Problem 2: Vector v has initial point (4, 3) and terminal point (-7, 9). Write v as a linear combination of the standard unit vectors i and j.

Answers

Answer 1

We have

v = (-7, 9) - (4, 3) = (-7 - 4, 9 - 3) = (-11, 6)

which as a linear combination of the i and j unit vectors is

v = -11i + 6j

Answers

Step-by-step explanation:

what do you need to do ? draw the line ? or find some intercepts on the x- or y-axis ? or ?

in any case it is important to bring this into the typical line equation form :

y = ax + b

so,

-4x = -1 + y

we leave y alone on one side

y = -4x + 1

to draw the line you need 2 points.

so, let's find some.

one typical choice is x = 0.

then y = -4×0 + 1 = 1

so, P1 = (0, 1)

and then e.g. let's pick x = 1

then y = -4×1 + 1 = -4 + 1 = -3

so, P2 = (1, -3)

there you have it

mark the two points on the coordinate graph, then take a ruler and draw the line all the way from top left to bottom right so that it goes through the two points.

d/3 =13 what is d and explain why its d.

Answers

Answer: d = 39

Solve:

Given

d / 3 = 13

In order to get the value of d, we need to isolate d, which means we should multiply 3 on both sides to delete the 3 on the left-hand side

d / 3 × 3 = 13 × 3

d = 39

Check:

Left-hand side = d / 3 = 39 / 3 = 13

Right-hand side = 13

13 = 13

Hope this helps!! :)

Please let me know if you have any questions

Answer:

39

Step-by-step explanation

so d ÷ 3 = 13

first we want to change these numbers into a fraction so

d ÷ 3 = [tex]\frac{d}3}[/tex]

13 is whole but we can still display it as 13÷1 =[tex]\frac{13}{1}[/tex]

line these up like this

[tex]\frac{d}{3} \frac{13}{1}[/tex]

now cross multiply the numbers that always line up diagonally so 13 and 3

13x3=39

next divide that answer by the number diagonal to the unknwon so 39÷1 = 39

that means d = 39

What is the height of the FlagPole?

Answers

26² - 10² = 676 - 100 = 576

√576 = 24

The height of the Flagpole is, 24 feet.

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

The base length = 10 ft

And, The hypotenuse length = 26 ft

Now, Let height of the Flagpole = x

So, By Pythagoras theorem we get;

⇒ Hypotenuse² = Base² + Perpendicular²

⇒ 26² = 10² + x²

⇒ 676 = 100 + x²

⇒ x² = 676 - 100

⇒ x² = 576

⇒ x = √576

⇒ x = 24 feet

Thus, The height of the Flagpole = 24 feet

Answers

Answer:

Final equation: y = -7x -19

Step-by-step explanation:

You are looking for slope intercept correct?

Formula: y = mx + B

Y = y-value of point ( coordinates )

M = slope

X = x - value of point ( coordinates )

B = Y - intercept

Equation:

2 = -7(-3) + B

2 = 21 + B

-21 = -21 = B

------------------

-19 = B

Final equation: y = -7x -19

Unless if it asks you to plug back the numbers for anything else then you do that but this is how you get slope intercept.

Replace x and y’all with the point and solve the equations

1. 2(0.5)+ 4(-6.75) = 1 + -27 = -26

This is true so is an answer.

2. Y = 0.5-7.5 = -7, -7 is not -6.75 so this is not true.

3. 2(-6.75) = 0.5 + 13

13.5 = 13.5

This is true so is also an answer.

4. -6.75 = 0.5(0.5) -7

-6.75 = 0.25-7

This is true so also an answer.

Answers are 1, 3 and 4

Answer:

Equation 1 and 4

Step-by-step explanation:

Point = (x,y) = (0.5,-6.75)

Hence,

x = 0.5 , y = -6.75

Equation 1:

2(0.5) + 4(-6.75) = -26

1 - 27 = -26

-26 = -26

This equation is true for the given point.

Equation 2:

-6.75 = 0.5 - 7.5

-6.75 ≠ -7

The equation is not true for the given point.

Equation 3:

2 (-6.75) = 0.5 + 13

-13.5 ≠ 13.5

The equation is not true for the given point.

Equation 4:

-6.75 = 0.5(0.5) - 7

-6.75 = 0.25 - 7

-6.75 = -6.75

This equation is true for the given point.

Find the midpoint of (4,5) & (2,2)

Answers

Answer:

&

Step-by-step explanation:

Answer:

[tex]\boxed {\boxed {\sf (3, \frac{7}{2}) \ or \ (3, 3.5)}}[/tex]

Step-by-step explanation:

The midpoint is the middle point of a line segment that bisects (splits into 2 equal parts) the line segment. When we calculate the midpoint, we basically find the average of the x-coordinate, then the average of the y-coordinates. The formula is:

[tex](\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the segment.

We are given the points (4,5) and (2,2). Match the value and the corresponding variable.

x₁= 4 y₁= 5 x₂= 2 y₂=2

Substitute these values into the formula.

[tex](\frac{4+2}{2} , \frac{5+2}{2})[/tex]

Solve the numerators.

X-coordinate: 4+2= 6 Y-coordinate: 5+2=7

[tex](\frac{6}{2}, \frac{7}{2})[/tex]

Divide.

[tex](3, \frac{7}{2}) \ or \ (3, 3.5)[/tex]

The midpoint of the line segment is (3, 7/2) or (3, 3.5).
