As you want a 60% discount, you must find 40% of $12.25.

40% of $12.25 is the same as 2/5 of $12.25.

Now, 12.25 / 5 = 2.45

And, 2.45 x 2 = 4.90

--------------

This means that 60% off $12.25 is $4.90.

A spherical ball of wax with a radius of 8 inches is melted and poured into a container shaped like a rectangular prism with a 1
avanturin [10]

It is expected the height of the melted wax in this shape is 9.57 inches, this height would make the volume remain constant.

<h3>What is the volume of the spherical ball?</h3>

The volume of a sphere can be calculated using the formula V = 4/3 πr³. Let's use this formula to calculate the volume of the spherical ball of wax:

  • V = 4/3 π8³
  • V = 4/3 π 512
  • V= 4/3 x 3.1416 x 512
  • V =2144.66 cubic inches

<h3>What is the height of the new shape?</h3>

Considering the volume should be the same  (2144.66 cubic inches) and the volume of this shape can be calculated by multiplying the sides, this would be the equation:

  • 2144.66 = 14 x 16 x y ( unknown value)
  • y= 2144.66 / 14 x 16
  • y = 9.57

This means the height would be 9.57 inches.

50 POINTS!!!!! HELPFor the exponential function f(x)=a^x,a&gt;0,a≠1 what is the domain? what is the range?
White raven [17]
I have included a graph to help you see what the domain and range would be
There are no minus y values. 
0<y< infinity y is included in the reals.
The domain is 
- infinity < x < infinity.

I don't want to say that either x or y can equal - or + infinity. Some teachers allow it. You have to ask your instructor what they will accept.

The blue line is y = 4^x
The red line is y = 2^x
