The decimal for 4 5/8 is 4.625 the 4 represents the whole so 5/8 stays the same and you place the 4 in front of .625
Using the given property, we conclude that:
f(4) = 8
<h3>
What is the value of f(4)?</h3>
We know that our function has the property:
5*f(x) = f(5*x)
Now, we also know that:
f(20) = 40
Notice that we can rewrite:
f(20) = f(5*4)
Using the above property, we know that:
f(20) = f(5*4) = 5*f(4) = 40
Using the last part:
5*f(4) = 40
f(4) = 40/5 = 8
f(4) = 8

Answer:
175 ft
Step-by-step explanation:
Let c represent the change in altitude. Then an equation can be written:
150 +c = 325
We solve for c by subtracting 150 from both sides of the equation:
c = 325 -150 = 175
The change in altitude is an increase of 175 feet.
_____
This confirms the general rule that to find the value of a change, you subtract the original value from the new value. Here, that means ...
c = 325 -150 = 175 . . . . as above.
Recursive formula= a(n)=a(1)(n-1)+d
a(n)= 9(n-1)+2
explicit formula= a(n)= a(1)+(n-1)d
a(n)= 9+(n-1)2
12th row= a(12)=9+(12-1)2
a(12)=9+11(2)
a(12)=9+22
a(12)=31
