Answer:
Step-by-step explanation:
<u>Consider the parent function:</u>
The graph of the function open up and the vertex is at the origin, the point (0, 0)
Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:
The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:
<u>Since all the options have 1/20 as a coefficient, our function is:</u>
This is option B
Answer:
thirty
Step-by-step explanation:
Answer: A
<u>Step-by-step explanation:</u>
≅
⇒ ∠XOY ≅ ∠ZOY
≅ since they are both a radius
≅ based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So, ≅ by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
