as (0, k) as all points on the y-axis have x-coordinate 0.
Thus, the equation of the circle, with a diameter of 12 units is;
x² + (y - k)² = 6², or,
x² + (y - k)² = 36.
From the given options, the equations x² + (y – 3)² = 36, and x² + (y + 8)² = 36, are correct.
Thus, the equations that represent the circle having a diameter of 12 units and a center lying on y-axis are; x² + (y – 3)² = 36, and x² + (y + 8)² = 36.
