.A mouse population is 25,000 and is decreasing at 20% per year. What is the population after 3 years? Exponential growth or decay?: Write a function that represents the situation: - Initial amount: -Growth/Decay rate: -

its decreasing

Step-by-step explanation:

3 x 25000 is 75000 and 20 percent of that is 15000. hopefully you can construct a function from this.

answer is c

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
