if log y=3(log 4 + log x), express y in terms of x. serious answers only please no files or nun of that.

Answers

Answer:

The expression is [tex]y = 64 + x^{3}[/tex].

Step-by-step explanation:

Let be [tex]\log y = 3\cdot (\log 4 + \log x)[/tex], the "log" component is refered to logarithms with base 10. By definition of logarithm and its properties, we derive an expression of [tex]y[/tex] in terms of [tex]x[/tex]:

[tex]\log y = 3\cdot (\log 4 + \log x)[/tex]

[tex]10^{\log y} = 10^{3\cdot (\log 4 + \log x)}[/tex]

[tex]y = 10^{3\cdot \log 4}+10^{3\cdot \log x}[/tex]

[tex]y = 10^{\log 4^{3}}+10^{\log x^{3}}[/tex]

[tex]y = 64 + x^{3}[/tex]

The expression is [tex]y = 64 + x^{3}[/tex].

x = 5

Step-by-step explanation:

2x + 5 = 4x - 5  

First you will need to add 5 to each side.

2x + 10 = 4x

Then you need to subtract 2x to each side.

10 = 2x

Lastly, you will need to divide each side by 2.

The temperature was less than -15°C. Write an equality and three possible solution.​

Answers

Answer:

x < -15*C (I can’t make the degrees sign on my iPad, so I put * instead).

3 Possible Answers:

-38*C

-26*C

-57*C

Step-by-step explanation:

Inequality:

x = temperature

< = less than

-15*C = the amount the temperature was less than

3 Possible Outcomes:

Because the temperature is less than -15*C, it can literally be any number that is farther down the number line. Because it’s a negative number, anything like -14, -13, -12, and so on would actually have a greater value (think of it as in being less in debtm or in this case, less below zero). Instead, you’ll do any number like -16, -17, -18, and so on. You can even do a decimal number, like -19.5. I hope this makes sense to you!

Topografía. La superficie de una montaña se modela mediante la ecuación ℎ(, ) = 5000 − 0.001 2 − 0.004 2 . Un montañista se encuentra en el punto (500, 300, 4390). ¿En qué dirección debe moverse para ascender con la mayor rapidez?

Answers

Respuesta:

(-1, - 2,4)

Explicación paso a paso:

Dada la función:

ℎ (x, y) = 5000 - 0,001x2 - 0,004y2

Tomando la derivada parcial con respecto a ambas direcciones (xey) se obtiene la dirección del vector de gradiente, donde es posible el movimiento más rápido

H '(x, y) = (dh / dx, dh / dy)

dh / dx = 2 (-0.001x) = - 0.002x

dh / dy = 2 (-0.004y) = - 0.008y

H '(500, 300) = (- 0,002 (500); - 0,008 (300))

H '(500, 300) = (- 1; - 2,4)

Por lo tanto, el montañista ascenderá con la mayor velocidad en el punto (-1, - 2.4)

A manager at a factory finds that in a random sample of 250 watches, 3 are defective. Of the 7,500 watches from which the sample was chosen, about how many watches are not defective?

Answers

Answer: 7410 watches

Step-by-step explanation:

From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:

= 3/250 × 100

= 1.2%

Percentage that's not defective = 100 - 1.2 = 98.8%

Therefore, from the sample of 7500 watches, the number that's not defective will be:

= 98.8% of 7500

= 98.8/100 × 7500

= 7410

Therefore, 7410 watches aren't defective

Find the radius of a circle with an area of 1017.36 in?, Use 3.14 for pi​

Answers

area of a circle = πr², where r = the radius of the circle

We can rearrange the formula to solve for r:

[tex]r=\sqrt{\frac{\mathrm{area}}{\pi}}.[/tex]

Given an area of 1017.36 in² and using 3.14 for our value for π, the radius of our circle would be:

[tex]r=\sqrt{\frac{\mathrm{area}}{\pi}} = \sqrt{\frac{\textrm{1017.36 }\mathrm{in^2}}{3.14}} \\ r = 18 \text{ } \mathrm{in^2}.[/tex]

D.
-768

Answers

Answer:

D

Step-by-step explanation:

The value of 8th term of this sequence is,

⇒ a (8) = - 49,152

What is Geometric sequence?

An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

Given that;

Consider the first four terms of the sequence are,

⇒ -3, -12, -48, -192, . . .

Here, Common ratio is,

⇒ - 12 / - 3

⇒ 4

Thus, The sequence are in Geometric sequence.

Hence, The value of 8th term of this sequence is,

⇒ a (8) = - 3 × (4)⁸⁻¹

⇒ a (8) = - 3 × 4⁷

⇒ a (8) = - 3 × 16,384

⇒ a (8) = - 49,152

Thus, The value of 8th term of this sequence is,

⇒ a (8) = - 49,152
