Answer:

The correct option is option (B).

He would be saving $10,485.75.

Step-by-step explanation:

We know that,

1 cent =$ 0.01.

Geometric sequence:

The first term of the sequence be a and common ratio n, then $n^{th}$ term of the sequence is $T_n=a(r)^{n-1}$ .
The sum of the sequence is

$S_n=\frac{a(r^n-1)}{r-1}$ where r>1

$=\frac{a(1-r^n)}{1-r}$ where r<1

=na where r=1

Here first term(a)= $0.01, r= 2 , n=20

$S_n=\frac{0.01(2^{20}-1)}{2-1}$

=10,485.75

He would be saving $10,485.75.

IceJOKER [234]

Answer:

Step-by-step explanation:

y=2x²-5x-7

y=2x+2

2x²-5x-7=2x+2

2x²-7x-9=0

2x²-9x+2x-9=0

x(2x-9)+1(2x-9)=0

(2 x-9)(x+1)=0

x=9/2 ,-1

y=11 ,0

solutions are (9/2,11),(-1,0)
