Answer:
<u>Frequency = 1/period = 
</u>
Step-by-step explanation:
The frequency of the sinusoidal function = 1/period
Frequency is how many the function repeats itself per unit if time i.e: per "1"
For the given graph :
, Where: B = 2π/period
period = 2π/B , B = 1/4 = 0.25
∴ Period = 2π/0.25 = 8π
∴ Frequency = 1/period =
I think its 160 because if its 5 or more round up if 4 or less round down so 164 the 4 is less so its 160
Answer:
x=8.5
Step-by-step explanation:
To solve this equation, we want to find out what x is. To do this, we need to get x by itself.
Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.
4(x-5)=14
4 is being multiplied by x-5. The opposite of multiplication is division. Divide both sides by 4.
4(x-5)/4=14/4
x-5=14/4
x-5=3.5
5 is being subtracted from x. The opposite of subtraction is addition. Add 5 to both sides.
x-5+5=3.5+5
x=3.5+5
x=8.5
Let's check our solution. Plug 8.5 in for x in the original equation.
4(x-5)=14
4(8.5-5)=14
4(3.5)=14
14=14
Both sides of the equation are the same, so we know our solution, <u>x=8.5 </u>is correct.
It's 12 and 60
Call (n) is the first piece of wooden, so the second piece of wooden is 5n.
=> n + 5n = 72
=> 6n = 72
=> n = 12
The first piece is 12 and the second piece is 60.
