Write your question here (Keep it simple and clear to get the best answer)striangle has vertices A(2;5); B(1;-2) and C(-5;1). Determine:(a) the equation of the line BC. (b) The equation of the perpendicular line from A to Bc
(a) y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex]
(b) y = 2x + 3
Step-by-step explanation:
(a) The equation of a line given by points M(x₁, y₁) and N(x₂, y₂) is given by:
y - y₁ = m(x - x₁) -------------------(i)
Where;
m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = slope or gradient of the line ---------------(ii)
Given points on the triangle are:
A(2,5)
B(1,-2)
C(-5,1)
To find the equation of line BC, we use the formulas in equations (i) and (ii) where the points of the line are B(1,-2) and C(-5,1) and;
x₁ = 1
y₁ = -2
x₂ = -5
y₂ = 1
==> First get the gradient using equation (ii) as follows;
m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = [tex]\frac{1 - (-2)}{-5 -1}[/tex]
m = [tex]\frac{3}{-6}[/tex]
m = [tex]\frac{-1}{2}[/tex]
==> Now, use equation (i) to find the equation of the line as follows;
y - (-2) = [tex]\frac{-1}{2}[/tex](x - 1)
y + 2 = [tex]\frac{-1}{2}[/tex](x - 1)
Multiply both sides by 2
2(y+2) = -1 ( x - 1 )
2y + 4 = -x + 1
2y = -x + 1 - 4
2y = - x - 3
y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex]
Therefore, the equation of the line is y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex]
(b) To find the perpendicular line from A to BC, note that
i. two lines are perpendicular if they meet at 90°
ii. the general equation of a line could also be written as y = mx + c where m is the slope and c is the intercept.
iii. when one line has a slope of m, then a perpendicular line to that line will have a slope of [tex]\frac{-1}{m}[/tex]
The equation of line BC is y = [tex]\frac{-1}{2}[/tex]x - [tex]\frac{3}{2}[/tex].
This means that BC has a slope of [tex]\frac{-1}{2}[/tex]
A perpendicular line from A to BC will have a slope of 2.
Now to get the equation of this perpendicular line from A(2, 5) to BC, we use the general equation of a line given in equation (i)
where;
m = 2
x₁ = 2
y₁ = 5
Substitute these values into equation (i)
y - 5 = 2(x - 2)
Solving by simplification gives;
y - 5 = 2x - 2
y = 2x + 3
Therefore, the equation of the perpendicular line is y = 2x + 3

A kite and its tail total 48 ft in length. the tails is 7 times the length of the body. How long is the kite's tail?
Answer:
42 ft
Step-by-step explanation:
body = x
tail = 7x
x + 7x = 48
8x = 48
Divide both sides by 8
x = 6
Tail
7x = 7(6)
7x = 42

Determine the length of the chord that is 8 inches from the center of a circle with a radius of 17 inches?
Answer:
30 in
Step-by-step explanation:
See attached image.
The length of AB is 17 (radius). The length of AC is 8 (given info).
AC splits segment BD in half, so point C is the midpoint of segment BD.
AC is perpendicular to the chord, so triangle ABC is a right triangle. You now have a right triangle with a leg of length 8 and hypotenuse of lenght 17.
The Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2.
[tex]8^2+(BC)^2=17^2\\\\64+(BC)^2=289\\\\(BC)^2=225\\\\BC=\sqrt{225}=15[/tex]
That's half the length of the chord, so double that to get 30 inches for the full length of the chord BD.

Sabrina has gone to work the last 50 days. On 28 of those days, she arrived before 7:30 A.M. On the rest of the days, she arrived after 7:30 A.M. What is the experimental probability that she will arrive at work before 7:30 A.M. On her next day of work? What is the experimental probability that she will arrive after 7:30 A.M.?
Answer:
Prob (Arrive before 7.30) = 14 / 25 ; Prob (Arrive after 7.30) = 11 / 25
Step-by-step explanation:
Prob (Arrive before 7.30) = No. of days before 7.30 arrival / Total work days
= 28 / 50 = 14 / 25
Prob (Arrive after 7.30) = No. of days after 7.30 arrival / Total work days
= (50 - 28) / 50 = 22 / 50 = 11 / 25
or , 1 - Prob (Arrive before 7.30) = 1 - 14/25 = (25 - 11) / 25 = 11/ 25

It is 9.9cm
Answer:
9.9cm
Step-by-step explanation:
If side h cm is opposite of 51° and side 8cm is adjacent to 51°, use the tangent function to calculate the opposite side h cm:
tan(51°)=opposite/adjacent=h/8
tan(51°)=h/8
8tan(51°)=h
9.879177252=h
9.9=h
Therefore, the value of h is 9.9cm

Find the surface area of this triangular prism. Be sure to include the correct unit in your answer.
Answer:
[tex]390ft^2\\[/tex]
Step-by-step explanation:
Ok so we have 2 (congruent) triangles and 3 rectangles.
Your main approach to this problem should be to find the area of each of the faces and adding them up to get to your final answer. Your question makes a point of including the correct unit in your answer. Since this is surface area, the unit would be [tex]ft^2[/tex]
Now let's start:
First, I am going to start with finding the area of the rectangles.
[tex]12\cdot11=132\\13\cdot11=143\\5\cdot11=55\\\\55+143+132=330[/tex]
Alright, next lets move on to the triangles.
They are both the same, if you notice. So find one and double it.
[tex]12\cdot5=60\\\frac{60}{2}=30\\30\cdot2=60[/tex]
now lets add em all
330+60
= 390 and thats your final answer, dont forget to include the unit, ft^2

Determine the area of a circle whose diameter is 8 in Use 3. 14 for TT Enter your answer in the box. Round to the nearest hundredth, if necessary. A= blank inches squared
Answer:
50.24
Step-by-step explanation:
Area = pi*r^2
r = diameter/2
r = 4
Area = pi*4^2
Area = 3.14*16
Area = 50.24
Answer:
Step-by-step explanation:
The area A of a circle of radius r is A = πr², where π is often approximated by 3.14.
Here, with the circle diameter being 8, we figure the radius to be half that, or 4.
Then the area of this circle is A = (3.14)(4 in)², or
A = 50.24 in²
Luanne and Fiona each made a salt water solution. Luanne mixed 3 cups of salt with every gallon of water. Fiona mixed 2 cups of salt with every 3 gallons water. Which of these statements is true?
Answer:
See Explanation
Step-by-step explanation:
Given
Luanne
[tex]Salt = 3\ cups[/tex]
[tex]Gallon = 1[/tex]
Fiona
[tex]Salt = 2\ cups[/tex]
[tex]Gallon = 3[/tex]
The question is incomplete, as the options are not given.
However, possible comparison that can be made are
(a) The unit amount of salt
(b) Whose solution is more concentrated with salt
(a) The unit amount of salt
To do this, we divide the amount of salt by the number of gallons.
[tex]Unit = \frac{Salt}{Gallon}[/tex]
For Luanne
[tex]Unit = \frac{3}{1}[/tex]
[tex]Unit = 3 cups/gallon[/tex]
For Fiona
[tex]Unit = \frac{2}{3}[/tex]
[tex]Unit = 0.67cups/gallon[/tex]
(b) Whose solution is more concentrated with salt
By comparing the result in (a)
We have:
[tex]Unit = 3 cups/gallon[/tex] --- Luanne
[tex]Unit = 0.67cups/gallon[/tex] --- Fiona
Luanne unit amount implies that there are 3 cups in every gallon of water;
Fiona unit amount implies that there are 0.67 cups in every gallon of water;
[tex]3 >0.67[/tex]
Hence, Luanne solution is more concentrated with salt

Doug worked out for 256 minutes.
Doug has an enemy named Cathy
Cathy worked out a total of 4 hours and 15 minutes.
Who worked out more? What was the difference in minutes?
Answer:
Step-by-step explanation:
Cathy worked 4 hours.
4 hours = 4 * 60 = 240 minutes
She worked an additional 15 minutes which brings her total up to 255.
Doug worked 1 minute longer than Cathy.
Answer:
a.) Doug worked more. b.)The difference is one minute.
Step-by-step explanation:
CAN BE DONE DIFFERENTLY
Cathy has 4 & 15 minutes, since each hour is 60 minutes we can multiply 60 by 4.
60
x4
240
Now adding the 15 it'll be 255.
DOUG WORKED MORE.
DIFFERENCE IS 1 MINUTE.

Keisha and her family travel 227 miles on Monday and 337 Miles on Tuesday her brother drives 1/4 of the distance they travel on Monday and Tuesday and her mom drives the rest her mom also drives 150 miles on Wednesday.
How many more miles does her mom drive then her brother in all?
Answer:
her mother drives 142 miles more than her brother.
Step-by-step explanation:
227 + 337 = 564 miles in total driven
¼ of 564 miles = 136 miles (what her brother drives of the 564 miles)
564 - 136 = 428 left
her mother drives 428-150 miles from Wednesday = 278
278-136=142
