Consider the following data set which relates the hemoglobin levels h (kg/dL) of workers and the altitude a (km) above the sea l

Nikolay [14]

Answer:

The highest permanently tolerable altitude is 52.53 km.

Step-by-step explanation:

We have to calculate the maximum altitude that the residents/workers can tolerate.

This altitude is at which the hemoglobin conventration is 0.001 of the concentration at sea level.

We can express that as:

$\frac{h_{max}}{h_0}=\frac{c_1e^{-c_2a_{max}}}{c_1e^0} =e^{-c_2a_{max}}=0.001\\\\-c_2*a_{max}=ln(0.001)\\\\a_{max}=-ln(0.001)/c_2=6.9078/0.1315\\\\a_{max}=52.5308$

The highest permanently tolerable altitude is 52.53 km.

Solve for c.<br> a=11+4b−4c

mamaluj [8]

Ok so first we subtract 11 on each side so we get a-11=4b-4c then we do-4b on each side to gets a-11-4b=-4c finally divide -4 to each side to get a-11-4b/-4=c

What the value of q?

Reil [10]

Step-by-step explanation:

this is very simple.

you can compare this to the question "in my bag are 70 pieces of fruit. 30 of them are apples. how many pieces of other fruit are there ?"

well, it is 70 - 30 = 40 !

that's it ! that is all there is to it.

so, q = 40°

what is still unclear, please ?
