Answer:
The correct option is the last one.
Step-by-step explanation:
To transform the graph of
into
the following steps are fulfilled:
1) Move the graph 2 units to the right:
Let
then
Notice that the cut point has been moved to x = 2.
2) Reflect on the x axis:
To reflect a graph on the x-axis we do
Then 
3) Stretch according to factor 2.
For this we do 
Then we have
4) Move up the graph in two units:
We do 
Then 
These steps coincide with those listed in the last option. Therefore the correct option is the last one.
"Translate 2 units on the right, reflect on the x-axis, stretch according to the factor 2 and translate 2 units"
Answer:
112
Step-by-step explanation:
The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w
We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)
126 = (0.18)w, divide both sides by 0.18
126/(0.18) = w = 700
9th graders are 16% of the school or 16% of 700 students
c = (0.16) 700 = 112 students
It is an acute triangle bc 8 squared + 14 squared is 260 and that is more than 15 squared (225)
