For a particular year, the total school-aged population (5-17 years of age) in the US (in millions is given approximately by y= -0.03t^2 + 1.5t + 32 where t is time in years and t=0 corresponds to 1950. Find the instantaneous rate of change (in millions/year) of this population in 2000.

In certain parts of the world, the number of deaths N per week have been observed to be linearly related to the average concentration x of sulfur dioxide in the air. Suppose there are 97 deaths when x=100 mg/m^3 and 110 death when x=500 mg/m^3

a) What is the functional relationship between N and X?

b) Use the function in part (a) to find the number of deaths per week when x=300 mg/m^3. What concentration of sulfur dioxide corresponds to 100 deaths per week?

The regular admission price to an evening performance at the Coast cinema is $7, while the price for children under 12 years old is $4 and the price for seniors at least 60 years of age is $5

(a) Find a mathematical model expressing the admission price as a function of the person's age.

(and can someone help me how to graph this with piecewise?)

Okay, so im in the Fall of the first year in this game, and i was wondering, is there an animal team for the sprites that will take care of your animals? (like brush, milk them, etc) Like in the Harvest moon: Ds cute version. I was wondering since its getting tiring to take care of each one and to mention im building another barn.

Thanks in advance :)

Give two observable sex-linked traits in humans. Show possible parental cross

Trait A=

Trait B=

2. Is it possible for a child with blood type O to be produced by two AB parents? Explain.

3. When a child is type O, the mother type A, can a man of the following blood types be the father of a child?

A=

B=

AB=

O=

please help and thanks!

What is the diploid genotype if the gamete genotype is....?

Can someone please link me to a video about providing chemical reactions?

Eg. ZnSO4 + HNO3 -> _____

and another example. ___NH3 + h2SO4 -> _____?

*Its not about finding the coefficients for balancing chemicals, but the formula itself.

I wish ya'll could help, thanks

why does NITRIC ACID have no effect in dissolving a black precipitate(formed from heating aqueous solution copper(II) hydroxide) and no dissolving occurs when put in zinc metal?? Whie SULFURIC ACID has?

Kindly state as many as poosible, thank you

When i right click 'paragraph' it only shows left and right margins..
