Mice21 [21]

ANSWER

(1,4)

(- \infty ,-3)

EXPLANATION

The x-values for which the graph is below the x-values below the x-axis is the interval on which the graph is negative.

We can see from the graph that, for

x <  - 3

the function is negative.

This can be rewritten as:

(- \infty ,-3)

Also for

1 < x < 4

the function is again negative.

This is also written as:

An open pit mine is being dug in the Buffalo Ridge mountain range. It will be 550 feet across and 290 feet deep. Based on sampli
Mnenie [13.5K]

The formula for volume of a cone is:

V = PI x r^2 x h/3

r = radius = 550 / 2 = 275

h = 290

Find the volume:

A) Volume = 3.14 x 275^2 x 290/3 = 22,954,708 cubic feet.

Now convert to tons and then multiply by ounces per ton of gold.

B) 22,954,708 /  10 = 22,95,470.8 tons

22,95,470.8 x 0.115 = 263,979 ounces of gold.
