What is the radian value of arccos(-3/sqrt(2))?

Mathematics
1 answer:
Ksju [112]3 years ago
3 0

Answer:

Not defined over the real numbers

Step-by-step explanation:

Let

x = arc \cos( \frac{ - 3}{ \sqrt{2} })

This implies that:

\cos(x)  =  \frac{ - 3}{ \sqrt{2} }

This implies that:

\cos(x) =  - 2.12

The range of the cosine function is -1≤y≤1

Therefore

arc \cos( \frac{ - 3}{ \sqrt{2} })

is not defined for over the real numbers.

B(x)=x+4, what is b(-10)
vovikov84 [41]

Answer:

B(-10)=-6

Step-by-step explanation:

we have

B(x)=x+4

we know that

B(-10) is the value of the function B(x) for the value of x=-10

so

substitute the value of x=-10 in the function

B(-10)=-10+4=-6

therefore

B(-10)=-6

Which absolute value function has a graph that is wider than the parent function, f(x) = |x|, and is translated to the right 2 u
RoseWind [281]

Transformation involves changing the form of a function.

The absolute value function is f(x)=0.3|x -2|

The parent function of the absolute value function is:

f(x)=|x|

When the function is translated 2 units to the right, the new function is:

f(x)=|x -2|

From the function to be wider than the absolute function, the function must be stretched by a factor less than 1.

The possible function from the list of given options is f(x)=0.3|x -2|

Amanda's parents had a birthday dinner for her at Sushi Yama restaurant. The bill came to $74 before the tip. They left an 18% t
Vika [28.1K]

Answer:

<h2>$87.32</h2>

Step-by-step explanation:

Step one:

given data

we are told that the initial bill is $74

thereafter they gave a tip worth 18% of the bill

let us compute what 18% of $74 will amount to

Step two:

=18/100*74

=0.18*74

=$13.32

The added expenses is $13.32

Hence the total cost is

the initial bill plus the tip

=74+13.32

=$87.32

Write an equation or inequality to represent the scenario:
aniked [119]
<h3><u>The value of x is equal to 1.</u></h3><h3><u>6(x + 2) = 20x - 2</u></h3>

<em><u>Distributive property.</u></em>

6x + 12 = 20x - 2

<em><u>Add 2 to both sides.</u></em>

6x + 14 = 20x

<em><u>Subtract 16x from both sides.</u></em>

14 = 14x

<em><u>Divide both sides by x.</u></em>

x = 1
