Answer:

H (b) = 0.722^b(6)

Step-by-step explanation:

The first time the basketball bounces it reaches a height of (1-0.278)(6) = (0.722) (6).

The second time the basketball bounces it reaches a height of (0.722) (0.722) (6) = [(0.722) ^ 2] (6). Therefore, after b rebounds the height that the basketball will reach is given by:

H (b) = 0.722^b(6)

At the start of 2014, Mike's car is worth 12000. the car depreciates by 30 percent every year. how much is his car worth in 2017
Anarel [89]

Answer:

$4,116

Step-by-step explanation:

Worth of Mike's car at the start of 2014 = $12,000

If the car is said to depreciates every year by 30% = 30/100 = 0.3

The worth of the car at the start of 2017 is what we are to determine.

This means that the car depreciated by 30% (0.3) for 3 years since 2014 (2017 - 2014 = 3 yrs)

The worth at the start of 2017 would be calculated as follows:

12,000 × (1 - 0.3)³

= 12,000 × (0.7)³

= 12,000 × 0.343

= 4,116

Worth of the car at the start of 2017 would be $4,116

The area of a trapezoid is 864 cm2. It has a height of 24 cm, and the length
Paha777 [63]

Answer:

Step-by-step explanation:

Area of trapezium = 1/2 × h (a+b) = 864 cm^2

where h is the height and a and b are the two parallel sides

h = 24 cm

a = 30 cm

b = ?

1/2 × 24 ( 30 + b ) = 864

12 ( 30 + b ) = 864

30 + b = 864/12

30 + b = 72

b = 72 - 30

b = 42

Therefore the lenght of other base = 42 cm
