what is the distance between points v (3,3) and w (-2,-3) round to the nearest tenth if necessary
Answers
Answer:
7.81 u
Step-by-step explanation:
Given :-
Two points (3,3) and (-2,-3) is given to us.And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,
[tex]:\implies[/tex] D = √{(x2-x1)² + (y2-y1)²}
[tex]:\implies[/tex] D =√[ (3+2)² +(-3-3)²]
[tex]:\implies[/tex] D =√[ 5² +6²]
[tex]:\implies[/tex] D =√[ 25 +36]
[tex]:\implies[/tex] D = 61
[tex]:\implies[/tex] D = 7.81
Hence the distance between the two points is 7.81 units .classify a triangle whose side lengths are 8, 16, and 18

horizontal line:
vertical line:
Answers
Answers:
Horizontal Line: y = 5
Vertical Line: x = 8
=================================================
Explanation:
All horizontal lines are of the form y = k, for some constant k. We want the horizontal line to pass through (8,5), meaning every point on this horizontal line must have y coordinate 5. Therefore, y = 5 is the equation of the horizontal line. Two such points on this line are (1, 5) and (8, 5). All that matters is the y coordinate is 5. The x coordinate can be anything you want. The slope of any horizontal line is 0.
Flipping things around, all vertical lines will have the x coordinate of each point be the same value. Draw a vertical line through (8,5) and note how each point has x coordinate of 8. Two such points are (8,1) and (8,5). Therefore, the equation of the vertical line is x = 8. The y coordinate can be any value you want. The slope of any vertical line is undefined. Unlike the horizontal line, we cannot write this equation in slope intercept form (namely because the slope isn't defined).

Answers
Answer:

Step-by-step explanation:
We know the value of cos 360° is always equal to 1.
Answer:
cos(360 + x) = cos x
Proof:
cosine identity:
cos(x + y) = cosxcosy - sinxsiny
or
cos(360 + x) = cos360cox - sin360sinx
but
cos360 = 1 and sin360 = 0
Therefore,
cos(360 + x) = cos x

Martin has a combination of 33 quarters and dimes worth a total of $6. Which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, Martin has?
q + d = 6 25q + 10d = 33
q + d = 6 0.25q + 0.1d = 33
q + d = 33 25q + 10d = 6
q + d = 33 0.25q + 0.1d = 6
Answers
Answer:
q + d = 33 0.25q + 0.1d = 6 Option D
Step-by-step explanation:
The system of linear equation that can be used to find the number of quarters, q, and the number of dimes, d, Martin has is as follows:
q + d = 33
0.25q + 0.1d = 6
Martin has a combination of 33 quarters and dimes worth a total of $6.
Therefore,
q = number of quarters
d = number of dimes
The linear equation can be represented below:0.1 dollars = 1 dime
0.25 dollars = 1 quarters
Therefore,
0.25q + 0.1d = 6
The quarters and dimes total 33. Therefore,
q + d = 33Therefore, the combined equation will be as follows:
q + d = 33
0.25q + 0.1d = 6

A company produces items in small batches the machinery needs to warm up before the atom can be produced the scatterplot shows the time needed to produce batches of different numbers of items
Answers
Answer: B. It takes about 20 minutes for the equipment to warm up
Step-by-step explanation:
Took the quiz
The true statement is 'It takes about 20 minutes for the equipment to warm up.'
The correct answer is an option (B)
What is the line of the best fit?"It is a line through data points that best expresses the relationship between those points."
What is y-intercept?"It is the points at which the graph of function intersects the Y-axis."
What is the slope of the line?"It is the change in y coordinate with respect to the change in x coordinate.""The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"What is the slope-intercept form of the line?"The slope-intercept form of the line, y = mx + b where m is the slope and b is the y-intercept."
For given question,
From the scatter plot, the line of the best fit passes through the points (3, 44) and (5, 60)
We find the slope of the line of best fit.
Let [tex](x_1,y_1)=(3,44),(x_2,y_2)=(5,60)[/tex]
Using slope formula,
[tex]\Rightarrow m=\frac{y_1-y_1}{x_2-x_1}\\\\\Rightarrow m=\frac{60-44}{5-3} \\\\\Rightarrow m=\frac{16}{2}\\\\ \Rightarrow m=8[/tex]
Also, the Y-intercept of the line of best fit is 20.
Using the slope-intercept form, the equation of the line of best fit would be,
y = 8x + 20
From this equation we can say that,
As the number of items in a batch is increases by 1, the production time increases by 8 minutes and it takes about 20 minutes for the equipment to warm up.
Therefore, the correct statement is 'It takes about 20 minutes for the equipment to warm up.'

At an ice carving competition, each carver starts with a block of ice with the dimensions shown. The block is
wrapped in a special reflective material to keep it from melting before the competition starts.
1.1 m
0.8 m
1.3 m
How much reflective material is needed to cover the block completely, without any overlaps?
Give an exact answer (do not round).
m?
Answers
So, what you are supposed to find here is the surface area of this rectangular prism. So the answer is 52 units of the special reflective material is needed.
Since total surface area of a rectangular prism = 2(lb + bh + hl)
Where l = length of the ice block
b = width of the ice block
h = height of the ice block
Now total surface area for the given dimensions = 2(4×2 + 2×3 + 3×4)
= 2(8 + 6 + 12)
