Use the periodic compound interest formula to solve.
77julia77 [94]

Answer:

$15,539.67

Step-by-step explanation:

Compound Interest Formula

\large \text{$ \sf A=P\left(1+\frac{r}{n}\right)^{nt} $}

where:

  • A = final amount
  • P = principal amount
  • r = interest rate (in decimal form)
  • n = number of times interest applied per time period
  • t = number of time periods elapsed

Given:

  • P = $11,000
  • r = 5.8% = 0.058
  • n = 4 (quarterly)
  • t = 6 years

Substitute the given values into the formula and solve for A:

\implies \sf A=11000\left(1+\frac{0.058}{4}\right)^{(4 \times 6)}

\implies \sf A=11000(1.0145)^{24}

\implies \sf A=15539.67451...

Therefore, the value of the investment after 6 years will be $15,539.67 to the nearest cent.

Hello, I gotta turn it turn in this question today, help!!!!!!
Sladkaya [172]

Answer:

2 or -2

Step-by-step explanation:

If x² - 8x = -12

Step 1

We find x by solving

x² - 8x = -12

We equate to zero

x² - 8x + 12 = 0

We factorise

x² - 6x - 2x + 12 = 0

x(x - 6) -2(x - 6) = 0

(x - 6) (x - 2) = 0

x - 6 = 0, x = 6

x - 2 = 0, x = 2

x = 6 or 2

Step 2

What is x - 4?

When x = 6

= 6 - 4 = 2

When x = 2

= 2 - 4 = -2

Therefore, x - 4 = 2 or -2
