Answer:
<h3>dn = -7^n-1</h3>
Step-by-step explanation:
Given the sequence -1,-7,-49,-343,....
We are to find the nth term of the sequence
dn = ar^n-1
a is the first term = -1
r is the common ration = -7/-1 = -49/-7 = 7
n is the number of terms
Substitute
dn = -1(7)^n-1
dn = -7^n-1
hence the nth term of the sequence is dn = -7^n-1
The triangle to solve for has a leg or 12 feet, hypotenuse of 20 feet, so solve for Pythagoras

for a

a = 16 feet
Solution:
Albert's medical expenses is = $ 12,000
Sam's come = $ 8,000
Add the amount = 12000 + 8000 = $ 20000
Sue Jones is insured for the amount = 10/20
Now, find the insurance.
(10/20)*(20,000) = 10000
Hence, $10000 pay for the insurance.
