NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by h ( t ) = − 4.

Aleks [24]

Answer:

A.) 24.08 seconds

B.) 825.42 metres

Step-by-step explanation:

function of time is given as

h ( t ) = − 4.9 t 2 + 118 t + 115 .

Where a = -4.9, b = 118, c = 115

Let's assume that the trajectory of the rocket is a perfect parabola.

The time t the rocket will reach its maximum height will be at the symmetry of the parabola.

t = -b/2a

Substitute b and a into the formula

t = -118/-2(4.9)

t = 118/9.8

t = 12.041 seconds

Since NASA launches the rocket at t = 0 seconds, the time it will splash down into the ocean will be 2t.

2t = 2 × 12.041 = 24.08 seconds

Therefore, the rocket splashes down after 24.08 seconds.

B.) At maximum height, time t = 12.041s

Substitute t for 12.041 in the function

h ( t ) = − 4.9 t 2 + 118 t + 115

h(t) = -4.9(12.041)^2 + 118(12.041) + 115

h(t) = -4.9(144.98) + 118(12.041) + 115

h(t) = -710.402 + 1420.82 + 115

h(t) = 825.42 metres

Therefore, the rocket get to the peak at 825.42 metres

Which graph represents the function h(x) = -(x+6)³-3?

jek_recluse [69]

The correct answer is option B which is the second graph in the image showing the function h(x) = -(x+6)³-3.

<h3>What is a graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

Given function:

h(x) = -(x+6)³-3.

The given function is cubic and cuts the x-axis at the point (-7.442,0) the graph is bending towards the left side in the second quadrant.

Therefore the correct answer is option B which is the second graph in the image showing the function h(x) = -(x+6)³-3.

Feather color in budgies is determined by two different genes, Y and B, one for pigment onthe outside and one for the inside of

Svet_ta [14]

Answer:

Therefore, the following results are not possible:

A) green offspring only

B) yellow offspring only

D) green and yellow offspring.

Step-by-step explanation:

We know that feather color in budgies is determined by two different genes. For blue color are combinations yyBB or yyBb. For white color is combination yybb.

By combining these two colors we can not get green and yellow.

Because green and yellow colors are in this form:

Green: YYBB, YyBB, or YYBb

Yellow: YYbb or Yybb.

Therefore, the following results are not possible:

A) green offspring only

B) yellow offspring only

D) green and yellow offspring.
