Answer:

x = 15

Step-by-step explanation:

The volume (V) of a pyramid is calculated as

V = \frac{1}{3} Ah ( A is the area of the base and h the height )

Here V = 225, A = x² and h = \frac{1}{5} x , thus

\frac{1}{3} × x² × \frac{1}{5} x = 225, that is

\frac{1}{15} x³ = 225 ( multiply both sides by 15 )

x³ = 3375 ( take the cube root of both sides )

x = \sqrt[3]{3375} = 15

Volume of square pyramid=lwh/3=225 in³.

l=w=Xin.

h=x/5in.

x³/15=225

x=15in.

A parabola opens up and passes through (-4, 2) and (6, -3). How do you know that (-4, 2) is not the vertex
Ainat [17]

Answer:

Step-by-step explanation:

The minimum is at the vertex of this parabola because it opens up.

Now if (-4, 2) is the minimum then  all the y values on the parabola must be > 2,

But we are given that  y = -3 is on the graph ( the point (6,-3) - that is y < 2 here,

Therefore (-4, 2)  cannot be the vertex .

What is the expression is factored form? X^2 + 14x + 48
galben [10]

Answer:

Factored form of the expression is ( x+ 8)(x + 6).

Step-by-step explanation:

The given expression is x² + 14x + 48.

We have to convert the expression in factored form

x² + 14x + 48 = x² + 8x +6x + 48

= x(x + 8) + 6(x + 8) = (x + 8)(x + 6)

Therefore the factored form of the expression is (x + 8)(x + 6).
