If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w circle r) (x)?
VashaNatasha [74]

Answer:

(-\infty, 0)

Step-by-step explanation:

(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]

We have that:

r(x) = 2 - x^{2}

w(x) = x - 2

Composite function:

w(r(x)) = w(2 - x^{2}} = 2 - x^{2} - 2 = -x^{2}

-x^{2} is a negative parabola with vertex at the original.

So the range(the values that y assumes), is:

(-\infty, 0)

The table shows the altitudes of four different cities. What is the correct way to arrange the altitudes in decreasing order?
ki77a [65]

Answer:

A. 58, 13,-35,-51

Step-by-step explanation:

Start with the greatest positive number, 58. Then use the next greatest positive number, 13. When it comes to negative numbers, the number with the smaller absolute value is greater.

|-35| = 35

|-53| = 53

-35 has a smaller absolute value than -53, so -35 is greater than -53.

Answer: A. 58, 13,-35,-51

Lesechka [4]

Answer:

C. h=3V/a^2 is the correct answer

Step-by-step explanation:

Given:

V=1/3a^2h

It can be rewritten as

V=1/3 *( a^2) * h

Divide both sides by (1/3)*h

V / (1/3*h) = (1/3)* (a^2) * h / (1/3)*h

V÷1/3*h = a^2

V÷3/1*h=a^2

3V/h=a^2

Multiply both sides by h

3V/h*h=h*a^2

3V=h*a^2

h=3V/a^2

C. h=3V/a^2 is the correct answer
