Answer:

<em>(0, 0) ; 2</em>

Step-by-step explanation:

First answer is marked correctly <em>(0, 0)</em>

Second question:

0.5 = \frac{1}{2}

\frac{1}{2} × \frac{2}{1} = 1 ⇒ \frac{2}{1} = <u><em>2 </em></u><em>is reciprocal</em> to \frac{1}{2}

Answer:

1. (0,0)

2. 2

Step-by-step explanation:

The origin is the middle or the center which is (0,0)

another way to write 0.5 is 1/2 but be careful because it said reciprocal which means you need to flip it over which is 2    

Hope this helps!

Find the x-coordinates where f ' (x)=0 for f(x)=2x+sin(4x) in the interval [0, pi]
MAVERICK [17]

Answer:

The x-coordinate is \dfrac{\pi}{6}[/tex].

Step-by-step explanation:

We are given a function f(x) as:

f(x)=2x+\sin (4x)

Now on differentiating both side with respect to x we get that:

f'(x)=2+4 \cos (4x)

When f'(x)=0

this means that 2+4\cos (4x)=0\\\\4\cos (4x)=-2\\\\\cos(4x)=\dfrac{-1}{2}

Hence, cosine function takes the negative value in second and third quadrant but we have to only find the value in the interval [0,\pi].

also we know that \cos (\dfrac{2\pi}{3})=\dfrac{-1}{2}----(1) (which lie in the second quadrant)

so on comparing our equation with equation (1) we obtain:

4x=\dfrac{2\pi}{3}\\\\x=\dfrac{\pi}{6}

Hence, the x-coordinates where f'(x)=0 for f(x)=2x+\sin(4x) is \dfrac{\pi}{6}.

Six plus -2 times a number is the same as 26 plus six times the same number.
aleksandr82 [10.1K]

Step-by-step explanation:

let the number be x

and according to question,

six + 2 times a number = 2x + 6

26 + 6 times a number = 6x + 26

→ 2x + 6 = 6x + 26

→ -6x + 2x = 26 - 6

→ -4x = 20

→ x = 20/4 = 5

→ x = 5

therefore, the number is 5.

hope this answer helps you dear...take care and may u have a great day ahead!
