Answer: x=3

I got to the answer by doing simple math. Both sides must be even.

5x-4

5(3)-4= 15-4 = 11

x+8

3+8= 11

So x=3

The table below shows the distance d(t) in feet that an object travels in t seconds: t (seconds) d(t) (feet) 1 15 2 60 3 135 4 2
storchak [24]

Answer:


Step-by-step explanation:

Answer:


Option B is correct


The average rate of change of d(t) between 2 second and 4 second is; 90 ft/s


and it represents the average speed of the object between 2 seconds and 4 seconds.


Step-by-step explanation:


Average rate of change of function is defined as the ratio of the difference in the function f(x) as it changes from a to b to the difference between a and b. Then, the average rate of change is denoted as A(x).




As per the given statement, the distance d(t) is in feet and t is the time in second.


To find the average rate of change of d(t) between 2 seconds and 4 seconds.


From the table we have;


at t = 2 , d(2) = 60


and


at t =4 , d(4) = 240.


Then, by the definition of average rate of change ;


=


Simplify:




therefore, the average rate of change of d(t) between 2 second and 4 second is; 90 ft/s and it represents the average speed of the object between 2 seconds and 4 seconds.

PART A

alligators:

 x = total number of alligators

n = number of years

x=20*1.25^n

crocodiles:

 y = total number of crocodiles

n = number of years

y=25+10n


 PART B

alligators

x=20*1.25^4 = 48.82 round up to 49

crocodiles 25 +10(2) = 25+20 = 45

Part C

 7 years

20(1.25^n)=25+10n

1.25^n=1.25+0.5n

n=7

check:

alligators 20+1.25^7 = 95.36

crocodiles = 25+10(7) = 95
