Answer:
m= -4/5
Step-by-step explanation:
Use the slope formula to find the slope m .
Slope formula:
m=slope
(x_1, y_1) =coordinates of first point in the line
(x_2, y_2)=coordinates of second point in the line
m = (y2 -- y1) / (x2 -- x1).

what The definition of dilration in Math
Answers
A dilation is a function from a metric space into itself that satisfies the identity for all points, where is the distance from to and is some positive real number. In Euclidean space, such a dilation is a similarity of the space. Dilations always change the size but not the shape of object or figure.
Answer: Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

solve using gaussian elimination and show ur work
2y + z = -8
x - 2y - 3z = 0
-x + y + 2z = 3
Answers
Add the last two equations to eliminate x :
(x - 2y - 3z) + (- x + y + 2z) = 0 + 3
- y - z = 3
y + z = -3
Subtract this from the first equation to eliminate z, then solve for y :
(2y + z) - (y + z) = -8 - (-3)
y = -5
Plug this into the first equation to solve for z :
2(-5) + z = -8
z = 2
Plug both of these into either the second or third equations to solve for x :
x - 2(-5) - 3(2) = 0
x = -4

in 2005 the san francisco bay times reported on a poll in new zealand that found that new zealanders opposed the nation`s new gay-inclusive civil-unions law by a 3-1 ratio. This poll was a call-in poll that cost $1 to participate in, The san francisco bay times article also reported that a scientific polling organization found that new zealanders favor the law by margin of 56.4% to 39.3%. explain to someone who knows no statistics why the two polls can give such a widely differing results and which poll is likely to be be more reliable
Answers
Answer:
In the given data reported poll on a new Zealand.
The article reported that new Zealanders favors the law by a margin of 56.4% to 39.3%
These difference in results in which poll is likely to be more reliable is that the San Francisco Bay Times utilized the Voluntary Response technique ( Voluntary reaction strategy is self chosen technique, it's kin decision whether to give reaction or not). So the two surveys can give such generally varying outcomes.
Thus their survey results can't be viewed as dependable

Answer:
El área de un rectángulo de largo L y ancho A es: L*A.
El área de un triangulo de alto H y base B es: H*B/2.
Ahora veamos las tres figuras:
Rectángulo amarillo:
Largo = 40m
Ancho = 45m
Área = 40m*45m = 1800 m^2
Rectángulo blanco:
Largo = 40m
Ancho = 35m
Área = 40m*35m = 1400m^2
Triangulo azul:
Base = 35m
Alto = 50m
Área = 35m*50m/2 = 875m^2
Area total = 1800 m^2 + 1400m^2 + 875m^2 = 4075m^2

The rock travels 8.2x² meters higher on the Moon than on Earth.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The height above the surface of the Moon is given by g(x) = -1.6x² + 10x + 1.5.
The height above the surface of the Earth is given by f(x) = -9.8x²
+ 10x + 1.5.
To find the difference in height between the two, we can subtract the Earth equation from the Moon equation:
g(x) - f(x) = (-1.6x² + 10x + 1.5) - (-9.8x² + 10x + 1.5)
Which simplifies to:
g(x) - f(x) = 8.2x²
Therefore, the rock travels 8.2x² meters higher on the Moon than on Earth.

3 sec = 36 feet
6 sec = 72 feet
9 sec = 108 feet
(b)
After 3 seconds, the elevator is 144 feet above the first floor
After 6 seconds, the elevator is 108 feet above the first floor
After 9 seconds, the elevator is 72 feet above the first floor
(c) It takes 15 seconds for the elevator to get to the first floor
(d) The basement floor is 48 feet below the first floor
Step-by-step explanation:
31 (a) explanation:
An elevator is 180 feet above the first floor.
Each second, it descends 12 feet.
So the elevator's change in height each second is a decrease of 12 feet towards the first floor.
31 (b) explanation:
If the elevator goes down 12 feet, towards the first floor, in 1 second then;
After 3 seconds it will be 180 feet - 3(12) feet = 144 feet above the first floor
After 6 seconds it will be 180 feet - 6(12) feet = 108 feet above the first floor
After 9 seconds it will be 180 feet - 9(12) feet = 72 feet above the first floor
31 (c) explanation:
If the elevator is 180 feet above the first floor and it takes 1 second to descend 12 feet,
Then it will take: × 1 second = 15 seconds reach the first floor.
31 (d) explanation:
From the first floor it takes 4 seconds to reach the basement floor
Therefore the basement floor is × 12 feet = 48 feet below the first floor

A cuboid measures 60cm by 40cm by 20cm.
a) Find the area of the largest face in cm 2 and m 2 .
b)Calculate the volume of the cuboid in cm 3 and m 3 .
Answers
Answer:
a) The area of the largest face = 2400 cm², The area of the largest face = 0.24 m²
b) The volume of the cuboid = 48000 cm³, The volume of the cuboid = 0.048 m³
Step-by-step explanation:
The volume of any cuboid = L × W × H, where
L is its length
W is its width
H is its height
∵ A cuboid measures 60 cm by 40 cm by 20 cm.
→ Assume that L = 60 cm, W = 40 cm, H = 20 cm
a)
∵ The largest face is the face who has the largest dimensions
∵ L and W are the largest dimensions
∴ The area of the largest face = L × W
∴ The area of the largest face = 60 × 40
∴ The area of the largest face = 2400 cm²
∵ 1 cm = 1/100 m
∴ 1 cm² = (1/100)² m² = 1/10000 m²
∴ The area of the largest face = 2400 × 1/10000
∴ The area of the largest face = 0.24 m²
b)
∵ The volume of the cuboid = L × W × H
∴ The volume of the cuboid = 60 × 40 × 20
∴ The volume of the cuboid = 48000 cm³
∵ 1 cm = 1/100 m
∴ 1 cm3 = (1/100)³ m³ = 1/1000000 m³
∴ The volume of the cuboid = 48000 × 1/1000000
∴ The volume of the cuboid = 0.048 m³
