Option (A) one side of a triangle is the object that best describes the term line segment is the correct answer.
What is a line segment?
A line segment is a part of line that is bounded by two distinct end-points. A line segment has a fixed length. Figures such as a triangle, polygon, hexagon, square are made of different numbers of line segments.
For the given situation,
A line segment is a portion or piece of a line that allows you to build polygons, determine slopes, and make calculations.
From the definition of line segment we know that the object that best describes the term line segment is one side of a triangle.
Hence we can conclude that option (A) one side of a triangle is the object that best describes the term line segment is the correct answer.
You work as an assistant for a local musical theatre group, the Main Street Theatre Company. The company is putting on a production of Les Misérables this year, and they need your help planning it.
Since the role of young Cosette is played by a child, the Main Street Theatre company must actually cast 3 girls in the role of young Cosette, and alternate girls from night to night. (This is because of restrictions on working hours for children.) You have received headshots and resumes from 25 girls who wish to audition for young Cosette.
Does order matter when casting the 3 young Cosettes? (In other words, are young Cosette 1, young Cosette 2, and young Cosette 3 different parts?)
No, all three girls will play the same part.
Yes, even though they will all be playing the same part, it will be on different nights.
No, all three girls will get paid the same amount.
Yes, young Cosette 1, young Cosette 2, and young Cosette 3 are all different parts.
The inference based on the information about ordering is that D. Yes, young Cosette 1, young Cosette 2, and young Cosette 3 are all different parts.
What is an inference?It should be noted that a inference simply means the conclusion that can be deduced based on the information given.
In this case, the Main Street Theatre company must actually cast 3 girls in the role of young Cosette.
Hence, young Cosette 1, young Cosette 2, and young Cosette 3 are all different parts. Therefore, ordering matters.

A bank loaned out $19,500, part of it at the rate of 11% annual interest, and the rest at 7% annual interest. The total interest earned for both loans was $1,485.00. How much was loaned at each rate?
____ was loaned at 11% and
____was loaned at 7%.
The amount loaned at the interest rate of 11% is $3000.
The amount loaned at the interest rate of 7% is $16,500
What are the linear equations that represent the question?0.11a + 0.07b = 1485 equation 2
Where:
a = amount loaned at the interest rate of 11%
b = = amount loaned at the interest rate of 7%
How much was loaned at 11% and 7%In order to determine how much was loaned at 7%, take the following steps:
Multiply equation 1 by 0.11:
.11a + 0.11b = 2145 equation 3
Subtract equation 2 from equation 3:
0.04b = 660

who knows how to sketch these kinds of graphs need help asap
Answer:
We first need to know the graph of the basic function belonging to the trigonometric family, which is sin x.
Now we need to apply basics of functions to get the graph of y = -sinx from y = sinx
If x is the input in the y = sinx , then sin x will be the output which will be represented on the y axis. Eg :
If x = pi/2
then output will be y = sin(pi/2) = 1
Hence in the graph of sinx, at x =pi/2 the value of y is 1.
Once we have understood this, we can use the same logic in the case
y = -sinx
If x = pi/2
then output will be y = - sin(pi/2) = -1
Here we can see that the output of y = - sin x will be the exact negative of of the output of y = sinx
Hence all portions of the graph of y = sinx in the +y axis will come down to the -y axis for y = -sin x, i.e we will be taking mirror image of the graph along the x axis. Below are the graphs of y=sinx and y= - sinx respectively for your reference:

A large washer has an outer radius of 10mm and a hole with a diameter of 14mm. What is the area of the washer? (Use π =3.14)
Answer:
160.14 mm^2
Step-by-step explanation:
Area of a circle = pi r^2
subtract the area of the smaller circle from the larger
note that the smaller radius = 7 mm
pi ( 10^2 - 7^2 ) =
3.14 ( 51) = 160.14 mm^2
The area of the washer is approximately 160.14 square millimeters.
Use the concept of the circle defined as:
A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.
The line of reflection symmetry is formed by all lines that traverse the circle.
Additionally, every angle possesses rotational symmetry around the center.
Given that,
The outer radius of the washer: 10mm
Diameter of the hole: 14mm
π value to be used: 3.14
To find the area of the washer:
Subtract the area of the hole from the area of the outer circle.
The area of a circle is given by the formula A = πr²,
Where r is the radius.
For the outer circle:
The radius is 10mm, so the area of the outer circle = 10²π.
The area of the outer circle = 100π mm²
For the hole,
The diameter is 14mm,
So the radius of the hole = 7 mm.
The area of the hole = 7²π
The area of the hole = 49π mm²
To find the area of the washer,
Subtract the area of the hole from the area of the outer circle:
Area of washer = Area of the outer circle - Area of hole
Area of washer = (100π - 49π) mm²
Area of washer = 51π mm²
Area of washer ≈ 160.14 mm²
Hence,
The area of the washer is approximately 160.14 square millimeters.

Using the line of best-fit, it is found that:
50% power is obtained after 16.8 minutes.90% power is obtained after 30.1 minutes.How to find the equation of linear regression using a calculator?To find the equation, we need to insert the points (x,y) in the calculator.
In this problem, the points are:

Hence, using a calculator, the estimate for the battery after x minutes is given as follows:
y = 3x - 0.333.
50% power is obtained when y = 50, hence:
50 = 3x - 0.333
x = 50.333/3
x = 16.8 minutes.
90% power is obtained when y = 90, hence:

Marisol did a mistake while grouping the terms in Step 1, with the sign. Thus, Marisol should go back and group the terms in Step 1 as (6x³ - 22x²) - (9x - 33). Hence, the second option is the correct choice.
The polynomial Marisol had was 6x³ - 22x² - 9x + 33.
The steps she did in the grouping of terms and factoring out the GFC out of the groups were:
Step 1: (6x³ - 22x²) - (9x + 33).
Step 2: 2x²(3x - 11) -3(3x + 11).
After this Marisol was unable to get a common factor to proceed further.
The mistake that Marisol did was in Step 1, as while grouping -9x and +33, she took the minus sign out, which will make -9x to become 9x, but 33 to become -33.
This is where she made the mistake and writing - (9x + 33) in place of - (9x - 33).
Thus, her steps should have been:
Step 1: (6x³ - 22x) - (9x - 33),
Step 2: 2x²(3x - 11) -3(3x - 11), which gives her a common factor (3x - 11), to continue with the third step:
