Answer:
= 5/n + 3
Step-by-step explanation:
Given that:
=5/n+1 × n+1/n+3
Number 1: 5/n+1
Number 2: n+1/n+3
By simplifying the given product in eq1:
=5/n+1 × n+1/n+3
The denominator of first fraction will be cancelled by the numerator of second fraction and will give:
= 5/n + 3
This is the simplified product.
i hope it will help you
Answer:
52
Step-by-step explanation:
Just think of a number that is 3 more than the number in the ones digit
Mad easy bro just look think hard and you’ll figure it out
One of the rules of triangles is that if you have a 45 45 90 angle triangle, the two sides besides the hypotenuse are equal to each other. In this case, one of the sides is equal to x, so other side is equal to x as well. Now, to solve for x, you need to know the Pythagorean theorum:
Both 'a' and 'b' are equal to x, and 'c' is equal to 3, so I'll make the substitutions below:
This can be simplified to:
Now we just solve for x:

Answer:
Speed of the wave in the string will be 3.2 m/sec
Explanation:
We have given frequency in the string fixed at both ends is 80 Hz
Distance between adjacent antipodes is 20 cm
We know that distance between two adjacent anti nodes is equal to half of the wavelength
So \frac{\lambda }{2}=20cm
2
λ
=20cm
\lambda =40cmλ=40cm
We have to find the speed of the wave in the string
Speed is equal to v=\lambda f=0.04\times 80=3.2m/secv=λf=0.04×80=3.2m/sec
So speed of the wave in the string will be 3.2 m/sec
