Please help! How did the failure of the League of Nations help contribute to instability in Europe?,

Answers

While the League of Nations was the brainchild of Woodrow Wilson, in an effort to prevent another great war in the post World War I era, Woodrow Wilson did not live long enough to push approval to join the League of Nations through Congress. By refusing to join, Congress insured that there was no influence of the United States on the League and ultimately, the League of Nations was left weak and helpless to influence the behavior of strong European nations. With no way to enforce the decisions that the League made, it ultimately did little more than stir up more resentment.

The radius of a circle is 1 foot. What is the length of a 45 degree arc

Answers

Final answer:

The length of a 45 degree arc on a circle with a radius of 1 foot is π/4 feet.

Explanation:

The length of a 45 degree arc can be calculated using the formula for the circumference of a circle. The formula for the circumference is given by C = 2πr, where r is the radius of the circle. In this case, the radius is given as 1 foot. So, we can plug in the values to calculate the circumference as C = 2π(1) = 2π feet.

To find the length of a 45 degree arc, we need to find the fraction of the circumference that corresponds to a 45 degree angle. Since a full circle is 360 degrees, a 45 degree angle is 45/360 = 1/8 of the circumference. Therefore, the length of a 45 degree arc is 1/8 of the circumference, which is (1/8)(2π) feet.

Simplifying this expression, we get the length of a 45 degree arc as (1/8)(2π) = π/4 feet.

y = 2x3 + x2
y = 3x + 14

y = 2x3 + 4x2 – x + 5
y = –3x2 + 4x + 9

Answers

The answer is y = 2x3 + 4x2 – x + 5 and y = –3x2 + 4x + 9
Roots are both: x=-4, x= -1/2 , x= 1

Proof:

Solve for x over the real numbers:
2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9

Subtract -3 x^2 + 4 x + 9 from both sides:
2 x^3 + 7 x^2 - 5 x - 4 = 0

The left hand side factors into a product with three terms:
(x - 1) (x + 4) (2 x + 1) = 0

Split into three equations:
x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0

Add 1 to both sides:
x = 1 or x + 4 = 0 or 2 x + 1 = 0

Subtract 4 from both sides:
x = 1 or x = -4 or 2 x + 1 = 0

Subtract 1 from both sides:
x = 1 or x = -4 or 2 x = -1

Divide both sides by 2:

How do I answer this equation? -3x+y=12. I'm supposed to find the function for it bt I don't know how. Can you guys help me out please

Answers

Typically when being asked for a function, they want it written in slope intercept form. To find that, you need to solve for y.

You can do this by adding 3x to both sides which would result in y = 3x + 12.

Also, math teachers typically want functions expressed in terms of f(x) instead of y. So, you can replace your y with that to get the final answer of f(x) = 3x + 12.

Answer:

[tex]y=3x+12[/tex]

Step-by-step explanation:

We have been given an equation in standard form [tex]-3x+y=12[/tex]. We are asked to write our given equation as a function.

We know that the function represents a relationship between input and output, where each input gives exactly single output.

To write our given equation as a function we need to convert our given equation into slope-intercept form of equation because in slope-intercept form, there is exactly one y output for each input of x.

[tex]y=mx+b[/tex], where,

m = Slope,

b = The y-intercept.

To convert our given equation into slope-intercept form, we need to get y on left side of our equation.

[tex]-3x+3x+y=3x+12[/tex]

[tex]y=3x+12[/tex]

Now our equation is in form of a function, where each value of x gives exactly one y value.

What is the wavelength of an earthquake wave if it has a speed of 7 km/s and a frequency of 3 Hz?

Answers

500 meters
wavelength = speed / frequency (5000m/s /10Hz)

Answer: Our wavelength will be 2333.3 m.

Step-by-step explanation:

Since we have given that

Wave speed = 7 km/ s

Frequency = 3 Hz

We need to find the wavelength of an earthquake wave:

As we know that :

[tex]Frequency=\dfrac{Wave\ speed}{wavelength}[/tex]

First we convert km/sec to m/sec.

So, 7 km/sec= 7000 m/sec

so, our wavelength becomes

[tex]\dfrac{Wave\ speed}{frequency}\\\\\\=\dfrac{7000\ m/sec}{3\ Hz}\\\\\\=2333.33\ m[/tex]

So, our wavelength will be 2333.3 m.

What are the equations of the horizontal asymptotes of y = (4e^x+7)/(e^x-1) in the xy plane?

Answers

In order to find a horizontal asymptote of a function f(x), you need to calculate
[tex] \lim_{x \to \infty} f(x) [/tex] = n
where n is a finite number.

in your case you have to caculate separately the two limits:

a) [tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 } [/tex] = [tex] \frac{\infty}{\infty} [/tex]

To solve this, you need to regroup eˣ both on the numerator and on the denominator:
[tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = [tex]\lim_{x \to +\infty} \frac{4 e^{x} (1 + \frac{7}{ e^{x} } ) }{ e^{x} ( 1 - \frac{1}{ e^{x} } ) }[/tex]

At this point the two eˣ cancel out and the parenthesis tend to 1, therefore
[tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = 4
Your first horizontal asymptote is y = 4.

b) Let's calcuate now:

[tex]\lim_{x \to -\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = [tex] \lim_{x \to -\infty} \frac{0 + 7}{0 - 1} [/tex] = -7
Therefore your second horizontal asymptote is y = -7

Your answer is, hence, y = 4 and y = -7 are horizontal asymptotes of the given function.

Final answer:

The horizontal asymptotes of the function y = (4e^x+7)/(e^x-1) are y = 4 and y = -7, occurring as x approaches positive and negative infinity respectively.

Explanation:

The equations of the horizontal asymptotes of the given function y = (4e^x+7)/(e^x-1) can be found by analyzing the behavior of the function as x approaches positive or negative infinity. In this function, as x approaches infinity, e^x grows much faster than any constant, so the constants can be considered negligible. Thus, the behavior of the numerator and denominator is dominated by the terms involving e^x. As x tends towards infinity, the function approaches the ratio of the coefficients of e^x, which is 4/1, meaning the horizontal asymptote is y = 4. As x tends towards negative infinity, e^x approaches zero, and the function approaches 7/(-1), so there is also an asymptote at y = -7.

It is given that there is a vertical asymptote at x = -1, where the denominator becomes zero and hence "blows up".

What is the slant height of a square pyramid that has a surface area of 279 square meters and a side length of 9 meters?

Answers

Answer:

l = 11 meters

Step-by-step explanation:

Surface area = s² + 2s*l

Where "l" is the slant height

Given: Surface area = 279 ; side length s = 9

Now plug in these values in the above formula, we get

279 = 9^2 + 2*9*l

279 = 81 + 18*l

18l = 279 - 81

18l = 198

Dividing both sides by 18, we get

l = 198/18

l = 11 meters

Therefore, slant height of the square pyramid = 11 meters

The Mean Absolute Deviation is 17.92.

What is Mean Absolute Deviation?

The average distance between each data value and the mean is known as the mean absolute deviation (MAD) of a data set. A measure of variance in a data set is the mean absolute deviation.

Take the absolute value of each digit in the data set, then deduct the mean. Next, add up the absolute values. The mean absolute deviation is then calculated by dividing the aforementioned sum by the total number of values in the data set.

Given:

Data set: {20, 24, 12, 44, 68}

Mean of the data = (20+ 24+ 12+ 44+ 68)/ 5 = 168/5

= 33.6

Mean Absolute Deviation

= {| 20- 33.6| + |24- 33.6| + |12-33.6| + | 44-33.6| + |68-33.36|} / 5

= (13.6+ 9.6 + 21.6+ 10.4 + 34.4 )/ 5

= 89.6/ 5

The axis of symmetry is the x-coordinate of the vertex; this makes the axis of symmetry for this equation x = -1.

What is the length of z ?

Answers

it's close to six and it's shorter so 5?

Answer:

The length of z is [tex]3\sqrt{3}[/tex] unit

Step-by-step explanation:

First Label the diagram as shown in the attachment:

In right [tex]\triangle ABC[/tex];

first find the value of y:

Use Pythagoras theorem states that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares on the other two sides.

In [tex]\triangle ABC[/tex]

length of AB =6 unit , length of BC =y unit and the length of AC = 3+9 =12 unit

Now, using Pythagoras theorem to get the value of y;

[tex]AB^2+BC^2=AC^2[/tex]

[tex]6^2+y^2=12^2[/tex] or

[tex]36+y^2=144[/tex] or

[tex]y^2=144-36[/tex]=108 or

[tex]y=\sqrt{108}[/tex]

on simplify we get, [tex]y=6\sqrt{3}[/tex] unit

Therefore, the length of BC is [tex]6\sqrt{3}[/tex] unit.

now, in [tex]\triangle BDC[/tex]

using Pythagoras theorem to find the value of z;

[tex]BD^2+CD^2=BC^2[/tex]

Putting the values of BD = z units , BC = [tex]6\sqrt{3}[/tex] unit and DC = 9 units we have,

[tex]z^2+9^2=(6\sqrt{3})^2[/tex] or

[tex]z^2+81=108[/tex] or

Simplify:

[tex]z^2=27[/tex] or

[tex]z=\sqrt{27} = 3 \sqrt{3}[/tex]

Therefore, the value of length z is [tex]3\sqrt{3}[/tex] unit

Dr. Steve is working with a new radioactive substance in his lab. He currently has 64 grams of the substance and knows that it decays at a rate of 25% every hour.

Identify whether this situation represents exponential growth or decay. Then determine the rate of growth or decay, r, and identify the initial amount, A.

Answers

Remember that the general decay equation is:
[tex]y=A(1-r)^{x}[/tex]
where
[tex]y[/tex] is the amount after a time [tex]x[/tex]
[tex]A [/tex] is the initial amount
[tex]r[/tex] is the the decay percent in decimal form

The first ting we are going to do is find [tex]r[/tex] by dividing our decay rate of 25% by 100%: [tex]r= \frac{25}{100} =0.25[/tex].
We also know from our problem that [tex]y=64[/tex]. Lets replace [tex]y[/tex] and [tex]r[/tex] in our formula:
[tex]64=A(1-0.25)^{x} [/tex]
[tex]64=A(0.75)^{x} [/tex]
We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that this situation represents exponential decay.

Now, to find the initial amount, we are going to solve our equation for [tex]A[/tex]:
[tex]64=A(0.75)^{x} [/tex]
[tex]A= \frac{64}{0.75 ^{x} } [/tex]
Notice that [tex]A[/tex] will depend on the number of ours [tex]x[/tex].

Answer:

This situation models exponential decay because the substance decays with time.

The radioactive substance decays at the rate of : 25%
