Explanation:
The slope of BC can be calculated
Slope = rise/run
In this case, the rise is the height of the blue triangle and the run is the base of the blue triangle, so
Slope = 2/6 = -2/6
To simplify the slope, we need to divide by 2, so
[tex]\text{Slope}=-\frac{2\div2}{6\div2}=-\frac{1}{3}[/tex]Related Questions

∠ QOR = 35°
Step-by-step explanation:
from the diagram
∠ POQ + ∠ QOR = ∠ POR , that is
24° + ∠ QOR = 59° ( subtract 24° from both sides )
∠ QOR = 35°
Answer the following The sign of a is : a. positive B .Zero C.Negative The value of h is given by h The value of k is given by k
Answers
Since the function is concave up, the leading coefficient a must be positive.
Then: The sing of a is positive
The function is expressed in its canonical form, where h and k are the x and y coordinates of the vertex, respectively.
We can check in the graph that the vertex coordinates are (-5,-4).
Therefore, we have:
The value of h is given by h = -5
The value of k is given by k = -4

Answer: 6 a: 1=30 2=44, 3=106 4=30
Step-by-step explanation:
well, 3 is the opposite of 106 so they are equal, 2 is the opposite of 44 so they are equal, then you can just take the straight line and subtract the ones around it from 180 to find the 1 or 4, so 180-106, then 74-44=30. then because 1 and 4 are on opposite sides, they are equal. Sorry for not having enough times for all problems, but to help with 6 and 7, just remember that opposites are equal (you can use in 6b and 7a) and the if they make a straight line they make 180 degrees (use in 7b)

Five thousand tickets are sold at $1 each for a charity raffle. Tickets will be drawn at random and monetary prizes awarded as follows: 1 prize of$500; 3 prizes of $100, 5 prizes of$20, and 20 prizes of $5. What is the expected value of this raffle if you buy 1 ticket?
Answers
As per the unitary method, the expected value of this raffle if you buy 1 ticket is $ 0.25.
Unitary method:
Basically, the word unitary refers to a single or an individual unit.
Therefore, this method aims at determining values in relation to a single unit.
Given,
Here we have that five thousand tickets are sold at $ 1 each for a charity raffle, and tickets are to be drawn at random and monetary prizes awarded as follows:
1 prize of $ 500,
3 prizes of $ 200,
5 prizes of $ 10, and
20 prizes of $ 5,
And here we need to determine what is the expected value of this raffle if you buy 1 ticket.
As per the given details, let us consider X be the expected value then we have written it as the equation like the following,
(500 + 3 x 200 + 5 x 10 + 20 x 5) / 5000 = X
When we simplify it then we get,
(500 + 600 + 50 + 100) / 5000 = X
After the addition operation we get the value,
1250/5000 = X
Then the value of X can be written as,
0.25 = X
Therefore, the expected value of this raffle per ticket is $ 0.25.

Write a function $g$ whose graph represents the indicated transformation of the graph of f the equation f(x)=x+2 translated 2 units to the right is g(x)=
Answers
The function g(x) whose graph represents the indicated transformation of the graph of the equation f(x) = x+2 translated 2 units to the right is g(x) = x
Here the function is
f(x) = x+2
It is translated 2 units to the right
A translation defined as the movement of the graph either horizontally or vertically. In translation the shape or the size of the graph will not change only the location of the graph changes
Then the equation will be
f(x-2) = (x-2)+2
= x-2+2
= x
Hence, the function g(x) whose graph represents the indicated transformation of the graph of the equation f(x) = x+2 translated 2 units to the right is g(x) = x
The complete question is

what amount of time in months is necessary for a principal of $6,000 to produce $550 and interest at 10%?
Answers
the compound interest formula is given by
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]where A is the amount you will have, P is the principal, r is the annual interest rate, n is the amount of times the interest is compounded per time period, and t is the amount of time.
In our case, we need to find the time t. Then, by moving the Principal to the left hand side, we get
[tex]\frac{A}{P}=(1+\frac{r}{n})^{nt}[/tex]By applying natural logarithm on both sides, we get
[tex]\ln (\frac{A}{P})=nt\cdot ln(1+\frac{r}{n})[/tex]now, we can isolate t as
[tex]t=\frac{\ln (\frac{A}{P})}{n\ln (1+\frac{r}{n})}[/tex]Now, we can substitute our given values into this expression. It yields,
[tex]t=\frac{\ln (\frac{6550}{6000})}{12\ln (1+\frac{0.1}{12})}[/tex]which gives
[tex]t=\frac{0.0877}{12(0.0083)}[/tex]then, the time (in years) is
[tex]t=0.88\text{ years}[/tex]Now, we must convert this result in months. Since 1 year has 12 months, we have
[tex]\begin{gathered} t=0.88\times12 \\ t=10.56\text{ months} \end{gathered}[/tex]that is, the answer is 10.56 months

A rectangular board is 1200 millimeters long and 800 millimeters wide. What is the area of the board in square meters? Do not round your answer. Be sure to include the correct unit in your answer.
Answers
Given:
shape: rectangle
length: 1200 mm
width: 800 mm
Find: area in square meters
Solution:
First, let's convert the given dimensions to meters.
Conversion rule is 1 m = 1000mm. Let's convert the length first.
[tex]1200\operatorname{mm}\times\frac{1m}{1000\operatorname{mm}}=1.2m[/tex]Length = 1.2 meters
Now, let's convert the width.
[tex]800\operatorname{mm}\times\frac{1m}{1000\operatorname{mm}}=0.8m[/tex]Width = 0.8 meters
Now that we are done converting the dimensions of the board to meters, let's solve for the area. The formula is:
[tex]Area=length\times width\text{ }[/tex]Let's plug in the converted dimensions to the formula.
[tex]Area=1.2m\times0.8m=0.96m^2\text{ }[/tex]Therefore, the area of the board is 0.96 square meters.

Answers
Answer:
At the movie premiere, adult moviegoers enjoyed the movie more because only 25% did not like the movie whereas 68% of the teenager moviegoers did not like the movie.
First, let us get the percentage of adults that liked the movie.
It is said that 15 out of 20 adults liked the movie. We can get the percentage by dividing the number of adults who liked the movie by the total number of adults.
[tex]\frac{\text{ number of adults who liked the movie }}{\text{ total number of adults }}=\frac{15}{20}\times100=75\%[/tex]We will then find out the percentage of adults and teenagers that did not like the movie by subtracting the percentage that liked the movie from 100%
Adults who did not like the movie:
[tex]100\%-75\%=25\%[/tex]Teenagers who did not like the movie:
[tex]100\%-32\%=68\%[/tex]Here, we can conclude that:
At the movie premiere, adult moviegoers enjoyed the movie more because only 25% did not like the movie whereas 68% of the teenager moviegoers did not like the movie.
Determine the center and radius of the following circle equation:x2+y2−14x−10y−26=0x 2 +y 2 −14x−10y−26=0
Answers
To determine the center of the circle;
x² + y² - 14x - 10 y - 26 = 0
we have to make the above equation to be in the form;
(x-a)² + (x-b)² = r²
where (a,b) is the center of the circle and r is the radius of the circle
x² + y² - 14x - 10 y - 26 = 0
add 26 to both-side of the equation
x² + y² - 14x - 10 y - 26 + 26 = 0 + 26
x² + y² - 14x - 10 y = 26
x² - 14x +y² - 10y = 26

3 Find the co-ordinates of the point at which the gradient of the curve with equation y = 3x² has gradient 18.
Answers
The co-ordinates of the point at which the gradient of the curve y = 3x² is 18 are (3, 27).
Here we are given the equation of a curve as- y = 3x²
The gradient of a curve can be found out by differentiating it with respect to the independent variable. Thus, the gradient here will be dy/dx.
dy/dx = 6x
Thus the gradient of the curve is 6x.
Further, we are given that the gradient value is 18. thus, the value of x at gradient = 18 will be-
6x = 18
x = 18/6
x = 3
Substituting this in the equation of the curve, we can find the value of y as follows-
y = 3*3²
y = 3*9
y = 27
Thus, the co-ordinates of the point at which the gradient of the curve y = 3x² is 18 are (3, 27).
