The expanded form of 9,540,000 is:
9,540,000 = 9000,000 + 500000 + 40000 + 000 +00 + 0
we can also write it as :
9,540,000 = 9 x 1000000 + 5 x 100000 + 4 x 10000
and using exponents as power of 10 is:
9,540,000 = 9 x 10⁶ + 5 x 10⁵ + 4 x 10⁴
The average speed of the rocket from 3 to 4 seconds after launch is: -40 ft/s
Given the equation as a model, h(t) =–16t² + 72t.
Average speed from 3 to 4 seconds =
<em>Find h(4):</em>
h(t) =–16t² + 72t
- Substitute 4 for t in the equation h(t) =–16t² + 72t
h(4) = -16(4)² + 72(4)
h(4) = -256 + 288
h(4) = 32
<em>Find h(3):</em>
h(t) = -16t² + 72t
- Substitute 3 for t in the equation h(t) =–16t² + 72t
h(3) = -16(3)² + 72(3)
h(3) = -144 + 216
h(3) = 72
Plug in the value into :
average speed from 3 to 4 secs =
Therefore, the average speed of the rocket from 3 to 4 seconds after launch is: -40 ft/s

Answer:
x = √(10) - 2, -√(10) - 2
Step-by-step explanation:
x² + 4x + 4 = 10
factor:
(x + 2)² = 10
take square root of both sides:
x + 2 = ±√(10)
split into 2 equations:
x + 2 = √(10) x + 2 = -√(10)
solve both equations and collect solutions:
x = √(10) - 2, -√(10) - 2
