I graphed it.
Answer:
x=52°
Step-by-step explanation:
38° +90°+x = 180° ( Angles on a straight line)
x+ 128° =180°
x= 180° -128°
x= 52°
Answer: 9
Step-by-step explanation:
3 + x = 14. 14 is the final number and 3 is the first. X is telling us how many more people came after the first three.
Step-by-step explanation:
The problem statement says λ<1. If this is true, then the cannonball is slower than the boat, and it will never reach the boat. So I assume it's actually λ>1.
If we say t is the amount of time, then the boat travels south a distance of ut, and the cannonball travels a distance of λut.
v = λut
ut = v/λ
Using Pythagorean theorem:
d² + (ut)² > v²
d² + (v/λ)² > v²
λ²d² + v² > λ²v²
λ²d² > (λ² − 1) v²
λ² / (λ² − 1) > (v/d)²
