Apopulation of dolphins has 400 individuals. after 20 years, this population has had 250 births and 170 deaths, so the population has grown to 480 individuals. what is the approximate yearly growth rate, r, of this population?

According to the question

N=Starting population 400

I=annual population increase 4

R= annual growth rate =?

Applying a formula:-

I=Rn

So,4=r×400  

    r= 4/400

       =0.01

i do not know this sorry : (

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
