natka813 [3]
A=P(1+ \frac{r}{n})^{nt}
A=futurer amount
P=present amount
r=rate in decimal
n=number of times compounded per year
t=time in years

A=2500
r=0.05
n=2
t=2

2500=P(1+ \frac{0.05}{2})^{(2)(2)}
2500=P(1+ 0.025)^{4}
2500=P(1.025)^{4}
2500=P(1.025)^{4}
divide both sides by [tex} 1.025^{4} [/tex]

Mr. Blue's first year salary is $30,000 and it doubles each year. What is the explicit rule for the sequence in simplified form?
vekshin1

Mr. Blue' salary is an illustration of a geometric sequence

  • The explicit rule of Mr. Blue 's salary is an = 30000 * 2^(n - 1)
  • The recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000
<h3 /><h3>How to determine the explicit formula?</h3>

Mr. Blue's salary is a geometric sequence with the following parameters:

First term, a1 = 30000

Rate, r = 2

The explicit rule is calculated as:

an = a1 * r^(n - 1)

This gives

an = 30000 * 2^(n - 1)

<h3>How to determine the recursive formula?</h3>

The common ratio is calculated as:

r = an+1/an

Substitute 2 for r

2 = an+1/an

Cross multiply

an+1 = 2an

Hence, the recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000

Pls help i give brainliest
slavikrds [6]

Answer: B no

Step-by-step explanation:

Plot in the x and y coordinates into the equation to solve it.

The x coordinate is  4 and the y coordinate is 1  

-4(4) +3(1)= 2

-16 + 3 = 2

-13 ≠2

-13 does not equal 2 so (4,1) is not a solution.
