Find the distance between the pair of points.

Answers
Answer:
36.25 units
Step-by-step explanation:
Hi there!
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where two endpoints are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (19,−8) and (−14,−23):
[tex]d=\sqrt{(19-(-14))^2+(-8-(-23))^2}\\d=\sqrt{(19+14)^2+(-8+23)^2}\\d=\sqrt{(33)^2+(15)^2}\\d=\sqrt{1089+225}\\d=\sqrt{1314}\\d=36.25[/tex]
Therefore, the distance between the points is approximately 36.25 units.
I hope this helps!
Answer:36.25
Step-by-step explanation:distance between (x1, y1) and (x2,y2) is square root of (x2-x1)^2 + (y2-y1)^2. think of graph the distance between two points is the hypotenuse of a right angle triangle where the height is the difference of y and base is the difference of x
= square root of (19+14)^2 +(-23+8)^2= 36.25

A sum of money is shared amongst three friends, Shai, Toni and Mara in the ratio 6:5:9 respectively. If Toni received $160, how much money did Shai and Mara receive? HELLLLLLLLPPPPPPP
Answers
Answer:
$192 and $288Step-by-step explanation:
The ratio given:
Shai : Toni : Mara = 6 : 5 : 9Toni receives $160, which is 5 portions.
Each portion is:
$160/5 = $32Shai gets:
6*$32 = $192Mara receives:
9*$32 = $288Step-by-step explanation:
It is given
4x+3y=24
We can also write it as
3y=24−4x
y=324−4x
Substituting x=0 in the given equation
y=324−4(0)
So we get
y=324
By division
y=8
Substituting x=3 in the given equation
y=324−4(3)
So we get
y=312
BY division
y=4
an arrow is horizontally projected from the top of a tower with an initial velocity of 18m/s if it reaches the ground 7s later, calculate the height of the tower (take g=10m/s²)
Answers
Answer:
x[f]=at^2/2+v[i]t+x[i]
Brackets dennote a subscript.
You're given x[f], a, t,and v[i]. You can just plug in their values into the formula and solve for x[i]. The horizontal velocity is irrelevant, the height of the tower is the initial position of the arrow, and final position is gonna be when it reaches the ground,or 0.
6. How high must a crate be in order to hold 120 cubic meters if it has a base area of 24 square meters?
Answers
Answer:
height = 5 m
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = Ah ( A is area of base and h the height )
Here V = 120 and A = 24 , then
24h = 120 ( divide both sides by 24 )
h = 5
The height of the crate is 5 m

Answer:
3 ÷ 8
Step-by-step explanation:
1. A fraction has two parts: a numerator and a denominator. The numerator is the dividend (the number that is to be divided by the divisor), and the denominator is the divisor (the number that is divided into the dividend).
2. Given the information above, we know that 3 is the numerator, and 8 is the denominator. This means 3 ÷ 8 = 3/8.

Solve 5/(r-9)=8/(r+5)
Answers
Answer:
r = 32 1/3
Step-by-step explanation:
5/(r-9) = 8/(r+5)
cross multiply:
5 x (r + 5) = 8 x ( r - 9)
5r + 25 = 8r - 72
Add 72 to both sides:
5r + 97 = 8r
Subtract 5r from both sides
97 = 3r
Divide both sides by 3
r = 32 1/3
-Chetan K
Answer:
r = 32 1/3 or 97/3
Step-by-step explanation:
Step 1: Cross-multiply.
[tex]5*(r+5)=8*(r-9)[/tex] [tex]5r + 25 = 8r - 72[/tex]Step 2: Subtract 8r from both sides.
[tex]5r + 25 - 8r = 8r - 72 - 8r[/tex] [tex]-3r +25=-72[/tex]Step 3: Subtract 25 from both sides.
[tex]-3r + 25 - 25 = -72 - 25[/tex] [tex]-3r = -97[/tex]Step 4: Divide both sides by -3.
[tex]\frac{-3r}{-3}=\frac{-97}{-3}[/tex] [tex]r=\frac{97}{3}[/tex] [tex]r = 32\frac{1}{3}[/tex]Therefore, r = 32 1/3 or 97/3.

I've done the work but I need to know what my new coordinates will be
Here's the question
Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.
And then here is the answer:
You’re going to go left side three points and down five for every point on the graph (ABC) and once you do that label the ABC marks with an apostrophe like so; A’B’C’ for every time you change places
Answers
Answer:
A'(1, -9), B'(3, -5), C'(4, -8)Step-by-step explanation:
Use the given rule and find the coordinates as follows:
(x, y) → (x + 3, y - 5)A(-2, -4) → A'(-2 + 3, -4 - 5) = A'(1, -9)B(0, 0) → B'(0 + 3, 0 - 5) = B'(3, -5)C(1, -3) → C'(1 + 3, -3 - 5) = C'(4, - 8)The points are plotted, see the attached.
Answer:
Before I start, wouldn't you go right three times since it's x + 3 not x - 3. Id.k maybe I'm just slow.
Anyways, take your current points which are A(-2,-4), B(0,0), and C(1,-3) and apply the new mapping rule to them. For example: (-2 + 3, -4 -5), and that will give you A' (1,-9). If you do the same to the other two, you'd have B' (3,-5) and C' (4,-8).
I graphed A, B, C, and A', B', C' above for you.⤴⤴
