Mult. these 3 dimensions together to obtain the volume of the prism:
(12 ft)(5/12 ft)(10 1/12 ft). Expressing all of these factors as improper fractions, we get:
12 5 121 5(121) ft^3
------ * ------ * -------- = ----------------- = 50.42 ft^3 = volume of the prism
1 12 12 12
Suppose <span>A</span><span> is invertible. Therefore the equation </span><span><span>Ax=0</span></span><span> has only one solution, the zero solution. This means that the columns of </span><span>A</span><span> are linearly independent.</span>
Well, I don't know.
Let's figure it out together.
The best way to do that is to compare their unit rates:
The first woman's unit rate is (60 ft / 10 sec)
= (60 / 10) (ft/sec) = 6 ft/sec .
The second woman's unit rate is (25 ft / 5 sec)
= (25 / 5) (ft/sec) = 5 ft/sec .
Now we can see that the first woman walks 1 ft/sec faster
than the second one does.
