The first step in the construction of a line perpendicular to line AB and passing through an external point m is:
a. place the compass needle on m and keeping the compass width the same, draw two arcs that intersect the line AB
What are the steps to construct a perpendicular line from an external point?To construct a perpendicular line, a compass and a scale are used.
Consider a line AB and an external point M.
Step 1:
Place the compass needle on M and keeping the compass width the same, draw two arcs that intersect the line AB.
Step 2:
Name the two intersecting points on line AB as X and Y.
Draw the arcs from these two points to the opposite side of point M with the same compass width.
Step 3:
Name the intersecting point of two arcs as N.
Draw a line connecting the two points M and N using scale.
Step 4:
Using a protractor, measure the angle of the line MN with the line AB.
The angle must show 90°.
Thus, the line MN perpendicular to line AB and passing through an external point M is constructed.

Using it's concept, the probabilities are given as follows:
19. A. 1/3.
20. F. 1/6.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, there are 1 + 1 + 3 + 4 + 3 = 12 papers. 4 have a score of 6, hence, in item 19, the probability is:
p = 4/12 = 1/3.
Which means that option A is correct.
2 papers have a score greater than 12, hence the probability in item 20 is given by:

Write the equation of the line which passes through (5, −2) and (3, 4) in standard form.
Answers
The equation of the line is 3x + y = 1
How to determine the equation of the line?The points are given as:
(5, −2) and (3, 4)
Start by calculating the slope (m)
m =(y2 - y1)/(x2 - x1)
This gives
m = (4 + 2)/(3 - 5)
Evaluate
m = -3
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = -3(x + 2) +5
So, we have:
y = -3x - 6 + 5
Evaluate the like terms
y = -3x - 1
Rewrite as:
3x + y = 1
Hence, the equation of the line is 3x + y = 1

Answer:
b = 21
Step-by-step explanation:
In general for these trig problems look for the angle whose measure you are given or need to find and for the sides you are given lengths or whose sides you need to find.
Given:
side AB = 10 cm
m<C = 25°
Find:
side AC
The angle of interest here is <C whose measure is 25°.
Now look at the given side and the side you are looking for with respect to angle C, the given angle.
For angle C, AC is the adjacent leg.
For angle C, AB is the opposite leg.
Which trig function relates the opposite leg to the adjacent leg?
It is the tangent, since, in general, tan X = opp/adj.
tan C = opp/adj
tan 25° = AB/AB
tan 25° = 10 cm/b
Solve for b.
b × tan 25° = 10 cm
b = 10 cm / tan 25°
Using your calculator, divide 10 by the tangent of 25°.
b = 21.44506...
Answer: b = 21
Answer:
[tex]b = \bf 21 \space\ cm[/tex]
Step-by-step explanation:
• To solve for a side using SOH CAH TOA, first check the angle whose measure is given.
In this case, we know ∠ C is 25°.
• Next we have to figure out the relationships between the given angle and two sides: one side whose length we know, and the other whose length we have to find.
In this case, the side opposite to ∠ C is known to be 10 cm, and the side adjacent to ∠ C is AC, whose length, b, we have to find.
• The trigonometric ratio that relates the adjacent and opposite sides of an angle is tan, where:
[tex]\boxed{tan \theta = \frac{opposite}{adjacent} }[/tex] .
We can use this relationship to calculate the value of b:
⇒ [tex]tan (25 \textdegree) = \frac{10}{b}[/tex]
Solving for b:
⇒ [tex]b \cdot tan (25 \textdegree) = 10[/tex]
⇒ [tex]b = \frac{10}{tan (25 \textdegree)}[/tex]
⇒ [tex]b = 21.45[/tex]
⇒ [tex]b \approx \bf 21 \space\ cm[/tex] (rounded to the nearest whole number)

week, she completed 60 burpees in 5 minutes. This week, she completed
78 burpees in 6 minutes. How many burpees did Faith do per minute last
week and this week?
Please help me I will mark u the brainliest
Answers
Step 1: Write out the beginning for the first unit rate.
Faith completed 60 burpees in 5 minutes last week.
Step 2: Since 60 burpees were completed in 5 minutes, we can divide 60 by 5 to find how many burpees were completed in 1 minute.
60 divided by 5 equals 12.
5 divided by 5 equals 1.
Our fraction for how many burpees Faith did in a minute last week is 12/1. This reduces to 12, meaning that Faith did 12 burpees last week.
Step 3: Find the unit rate for this week.
Faith completed 78 burpees in 6 minutes this week. Because of this, we can divide 78 by 6 to find how many burpees Faith completed this week.
78 divided by 6 equals 13.
6 divided by 6 equals 1.
Our final fraction for how many completed burpees Faith did this week is 13/1, which reduces to 13. Therefore, Faith completed 13 burpees per minute this week.
Your final answer: In terms of separate values, Faith completed 12 burpees per minute last week and 13 burpees per minute this week. If you need help, let me know and I will gladly assist you.

Answers
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
y = ± sqrt( -x/6 -12.666) + 2
