ANSWER and EXPLANATION
We want to name a line and a plane.
LINE
In naming a line, we use two lettters. The two letters are the letters at the beginning and the end of the line.
Now, from the diagram, we have the following lines:
- nY
- Xm
- Zl
PLANE
A plane is made up of two lines intersecting one another.
In naming a plane, three letters are used, with the letter at the intersection in the middle.
The planes in the diagram are:
- mYn plane
- lRm plane

Thus, the answer is Kelsey is the one who is correct. Because the number of intercepts is different from the number of zeroes.
1) Examining the question, we take into consideration that not all intercepts are zeroes of the polynomial.
In a third-degree polynomial function, there is another kind of intercept. The y-intercept.

Consider this scenario and then answer the next three questions: A land owner wants a good approximation of the width of his stream from point D to point C. At high point B, he lays a carpenter’s square (used to make right angles) so that he can sight along BC and BA. AD = 9.3 ft and BD = 15.7 ft.1) State the corresponding proportional sides between similar triangles ABC and ADB. 2) Calculate the length of segment AB. Round the answer to the nearest tenth. (Hint: Use Pythagorean Theorem)3) Answer the following questions about the previous scenario: (a) Write an algebraic expression to represent the length from A to C. (b) Write a proportion to find the distance across the stream. (c) What is the length across the stream?
Answers
1) Let's consider both triangles ABC and ADB:
Then the proportional sides between similar triangles is:
[tex]\frac{AB}{AD}=\frac{BC}{BD}=\frac{AC}{AB}[/tex]2)Since we have that AD=9.3 and BD=15.7, using the pythagorean theorem we get the following:
[tex]\begin{gathered} AB^2=AD^2+DB^2 \\ \Rightarrow AB^2=(9.3)^2+(15.7)^2=86.5+246.5=333 \\ \Rightarrow AB=\sqrt[]{333}=18.2 \\ AB=18.2 \end{gathered}[/tex]Therefore, AB=18.2 ft
3)a)the best way to represent the length from A to C is with the pythagorean theorem:
[tex]AC=\sqrt[]{AB^2+BC^2}[/tex]b)The proportion to find the distance across the stream is the segment DC, then:
[tex]\frac{AD}{BD}=\frac{DB}{DC}[/tex]c)We can find the length by using the values for AD, BD and DB that we previously got:
[tex]\begin{gathered} AD=9.3 \\ BD=15.7 \\ \Rightarrow\frac{9.3}{15.7}=\frac{15.7}{DC} \\ \Rightarrow DC\cdot(\frac{9.3}{15.7})=15.7 \\ \Rightarrow DC=\frac{15.7}{(\frac{9.3}{15.7})}=26.5 \\ DC=26.5 \end{gathered}[/tex]Finally, we have that the length across the stream is 26.5 ft

What is the slope intercept equation for the following line
Answers
The equation of the line in slope-intercept form is: y = -1/2x - 3.
How to Write the Equation of a Line in Slope-Intercept Equation?The equation of a line can be expressed as y = mx + b, which is in the slope-intercept form, where m is the slope of the line and b is the y-intercept of the line.
Using two points on the line, (0, -3) and (-2, -2):
Slope (m) = (-2 -(-3))/(-2 - 0)
Slope (m) = (-2 + 3)/(-2)
Slope (m) = 1/-2
Slope (m) = -1/2.
The y-intercept (b) of the line is, -3.
To write the equation of the line, substitute m = -1/2 and b = -3 into y = mx + b:
y = -1/2x - 3

The forces were balanced due to the biker's inertia.
The forces were unbalanced due to the action-reaction pair required to turn.
Answers
The forces were balanced due to the biker's inertia. Option C.
Objects that move in circles or along circular orbits experience a centripetal force. That is there is a physical force pushing or pulling an object toward the center of the circle. The centripetal force that causes the car to spin in a circle is generated by the friction between the tires and the road surface. A minimum coefficient of friction is required. Otherwise, the car will travel a curve with a larger radius and leave the lane.
As the motorcycle climbs the loop friction forces act along the direction of travel to prevent gravity from slowing it down. As the motorcycle descends the loop friction forces act against the direction of motion preventing acceleration due to gravity. Whenever the velocity increases at the same rate, we are moving with constant acceleration. Centripetal force supports the circular motion. One idea is that if the road is smooth the car can't make a circle.

What is the original price?
Answers
Using the concept of Percentage, the original price of the table is $625.
What is Percentage?A Percentage means a ratio with the second part being 100. Percentage refers to parts per hundred. The term is derived from the Latin phrase per centum, which means "per hundred." In mathematics, the symbol % stands for percent.
Example: 50% means 50 out of every 100. So if 50% of 200 students are girls, then there are 100 students who are girls.
We know that,
Table was sold at $400.
Discount given is 36% then the table is sold at,
100% - 36% = 64%
Let the original price be p then,
64% of p = 400
That gives,
p = [tex]\frac{40000}{64}[/tex]
p = 625
Hence, The original price of the table is $625.
