I believe this should help with this question
This is the picture I am not very good at proofs but hopefully someone can solve it.
Answer:
C) f(x)=2(25)x
For question 4: f(x)=4()^x
Step-by-step explanation: The correct answer from the choices listed above is option C. IT would be f(x) = 2(25)x that is an equivalent function to f(x) = 2(5)^2x. You can square directly 5 since it will still follow the rules for exponents.
Answer:
Equation: 1.50x + 10
34
Amount of rides Dan can go on: 16 rides
Step-by-step explanation:
We can represent this situation using this equation:
1.50x + 10
34
The $10 Dan has to pay as admission is the fixed number because it doesn't vary and always remains the same, so no x goes next to 10.
Each ride costs $1.50 so this is the variable number as it changes with how many rides Dan goes on, therefore an x will go next to 1.50 to represent the amount of rides Dan goes on.
Lastly, Dan has $34 to spare, so the amount spent has to be less than or equal 34.
Solve the equation for x to find the greatest amount of rides Dan can go on:
1.50x + 10
34 Subtract 10 from 34
1.50x
24 Divide 24 by 1.50
x
16
So, Dan has enough money to go on 16 rides or less.
Let's check this answer:
1.50(16) + 10
34 Multiply 1.50 by 16
24 + 10
34 Add 24 and 10
34
34
Hope this helps! Good luck and if you have any questions let me know in the comments!
Answer
A. 196,608
Step-by-step explanation:
-12/3 = -4
48 / -12 = -4 and -192 / 48 = -4
This is a geometric sequence with common ratio -4.
an = a1 r^(n -1) so:-
9th term (a9) = 3*(-4)^(9-1)
= 196,608
