True statements are:

It has a directrix of x = - 4.
It has a focus at (4, 0).

Step-by-step explanation:

We have the following statements to check on whether it's right or wrong:

1. It has a directrix of x = -4:

According to figure , parabola directrix is at -4 i.e. at x = -4 , Therefore this statement is true!

2. It opens to the left:

In figure, Parabola opens to right not left , Therefore this statement is wrong!

3. It has a vertex at the origin:

Vertex of Parabola is at what points not shown in figure. Therefore this statement cannot be confirmed as true.

4. The axis of symmetry is the y-axis:

Axis of symmetry for above parabola is x-axis as it cuts parabola into two equal halves , y-axis doesn't do this ! Therefore this statement is wrong!

5. It has a focus at (4, 0):

Parabola focus is at $F(4,0)$ on x-axis . And so, Therefore this statement is true!

A clear box has the shape of a rectangular prism and is filled with sand. Find the volume if the box

Strike441 [17]

Answer:

24 m³

Step-by-step explanation:

Since you didn't state the dimensions of the rectangular prism, and you didn't add a picture to show it's dimensions, then permit me to assume dimensions for the question

Assuming it's breadth is 2 m.

Assuming it's length is 4 m.

Assuming it's height is 3 m

Then the volume of a rectangular prism is given as l * b * h. Which means we multiply all the sides by one another. From my assumption of values, we have that 2 * 3 * 4, and this gives us 24 m³

24 m

Now what you'd do is substitute your values for my assumed values.. Cheers

Explain your process of converting a mixed number to an improper fraction.explain your process of converting a improper fraction

scoundrel [369]

To make a improper fraction (eg11/4) a mixed number (eg 2 3/4) you must see how many times the numerator (number on the top) fits into the denominator (number on the bottom). This will give you the Whole number (big number) whatever is left will be the new numerator on the fraction (keeping the denominator the same).

To make a mixed number a improper fraction multiply the whole number by the denominator. Then add this number to the numerator.
