A parabola has vertex (2, 3) and contains the point (0, 0). find an equation that represents this parabola.

1 answer:

7 0

First write it in vertex form :-

y= a(x - 2)^2 + 3 where a is some constant.

We can find the value of a by substituting the point (0.0) into the equation:-

0 = a((-2)^2 + 3

4a = -3

a = -3/4

so our equation becomes y = (-3/4)(x - 2)^2 + 3

Determine if the given sides are a triangle or not <br><br> A. 21 cm, 7 cm, 6 cm

fgiga [73]

Answer:

This is not a triangle

Step-by-step explanation:

If you use the triangle inequality theorem you can reach your answer.

The theorem states that if you add the length of any 2 sides together, you will have a length greater than the length of the other side. Using this method we can easily see that 7+6=13 which is less than 21. Meaning this is not a triangle

PLEASE HELP

Since the domain are the x-values of the function, we need to find the y-values using those x-values.
- for x= $\frac{1}{2}$ , $log x_{2} ( \frac{1}{2} )=-1$ . Now we have our first ordered pair: $( \frac{1}{2} ,-1)$
- for $x=1$ , $log_{2} (1)=0$ which gives us our next ordered pair: $(1,0)$
- for x=2, $log_{2} (2)=1$ , so (2,1)
- for x=4, $log_{2} (4)=2$ , so (4,2)
- for x=8, $log_{2} (8)=3$ , so our last order pair is (8,3)

Finally we can plug the points and joint them to create our graph:
