An endangered species has only 450 animals remaining in the wild. The population decreases by 10% each year. Write an equation to describe the number of animals left after x years.​

A = 450(1.1)^x

Step-by-step explanation:

Since the animal decreases by 10% each year, we will use the compound interest formula to find the required equation

A = P(1+r)^t

P is the number of animals = 450

r is the rate = 10% = 0.1

t is the time = x

Substitute into the formula;

A = 450(1+0.1)^x

A = 450(1.1)^x

This gives the required expression

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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)
