Step-by-step explanation:
You have a vertex coordinate and 2 points. In order to write the equation for that parabola, you only need the vertex and one point. We will fill in the following work form of the parabola:
, where h and k are from the vertex and x and y are from the point. Filling in:
and
and
and
9 = 9a s0
a = 1.
Now we can write the equation, filling in a, the only unknown we had, which we now know is 1:
Answer:
a rational number
Step-by-step explanation:
3.4 is a terminating decimal. That means that after the 4 in 3.4 there are no other numbers (the number "ends" after the 4) Also, 3.4 can be written as a RATIO of two numbers (looks like a fraction)
3.4 = 3 4/10 = 3 2/5
= 15/5 + 2/5
= 17/5
If you put 17÷5 in a calculator it would say 3.4
3.4 = 17/5
3.4 is a rational number.
