The steps of student B are in the correct order but the steps of student A are in the incorrect order.
What is a perpendicular and parallel line?Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines and the lines that never intersect are known as parallel lines.
We have:
You are given AB and point C. Construct a line parallel to AB that passes through point C
The correct way to draw a parallel line to AB that passes through point C is:
1. Draw a line that intersects points B and C.2. Place the compass on point B, and swing an arc that crosses line AB and line BC. Label the points D and E.3. Keep the compass at the same width, and place it on point C.4. Swing an arc that crosses line BC, and label the point F.5. Open the compass to the width between points D and E.6. Keeping the compass at the same width, place it on point F.7. Swing an arc that intersects the arc created from line BC at point C.8. Mark the intersection of the two arcs as point G.9. Draw a line through point C and point G.The steps of student B are in the correct order but the steps of student A are in the incorrect order.

9x-7=-52
Show all work and justify each step
Answer:
x = -5
Step-by-step explanation:
9x - 7 = -52
we want to single out x,
add 7 to both sides to be one step closer to getting x alone
9x - 7 + 7 = -52 + 7
9x = -45
divided both sides by 9 to get x alone
9x / 9 = -45 / 9
x = -5
Let me know if you need any clarification!
[tex] 9x - 7 = - 52[/tex]
Firstly rearrange the variable on the left side of the equation...
[tex]9x = - 52 + 7[/tex]
Calculate the sum or differences

Answer: x²-59x+114=0
explanation:
If the roots are 2 and 57, then:-
sum of roots = 2+57 = 59
and, product of roots = 2×57 = 114
the quadratic equation is given by,
x²-(sum of roots)x+(product of roots)=0
so, x²-59x+114=0 will be the desired quadratic equation.
so, none of the options are correct.
the correct answer is x²-59x+114=0.

Hope it help youA cyclist is stationary when a second cyclist passes travelling at a constant speed of 8 m s−1. The first cyclist then accelerates for 5 s at a constant rate of 2 m s−1 before continuing at constant speed until overtaking the second cyclist. By sketching both graphs, find the equations of the two straight line sections of the graphs and hence find how long it is before the first cyclist overtakes the second.
Answer:
im not too sure about that sorry!
Step-by-step explanation:
uiwgorihvncjkdnskv
It takes 15 seconds for the first cyclist to overtake the second cyclist.
How can you find how long it took before the first cyclist overtakes the second?First, identify the two phases of the first cyclist's motion.
Phase 1: The cyclist accelerates from rest to a constant speed of 8 m/s.
Phase 2: The cyclist travels at a constant speed of 8 m/s.
Find the equations of the two straight-line sections of the graph.
The equations of the two straight-line sections of the graph are as follows:
Phase 1:
s = [tex]2t^2[/tex]
Phase 2:
s = 8t
where s is the distance traveled by the cyclist and t is the time
Set the two equations equal to each other to find the time it takes the first cyclist to overtake the second cyclist
The first cyclist overtakes the second cyclist when the first cyclist has traveled a distance of 8 m more than the second cyclist.
Let t be the time it takes the first cyclist to overtake the second cyclist.
The distance traveled by the first cyclist is then 8t, and the distance traveled by the second cyclist is 8(t - 5).
Setting these two expressions equal to each other, we get:
8t = 8(t - 5)
Solving for t, we get:
t = 15
Therefore, it takes 15 seconds for the first cyclist to overtake the second cyclist

-------------------------------------------------------------------------------------------------------------
Given: [tex]\textsf{Slope = -6/5, Goes through (0, 2)}[/tex]
Find: [tex]\textsf{The equation in point-slope form}[/tex]
Solution: We need to take the values that were given to us and plug them into the point-slope form. It doesn't seem like the problem is asking for anything more than that so we will leave it at that.
Plug in the values
[tex]\textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}[/tex][tex]\textsf{y - 2 = -6/5(x - 0)}[/tex]Since the problem is just asking for the equation in point-slope form the final expression would be y - 2 = -6/5(x - 0).
Answer:
[tex]\sf y - 2 = -\dfrac{6}{5}(x - 0)[/tex]
Step-by-step explanation:
[tex]\sf \large \underline{\textsf{Given:}}\ \textsf{a line with a slope of $-\dfrac{6}{5}$, and a y-intercept of $2$}[/tex]
We're given a y-intercept of 2, but using the slope-intercept form, we can immediately determine that x = 0. Hence, the given point is (0, 2).
Then, we substitute these values into the Point-Slope Form to find the equation.
Here are both forms for future reference:
⇒ Slope-Intercept Form: y = mx + b
[ Where: m is the slope, and b is the y-intercept (when x = 0). ]
⇒ Point-Slope Form: y - y₁ = m(x - x₁)
[ Where: m is the slope, and (x₁, y₁) is a given point. ]
Substitute the values into the Point-Slope Form:

Which of the following values can be found by using the formula √1+tan^2 0?
cos and sec can be found
The requried simplified expression is 1 / cosØ, which is equivalent to secØ. The correct option is secØ.
Let's simplify the given expression and see which of the provided options match:
We are given the expression √(1 + tan²Ø).
Now, recall the trigonometric identity: tan²Ø = sin²Ø / cos²Ø.
Substitute this identity into the expression:
√(1 + sin²Ø / cos²Ø)
Next, find a common denominator for the fraction inside the square root:
√((cos²Ø + sin²Ø) / cos²Ø)
Since cos²Ø + sin²Ø = 1 (as per the Pythagorean trigonometric identity), the expression becomes:
√(1 / cos²Ø)
Now, we can take the square root of 1 and cos²Ø separately:
√1 / √cos²Ø
Simplify:
1 / cosØ
The simplified expression is 1 / cosØ, which is equivalent to secØ.
Therefore, the correct option is: secØ.
