Let the vector \mathbf{v}v have an initial point at (1, -2)(1,−2) and a terminal point at (0, 0)(0,0). Plot the vector \mathbf{v}v and afterwards follow the guided steps to analyze the vector.
Given that the initial point of the vector is (1,-2) and the termination point of the vector is (0,0).
So, the tail of the vector is at point (1,-2) and the head of the vector is at (0,0). The vector, [tex]\vec{v}[/tex], has been shown in the figure.
The magnitude of the vector:
[tex]|\vec{v}|=\sqrt{(1-0)^2+(-2-0)^2}=\sqrt{1+4}=\sqrt{5}[/tex]
The direction of a vector is the angle made by a vector with the positive direction of the x-axis.
From the figure, [tex]\theta = 180 \degree\tan ^{-1} \left|\frac {0-(-2)}{0-1}\right|[/tex]
[tex]\theta = 180 ^{\circ} - \tan^{-1}(2) = 180 ^{\circ} - 63.43^{\circ}[/tex]
[tex]\theta =116.57 ^{\circ}[/tex]
Hence, the required vector having a magnitude [tex]\sqrt {5}[/tex] and direction [tex]116.57 ^{\circ}[/tex] has been shown in the figure.
What is the slope of the line passing through the points (0, 4) and (-8, -1)?
Enter your answer in the box.
Answer:
0.625
Step-by-step explanation:
Given the points :
(0, 4) and (-8, -1)
x1 = 0 ; y1 = 4
x2 = - 8 ; y2 = - 1
Slope, m = rise / run
Rise = y2 - y1 = - 1 - 4 = - 5
Rise = x2 - x1 = - 8 - 0 = - 8
The slope, m = - 5 / - 8
Slope, m = 0.625
given a-2b=8, 4a+3b= 21; prove b= -1
please give a step by step answer
Answer:
Step-by-step explanation:
We can solve this with some pretty simple substitution
First write that a=2b+8
and our reasoning for this is that we added 2b from the first equation
Then write
4(2b+8)+3b=21
After we figured out what A was in the previous part we are able to substitute that into our other equation
Then you solve for b from here
8b+32+3b=21
11b=-11
b= -1

Answer:
The slope is 2
Step-by-step explanation:
Pick two points and plug into this equation: y2-y1/x2-x1
(-3,2) and (-1,6)
2-6/-3-(-1)=-4/-2= 2
Answer:
The slope of the linear function is 2
Step-by-step explanation:
Calculating the Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The table shows four points: (-3,2), (-1,6), (1,10), and (3,14). To find the slope on the line passing through them we only need two, for example (-3,2), (-1,6):
[tex]\displaystyle m=\frac{6-2}{-1+3}[/tex]
[tex]\displaystyle m=\frac{4}{2}=2[/tex]
Any other pair of points should give the very same value for the slope. Use (1,10), and (3,14):
[tex]\displaystyle m=\frac{14-10}{3-1}[/tex]
[tex]\displaystyle m=\frac{4}{2}=2[/tex]
Thus, the slope of the linear function is 2

What is the slope of the line?
Answer:
=4/1 or 4
Step-by-step explanation:
Remember Rise/Run
also remember this formula:
y2-y1/
x2-x1
Your coordinates are: (-2, 1) (-3, -3)
-3-1/
-3-(-2) = -4/-1 or 4
Two negatives cancel out and make it a positive.

Step-by-step explanation:
A and B are complementary angles. If A = (x + 9) and m B = (7x – 15)° then find the measure of B.
Answer:
[tex]coplementary \: angles \: = 90° \\ (x + 9)° + (7x - 15)° = 90° \\ (8x - 6)° = 90° \\ 8x = 90 + 6 \\ 8x = 96° \\ x = 12\\ angle \: B. = ((7 \times 12)- 15) \\ = 69°[/tex]
how to simplify (4x + 3) - (6x - 2) + (3x + 5)
Answer:
It is simplified as x + 10.
Step-by-step explanation:
Convert the negative sign for the second parentheses equation to -6x + 2. Your equation should now look like this 4x + 3 -6x + 2 + 3x + 5. Combine the 3 x value terms and the 3 non-value terms together to get your simplified answer which is x + 10.
Find the value of X in the measure of angle 2.
Answer:
x = 11, ∠ 2 = 146°
Step-by-step explanation:
∠ 2 and 146° are corresponding angles and are congruent, then
∠ 2 = 146°
Thus
13x + 3 = 146 ( subtract 3 from both sides )
13x = 143 ( divide both sides by 13 )
x = 11

Answer: $6,120
Step-by-step explanation:
There are 15 fruits in each basket.
The store shipped 3,825 fruits, to find the number of baskets of fruits shipped you have to divide 3,825 by 15.
3,825 ÷ 15 = 255
Each basket costs $24 so to find the cost of 255 baskets, you multiply 255 by 24.
$24 × 255 = $6,120
Leona earned $6,120 from the gift baskets sold.

Can someone help me calculate angles? P2
Answer:85
Step-by-step explanation: In this problem you are trying to find the missing angle of a line. In a line all angles have to add up to 180 so what you wanna do first is add 55 and 40 which gives you 95. Next, you wanna subtract 95 from 180 which will give you 85. Now you know the missing angle.

The way I learned it was that if they dont have the same variables dont touch them, so what I did was multiply the like numbers (2 and 5). Why are they alike? Because they don't have a variable! I then just put the X sign there to show that there is no other way to multiply this. If it where addition, it would be 10+a so that would equal 10a.

Answer:
x ≈ 31.0°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanx = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{9}{15}[/tex], then
x = [tex]tan^{-1}[/tex] ([tex]\frac{9}{15}[/tex] ) ≈ 31.0° ( to 1 dec. place )

Answer:
-1 4/5, -1.7, -1 1/10, -1.
Step-by-step explanation:
We convert all of these to tenths. -1 4/5 becomes - 1 8/10. -1.7 becomes -1 7/10. -1 1/10 is already in tenths and -1 is a whole number. When putting these from least to greatest, remember that the bigger the negative, the less the number is.

In a bag there are blue sweets and red sweets.
The ratio of blue sweets to red sweets is 4:9
What fraction of the sweets are blue?
Answer:
9/4
Step-by-step explanation:
9 out of 4 are blue, just flip the ratio.
Answer:
4/13
Step-by-step explanation:
A ratio can be added up to find the denominator, and using that information, you can do 4+9=13. Then in order to find the blue sweets which are the 4 part, we just need to make it numerator to get 4/13.
