Answer:
A) LEngth of FG is 2 units
Step-by-step explanation:
Considering the diagram attached below.
Reflection of any polygon does not affects its length.
As it is given both polygons are reflection of each other so their sides are congruent.
AB ≅ EF = 3 units
BC ≅ FG = 2 units
CD ≅ GH = 2.2 units
DA ≅ HE = 3.2 units
X/40 = 7/20
40/20=2
x=7x2=14
14 red marbles
Hope this helps.
Answer: 1/3 = 33.3% or 33 ⅓%
1/9 = 11.1%
2/9 = 22.2%
8/9 = 88.9%
Step-by-step explanation:
Divide the numerator by the denominator. Multiply the quotient by 100 to change the decimal to a percentage.
All of these are repeating decimals, so it may be required to keep at least one decimal place in the percentage, depending on how precise the calculation must be.
I think you mean
so therefor since we can't take squaer root of negative
3t-9 must not be negative
basicaly, 3t-9 must be greater than or equal to 0
We will use vertex form of the parabola:
Where (h,k) is the vertex of our parabola. We know that focus and directrix are located at the same distance from the vertex. That distance is a.
We can use this to build a system of equations to calculate a and k. We already know that h=-5, keep in mind that focus and vertex share the same x coordinate.
We just add these two equations together:
We plug this back into the first equation:
That's all the information we need to write down the equation:
