PLEASE HELP which of the following identities? Check all that apply

alisha [4.7K]

$\sin(x - \pi) = \sin(x) \cos(\pi) - sin(\pi) \cos(x)$
via the angle sum formula of sin
$since \: cos(\pi) = - 1 \: and \: sin(\pi) = 0 \: then \\ sin(x - \pi) = - sin(x) \: which \: proves \: the \: first \: choice$

$\cos(x + y) + cos(x - y) = 2 \cos(x) \cos(y) =\:cos(x + y) + cos(x - y)=cos(x) cos(y)-sin(x)sin(y) +cos(x)cos(y)+sin(x)sin(y)=2cos(x)cos(y)$
which proves the second choice
the third choice is wrong since for x=0,y=0 it will show that 2=1 which is incorrect
for the fourth one you can do some thing similar to choice one just expand the sum formula of sin and that should be true too
so
the first , the second and the fourth are all true

the concentration of a drug in a patient's bloodstream t hours after the drug was administrated presented by the equation c(t) =

Andrews [41]

The graph of the function has no asymptotes.

<h3>The table of values of c(t)</h3>

The function is given as:

c(t) = 5t - t² + 1

When t = 1, 2, 5, 10;

We have:

c(1) = 5(1) - 1² + 1 = 5

c(2) = 5(2) - 2² + 1 = 7

c(5) = 5(5) - 5² + 1 = 1

c(10) = 5(10) - 10² + 1 = -49

So, the table of values is

t c(t)

1 5

2 7

5 1

10 -49

See attachment for the graph of the function

<u>The domain</u>

From the question, we understand that t represents time.

Time cannot be negative i.e. t ≥ 0
The time does not exceed 5.2 i.e. t ≤ 5.2

So, the domain is 0 ≤ t ≤ 5.2

<u>The range</u>

From the graph, the maximum of the graph is 7.25

So, the range is 0 ≤ f(t) ≤ 7.25

<u>Asymptotes</u>

From the graph, we can see that the graph has no asymptotes.

An international company has 13,700 employees in one country. If this represents 21.1% of the company's employees, how many empl

romanna [79]

21.1% of the total company is 13, 700 (as stated in the word problem). Therefore, 0.211x = 13, 700. Divide 0.211 on both sides: 64, 928.9099. The nearest whole number would result in 64, 929 employees.

Answer: 20

Step-by-step explanation:

Let 's complete our quadrilateral to a rectangle ; and subtract from it the area highlighted in red

$\displaystyle \rm S_{\diamond}=6\cdot 5 =30 \\\\ S_{ABCD}=30-(5:2+5:2+5:2+3:2+1\cdot1)=30-(7,5+1,5+1)=\\\\30-10=20 \\\\ S_{ABCD}=20$
