A cone is cut by a plane parallel to the slant height of the cone. What is the shape of the cross section that is formed?

zimovet [89]

A cross section is a shape formed by cutting an object using a plane. For this case, a cone is sliced parallel to the slant height so the cross section formed would be a plane with a U-like shape. From the image attached, the correct answer is the second option.

Find all the solutions to the equation 7sin^2x -14sinx+2=-5

Allisa [31]

I will get you started.

Let sin x = u

Then 7sin^2x -14sinx+2=-5 become

7u^2 - 14u = - 5

7u^2 - 14u + 5 = 0

Steps:

1. Solve for u.

2. Back- substitute for u.

3. Take the arcsin on both sides to find the angle(s).

You finish.

The perimeter of a square is equal to four times the length of a side. Write the direct v variation equation that represents the

sveticcg [70]

Answer: $y=4x$

Step-by-step explanation:

A direct variation equation has the form:

$y=kx$

Where k is a constant.

By definition, we know that the perimeter of the square is the sum of the lengths of its sides or, as all the sides are equal, you can multiply the lenght of any side by 4.

Then, knowing that y is the dependent value and x the independent value and the constant k=4, you can write the following direct variation equation that represents the situation.

$y=4x$
