-6.4(x-2.25)=19.2 
-6.4*x=-6.4x   -6.4*-2.25=14.4
rewrite
-6.4+14.4=19.2 subtrac 14.4 from both sides 19.2-14.4=4.8 rewrite
-6.4x=4.8 divide -6.4 from both sides 4.8/-6.4=.75
x=0.75

Solve 3y + 11 = - 16​
astra-53 [7]

Answer:

y=-9

Step-by-step explanation:

So we have the equation:

3y+11=-16

To solve for y, subtract 11 from both sides. The left will cancel:

3y=-27

Divide both sides by 3. The left again cancels:

y=-9

So, the answer is -9.

And we're done!

I hope this helps!

The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and decided to go in
Svetllana [295]

Answer:

\frac{dD}{dt}= 181\frac{168}{1600}

Step-by-step explanation:

h= 1000 ft

dx/dt= 232 ft/sec

D= 1600 ft

First, we have to find a distance x ( shown in the figure)

applying pythagorus theorem

D^2= h^2+x^2................1

x^2= D^2-h^2

= 1600^2-1000^2

x^2= 1560000

x=1248.99 m

Now we can find out how fast the aircraft is receding from the trawler

( notice that the height is not changing)

so differentiating equation 1 w.r.t t we get

\frac{d}{dt} (D^2)= \frac{d}{dt}(h^2+x^2)

2DD'= 2hh'+2xx'

D\frac{dD}{dt}= h\frac{dh}{dt}+x\frac{dx}{dt}

now putting values we get

1600\frac{dD}{dt}= 1000\times0+232\times1249

\frac{dD}{dt}= 181\frac{168}{1600}
