Answer:
these problems are always tough b/c they want you to translate normal thinking into math jargon :D soooo....
Step-by-step explanation:
they use the point slope formula... which looks like
y = [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])
where ([tex]x_{1}[/tex] , [tex]y_{1}[/tex] ) are the x , y coordinates of some point you're given.. sooo
they give us two points.. so we can put either one of those into the formula.. but we also have to find m.... or the slope ... to find m.. use the slope equation of
m = ( [tex]y_{2}[/tex] - [tex]y_{1}[/tex] ) / ( [tex]x_{2}[/tex] - [tex]x_{1}[/tex] )
call either point P1 and P2 ... i'll pick the top point as P1 and bottom as P2
then
m = ( -3 -1 ) / ( 1 - 3 )
m = -4 / -2
m = 2 ( yay :) )
now use either point and plug it into the point slope formula, i'll use P1
y - 1 = 2(x-3) ( this is the answer they are looking for )

You toss two number cubes. If a sum of 7 or 11 comes up, you get 7 points, if not you lose 2 points.
The probabilities for each of the sums is:
P(2) = 1/36 P(3) = 1/18 P(4) = 1/12 P(5) = 1/9
P(6) = 5/36 P(7) = 1/6 P(8) = 5/36 P(9) = 1/9

What is the equation of the midline for the function f(x)? f(x)=1/2cos(x)+5
Answers
Answer: y=5
Step-by-step explanation:
At x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation.
Is the cos graph symmetrical?
The function cos x is even, so its graph is symmetric about the y-axis.
According to the question
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex]
as cos x is symmetric about y axis
So,
By plotting the graph
we can see that at point x = 0
y = 5.5 is the mid point of this equation
Hence, x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .

Answers
Answer:
[tex]\Huge\boxed{neither}[/tex]
Step-by-step explanation:
Parallel lines never touch and these lines intersect therefore these are not parallel lines
These lines may intersect but they do not create 90 degree angles which is essential for perpendicular lines and for those reasons the lines shown are not perpendicular lines
So we conclude that the lines shown are neither parallel lines nor perpendicular lines

A volleyball team played five games. In those games, the team won by 7 points, lost by 3, lost by 2, won by 4, and won by 9. What was the total amount of points from all five games
Answers
Answer:
The answer is "3"
Step-by-step explanation:
In essence, it represents the sum of all comments divided by the number of responses.
It implies scoring in the five games corresponds to a total of five results.
Scores :
7 points implies+ 7
lost by 3 implies- 3
lost by 2 implies - 2
won by 4 implies + 4
won by 9 implies + 9
Sum of all scores [tex]= 7 - 3 - 2 + 4 + 9 = 15[/tex]therefore
Its team has a total of 5 games[tex]= 5[/tex]
Measurement in scores in five games thus = sum of all scores/sum with the team played games [tex]=\frac{15}{5}= 3[/tex]
