Answer:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1
R = laps she runs
s = laps she swims
each r (laps she runs) takes 5 min.
each s (laps she swims) takes 3 min.
She wants to run for 30 min.
So your inequality should = 30
A function is something that lets you work out what something is depending a variable
e.g: x = y + 5
this function states that the unknown x is equal to whatever the variable y is plus 5
1 gallon = $3 so the ratio would be 1:3 where 1 would represent the gallon and 3 the price
