Answer:
$5.08
Step-by-step explanation:
Step one:
given data
We are told that a credit card company applies a 6% fee on all transactions under $10
since the cost of coffee bellow $10 that is $4.80, the 6% fee is applicable
so
=6% of 4.80
=6/100*4.80
=0.06*4.8
=$0.288
Step two:
the total fee will be
=0.288+4.80
= $5.08
This can be factored as (x-3)^2, so they are equal
The father is 48 and the son is 20
2*5=10/3
10/3=3.33
two times 5 equals 10
1 times 3 equals 3
10 divided by 3 equals 3.33
Eccentricity = foci / half the length of the major axis
= 3.5 / 14 = 1/4
