The height of a pyramid-shaped sculpture with a square base is one half the length of each side. The volume of the sculpture is

Nimfa-mama [501]

The volume of a pyramid is V = 1/3 x base length^2 x height

Let X = base length.

We are told the height is 1/2 the length, so height would be 1/2x

Now we have:

972 = 1/3 * x^2 * 1/2x

Simplifying we get:

972 = 1/6x^3

Multiply both sides by 6:

5832 = x^3

Take the cube root of both sides:

x = 18

The length of the base is 18 inches.

The height is 1/2 that, so the height would be 18/2 = 9 inches.

What is the sign of 3 x y 3xy3, x, y when x > 0 x>0x, is greater than, 0 and y < 0 y<0

Colt1911 [192]

Answer:

The sign is negative

Step-by-step explanation:

Given

$Expression = 3xy$

$x > 0$

$y$

Required

Determine the sign

The expression can be split into 3 factors

$(3) (x) (y)$

If x > 0 then x is positive and If y < 0 then y is negative

So, the expression becomes:

$(+3) (+x) (-y)$

Leave only signs

$(+) (+) (-)$

$+ * + = -$

So, we have:

$(+*+) (-)$

$(+) (-)$

$+ * - = -$

So, we have:

$(+) (-) = -$

Hence, the sign of the expression is negative

Take for instance;

$x = 2$

$y = -4$

The expression would be:

$3 *2 * - 4 =-24$ -- negative
