Factor 125x3 + 343y3

Annette [7]

Answer:

(5x + 7y)(25x² - 35xy + 49y²)

Step-by-step explanation:

125x³ + 343y³ ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b² )

125x³ = (5x)³ ⇒ a = 5x

343y³ = (7y)³ ⇒ b = 7y

125x³ + 343y³

= (5x + 7y)((5x)² - (5x × 7y) + (7y)²)

= (5x + 7y)(25x² - 35xy + 49y²) ← in factored form

Find the corresponding effective interest rate for 3% per year compounded continuously?

jeyben [28]

Answer:

3.045%.

Step-by-step explanation:

We are asked to find the corresponding effective interest rate for 3% per year compounded continuously.

We will use effective interest formula to solve our given problem.

$r=e^i-1$ , where,

r = Effective interest rate,

e = Mathematical constant,

r = Interest rate in decimal form.

Let us convert given interest rate in decimal form.

$3\%=\frac{3}{100}=0.03$

Substitute values:

$r=e^{0.03}-1$

$r=1.030454533953517-1$

$r=0.030454533953517$

$r\approx 0.03045$

Convert into percentage:

$0.03045\times 100\%=3.045\%$

Therefore, the corresponding interest rate would be 3.045%.
