Answer:
for question no. 8 there is a formula in coordinate geometry which i don't remembered .
but can help in solving question no. 9
<u>solution</u><u> </u><u>for</u><u> </u><u>9</u>
it is given that values varies directly that means
<u> </u><u>X1</u> = <u>X2</u><u> </u>
Y1 Y2 we have to find Y2
i.e. 9/5.4= -10/Y2
or Y2 × 9 = 5.4 × -10
Y2 = -54/9
Y2 = -5

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.
