The material is made of carbon composite since the density of this material is similar to the drone

<h3>What is density?</h3>

Density is mass per unit volume. It is is an important property of a material that helps in saying other features of the material. It also says substance that has more weight as a highly dense substance will have more weight when compared with a less dense substance.

<u>Given data</u>

Initial volume of water = 1000ml

the drone displaced the water to 2290 ml

mass of the drone = 2 kg = 2000 g

<h3>Density of the drone</h3>

volume of the drone equals the volume of water displaced

2290 ml - 1000 ml = 1290 ml

density in g/cm*3

= mass / volume

= 2000 / 1290

= 1.550 g/ml

The density of the drone is similar to density of carbon composite hence the drone of made of carbon composite

Consider the differential equation y'' − y' − 30y = 0. Verify that the functions e−5x and e6x form a fundamental set of solution
Alex Ar [27]

Answer:

Step-by-step explanation:

We have to take the derivatives for both functions and replace in the differential equation. Hence

for y=e^{-5x}:

y(x)=e^{-5x}\\y'(x)=-5e^{-5x}\\y''(x)=25e^{-5x}\\

for y=e^{6x}:

y(x)=e^{6x}\\y'(x)=6e^{6x}\\y''(x)=36e^{6x}\\

Now we replace in the differential equation  y'' − y' − 30y = 0

for y=e^{-5x}:

25e^{-5x}+5e^{-5x}-30e^{-5x}=0\\25+5-30=0

for y=e^{6x}:

36e^{6x}-6e^{6x}-30=0\\36-6+30=0

Now, to know if both function are linearly independent we calculate the Wronskian

W(f,g)=fg'-f'g

W(e^{-5x},e^{6x})=(e^{-5x})(6e^{6x})-(-5e^{-5x})(e^{6x})\neq 0

I hope this is useful for you

Best regard
