If 16*x=1/64, find the value of x

Mathematics

blondinia [14]2 years ago

Answer:

x = - \frac{3}{2}

Step-by-step explanation:

Assuming you mean

16^{x} = \frac{1}{64}

note that 16 = 4² and 64 = 4³ , so

(4^{2} )^{x} = \frac{1}{4^{3} }

4^{2x} = 4^{-3}

Since the bases on both sides are equal, both 4, then equate exponents

2x = - 3 ( divide both sides by 2 )

x = - \frac{3}{2} ( = - 1.5 )

Determine the values of the parameter s for which the system has a unique​ solution, and describe the solution. sx 1 minus 2 sx
JulijaS [17]

Note: The equations written in this questions are not appropriately expressed, however, i will work with hypothetical equations that will enable you to solve any problems of this kind.

Answer:

For the system of equations to be unique, s can take all values except 2 and -2

Step-by-step explanation:

2sx_{1} + 4x_{2} = -3\\2x_{1} + sx_{2} = 4

\left[\begin{array}{ccc}2s&4\\2&s\end{array}\right] \left[\begin{array}{ccc}x_{1} \\x_{2} \end{array}\right] = \left[\begin{array}{ccc}-3 \\6 \end{array}\right]

For the system to have a unique solution, \begin{vmatrix} 2s & 4 \\ 2 & s \end{vmatrix} \neq 0

2s^{2} -8 \neq 0\\2s^{2}\neq 8\\s^{2}\neq 4\\s \neq 2 or -2

An 60 ounce bottle of grape juice contains 33 ounces of water a 50 ounce bottle of cranberry juice has 30 ounces of water which
sp2606 [1]

Answer:

Bottle containing cranberry juice has a greater percent of water.

Step-by-step explanation:

A 60 ounce bottle of grape juice contains 33 ounces of water.

So the percentage of water in the bottle = \frac{\text{Amount of water}}{\text{(Amount of water + juice)}}\times 100

= \frac{33}{60}\times 100

= 55%

Similarly 50 ounces bottle of cranberry juice contains 30 ounces of water.

So the percentage of water in the bottle =  \frac{\text{Amount of water}}{\text{(Amount of water + juice)}}\times 100

= \frac{30}{50}\times 100

= 60%

Therefore, bottle containing cranberry juice has a greater percent of water.
