The function H(t) = −16t2 + 60t + 95 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in the air along a path represented by g(t) = 20 + 38.7t, where g(t) is the height, in feet, of the object from the ground at time t seconds.Part A: Create a table using integers 1 through 4 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points)

Part B: Explain what the solution from Part A means in the context of the problem. (4 points)

Answers

h(t) = -16t² + 60t + 95
g(t) = 20 + 38.7t

h(1) = -16(1²) + 60(1) + 95 = -16 + 60 + 95 = -16 + 155 = 139
h(2) = -16(2²) + 60(2) + 95 = -16(4) + 120 + 95 = -64 + 215 = 151
h(3) = -16(3²) + 60(3) + 95 = -16(9) + 180 + 95 = -144 + 275 = 131
h(4) = -16(4²) + 60(4) + 95 = -16(16) + 240 + 95 = -256 + 335 = 79

g(1) = 20 + 38.7(1) = 20 + 38.7 = 58.7
g(2) = 20 + 38.7(2) = 20 + 77.4 = 97.4
g(3) = 20 + 38.7(3) = 20 + 116.1 = 136.1
g(4) = 20 + 38.7(4) = 20 + 154.8 = 174.8

Between 2 and 3 seconds.
The range of the 1st object is 151 to 131.
The range of the 2nd object is 97.4 to 136.1

h(t) = g(t) ⇒ 131 = 131

It means that the point where the 2 objects are equal is the point where the 1st object is falling down while the 2nd object is still going up.

What is the value of the variable?

19b = 38

Answers

The answer is 2. You divide 19 to sides of the equation, so you will get b=38/19, therefore your final answer is 2.

19b = 38

b = 2

Answers

The scale factor of the dilation is option (C) 3/2 is the correct answer.

What is transformation of dilation?

Dilation is a kind of transformation in which an object is resized based on a scale factor. Dilation is the process of enlarging or reducing the size of a geometrical object without changing its shape.

For the given situation,

The diagram shows the triangle TUV and the dilated triangle T'U'V'.

In the plane, V is at 4.8 units and V' is at 3.2 units.

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

$Scale factor =(Dimension of the new shape)/(Dimension of the original shape)$

⇒ $Scale factor =(4.8)/(3.2)$

⇒ $Scale factor =1.5$

From the options the value that has 1.5 as the value is $(3)/(2)$ .

Hence we can conclude that the scale factor of the dilation is option (C) 3/2 is the correct answer.

The dilation of one of the distances from the origin to one of the endpoints of each triangle was from 8 to 3.2, since we add the lengths. Therefore, the scale factor was 3.2/8 = 2/5
