Answer:
3sqrt(2) ................
Y = 20x + 7 for instance
then just substitute the values
A ball dropped from the top of the building can be modeled by the function f(t)=-16t^2 + 36 , where t represents time in seconds after the ball was dropped. A bee's flight can be modeled by the function, g(t)=3t+4, where t represents time in seconds after the bee starts the flight.
Step-by-step explanation:
2⁵ˣ = 8ˣ⁺²
2⁵ˣ = (2³)ˣ⁺²
2⁵ˣ = 2³ˣ⁺⁶
5x = 3x + 6
2x = 6
x = 3
Use distance = rate x time
Let "t" be the time it took for you to drive to your parent's house at 60mph.
So 60t would be the distance.
And "t+40" would be the time it took for you to get to your parent's house at 50 mph. And that total distance would be 50(t+40).
Since both the distances are the same, this gives us the equation:
60t = 50(t+40)
Simplify: 60t = 50t + 2000
10t = 2000
t = 200 minutes
Driving at 60 mph for 200 minutes equates to a total distance of 200 miles.
