A culture started with 4,000 bacteria. After 8 hours, it grew to 4,800 bacteria. Predict how many bacteria will be present after

13 hours. Round your answer to the nearest whole number.
p= Ae^k(t)
Note: when solving for k, round to four decimal places.

Answer:5,378

Step-by-step explanation:

At 0 hours: t=0 and A= 4,000

At 8 hours:t=8 and p = 4,800

So basically you just do

P= 4,000 times 1.3445

Which equals p= 5,378

Hope this helps :)

The dimensions of a basketball court are shown below. Suppose a player throws the ball from a corner to a teammate standing at t
creativ13 [48]

The 94 ft. by 50 ft dimensions of the court obtained from a similar question posted online, gives;

a. The ordered pair representing the location of the player in the bottom right corner is (47, -25)

b. The distance traveled by the ball obtained using Pythagorean theorem, is approximately 53.2 feet.

<h3>How can Pythagorean theorem be used to find the distance the ball travels?</h3>

The possible dimensions of a rectangular court obtained from a similar question posted online are;

Length of the basketball court = 94ft.

Width of the basketball court = 50 ft.

From the question, we have;

Location of the court center = The origin of a coordinate plane

a. The ordered pair that represent the location of a player in the bottom right corner is found as follows;

Let (x, y) represent the coordinates of the bottom right corner of the court, we have;

Horizontal distance from the center of the court (the origin) to the right boundary of the court, <em>x </em>= (94 ft.)/2 = 47 ft.

Vertical distance from the center to bottom of the court, <em>y </em>= (50 ft.)/2 = 25 ft.

Following the convention of points to the right and above the origin being positive, while points below the origin are negative, we have;

The ordered pair (the coordinates of the player) that represents the location of the player in the bottom right corner is therefore;

  • (x, y) = (47, -25)

b. The distance, <em>d</em>, that the ball travels is given by Pythagorean theorem as follows;

d = √((47 - 0)² + ((-25) - 0)²) = √(2834) ≈ 53.2

  • The ball travels approximately 53.2 feet.
