Hello!

To solve for x, we just multiply both sides by 20.

x≤ -4/5(20)

x≤-16

Therefore, our answer is $\boxed {D) x \leq -16}$

I hope this helps!

An airplane is flying at a speed of 500 mi/h at an altitude of one mile. The plane passes directly above a radar station at time

d1i1m1o1n [39]

Answer:

a) $s=\sqrt{1+d^2}$

b)d(t)=500t

c) $s(t) =\sqrt{1+250000t^2}$

Step-by-step explanation:

d = Horizontal distance

s = the distance between the plane and the radar station

The horizontal distance (d), the one mile altitude, and s form a right triangle.

So, use Pythagoras theorem

$Hypotenuse^2=Perpendicular^2+Base^2$

$s^2=1^2+d^2$

a) $s=\sqrt{1+d^2}$

(b) Express d as a function of the time t (in hours) that the plane has flown.

$distance = speed \times time$

d(t)=500t

$s(t) =\sqrt{1+d^2}$

using b

$s(t) =\sqrt{1+(500t)^2}\\s(t) =\sqrt{1+250000t^2}$

Which of the models show 1.28 ÷ 4?

Talja [164]

Answer:

1.28 ÷ 4 = 0.32

But the "models" make little or no sense. I can see the three bars and two dots representing the digits 3 and 2, but that is the only image I see, repeated three times. It also shows no reference to the decimal place, so I would say there is no real representation of it all.
