Rom4ik [11]

Answer:

FV= $8,436

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $5,700

Simple interest (i)= 8% = 0.08

Number of periods (n)= 6 years

<u>To calculate the future value (FV), we need to use the following formula:</u>

FV= PV*i*n + PV

FV= 5,700*0.08*6 + 5,700

FV= $8,436

Write a recursive rule for the sequence 4,10,16,22
Phantasy [73]

Answer:

a_{n+1} = a_{n} + 6

Step-by-step explanation:

The terms have a common difference d between consecutive terms, that is

10 - 4 = 16 - 10 = 22 - 16 = 6

To obtain the next term add 6 to the previous term ( recursive rule ), thus

a_{n+1} = a_{n} + 6 with a₁ = 4

ElenaW [278]

Answer:

a) The maximum height that the ball reaches is 73.1 meter

b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds

Step-by-step explanation:

The complete question is

During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?

Solution:

For maximum height

\frac{dh}{dt} =0

\frac{d(5t^2 + 22t + 0.5)}{dt}\\ 10t + 22 = 0\\t = 2.2seconds

a) Maximum height

5 * t^2 + 22t + 0.5

= 5 * 2.2 *2.2 + 22 * 2.2 + 0.5 \\= 73.1

b) Time elapsed when the ball reaches maximum height is 2.2 seconds
