List the potential solutions to 2 ln x = 4 ln 2 from least to greatest.

svp [43]

We have to find the potential solutions to $2 ln x = 4 ln 2$ from least to greatest.

Using the properties of ln function.

$a \times ln b = ln b^{a}$

Therefore, we get

$ln x^{2} = ln 2^{4}$

$ln x^{2} = ln 16$

taking antilog on both the sides, we get

$x^{2} = 16$

So, $x = \pm 4$

Therefore, the potential solutions to 2 ln x = 4 ln 2 from least to greatest is -4 and 4.

Joseph squares a number and subtracts 8 from the answer. He then divides this result by 7. Finally he adds 12 and the result is

ivanzaharov [21]

Let the number be X, then we find
$( {x}^{2} - 8) \div 7 + 12 = 20$
$( {x}^{2} - 8) \div 7 = 8$
$( {x}^{2} - 8) = 56$
${x}^{2} = 64$
$x = \sqrt{64} \: \: \: \: \: x = - \sqrt{64}$
$x = 8 \: \: \: \: \: x = - 8$

A 32 foot ladder is leaning against a building and forms a 29.37 angle with the ground how far away from the building is the bas

BARSIC [14]

Answer:

the base of the ladder is 27.89 ft away from the building

Step-by-step explanation:

Notice that this situation can be represented with a right angle triangle. The right angle being that made between the ground and the building, the ladder (32 ft long) being the hypotenuse of the triangle, the acute angle of $29.37^o$ being adjacent to the unknown side we are asked about (x). So, we can use the cosine function to solve this:

$cos(\theta)=\frac{adjacent}{hypotenuse} \\cos(29.37^o)=\frac{x}{32\,\,ft}\\32 \,\,cos(29.37^o)\,\,ft=x\\x=27.887\,\,ft$

which rounded to the nearest hundredth gives;

x = 27.89 ft

The product of a number and 3 more than twice the number is 275. Find the number.

Gnom [1K]

Answer:

55

Step-by-step explanation:

if you do 3 times a number, 3x and twice more, 2x , that would be 5x divided by 275 which would be 55.

30 POINTS! Monica paid sales tax of $1.50 when she bought a new bike helmet. if the sales tax rate was 5%, how much did the stor

avanturin [10]

Hmm... well, here ya go.

1.50 ÷ 0.05 = 30
So, the total is $30
As for the tax rate, including the total, it would be $31.50.

Hope I helped.
