Smoking tobacco is bad for your circulatory health. in an attempt to maintain the blood's capacity to deliver oxygen, the body increases its red blood cell production, and this increases the viscosity of the blood. in addition, nicotine from tobacco causes arteries to constrict. for a nonsmoker, with blood viscosity of 2.5×10−3pa⋅s, normal blood flow requires a pressure difference of 8.0 mm of hg between the two ends of an artery. if this person were to smoke regularly, his blood viscosity would increase to 2.7×10−3pa⋅s, and the arterial diameter would constrict to 90 % of its normal value.
what pressure difference would be needed to maintain the same blood flow in mm of hg?

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

yup its correct its: c) b b

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
