Step-by-step explanation:
calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = N (- 5, 7 ) and (x₂, y₂ ) = P (- 1, 3 )
d = [tex]\sqrt{(-1-(-5))^2+(3-7)^2}[/tex]

What is unitary method ?Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.
Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.
Imagine that your square is made up of smaller unit squares.
The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.
To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured
According to our question-
The velocity in this problem is the average walking speed, hence the distances in the table are calculated by dividing the time in the same row by the velocity.
The velocity is reported as follows for the first row:
2.5 miles per hour is equal to v = 0.5/(12/60) = 0.5/0.2.
The minutes are split by 60 because the time is in hours.
The velocity is stated as follows for the second row:
1.5 x 4/3 divided by 45/60 equals 2 miles per hour, or v.
The velocity is given as follows for the third row:
v = 0.75 x 4 x (15/60) = 4 miles per hour.
Hence, 4 miles per hour.

Find the x- and y-intercepts of the graph of x + 4y = 20. State each answer as an I refer or an improper fraction in simplest form.
Answers
x-intercept: 20
y-intercept: 5
To find the x- and y-intercepts of the graph of the equation x + 4y = 20, we need to solve the equation for x and y, respectively.
First, to find the x-intercept, we need to set y equal to 0 and solve for x. This gives us the following equation:
x + 4(0) = 20
x = 20
Therefore, the x-intercept is (20, 0).
Next, to find the y-intercept, we need to set x equal to 0 and solve for y. This gives us the following equation:
0 + 4y = 20
4y = 20
y = 5
Therefore, the y-intercept is (0, 5).

A marble is launched from a ledge at a height of 2.8 m with a velocity of 3.27 m/s. How far from the ledge will the marble land

All objects fall at the same rate in a vacuum as long as the only force acting on them is gravity.
How height is the ledge from the ground?King employs a first person narrator and opens with the protagonist, a retired pro tennis star named Stan Norris, in the clutches of a wealthy, A horizontal projection forming a narrow shelf on a wall. A ledge is created when the working length can no longer be negotiated and the original pathway of the canal has been lost.The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.Hence, the height of the ledge from the ground is 1.25m.
3.27m/s
Given parameters:
Initial velocity = 3.27m/s
Height of fall = 2.8m
Unknown:
Final velocity = ?
To solve this problem, we have to look at our given parameters and compare to the appropriate motion equation.
we have been given; u (initial velocity) and height of fall (h)
Since this body falls under acceleration due to gravity, g = 9.8m/s²
Now, we use;
V² = U² + 2gh\
where V is the final velocity
Input the parameters and solve;
V² = 3.27m/s + (2 x 9.8 x 2.8)

How to find the volume of a cuboid?We are given that the volume of water in a rectangular, in-ground, swimming pool is; V(x) = x³ + 11x² + 24x
where;
V(x) is the volume in cubic feet when the water is x ft high
1) V(x ) =x³ + 11x³ + 24x
V(x) is the volume in cubic feet when the water is x ft high
Factorizing the polynomial into its' factors gives;
V(x) = x(x² + 11x + 24)
V(x) = x(x + 8)(x + 3)
The water is x ft high and so the dimensions of the base of the pool are (x + 3) and (x + 8)
2) We want to find the volume of the pool when x = 3 ft. Thus;
V(3) = 3(3 + 8)(3 + 3)
V(3) = 3 (11)(6)
V(3) = 198 ft³
3) If the volume is 100 ft³ of water, the height x is calculated as;
x(x + 8)(x + 3) = 100
Solving for x gives us;
x = 2 ft
4) If maximum capacity of the pool is 520 ft³, then the maximum depth is;
x(x + 8)(x + 3) = 520

(b) Find the value of k such that L1 and L2 are perpendicular.
This question is related to Linear functions, Answers: (a) k = -4, (b) k=1. Someone pls tell me how to get there though
Answers
Answer:
see explanation
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(a)
given the equation of L1 is
2x - y = 3 ( subtract 2x from both sides )
- y = - 2x + 3 ( multiply through by - 1 )
y = 2x - 3 ← in slope- intercept form
with slope m = 2
• Parallel lines have equal slopes
then slope of L2 is m = 2
given the equation of L2 is
kx + 2y = 3 ( subtract kx from both sides )
2y = - kx + 3 ( divide through by 2 )
y = - [tex]\frac{k}{2}[/tex] + [tex]\frac{3}{2}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{k}{2}[/tex]
since slope of L1 and L2 are equal, both 2 , then
- [tex]\frac{k}{2}[/tex] = 2 ( multiply both sides by 2 to clear the fraction )
- k = 4 ( multiply both sides by - 1 )
k = - 4
----------------------------------------------
(b)
given the slope of a line is m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]
Then
for L2 to be perpendicular to L1
- [tex]\frac{k}{2}[/tex] = - [tex]\frac{1}{2}[/tex] ( multiply both sides by - 1 )
[tex]\frac{k}{2}[/tex] = [tex]\frac{1}{2}[/tex] , thus
