Step-by-step explanation:
Given:
Wavelength of wave : 3.3m
Frequency of wave : 100Hz.
speed/velocity : ?
As we know
velocity = wavelength × Frequency
= 3.3 × 100
=330ms−1
So the speed of the wave is 330 ms·¹
I could be wrong but I’m pretty sure the analysis stage
Let's start by noting the total number of steps traveled was 2825, of which 1700 were taken before going to the store, so we must deduct them from the distance traveled to the store.
X² - 7x - 8 = 0
You can use the Viet theorem
x₁ + x₂ = -p
-1 + x₂ = 7
x₂ = 7+1
x₂ = 8
