Answer:

g o f = -[f(x)]² + 3 = -(|x|)² + 3 = -x² + 3 = g(x)

Step-by-step explanation:

g o f = g [ f(x) ]

This means replace the x of g(x) with f(x):

g o f = -[f(x)]² + 3 = -(|x|)² + 3

As x² ≥ 0 for any value of x (whether it be positive or negative), then -(|x|)² + 3 = -x² + 3 = g(x)

So g o f = g(x)

A recipe calls for an oven to be preheated to 400 °F. What is the approximate temperature of the preheated oven in Celsius degre

Nutka1998 [239]

Answer:

204 4/9 °C

Step-by-step explanation:

Put the number in the formula and do the arithmetic.

°C = (5/9)(400 -32) = 5/9(368) = 204 4/9

The temperature in °C is 204 4/9.

_____

Most likely, it would be written as 205 °C in a metric version of the recipe.

Answer:

s = $\frac{3}{10}$ m

Step-by-step explanation:

Given s varies directly with m then the equation relating them is

s = km ← k is the constant of variation

To find k use the condition s = 9 when m = 30 , thus

9 = 30k ( divide both sides by 30 )

k = $\frac{9}{30}$ = $\frac{3}{10}$

s = $\frac{3}{10}$ m ← equation of variation

Answer:

Rewriting p(x) as a product of linear factors: $\mathbf{f(x)=(x+3)(x-2)(x+6)}$

Step-by-step explanation:

The polynomial $p(x) = x^3 + 7x^2 - 36$ has a known factor of $(x + 3)$

We need to find other factors.

First we find quotient of $p(x) = x^3 + 7x^2 - 36$ divided by $(x + 3)$

The division is shown in image attached.

The quotient is: $x^2+4x-12$

Now, factoring the quotient $x^2+4x-12$

$x^2+4x-12\\=x^2+6x-2x-12\\=x(x+6)-2(x+6)\\=(x-2)(x+6)$

The other two factors are (x-2)(x+6)

So, Rewriting p(x) as a product of linear factors: $f(x)=(x+3)(x-2)(x+6)$
