UkoKoshka [18]

Answer:

D- The blackcaps will begin nesting at their wintering sites in Spain or the United Kingdom, resulting in a larger blackcap population migrating back to Germany after the breeding season has ended.

Step-by-step explanation:

By the inhabitants of Spain and the United Kingdom placing feeders out for the blackcaps, the birds in their nesting sites during the winter will have food to eat, meaning a bigger population of the Blackcaps when they return to their main home in Germany.

This best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter.

2. Ariana has created a paper airplane for her physics class at school where all the students will be testing their planes by se
sergiy2304 [10]

Answer:

2. The airplane will crash into the ground after 5 seconds.

3. The domain of the function is [0,30] and range of the function is [-\infty,900].

Step-by-step explanation:

2.

Ariana initial attempt is modeled by the function,

h(x)=x^2-12x+35

where, h is the height in feet and x is the time in seconds of the paper airplanes path.

If airplane crash into the ground, then h(x)=0,

0=x^2-12x+35

0=x^2-7x-5x+35

0=x(x-7)-5(x-7)

0=(x-7)(x-5)

Equate each factor equal to 0.

x=5,7

Therefore the airplane will crash into the ground after 5 seconds.

3.

The height of the rocket in meters is modeled by the function shown below, where t is time in seconds.


h(t)=-4t^2+120t

The value of t must be positive because time can not be negative.

Find the zeros of the function.

0=-4t(t-30)

t=0,30

The leading coefficient is negative, so the it is a downward parabola. Since the zeros of the function are 0 and 30, therefore the function is negative before 0 and after 30.

The height can not be negative, so the domain of the function is

0\leq t\leq 30

The vertex of a downward parabola is the maximum point.

Vertex of a parabola,

(\frac{-b}{2a},h(\frac{-b}{2a}))

(\frac{-120}{2(-4)},h(\frac{-120}{2(-4)}))

(15,h(15))

Put t=15 it in the equation.

h(15)=-4(15)^2+120(15)=900

(15,900)

The range of the function is

[-\infty,900]

Therefore the domain of the function is [0,30] and range of the function is [-\infty,900].
