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

Hello :
<span> f(x) = -5x² +x+1
</span>a = -5 b = 1 c = 1
the vertex is the point A(-b/2a ; f(-b/2a) )
-b/2a = (-1/-10) = 1/10 = 0.1
f(1/10) = -5(1/10)²+(1/10)+1 =21/20 = 1.05
LC=1
Step-by-step explanation:
f(x)=x^2-8x-4
=(1)x^2-8x-4
