Answer: B-A

Step-by-step explanation:

We know that it is -A - (-B)

The negative sign on the A stays as it is, eliminating choices A-B and A+B.

For the sign in front of B, a double negative creates a positive. - (-B) is essentially -1 x -B, which is B. You can check this through your calculator.

Therefore, the answer is -A+B, or B-A. Hope it helps!

A=42°, b=10, c=12. What is the length of a to the nearest tentH

Digiron [165]

The length of a in the triangle to the nearest tenth is 8.1 units.

<h3>How to find side of a triangle?</h3>

The side a of the triangle can be found using cosine formula.

Therefore,

a²= b² + c² - 2bc cos A

a² = 10² + 12² - 2 × 10 × 12 cos 42°

a² = 100 + 144 - 240cos 42

a² = 244 - 178.354758115

a = √65.6453

a = 8.10217871933

a = 8.1

What value must be defined for to remove the discontinuity of this function at ?

olchik [2.2K]

Answer:

Option D. 8

Step-by-step explanation:

we have

$f(x)=\frac{x^{2}-16 }{x-4}$

Remember that

$x^{2}-16 =(x+4)(x-4)$

substitute

$f(x)=\frac{(x+4)(x-4)}{x-4}$

Remove the discontinuity at x=4

Simplify

$f(x)=(x+4)$

Find the value of f(4)

For x=4

$f(4)=(4+4)=8$
