In January of 1992, which is usually the middle of the winter dry season, a weather pattern attributed to "El Nino" created a two week period of cold, wet conditions in the roosting areas, followed by freezes and even snowfall, Lincoln Brower and Bill Calvert estimated mortality to be 70% at several roosts. According to Bill Calvert, mortality at the roost sites is normally 15-20%, so a 70% loss was very alarming. This loss, coupled with usual threats to the integrity of the roosting sites, such as deforestation, once again drew considerable media attention to the problems of Monarch conservation. 4. If there were 20,000 monarch butterflies in this roosting area how many would have been lost (70%)?

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
