Solve for x x^3 - 3x = 0

artcher [175]

Answer:

x^3-3x=0

+3x

x^3=3x

ok so that means that that number cubed is the same as a number squared so

x = 0

x = -sqrt(3)

x = sqrt(3)

im going say the answer is mostly likely 0 but it could be the other ones

Hope This Helps!!!

Answer:

x = 0.25

Step-by-step explanation:

When logs are added together, they are actually multiplied and then the logs taken of the product.

That sentence is actually correct, but you are going to have to read it a couple of times. You might understand it if I actually just solve the problem.

ln(2x) + ln(2) = 0 Combine the two subjects to make 1 ln.

ln (2)(2x) = 0 Now take the antilog

ln(4x) = 0

antilog ln(4x) = e^0 e^0 = 1

4x = 1 See your last problem.

x = 1/4

Now the question is "What's the answer?" It might be 1/4 but I doubt it. A better choice would be x = 1/4 or x = 0.25

I'd try the last one first.

A. Explain why the point (100,2) is on the graph.

Crazy boy [7]

Answer:

the log function is the "inverse" function of an exponential function

by definition $log_{a} b = c$ then $a^{c} = b$

in this problem you have $log_{10} 100$

thus what x solves this ? $10^{x} = 100$ the answer is $10^{2}$

thus (100,2)

B) the x intercept is when y = 0

$10^{0} = 1$

x intercept at (1,0)

C) at 100, the curve will hit y = 5000

Consider that an = 4n-1 represents a sequence. What is the tenth term? A) 361 B) 512 C) 1,024 D) 4,096 E) 262,144

mel-nik [20]

Hello from MrBillDoesMath!

Answer:

Choice E.

Discussion:

Assuming that n >=1, a(n) = 4n -1, then

a(10) = 4(10) - 1 = 39

but that doesn't match any of the answers...... hmm...

BUT

If you meant that a(n) = 4^(n-1), then

a(10) = 4^(10-1) = 4^9 = 262144

which is Choice E.

Thank you,

MrB

Answer:

Jennifer's height is 63.7 inches.

Step-by-step explanation:

Let X = heights of adult women in the United States.

The random variable X is normally distributed with mean, μ = 65 inches and standard deviation σ = 2.4 inches.

To compute the probability of a normal random variable we first need to convert the raw score to a standardized score or z-score.

The standardized score of a raw score X is:

$z=\frac{X-\mu}{\sigma}$

These standardized scores follows a normal distribution with mean 0 and variance 1.

It is provided that Jennifer is taller than 70% of the population of U.S. women.

Let Jennifer's height be denoted by x.

Then according to the information given:

P (X > x) = 0.70

1 - P (X < x) = 0.70

P (X < x) = 0.30

⇒ P (Z < z) = 0.30

The z-score related to the probability above is:

z = -0.5244

*Use a z-table.

Compute the value of x as follows:

$z=\frac{X-\mu}{\sigma}$

$-0.5244=\frac{x-65}{2.4}$

$x=65-(0.5244\times 2.4)$

$=63.7414\\\approx63.7$

Thus, Jennifer's height is 63.7 inches.
