Answer:
C
Step-by-step explanation:
120 x 35% = should make 42
jus report if its not C
Answer:
Step-by-step explanation:
We have given that:
There are 20 alligators in the swamp. Each year, the number of alligators increases by 25%. There are 25 crocodiles in the swamp. Each year, 10 new crocodiles join the swamp
Part A:
According to the above mentioned statement the function for representing the number of alligators and crocodiles in the swap throughout the year is:
Alligators = y=20(1.25)^x (x represents years)
crocodiles: y=10x+25
Part B:
Number of alligators after 4 years in the swap = y=20(1.25)^x
Number of alligators after 4 years in the swap = y=20(1.25)^4
Number of alligators after 4 years in the swap=48.82
This shows that about 48 to 49 alligators will be there in the swap after 4 year
Number of crocodiles after 4 years in the swap = y= 10(4)+25 = 65
Part C:
We will use the graph method to solve this part:
After approximately 7 years, the number of animals of each type will be the same, 95.
Answer:
2x-5= -20
move -5 to the other side
sign changes from -5 to 5
2x-5+5= -20+5
2x= -15
divide by 2 for both sides
2x/2= -15/2
cross out 2 and 2, divide by 2 and 2 and then becomes x
x= -15/2
Answer:
![- 6 \sqrt{2}](https://tex.z-dn.net/?f=%20-%206%20%5Csqrt%7B2%7D%20)
Step-by-step explanation:
simplify
![\sqrt{28800}](https://tex.z-dn.net/?f=%20%5Csqrt%7B28800%7D%20)
to
![120 \sqrt{2}](https://tex.z-dn.net/?f=120%20%5Csqrt%7B2%7D%20)
then
-0.05 × 120 = -6
then we have our answer
-6√2
Answer:
![\displaystyle{f(x+1)=|x-6|-4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7Bf%28x%2B1%29%3D%7Cx-6%7C-4%7D)
Step-by-step explanation:
To evaluate
, substitute
to
so we should have:
![\displaystyle{f(x+1) = |x+1-7|-4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7Bf%28x%2B1%29%20%3D%20%7Cx%2B1-7%7C-4%7D)
Evaluate the expression and finally, we have:
![\displaystyle{f(x+1)=|x-6|-4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7Bf%28x%2B1%29%3D%7Cx-6%7C-4%7D)
