Answer:
8² = 4² + 5² - 2(4)(5) cos(P)
which is the third option

Explanation:
The general rule of cosine is:
a² = b² + c² - 2bc*cos(A)

In our triangle:
a is substituted by p = 8 cm
b is substituted by n = 4 cm
c is substituted by m = 5 cm
A is substituted by P which we want to find

Replace the variables in the general equation with the givens as follows:
p² = n² + m² - 2mn*cos(P)
8² = 4² + 5² - 2(4)(5) cos(P)

Hope this helps :)

Use the given facts about the functions to find the indicated limit.
oksian1 [2.3K]

Answer: Option b.

Step-by-step explanation:

 1. You can rewrite it as following:

\lim_{x\to \ -6} 2

This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 2, no matter the value of x.

\lim_{x\to \ -6} 2=2

 \lim_{x\to \ -6} 1

 This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 1, no matter the value of x.

\lim_{x\to \ -6} 1=1

2. Then:

\lim_{x\to \ -6} (f/g)(x)=2/1=2

3. The answer 2.

koban [17]

Answer: $700

Step-by-step explanation:

The store is selling at 30% off.

If a mattress is $1,000, first find out what 30% of $1,000 is:

= 1,000 * 30%

= $300

The store is selling 30% off, this means that they are reducing the price by 30%:

= 1,000 - 300

= $700
