If triangle OPQ is dilated about the center of the triangle to create triangle O'P'Q', what can you
conclude about segments RS and R'S'? (6 points)
Segment O'Q' is perpendicular to segment R'S'.
Line RS is parallel to line R'S'.
Line RS is perpendicular to line R'S:
Point P' passes through line RS.
Dilation is a type of transformation. So it can concluded that: Line RS is parallel to line R'S'.
Transformation is a method required to either increase or decrease the size of a given object, or change its orientation. Types of transformation are dilation, translation, rotation and reflection.
Dilation is a process in which the size of a given shape or figure is reduced or increased appropriately to form an image.
Two lines are said to be perpendicular when the measure of angle between is a right angle. While two or more lines are said to be parallel is the measure of angle between them is that of a straight line.
Thus, the appropriate statement that would be concluded considering the conditions in the question is line RS is parallel to line R'S'.

Find the inverse of the following function. f(x) 8√ x for x > 0
Answer: The inverse of a function is found by switching the positions of the input and output values in the function. For example, if the function is f(x) = 2x, the inverse would be f<sup>-1</sup>(x) = x/2.
In the case of the given function, f(x) = 8√ x, the inverse can be found by switching the positions of the input and output values. This gives us f<sup>-1</sup>(x) = √ x/8. This means that if x is the input value, the output value will be √ x/8. Note that the domain of the inverse function is the range of the original function, and the range of the inverse function is the domain of the original function. In this case, the domain of f<sup>-1</sup>(x) is [0, ∞) and the range is [0, ∞), since these are the range and domain of the original function.
Here is the complete inverse function:
f<sup>-1</sup>(x) = √ x/8 for x > 0.

A groundskeeper needs grass seed
to cover a circular field, 290 feet in diameter.
A store sells 50-pound bags of grass seed. One pound of grass seed covers about 400 square feet
of field.
What is the smallest number of bags the groundskeeper must buy to cover the circular field?
Explain or show your reasoning.
The smallest number of bags to cover the circular field is 3.0 pounds.
Area of a circle.
A circle is a shape that has a curved sides referred to as a circumference. Its area can be determined by;
Area of a circle = [tex]\pi r^{2}[/tex]
where r is the radius of the circle
So that,
the radius of the circular field = 290/ 2
= 145 feet
The area of the circular field = [tex]\pi r^{2}[/tex]
= 22/7 x (145)(145)
The area of the circular field = 66078.57 square feet.
Given a bag has a capacity of 50 pounds, and that one pound of grass seed covers about 400 square feet.
Then,
total pounds in a bag = 50 x 400
= 20000 pounds
the number of bags of grass seed needed = 66078.57 / 20000
= 3.304
The number of bags of grass seed needed = 3.30
Thus, the smallest number of bags the groundskeeper must buy to cover the circular field is 3.0 bags.

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope

a. r = 30%
b. r = 18%
c. r = 70%
d. r = 82%
Answer:
b. r = 18%
Step-by-step explanation:
0.3(0.82)^x:
0.3(0.82)^x:
The 0.82 is getting affected since it is raised to the power of x
Hence, for every iteration of x, the object is becoming 82% of itself.
100%-82%=18%
r = 18% ==> b
Option B is correct, 18% is the rate of decay of the exponential function f(x) = 0.3(0.82)ˣ
What is a function?A relation is a function if it has only One y-value for each x-value.
The exponential function f(x) = 0.3(0.82)^x can be written in the form f(x) = a(b)ˣ, where a = 0.3 and b = 0.82.
In an exponential function of the form f(x) = a(b)ˣ
the base b represents the rate of change.
If b is between 0 and 1, then the function represents exponential decay. The rate of decay r can be found using the formula:
r = (1 - b) x 100%
In this case, b = 0.82, so the rate of decay is:
r = (1 - 0.82) x 100%
= 0.18 x 100%
= 18%
Hence, option B is correct, 18% is the rate of decay of the exponential function f(x) = 0.3(0.82)ˣ

What is the rate of change?The rate of change gives the ratio between the change in one quantity to the change in another quantity.
Linear relationships have a constant rate of change and the rate of change is usually represented as the slope or gradient.
For instance, the number of cans changed from 29 to 57, a difference of 28, as the number of weeks changed from 5 to 9, a difference of 4.
The rate of change can be expressed as 28/4 or 7.
The number of cans after 5 weeks = 29
The number of cans after 9 weeks = 57
The change in weeks = 4 (9 - 5)
The change in the number of cans = 28 (57 - 29)
The rate of change = 7 (28/4)
Thus, we can conclude that Zehra buys 7 cans weekly.

▲DEF has vertices D (-2 ,1 ), E (2,4), and F (3,1) and is dilated by a factor of 3 using the point (1,1) as the point of dilation. The dilated triangle is names ▲D'E'F'.
If your answer is useless then don't answer because last time someone typed random stuff and I was left answerless.
The dilated triangle is names ▲D'E'F' ,
Vertex D' → ( -8, 1)
Vertex E' → (4, 10)
Vertex F' → (7, 1)
What is dilation ?
Reducing the object's size by dilation is a change. The items are enlarged or shrunk through dilation. An image that retains the original shape is created by this alteration. The size of the form does differ, though. A dilatation should either enlarge or decrease the initial form. By using the phrase "scaling factor," this transition is described.
Enlargement is the name given to a dilatation that results in a larger image.
Reduction is what happens when a dilatation results in a smaller picture.
According to question
Since the center of dilation is not at the origin, we can use the following formula in order to find the coordinates of the vertices of the triangle D'E'F':
[tex]D_{(O,k)}(x,y) = (k(x-a) +a, k(y-b) +b)[/tex]
Where "O" is the center of dilation at (a,b) and "k" is the scale factor.
In this case you can identify that:
(a,b) = (1,1)
k = 3
Therefore, susbtituting values into the formula shown above, you get that the coordinates ot the resulting triangle D'E'F, are the following:
Vertex D' → [tex](3(-2-1) +1, 3(1-1) +1) = (-8, 1)[/tex]
Vertex E' → [tex](3(2-1) +1, 3(4-1) +1) =(4,10)[/tex]
Vertex F' →[tex](3(3-1) +1, 3(1-1) +1) =(7,1)[/tex]
hence the vertex of ▲D'E'F' are (D' → ( -8, 1), E' → (4, 10), F' → (7, 1).)
