Safara uses these steps to partition segment in a ratio of 9:4.
1. Draw horizontal segment.
2. Count squares and place point to partition segment so that :=9:4.
3. Draw a vertical segment from point to where it intersects segment. Call this point.
Which is the best reason why Safara’s method works?
Pls answer in top right,left, btm right left
Lines can be divided into segments by using the line segment ratios
The reason why the Safara's method works is (d) Triangles ABE and ACD can be proved to be similar
How to determine the reason
The line ratio is given as
Ratio = 9 : 4
When the line is divided by the vertical and the horizontal lines, the segments form similar triangles ACD and ABE (see attachment)
Hence, the reason why the Safara's method works is that:
Triangles ABE and ACD can be proved to be similar

Find the 9th term of the geometric sequence whose common ratio is 1/3 and whose first term is 2.
Answer:
2/6561
Step-by-step explanation:
Geometric sequence formula : [tex]a_n=a_1(r)^n^-^1[/tex]
where an = nth term, a1 = first term , r = common ratio and n = term position
given ratio : 1/3 , first term : 2 , given this we want to find the 9th term
to do so we simply plug in what we are given into the formula
recall formula : [tex]a_n=a_1(r)^n^-^1[/tex]
define variables : a1 = 2 , r = 1/3 , n = 9
plug in values
a9 = 2(1/3)^(9-1)
subtract exponents
a9 = 2(1/3)^8
evaluate exponent
a9 = 2 (1/6561)
multiply 2 and 1/6561
a9 = 2/6561

Factor the given expression completely and show your work. 6x^2-5x-21. Check your answer and show that work as well.
PLSS SOLVEEEEE GIVING BRAINILYYYYYYYY!!!!!!!!!
Answer:
(2x + 3)(3x - 7)
Step-by-step explanation:
Factorize 6x² - 5x - 21
Find two numbers which are factors of the product of the coefficient of x² and the constant, and sum to the coefficient of x.
coefficient of x² mulitplied by the constant = 6 x -21 = -126
So we need to find two numbers that multiply together to make -126 and sum to -5.
Factors of -126 that sum to -5: 9 and -14
As 9 x -14 = -126, and 9 - 14 = -5
Rewrite the center term of the quadratic as these numbers, so - 5x becomes 9x - 14x:
⇒ 6x² + 9x - 14x - 21
Factorize each pair of terms, checking that the bracket created is the same:
⇒ 3x(2x + 3) - 7(2x + 3)
The first bracket is the common factor of (2x + 3) and the second bracket is the factorized terms outside of each bracket (3x - 7). So the final factorization is:
(2x + 3)(3x - 7)

Answer:
y = [tex]\frac{1}{3}[/tex] x + 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y = 4 ( subtract 3x from both sides )
y = - 3x + 4 ← in slope- intercept form
with slope m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-3}[/tex] = [tex]\frac{1}{3}[/tex]
Given c = 2 , then
y = [tex]\frac{1}{3}[/tex] x + 2 ← equation of perpendicular line
Find the value of x that maximized the volume of the following:
X
5 - 2x
8 - 2x
O x= 5
O x= 10/3
O x= 1
O x= 2.5
Check the picture below.
as you can see, the graph of the volume function comes from below goes up up up, reaches a U-turn then goes down down, U-turns again then back up to infinity.
the maximum is reached at the close up you see in the picture on the right-side.
Why we don't use a higher value from the graph since it's going to infinity?
well, "x" is constrained by the lengths of the box, specifically by the length of the smaller side, namely 5 - 2x, so whatever "x" is, it can't never zero out the smaller side, and that'd happen when x = 2.5, how so? well 5 - 2(2.5) = 0, so "x" whatever value is may be, must be less than 2.5, but more than 0, and within those constraints the maximum you see in the picture is obtained.
4(3x-3)=-2(76/9+5x)
help please.
Answer: x = -2/9
The correct answer is x = -2/9
Step-by-step explanation:
First, you want to distribute:
4(3x - 3) = -2(76/9 + 5x)
12x - 12 = -2(76/9 + 5x)
The you want to rearrange the terms:
12x - 12 = -2(76/9 + 5x)
12x - 12 = -2(5x + 76/9)
Then you want to distribute again:
12x - 12 = -2(5x + 76/9)
12x - 12 = -10x - 152/9
Then solve:
x = -2/9
Final result:
x = -2/9

The area of a rectangular carpet is (10x2 + 3x – 27) square yards. The length of the carpet is (5x + 9) yards. Which of the following represents the width?
The expression that represents the width of the rectangle is: 2x - 3.
What is the Area of a Rectangle?Area of rectangle = length × width
Given:
Area = (10x² + 3x - 27) sq. yards
Length = (5x + 9) yards
Therefore:
Width = Area of rectangle/length
Width = (10x² + 3x - 27)/(5x + 9)
Factorize the numerator
Width = (5x + 9)(2x - 3)/(5x + 9)
Width = 2x - 3
Therefore, the expression that represents the width of the rectangle is: 2x - 3.

If you flip a coin 24 times, how many times would you predict that the coin lands on tails?
Answer: You have 1/2 a chance that the coin would flip on tales. So that means that tails is most likely to land 12 times on tails.
The number of times you would predict that the coin lands on tails is 1/2.
Given that, a coin flip 24 times.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here, the total number of outcomes = 24
The number of favorable outcomes = 12
Probability of an event = 12/24
= 1/2
Therefore, the number of times you would predict that the coin lands on tails is 1/2.

10. WEATHER On average, the circular eye of a hurricane is about 15 miles in diameter. Gale winds can affect an area up to 300 miles from the storm's center. A satellite photo of a hurricane's landfall showed the center of its eye on one coordinate system could be approximated by the point (80, 26).
a. Write an equation to represent a possible boundary of the hurricane's eye.
b. Write an equation to represent a possible boundary of the area affected by gale winds.
The equation to represent a possible boundary of the hurricane's eye is (x - 80)² + (y - 26)² = 7.5²
Circle Equation
The standard equation of a circle is given by:
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and r is the radius.
Given that diameter = 15 miles, hence radius = 15/2 = 7.5. Also, center = (80, 26)
The equation of circle is:
(x - 80)² + (y - 26)² = 7.5²
The equation to represent a possible boundary of the hurricane's eye is (x - 80)² + (y - 26)² = 7.5²
