Answer:

Step-by-step explanation:

There are several ways to go at this. Perhaps the simplest is to put the expression into your calculator.

Using the rules of exponents, you recognize ...

a^-b = 1/a^b

(a^b)^c = a^(bc)

(a^b)(a^c) = a^(b+c)

So, we can rewrite the expression to be ...

$\displaystyle\frac{1}{2}\cdot\left(\frac{1}{2}\right)^{-5}=2^{-1}\cdot(2^{-1})^-5\\\\=2^{-1}\cdot2^{(-1)(-5)}=2^{-1}\cdot2^5\\\\=2^{-1+5}=2^4=\boxed{16}$

john invested $2000 that earn interest at 4% per annum compounded monthly. two year later the interest rate is 4.50% compounded

Ksju [112]

Answer:

$\$2,369.11$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

Part 1)

$t=2\ years\\ P=\$2,000\\ r=0.04\\n=12$

substitute in the formula above

$A=2,000(1+\frac{0.04}{12})^{12*2}$

$A=2,000(1.0033)^{24}$

$A=\$2,166.29$

Part 2)

$t=2\ years\\ P=\$2,166.29\\ r=0.045\\n=4$

substitute in the formula above

$A=2,166.29(1+\frac{0.045}{4})^{4*2}$

$A=2,166.29(1.01125)^{8}$

$A=\$2,369.11$

Someone help pls -……

uysha [10]

Answer:

d) 35ft

e) 6 seconds

f) 250°

Step-by-step explanation:

If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.

36 secs = 360°

⇒ 1 sec = 360/36 = 10°

d) After 9 seconds, it has turned:

9 x 10 = 90°

Therefore, it will be 15 + 20 = 35ft from the wall

e) 60° = 6 seconds

f) 25 seconds = 25 x 10 = 250°
