Answer:
0.2
Step-by-step explanation:
To calculate the scale factor of dilation, we need to divide the length of similar lines of parallelograms.
let the scale factor of dilation be 'x',
now,
x = 
= 
= 0.2
Answer: 0.8
Step-by-step explanation:
Add a decimal point, and then add a zero to 8. Divide 8.0 ÷ 10. Your answer is 0.8 because 0.8 goes into 8 10 times. There is no remainder.

Parabolas can shift up and down or left to right
Parabolas shifting left and right uses the formula of y=(x-a)^2 where a determined the amount it shifts.
E.g. y=(x-3)^2 moves right three units but if it was a +3 instead of -3, it moves three units to the left.
When parabolas move up or down, it uses y=mx^2+b (where b determines the amount it shifts)
If it is +10 , it moves ten units above but if it is -10 it moves ten units down
Answer:
23
Step-by-step explanation:
let the number be n then twice the number is 2n and 4 times the number is 4n
Then
2n = 4n - 46 ( subtract 4n from both sides )
- 2n = - 46 ( divide both sides by - 2 )
n = 23
The number is 23
Polar coordinates : r= - 5, α= - 180⁰.
Rectangular coordinates :
x=r*cosα = (-5)*cos (-180⁰)=(-5)*(-1)=5
y=r*sinα = (-5)*sin(-180⁰)=(-5)*0=0
So, <span>(-5, -180°) (polar coordinates) is the same as (5,0) (rectangular coordinates).</span>
