Lapatulllka [165]

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.

Answer:

Step-by-step explanation:

To find the slope 'm' we use 2 points from the line, those are given in the statement:

$x_{1} =2\\y_{1} =5\\\\x_{2} =3/2\\y_{2} =2$

$m=\frac{y_{2} -y_{1} }{x_{2}-x_{1}}$

$m=\frac{2 -5 }{3/2-2}}$

Finally m=6
