Answer:
<1 ,1>..., square root of two
Step-by-step explanation:
Component of vector PQ...,
; Q - P...where you subtract the x coordinate of Q by the x coordinate of P and the same for the y coordinate
; <(6-5),(9-8)>
; < 1,1 >
And the magnitude of PQ...,
;square root of( 1^2 + 1^2 )
;square root of 2
Final answer:
The component form of vector PQ is <1, 1>, and the magnitude is the square root of 2, thus the correct answer is <1, 1>, square root of 2.
Explanation:
To find the component form and magnitude of vector PQ, we calculate the difference in the x-coordinates and the y-coordinates of points P and Q. The component form of a vector is obtained by subtracting the coordinates of the initial point from the coordinates of the terminal point. In this case, the initial point is P(5, 8) and the terminal point is Q(6, 9).
The component form of vector PQ is therefore:
Vector PQ = (Qx - Px, Qy - Py)
Vector PQ = (6 - 5, 9 - 8)
Vector PQ = <1, 1>
Next, to find the magnitude of vector PQ, we use the Pythagorean theorem, which is the square root of the sum of the squares of the components:
Magnitude of PQ = √(1^2 + 1^2)
Magnitude of PQ = √(2)
Magnitude of PQ = √2
Therefore, the correct answer is <1, 1>, √2.

What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).
Parts of an EquationThere are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.
Given:
3x = 6x - 2
3x-6x= -2
-3x= -2
x= -2/-3
x= 2/3
Hence, the value of x is 2/3

A ladder leaning against the side of a building touches the building at a point 12 meters from the ground. If the foot of the ladder is 18 meters from the base of the building, what is the slope of the ladder?
Answer:
The slope of the ladder to the building is 2/3
Step-by-step explanation:
* Lets explain how to find the the slope of the ladder
- A ladder leaning against the side of a building touches the building
at a point 12 meters from the ground
* That means the height of the ladder (h) from the ground is 12 m
- The foot of the ladder is 18 meters from the base of the building
* That means the horizontal distance (d) on the ground between the
ladder and the building is 18 m
- The slope of the ladder (m) , the height of the ladder (h) and the
horizontal distance on the ground from the base of the ladder to
the base of the building (d) can form a right triangle
∵ The slope of the ladder = the vertical distance/horizontal distance
∵ The vertical distance h is 12 meters
∵ the horizontal distance d is 18 meters
∴ The slope of the ladder [tex]m=\frac{12}{18}=\frac{2}{3}[/tex]
∴ The slope of the ladder to the building is 2/3
Answer:
2/3
Step-by-step explanation:
Its just as easy as it looks. Its 12/18, or Rise 12 and Run 18.
Solving would get you 2/3, so your slope is 2/3

Give an equation for a line perpendicular to the line y=0. Is there more than one such line? Explain.
Check the picture below.
sure, since y = 0 is a line, in essence the x-axis really, that goes to infinity, so we can draw an infinite amount of perpendicular lines on it all the way.
The equation for a line perpendicular to the line y=0 is x=a, where a is the x-coordinate of the point where the line intersects the x-axis. There are infinitely many lines that are perpendicular to the line y=0. For example, the line x=3.
Explanation:The equation for a line perpendicular to the line y=0 is simply the equation for a vertical line passing through any point on the x-axis. A vertical line is defined by the equation x = a, where a is the x-coordinate of the point where the line intersects the x-axis.
Since the line y=0 is also the x-axis, any vertical line passing through a point on the x-axis will be perpendicular to it. Therefore, there are infinitely many lines that are perpendicular to the line y=0.
For example, the equation for a line perpendicular to y=0 passing through the point (3,0) would be x=3.

Lauren will visit both the park and the library on the same day again after 30 days. This is because the least common multiple (LCM) of 3 and 10 is 30.
Explanation:The subject of this question is Mathematics, particularly dealing with the concept of least common multiple (LCM). The question is asking when will Lauren visit the park and the library on the same day again. Given that Lauren goes to the park every 3 days and the library every 10 days, the day when she'll do both again is the least common multiple of 3 and 10.
The least common multiple (LCM) is the smallest multiple that is exactly divisible by every member of a set of numbers. In this case, we need to determine the LCM of 3 and 10. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ... The multiples of 10 are 10, 20, 30, 40, .... As we can see, the smallest number that appears in both lists is 30. Therefore, Lauren will visit both the park and library on the same day again after 30 days.

A point, beginning at (0,0), undergoes the following composition of translation. Write an ordered pair for the points final position. T<5,-7> and then T<-6,2>
Answer:
(-1,-5)
Step-by-step explanation:
Starting at (0,0), we perform the first translation:
T<5,-7> implies that we move the point 5 units to the right (in the x (horizontal) direction), and 7 units DOWN in the y <vertical) direction.
From there we do the second translation: T<-6,2>
which means: 6 units to the left (in the horizontal direction) which takes us to "-1" for the x value, and 2 units up (vertical) which takes us to -5 for the y value.
Therefore the new location is (-1,-5)
Lines p, q, and r all pass through point (-3,4). Line p has slope 4 and is perpendicular to line q. Line r passes through Quadrants 1 and Quadrants 2 only. Write an equation for each line. Then graph the three lines on the same coordinate plane.
This response provides the equations for three lines that all pass through the point (-3, 4). Line p's equation is identified as y = 4x + 16, the equation for perpendicular line q is y = -1/4x + 5.75, and the equation for the horizontal line r, which only traverses Quadrants 1 and 2, is y = 4.
Explanation:The subject of your question is related to
Algebra of Straight Lines
, specifically, writing equations of lines that pass through a specific point (-3,4), and have certain slopes or orientations.
Let's start by examining line p which passes through the point (-3,4) and has a slope of 4. Using the point slope form of linear equation, we have y - y1 = m(x - x1). Substituting the given values, we get y - 4 = 4(x + 3) which simplifies to y = 4x + 16. This is the equation for line p.
The line q is perpendicular to line p, so its slope is the negative reciprocal of the slope of p, which is -1/4. Using point slope form of linear equation and substitifying the slope and point, we get y - 4 = -1/4(x + 3) which simplifies to y = -1/4x + 5.75. This is the equation for line q.
The line r is a little bit tricky since it's only mentioned to pass through Quadrants 1 and 2. This implies that the slope of r is 0, making line r horizontal. Because it passes through y=4, its equation is simply y = 4.

A roll of material is (x + 2) metres wide. Annie buys (x + 3) metres of the material and Bronwyn buys 5 metres of the material.
a) Write an expression, in terms of x, for the area of each piece of material purchased.
b) If Annie has bought more material than Bronwyn, write an expression for how much more she has than Bronwyn.
c) Factorise and simplify this expression.
d) Find the width of the material if Annie has 5m^2 more than Bronwyn.
e) How much material does each person have? Explain.
The problem involves determining the area of material purchased, comparing the quantities, and solving for the width given certain conditions. After setting up and solving the equations, it was found that the width of the material is 3 metres and the total amounts of material purchased by Annie and Bronwyn are 4 and 15 square metres respectively.
To solve the problems related to the area of material purchased by Annie and Bronwyn, follow these steps:
Area of material: Given the width of the material is (x + 2) metres, Annie buys (x + 3) metres long and Bronwyn buys 5 metres long. The area for each piece of material purchased is the product of the width and length. So, Annie's material area is (x + 2)(x + 3) square metres, and Bronwyn's material area is 5(x + 2) square metres.
More material: To express how much more material Annie has than Bronwyn, subtract Bronwyn's area from Annie's area, which gives us ((x + 2)(x + 3) - 5(x + 2)) square metres.
Factorisation: The expression for how much more material Annie has than Bronwyn can be factorized as (x + 2)(x - 2) square metres after simplifying.
Width of material: If Annie has 5 square metres more material than Bronwyn, we solve the equation (x + 2)(x - 2) = 5. Solving this quadratic equation gives x = 1, the width of the material is therefore 3 metres.
Total material: With x = 1, Annie purchases 4 square metres (since 3 x 1 + 3) and Bronwyn purchases 15 square metres (since 5 x 3). So, Annie has 4 square metres of material and Bronwyn has 15 square metres.

A store sells 4 cans of fruit cocktail for $10.What is the price of 7 cans of fruit cocktail?
Answer:
17.5
Step-by-step explanation:
so 4 cans is 2.5$ each so i did 2.5 times 7 to see how much it would be for 7 cans
To find the cost of 7 cans of fruit cocktails, you first determine the price per can at $2.50 by dividing the cost for 4 cans ($10) by 4. Multiplying the price per can by 7 gives the total cost, which is $17.50.
Explanation:To find the price of 7 cans of fruit cocktails when 4 cans are sold for $10, we need to calculate the price per can and then multiply by the desired number of cans.
Step-by-step calculation:
First, determine the price per can by dividing the total price by the number of cans: 4 cans for $10 results in $10 ÷ 4 = $2.50 per can.Next, multiply the price per can by the number of cans desired: 7 cans × $2.50 per can = $17.50.Therefore, 7 cans of fruit cocktails will cost $17.50.
How much interest is earned on an investment of $12,000 at 2.9% compounded daily for eight years
Answer:
$3,113,34
Step-by-step explanation:
The formula for calculating compound interest is
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Where
A=the future total value, i.e, the money you will have after t years.
P=the initial deposit.
r=the annual interest rate.
n=the number of times that interest is compounded per year.
t=the number of years the money is saved.
In our case
A is unknown and we will have to calculate it with the formula.
P=$12,000
r=2.9%=0.029
n=365 because the interest is compounded daily and there are 365 days in a year
t=8 years
Applying the formula we get
[tex]A=12,000(1+\frac{0.029}{365})^{365\times8}[/tex]
[tex]A=12,000(1+\frac{0.029}{365})^{2,920}[/tex]
[tex]A=12,000(1.000079)^{2,920}[/tex]
So A=15,113.336
This is the amount of money you would have after 8 years.
Subtracting the initial deposit from this amount we obtain the interest earned I
I=15,113.336-12,000=3,113.336
Rounded to the nearest hundreth
I=$3,113,30

solve for x: x² - 14x + 49/x² - 49 = 3/17
Answer:
x = 10
Step-by-step explanation:
Begin by factorising the numerator/ denominator of the left side
x² - 14x + 49 = (x - 7)² ← perfect square
x² - 49 = (x - 7)(x + 7) ← difference of squares
Thus left side becomes
[tex]\frac{(x-7)^2}{(x-7)(x+7)}[/tex] → x ≠ ± 7
Cancel (x - 7) on numerator/denominator, leaving
[tex]\frac{x-7}{x+7}[/tex]
Returning to the equation, that is
[tex]\frac{x-7}{x+7}[/tex] = [tex]\frac{3}{17}[/tex] ( cross- multiply )
17(x - 7) = 3(x + 7) ← distribute both sides
17x - 119 = 3x + 21 ( subtract 3x from both sides )
14x - 119 = 21 ( add 119 to both sides )
14x = 140 ( divide both sides by 14 )
