Answer: Point C is (0, -7)
Step-by-step explanation:
For a general line y = a*x +b
A perpendicular line to this one will have a slope equal to -(1/a)
First, for a line y = a*x + b that passes through points (x₁, y₁) and (x₂, y₂) the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Then for a line that passes through the points A (-4, 5) and B (5, 8) the slope is:
a = (8 - 5)/(5 - (-4)) = 3/9 = 1/3
a = 1/3
Then, a line perpendicular to this one will have the slope:
a' = -(1/(1/3) = -3
Then the perpendicular line is something like:
y = -3*x + b
Now we know that this line passes through point A, then when x = -4, we have y = 5
if we replace these values we get:
5 = -3*(-4) + b
5 = 12 + b
5 - 12 = b
-7 = b
Then our line is:
y = -3*x - 7
This line intersects the y-axis at point C, we know that the y-axis corresponds to x = 0.
Then:
y = -3*0 - 7
y = -7
The point C is (0, -7)

The state volleyball association invited 64 teams to compete in a tournament.after each round , half The teams were eliminated.which equation represents the number of teams,t, that remained in the tournament after r rounds
A. t= 64(0.5)^r
B. t=64(r)^0.5
C. t=64(1.5$^r
D. t=64(-0.5)^r
Answer:
A
Step-by-step explanation:
You take the 64 teams, split it in half, and then the exponent is r
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]
Option A is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: 3x + 3 = 4 is an equation.
We have,
Number of teams = 64
The number of teams eliminated after each round = Half the team.
The equation represents the number of teams t that remained in the tournament after r rounds.
t = 64 x [tex](1/2)^{r}[/tex] ____(1)
Put r = 1, we must get 32 teams.
t = 64 x 1/2 = 32
Put r = 2 we must get 16 teams.
t = 64 x (1/2)² = 64 x 1/4 = 16
We see that (1) is the correct equation to represent the number of teams t that remained in the tournament after r rounds.
Thus,
The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]
Option A is the correct answer.

A shopkeeper wants to sell pulses at a common rate.So he mixed three quality of pulses weighing 34.650 kg ,68.275 kg and 90.350 kg respectively . Find the total quality of pulse he has. What can you say about the shopkeeper?
Answer:
Q = 193.27 kg
Step-by-step explanation:
A shopkeeper mixed three quality of pulses weighing 34.650 kg ,68.275 kg and 90.350 kg respectively.
We need to find the total quality of pulse he has. It means, total quality of pulse he has is :
Q = 34.650 + 68.275 +90.350
= 193.27 kg
Hence, he has 193.27 kg pulse.
There is a flowerbed that is in the shape of a trapezium.Its area is 700m2.The sum of ts upper base and lower base is 70m.Find its height. longman workbook 5A p42 *10
Answer:
h = 16 m
Step-by-step explanation:
Given that,
The area of a trapezium, A = 700 m²
The sum of the length of the parallel sides = 70 m
The area of a trapezium is given by :
[tex]A=\dfrac{1}{2}\times \text{sum of parallel sides}\times height\\\\h=\dfrac{2A}{Sum}\\\\=\dfrac{2\times 700}{70}\\\\=20\ m[/tex]
So, the height of the flower bed is 20 m.

A band is traveling to a new city to perform a concert. The revenue from their ticket sales is a function of the ticket price, x , and can be modeled with (x - 6)(250 - 5x). What are the two ticket prices at which the band would make no money at all?
Answer:
[tex]x=6,50[/tex]
Step-by-step explanation:
The revenue from their ticket sales is a function of the ticket price, x , and can be modeled with [tex](x-6)(250-5x)[/tex]
To find the two ticket prices at which the band would make no money at all, solve the following equation:
[tex](x-6)(250-5x)=0\\x-6=0\,,\,250-5x=0\\x=6\,,\,5x=250\\\\x=6\,,\,x=\frac{250}{5}\\\\x=6,50[/tex]
The two ticket prices at which the band would make no money at all is 6, 50.
Calculation of the two ticket prices:Since the revenue from their ticket sales is a function of the ticket price, x , and can be modeled with (x - 6)(250 - 5x).
So here it can be like
(x - 6) (250 - 5x) = 0
x - 6 = 0, 250 - 5x = 0
x = 6, 5x = 250
x = 5, x = 50
hence, The two ticket prices at which the band would make no money at all is 6, 50.

Find the equation of the line that contains the points whose coordinates are (−1, 0) ( − 1 , 0 ) and has slope 1/4
Answer:
[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]
Step-by-step explanation:
We want to find the equation of the line that passes through the point (-1, 0) and have the slope 1/4.
We can use the point-slope form given by:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
We will substitute (-1, 0) for (x₁, y₁) and 1/4 for the slope m. Therefore:
[tex]\displaystyle y-(0)=\frac{1}{4}(x-(-1))[/tex]
Simplify:
[tex]\displaystyle y=\frac{1}{4}(x+1)[/tex]
Distribute. Thus, our equation is:
[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]

The sum of two numbers is 115. Their difference is 21. Find numbers. I need to show my answer
Answer:
The answer is 73 and 42
Step-by-step explanation:
1. Subtracting 21 from 115 which gives you 94, but that wouldn't be the answer because its asking for two numbers with a difference.
2. From you subtract 21 from 94 which is 73, next subract 73 from 115 which gives you 42.
3. 73 + 42 is 115
