Manny observed a Northern Gannet, a deep diving seabird, hovering at a height of 10 meters above the ocean
surface. The bird then dove into the water, diving to a depth of 16 meters before coming to the surface. The dive can
be modeled by a quadratic function,
y = x2 - 10.3x + 10, where x represents the time the dive lasted in seconds and y represents the height of the bird in
meters. Use the graphing calculator to graph the equation. After how many seconds did the bird surface? Round your
answer to the nearest tenth.

Intro

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

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! : )

my guess is

step-by-step explanation:

combine all like terms then its just a 2 step equation
