Answer:
old town has 150 steps
Step-by-step explanation:
Let the number of steps in the old tower be m
Mathematically, time = distance/speed
In this case, the distance is the number of steps while the speed is the rate of climbing or descending
For climbing, time spent = m/3
For descending time spent = m/2
Since it took her 25 longer when descending;
This means that;
m/2 - m/3 = 25
(3m-2m)/6 = 25
m/6 = 25
m = 6 * 25
m = 150 steps

Answer:
a. domain: {0, 2, 4}, range: {2, 6, 10}
Step-by-step explanation:
The given diagram depicts a function.
Let us define function:
A function is a mapping of inputs to output.
The left ones are the input of the function while the right side values are the output of the function.
The domain of the function is the set of values that are given as input to the function while the outputs are called range.
so, in the given question
The domain is: {0,2,4} and the range is: {2,6,10}
So, Option A is correct ..
<span>Martin deposits $200
in a savings account that earns 5% annual interest.
year interest balance
1 200 * 5% 200(1.05)
2 200(1.05) * 5% 200(1.05)^2
3 200(1.05)^2*5% 200(1.05)^3
y 200(1.05)^y
=> m = 200 (1.05)^y
