This is very simple, you can use tally marks to find the amount of birthdays. Then divide it by 100. Good luck !
Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15. Filling in accordingly, we have

. Simplifying a bit gives us

and

. Raising that number inside the parenthesis to the 15th power gives us

. Multiplying to finish means that A(t) = $317.22
Answer:
Function
is shifted 1 unit left and 1 unit up.

Transformed function 
Step-by-step explanation:
Given:
Red graph (Parent function):

Blue graph (Transformed function)
From the graph we can see that the red graph is shifted 1 units left and 1 units up.
Translation Rules:

If
the function shifts
units to the left.
If
the function shifts
units to the right.

If
the function shifts
units to the up.
If
the function shifts
units to the down.
Applying the rules to 
The transformation statement is thus given by:

As function
is shifted 1 unit left and 1 unit up.
Transformed function is given by:

Answer:
Option D (r(t) = 3.50t +25
; r(8) = 53)
Step-by-step explanation:
The fixed cost to rent the kayak $25. This is the cost which remains fixed irrespective of the usage of the kayak. The variable cost of using the kayak is the cost which depends on the usage of the kayak. It is mentioned that the kayak is used for 4 hours and the company charges $3.5 for every half hour. The cost function is given by:
r(t) = 25 + 3.5t ; there r is the total cost of using the kayak and t is the number of half-hours the kayak is used.
4 hours means that there are 8 half-hours. Therefore, t=8. Put t=8 in r(t).
r(8) = 25 + 3.5*(8) = 25 + 28 = 53.
Therefore, Option D is the correct answer!!!
Answer:
The answer is: -0.5198
Step-by-step explanation:
CUBERT(8) – CUBERT(16) is the cube root of 8 - cube root of 16:
CubeRT(8) - CubeRT(16) =
2 - 2.5198 = -0.5198
Hope this helps! Have an Awesome day!! :-)
