Answer:

okay let's start

Step-by-step explanation:

use \: sine \: rule \\  \frac{x}{ \sin(31) }  =  \frac{42}{ \sin(59) }  \:  \: taking \: angle \: at \: c \: as \: 90 \\ x =  \frac{ 42 \sin(31)}{ \sin(59)} \\ x = 25.236146

Which expressions are equivalent to the one below? Check all that apply. <br><br> 9^x
AveGali [126]

Answer:

A) 3^{x}*3^{x}

B) 3^{2x}

C) (3 * 3)^{x}

Step-by-step explanation:

Given the exponential expression, 9^{x}:

A)  3^{x}*3^{x} is equivalent to 9^{x} due to the Product Rule of exponents:  a^{m} a^{n} = a^{m + n}.  

  • 3^{x}*3^{x} = 3^{x+x} = 3^{2x}

Next, apply the Power-to-Power Rule of exponents:  a^{mn} = (a^{m} )^{n}.  

  • 3^{x}*3^{x} = 3^{x+x} = 3^{2x} = (3^{2})^{x}  = 9^{x}

B)   3^{2x}  is equivalent to 9^{x} due to the Power-to-Power Rule of exponents:  a^{mn} = (a^{m} )^{n}.  

  • 3^{2x} = (3^{2})^{x} = (9)^{x} = 9^{x}.    

C)  (3 * 3)^{x}  is equivalent to 9^{x} due to the Product-to-Power Rule of exponents:  (ab)^{m} = a^{m} b^{m}.  

  • (3 * 3)^{x} = (9)^{x}  = 9^{x}

Edna decided to purchase a $15,000 MSRP vehicle at a 5% interest rate for 3 years. The dealership offered her a $1500 cash-back
Ad libitum [116K]
P = A/D, Where P = Monthly payments, A = Total amount owed = 15,000-1,500 = $13,500,

D= \frac{( 1+ \frac{r}{12} )^{nt} -1}{ \frac{r}{12} (1+  \frac{r}{12}) ^{nt} }

r = 5% = 0.05, nt = 12*3 = 36

Therefore,
D = \frac{(1+ 0.05/12)^{36}-1 }{(0.05/12)(1+0.05/12)^{36} } = 33.37

Then,

P = 13,500/44.37 = $404.61
The correct answer is c.
