Answer:

^ added to a number (like this: 2^2) It means that you have to multiply [2] by itself twice. So it's 2 x 2=4. And if it's 2^3 you multiply [2] 3 times, it's: 2 x 2 x 2=8

Hope this helps! :D

How to find the general solution to y"'+2y"-4y'-8y=0?

S_A_V [24]

$y'''+2y''-4y'-8y=0$

has characteristic equation

$r^3+2r^2-4r-8=r^2(r+2)-4(r+2)=(r^2-4)(r+2)=(r-2)(r+2)^2=0$

which has roots at $r=\pm2$ . The negative root has multiplicity 2. So the general solution is

$y=C_1e^{2x}+C_2e^{-2x}+C_3xe^{-2x}$

What is the slope of the line of best fit?

Ierofanga [76]

Step-by-step explanation:

The line passes through the origin and point (30,3)

so, slope of the graph( miles per minute)= 3/30 = 1/10 miles per minute

Or, slope of the graph miles per hour

$= \frac{3}{ \frac{30}{60} } = \frac{3 \times 60}{30} = 6$

Need help with thisss

frozen [14]

Answer:

cos(x) = 0.6

Step-by-step explanation:

First, we need to find UQ.

UQ = UP·cos(y°) = UP·√(1 -sin²(y°)) = (26 cm)√(1 -25/169) = (26 cm)(12/13)

UQ = 24 cm

Then TQ is ...

TQ = 1/3UQ = 1/3(24 cm) = 8 cm

And cos(x°) is ...

cos(x°) = √(1 -sin²(x)) = √(1 -64/100)

cos(x°) = 6/10 = 3/5

cos(x°) = 3/5 = 0.6
