Mathematics

Answer:

x = 23 degrees

Because if you look at diagram x is vertical to angle FBC, and angle FEC and angle EBA are alternate interior angles so they are equal to each other, and AC is a straight line which means it equals to 180 degrees.

4x+65+x = 180

x = 23 degrees

Suppose an isosceles triangle abc has a=pi/4 and b=c=4. What is the length of a^2?
Zanzabum

The law of cosines states that, if \alpha is the angle between sides b and c,

a^2 = b^2+c^2-2bc\cos(\alpha)

So, plugging our values, we have

a^2 = 16+16-2\cdot 4\cdot 4\cdot\cos\left(\dfrac{\pi}{4}\right)

This is equal to

a^2 = 32-32\cdot\dfrac{\sqrt{2}}{2} = 32-16\sqrt{2}

What is the invers function of f(x)=(n+1)^3?
zimovet [89]

Answer:

f^{-1}(x)=\sqrt[3]{x}-1

Step-by-step explanation:

f(x)=(x+1)^3\\\\y=(x+1)^3\\\\x=(y+1)^3\\\\\sqrt[3]{x}=y+1\\\\y=\sqrt[3]{x}-1\\ \\f^{-1}(x)=\sqrt[3]{x}-1

Graphing both inverses, they will be symmetrical about the line y=x.

392 boots. If you divide everything into "sets" of an unknown amount, there are 5 more "sets" of boots than sandals, also known as the 245 boots. So if you divide 245 by 5, you'll get the number of items in a "set". Then just multiply by 8 from the 8:3 ratio. If you check it, it will come out to 392 boots to 147 sandals, which I think is ridiculous since sandals are supposed to come in pairs so  you should never have a odd number. But anyway, 392 - 147 = 245
