Mathematics

Flura [38]3 years ago
4 0

Answer:

See below and attached picture

Step-by-step explanation:

a. To graph the equation set y = 0 and solve for t.

y = -16t² + 100

0 = -16t² + 100

100 = -16t²

6.25 = t²

+/- 2.5 = t

Mark the points (-2.5,0) and (2.5,0). Then mark the highest point at (0,100). Draw a curve or parabola to connect the points.

b. Domain is the set of t values. This is the time it's in the air. The graph shows it at height 100 at t = 0 and at height 0 at t = 2.5. The domain is [0, 2.5].

Range is the set of y values. This is the height of the object. The graph shows it at height 100 at the beginning and then falls to height 0. The range is [0,100].

c. The graph has the point (1,84). This means it was at height 84 feet at 1 second.

d. The graph has a point about (1.75, 50). This means at about 50 feet it was 1.75 seconds.

e. The shingle is at height 0 feet at 2.5 seconds when it crosses the x-axis.

Answer:

8w : 3.8974342 ≈ 3.9 or 4 (hope it help)

Step-by-step explanation:

1w : 2

2w : 2 + 10% = 2.2

3w : 2.2 + 10% = 2.42

4w : 2.42 + 10% = 2.662

5w : 2.662 + 10% = 2.9282

6w : 2.9282 + 10% = 3.22102

7w : 3.22102 + 10% = 3.543122

8w : 3.543122 + 10% = 3.8974342

3.8974342 ≈ 3.9 or 4
