Name the ordered pair that corresponds to an angle of a pi radians
olga2289 [7]

Answer:

3π (540°) and 5π(900°)

Step-by-step explanation:

π radian = 180° degree

in the trigonimitrical cercle each point is taken by many values

so π position is also -π position

to move from π to -π you should move 360° (wich is 2π) backwards

π-2π = π

so  -π = π +2π

you can get as much as you can of values similar to π using the formula :

π + 2*k*π where k is a relative number

  • k=1

π+ 2*1*π = 3π

  • k=2

π+2*2*π = 5π

3π is 540°

5π is 900°

Derivative of (2x+5)^4(5x+2)^-2
Sveta_85 [38]
Use chain rule

\frac{d}{dx}f(x)g(x)=f'(x)g(x)+g'(x)f(x)

and also power rule
\frac{d}{dx} x^m=mx^{m-1}

so

well, we will say f(x)=(2x+5)^4 and g(x)=(5x+2)^{-2}
f'(x)=4(2x+5)^3(\frac{d}{dy}(2x+5))=4(2x+5)^3(2)=8(2x+5)^3
g'(x)=-2(5x+2)^{-3}(\frac{d}{dx}(5x+2))=-2(5x+2)^{-3}(5)=-10(5x+2)^{-3}


so
\frac{d}{dx}(2x+5)^4(5x+2)^{-2}=8(2x+5)^3(5x+2)^{-2}+(-10(5x+2)^{-3})(2x+5)^4)

#3: A home security company provides security systems for $5 per week plus an installation fee. The total fee for 12 weeks of se
Maru [420]

Answer:

The installation fee is $150

Step-by-step explanation:

Ok so we need to see how much of the $210 is the installation fee. So first were going to multiply 5 by 12 which equals 60. So now were going to subtract that from the $210 so that gives us...

$210-$60=$150

I need to find Domain and Range but how do I know when to use brackets or parentheses
german

Answer:

  • Square brackets [ or ] are used when the end point is included.
  • Parentheses ( or ) are used when the end point is not included.

Step-by-step explanation:

The domain is the horizontal extent of the graph. Here, it is from -2 to +3, with -2 included in the domain and +3 not included.

As an inequality, the domain is written ...

  -2 ≤ x < 3

In interval notation, we use a square bracket for the "or equal to" case:

  [-2, 3)

__

The range is the vertical extent of the function. Here, the range extends from -4 (not included) to +5 (included).

As an inequality, the range is written ...

  -4 < y ≤ 5

In interval notation, the range is written using a square bracket for the "or equal to" case:

  (-4, 5]

_____

<em>Comment on infinity</em>

There is no such thing as "equal to infinity" so an infinite limit is always represented in interval notation using a parenthesis.

If g(x) = 7(x2 + 3) - 10 what is the value of g(5)?<br> a. 186<br> b. 206<br> c. 46<br> d. 20
stira [4]

Answer:

a) 186

Step-by-step explanation:

g(x) = 7(x^2 + 3) - 10

g(5) = 7((5)^2 + 3) - 10

g(5) = 7(25 + 3) - 10

g(5) = 7 × 25 + 7 × 3 - 10

g(5) = 175 + 21 - 10

g(5) = 186
