A plane is any 2 dimensional figure, so the least amount of points you can use to make a 2 dimensional figure is 3, which corresponds to a triangle

The results of a test of a metal are shown in the table, with strain in meters per meter, andstress in units called megapascals,

shusha [124]

The metal obey this law for values of strain until 0.05, where we have a linear relationship (each increase of 0.01 in the strain causes an increase of 100 in the stress). After this point, we don't have a linear relationship anymore.

c. Since an increase of 0.01 in the strain causes an increase of 100 in the stress, the slope is:

$m=\frac{100}{0.01}=10000$

Now, calculating the coefficient b (y-intercept), we have:

$\begin{gathered} (0.01,100)\colon \\ 100=0.01\cdot10000+b \\ 100=100+b \\ b=0 \end{gathered}$

So the equation is:

$y=10000x$

The maximum value of stress is 560, and occurs at strain = 0.07.

Mary can read 22 pages in 30 minutes how long would it take her to read a 100 page book? Right your answer in hours and minutes

mario62 [17]

30 divided by 22= 1.36
1.36 minutes for each page, to check 1.36x22= 29.92
1.36x100= 136 minutes.
Mary would need about 2 hours and 16 minutes to read a 100 page book.
