Answer:

500m

Step-by-step explanation:

Given data

Frequency= 600,000 Hz

Speed= 300,000,000 m/s

We know that the formula for speed is

v=fλ

substitute

300,000,000=600,000λ

λ=300,000,000/600,000

λ=500 m

Hence the wave length is 500m

(f + h)(x) <br> given f(x)= 3x-2x+4, g(x)= 8x-2, h(x)= 3x +2
zheka24 [161]

Answer:

To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.

(f + g)(x) = f (x) + g(x)

= [3x + 2] + [4 – 5x]

= 3x + 2 + 4 – 5x

= 3x – 5x + 2 + 4

= –2x + 6

(f – g)(x) = f (x) – g(x)

= [3x + 2] – [4 – 5x]

= 3x + 2 – 4 + 5x

= 3x + 5x + 2 – 4

= 8x – 2

(f  × g)(x) = [f (x)][g(x)]

= (3x + 2)(4 – 5x)

= 12x + 8 – 15x2 – 10x

= –15x2 + 2x + 8

\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(  

g

f

​  

)(x)=  

g(x)

f(x)

​  

 

= \small{\dfrac{3x+2}{4-5x}}=  

4−5x

3x+2

​  

 

My answer is the neat listing of each of my results, clearly labelled as to which is which.

( f + g ) (x) = –2x + 6

( f – g ) (x) = 8x – 2

( f  × g ) (x) = –15x2 + 2x + 8

\mathbf{\color{purple}{ \left(\small{\dfrac{\mathit{f}}{\mathit{g}}}\right)(\mathit{x}) = \small{\dfrac{3\mathit{x} + 2}{4 - 5\mathit{x}}} }}(  

g

f

​  

)(x)=  

4−5x

3x+2

Solve for x and y in the system of equation<br>y=x²-4x<br>2x-y=2<br>I'll mark brainliest​
Goryan [66]

Step-by-step explanation:

y =  {x}^{2}  - 4x \\ y = x(x - 4) -  -  - (a) \\ 2x - y = 2 \\ y = 2x - 2 \\ y = 2(x - 2) -  -  - (b) \\ (a) = (b) :  \\ x(x - 4) = 2(x - 2) \\  {x}^{2}  - 4x = 2x - 2 \\  {x}^{2}  - 6x + 2 = 0 \\ x = 5.6 \:  \: and \:  \: 0.4 \\ y = 2(5.6 - 2) \:  \: and \:  \: 2(0.4 - 2) \\ y = 7.2 \:  \: and \:  \:  - 3.2

H(n)=63(-1/3)^n Complete the recursive formula of h(n)
taurus [48]

Answer:

h(n+1) = -⅓ h(n), h(0) = 63

Step-by-step explanation:

h(n) = 63 (-⅓)ⁿ

This is a geometric series where the first term is 63 and the common ratio is -⅓.

Therefore, each term is -⅓ of the previous term.

h(n+1) = -⅓ h(n), h(0) = 63.
