Explanation:</h2>
We can write the Slope-Intercept form of the equation of a line as:
The slope is a measure of the steepness of a line It is a ratio between vertical change (run) and horizontal change (rise), so we can also write the slope (m) as:
We have the following facts:
- If we increase the rise, the slope also increases and if we decrease the rise the slope also decreases.
- If we increase the run, the slope decreases and if we decrease the rise the slope increases.

The space between the two spheres will be the volume of the larger sphere minus the volume of the smaller sphere. Given that the volume of any sphere is:
V=(4πr^3)/3 The space between to sphere of different radius and positioned about the same center is:
S=(4πR^3)/3-(4πr^3)/3 I used S=volume of space, R=larger radius and r=smaller radius...
S=(4π/3)(R^3-r^3), we are told that R=5 and r=4 so
S=(4π/3)(5^3-4^3)
S=(4π/3)(125-64)
S=(4π/3)(61)
S=244π/61
S=4π cm^3
S≈12.57 cm^3 (to nearest hundredth of a ml)
the first 4 is in the hundreds thousands place. The second 4 is in the ten thousands place
Consider the number 1457.506
We have to round it to the nearest hundredth.
Consider the digit at hundredth place which is '0'. Now, consider the digit next to the hundredth place. Since, the digit next to the hundredth place is '6' and it greater than 5. Therefore, we will add '1' to the hundredth place.
So, the number rounded to the nearest hundredth is 1457.51
