Answer:

Step-by-step explanation:

Both of the y= make upward parabolas

It is also going into the positive direction so it is $x = \frac{1}{4}y^2$

Answer:

1/4 y^2 =x

Step-by-step explanation:

The equation for a horizontal parabola is

(y - k)^2 = 4p(x - h)

The vertex is (0,0).

Substituting that in

(y - 0)^2 = 4p(x -0)

(y )^2 = 4p(x)

Since this opens to the right, p is positive

y^2 = 4px

Divide each side by 4

1/4 y^2 = px

Letting p =1

1/4 y^2 =x

Write the equation for the graphed function. I worked out y = 5 - 4 (x + 4)^2 but that isn't right. Any help would be appreciate

Vertex form for a parabola with vertex (p,q) is

$y = a(x-p)^2 + q$

We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>

$2 = a(-3 - -4)^2 + 5$

$2 = a + 5$

$a = -3$

Putting it together,

Answer: $y = -3(x + 4)^2 + 5$

We could multiply that out if we like but I won't bother.

the probability of rolling a 6 on a biased dice is 1/5 1) complete the tree diagram. 2) Work out the probability of rolling two

pickupchik [31]

Answer:

Step-by-step explanation:

Not 6 on all rolls in the diagram = 4/5

6 on all rolls in the diagram is 1/5

To find the probablity of rolling two sixes, 1/5 x 1/5 = 4/100 = 0.04 = 4%
