Which is the focus of a parabola with equation y2 = 4x?
statuscvo [17]

Answer:

(1, 0)

Step-by-step explanation:

Please write this as y^2 = 4x; the " ^ " indicates exponentiation.

The appropriate equation for a horizontal parabola that opens to the right is

y^2 = 4px

Here, we are told that  y^2 = 4x; this tells us that 4p = 4, and so p = 1.  

Again, this parabola is a horizontal one and it opens to the right.  p = 1 is the distance of the focus from the vertex, and in this case p = 1.  Thus, the focus is at (1, 0) (situated on the x-axis).

there is 30 kilograms of 10% apple juice , how many kilograms of juice does it need to get 25% of apple juice?
Ghella [55]

Answer: 75. Hi! I learned something like this. Here is the explanation.

<h3>Step-by-step explanation: </h3><h3>So, I am not sure, but this is what I think. You would write it like this 30 kilograms equals 100%. Then, you would put the 100 percent over the 25 percent. So, it would look like this: 10% / 25% Then, you would multiply 30 times 25, because you can just multiply by 25 and not have to worry about the percent. 30 times 25 would give you 750 and then you would divide 750 divided by 10 and you would get 75.</h3><h3></h3><h3>Therefore, I think the answer is 75 kilograms of juice. </h3><h3>I hope this helps! </h3><h3></h3><h3>Sorry if this is wrong. </h3>
