A certain business is marketing its product and has determined that, when it raised the selling price of its
product, its sales went down. The number of units
sold, P, is modeled by the equation P=1200-20s,
where s is the selling price, in dollars. Based on this
model, what is the decrease in selling price from 700
units sold to 900 units sold?
a) 5
b) 10
c) 15
d) 20

i think that you should ask google for the answer to that problem because if we don't know it google does

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
