Answer: f(x)=(x-5)(x+5)(x+2)
Points given: (5,0),(-5,0),(-2,0)
To get the factors do x- the roots above:
Solve for x:
X+5=0 X=-5
X-5=0 X=5
X-2=0 X=2
Now we have (x-5),(x+5),(x+2)
Another point that seems to be given is (3,-80)
F(3)=-80= a(3-5)(3+5)(3+2)
-80=a(-2)(8)(5)
-80=a(-80) (Solve for a)
-80/-80=a(-80)/-80
1=a
F(x)=1(x-5)(x+5)(x+2)
Okay to the first number in the ordered pair is the x and the second is the y. So (x,y) when you put a dot on the coordinate plane such as (2,3), you have to go the the horizontal line which is x and go over right 2 spaces(depending on how many numbers is one space) then go up 3. Do that same thing for each of the order pairs. Eventually you will have 4 dots. Connect those dots then you will have the quadrilateral. I hope this helps you!
Answer:
A- Using real world problems to help students learn to solve them on their own
Explanation:
"Problem-based learning" is a teaching approach that centers on students. It allows the student to learn on their own or to solve problems on their own. This is also based on their own <em>"reasoning"</em> and <em>"reflection." </em> So, the role of the teacher here is to facilitate or guide the students. He doesn't need to provide direct instruction to the student. The goal here is "self-identified," so this means that the <u>students identity their own goals.</u> Real word problems are used in order for the students to learn how to solve them on their own.
So, this explains the answer.
Answer:
5 x S = M (S=Students, M = money); 5 x 25 = 100
