Answer:

its -6 times 10 to the power of 1

Step-by-step explanation:

You first put the numbers that relate so it will be -3 times 2 and 10 to the power of 4 times 10 to the power of -3, -3 times 2 equal -6 and 10^4 times 10^-3 equal 10 to the power of 1.

Answer:

(-30000) · (\frac{2}{1000\\}) = <u><em>-60</em></u>

Step-by-step explanation:

Base: (-3 · 10⁴) · (2 · 10⁻³)

Simplify the power terms. A make a negative exponent positive, flip it over the fraction bar, it works both ways: (-3 · 10000) · (\frac{2}{10^{3} })

(-3 · 10000) · (\frac{2}{1000})

(-30000) · (0.002)

= -60

An air traffic controller spots two airplanes at the same altitude converging to a point as they fly at right angles to each oth
sattari [20]
They are traveling at right angles to each other so we can say one is traveling north to south and the other west to east.  Then we can say that there positions, y and x are:

y=150-600t  x=200-800t

By using the Pythagorean Theorem we can find the distance between these two planes as a function of time:

d^2=y^2+x^2, using y and x from above

d^2=(150-600t)^2+(200-800t)^2

d^2=22500-180000t+360000t^2+40000-320000t+640000t^2

d^2=1000000t^2-500000t+62500

d=√(1000000t^2-500000t+6250)

So the rate of change is the derivative of d

dd/dt=(1/2)(2000000t-500000)/√(1000000t^2-500000t+6250)

dd/dt=(1000000t-250000)/√(1000000t^2-500000t+6250)

So the rate depends upon t and is not a constant, so for the instantaneous rate you would plug in a specific value of t...

...

To find how much time the controller has to change the airplanes flight path, we only need to solve for when d=0, or even d^2=0...

1000000t^2-500000t+62500=0

6250(16t^2-8t+1)=0

6250(16^2-4t-4t+1)=0

6250(4t(4t-1)-1(4t-1))=0

6250(4t-1)(4t-1)=0

6250(4t-1)^2=0

4t-1=0

4t=1

t=1/4 hr

Well technically, the controller has t<1/4 because at t=1/4 impact will occur :)
