Answer correctly please

Paul [167]

Answer:

$\$272,49$

Step-by-step explanation:

7. $\displaystyle /text{The answer makes sense because since the depreciation rate is 15%, we know that we need to use the "exponential decay" formula.}$

6. $\displaystyle /text{After a depreciation rate of 15% for the past 8 years, the stock is now worth approximately $272,49.}$

5. $\displaystyle 1000[0,85]^8 = 272,490525 ≈ \$272,49$

4. $\displaystyle 1000 = a \\ -15\% + 100\% = 1 - r; 85\% = 1 - r \\ 8\:years = time\:[t]$

3. $\displaystyle /text{We need to use the "Exponential Decay" formula} - f(t) = a[1 - r]^t, where a > 0$

2. $\displaystyle /text{How much is the stock worth after a depreciation rate of 15% per year?}$

1. $\displaystyle /text{initial amount: $1000, a depreciation rate of 15%, and a time period of 8 years}$

I am joyous to assist you anytime.

Find a6 for an arithmetic sequence where a1=3x+1 and d=2x+6

abruzzese [7]

Answer:

a₆ = 13x + 31

Step-by-step explanation:

The nth term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

Here a₁ = 3x + 1 and d = 2x + 6 , then

a₆ = 3x + 1 + 5(2x + 6)

= 3x + 1 + 10x + 30

= 13x + 31

Which represents the solution(s) of the graphed system of equations, y = x2 + 2x – 3 and y = x – 1?

aev [14]

Answer:

y = -4/3 x=-1/3

Step-by-step explanation:

y = x2 + 2x – 3 and y = x – 1

y= (y + 1)2 + 2(y + 1) - 3 and x= y+ 1

y= 2y + 2 + 2y +2 and x= y+ 1

-3y = 4 and x= y+ 1

y = -4/3 and x = (-4/3) + 1 = -1/3

x2 is x squared or x multiplied by two
