Answer:

After 7 days the crystals will be 57.57 grams.

Step-by-step explanation:

In this the continuous exponential growth formula will be used.

y = A e ^rt

Where A = original amount = 10 grams

y is the growth after 7 days

e is Euler's number= 2.719

t is the time in hours , weeks, years etc.= 7 days

r  is the rate in decimals = 25% = 0.25

Putting the values in the formula:

y = A e ^rt

y = 10 e ^0.25 (7)

Calculating with the calculator

y = 10* 2.719^1.75

y= 57.57 grams.

After 7 days the crystals will be 57.57 grams.

Answer:

57.55g

Step-by-step explanation:

Use the formula f(t) = aert, where a = 10, r = 0.25, and t = 7. This gives f(7) = 10e(0.25)(7) = 10e1.75 ≈ 10(5.755) ≈ 57.55.

Coin Toss A coin is tossed upward with an initial velocity of 32 feet per second from a height of 16 feet above the ground.
AleksAgata [21]

Answer:

The object ever reach a height of 32  feet in 1 second

Step-by-step explanation:

The equation giving the object’s height : h = 16 + 32t -16t^2

Where h = object’s height

t = time

We are supposed to find Does the object ever reach a height of 32  feet

Substitute h = 32 in equation

32 = 16 + 32t -16t^2

32-16= 32t -16t^2

16= 32t -16t^2

1=2t-t^2

t^2-2t+1=0

t^2-t-t+1=0

t(t-1)-(t-1)=0

(t-1)(t-1)=0

t=1,1

So, The object ever reach a height of 32  feet in 1 second

The number of books donated to a library is increasing by 25% each month. Initially, there were 80 books donated to the library.
mamaluj [8]

Answer: 745

Step-by-step explanation: if there were initialy 80 books and its increasing by 25% every month, for month 1 we have:

25% = 0,25

increase is 1+0.25

M1 = 80.(1+0.25)¹ = 80.1.25 = 100

M10 = 80 (1+0.25)¹⁰ = 80. 9.313225 = 745.05 (end of the month)
