Answer:

In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.

What should happen to both sides of the equation to isolate the variable?

LUCKY_DIMON [66]

Answer:

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable

$\boxed{\sf B \ and \ C}$

Step-by-step explanation:

The triangle is a right triangle.

We can use trigonometric functions to solve.

$\sf sin(\theta)=\frac{opposite}{hypotenuse}$

$\sf sin(60)=\frac{5.2}{KL}$

$\sf KL=\frac{5.2}{sin(60)}$

$\sf sin(90-60)=\frac{3}{KL}$

$\sf KL=\frac{3}{sin(90-60)}$

What is 82.375 rounded to the nearist whole number

Mashcka [7]

Just 82 because in order for the number to be 83 it would have to be a 5 after the decimal (82.575= 83). Anything lower than a 5 after the decimal (82.375), would be 82. I hope this helps!

If a finite set S of nonzero vectors spans a vector space V , then some subset of S is a basis for V . True or False

andreyandreev [35.5K]

<h3>Answer: True</h3>

Explanation:

This theorem doesn't have a name unfortunately. So searching it out is a bit tricky if you don't know the right way to word things. Luckily it wasn't too hard of a find, and I managed to track it down in a linear algebra textbook.

Check out the screenshot below for the snippet of the theorem and the corresponding proof. The book simply refers to it as "theorem 1.9", which again, is an unfortunate choice of naming.
