The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. The distance between Boise, Idaho, and

Burka [1]

Answer: C) 688 km

=================================================

Work Shown:

k = 1.6d

k = 1.6*430

k = 688

430 miles is roughly equivalent to 688 km.

More accurately, 430 miles = 692.01792 km, so this approximation isn't too far off.

If ab =8 and a square + bsquare =35 then (a-b) cube

vaieri [72.5K]

$\text{Given that,}\\\\ab = 8 ~ \text{and}~ a^2 +b^2 = 35\\\\\text{Now,}\\\\(a-b)^2 = a^2 +b^2 -2ab\\\\\implies (a-b)^2 =35 - 2 (8) \\\\\implies (a-b)^2 = 19\\\\\implies a-b = \pm\sqrt{19}\\\\\text{Case 1:}\\\\(a-b)^3 = (a-b)^2(a-b)\\\\\implies (a-b)^3 = 19 \left(\sqrt{19}\right)\\\\\text{Case 2:}\\\\(a-b)^3 = (a-b)^2(a-b)\\\\\implies (a-b)^3 = -19 \left(\sqrt{19}\right)$

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.
