Answer:

The height of the platform is 65 ft

Step-by-step explanation:

Let

t -----> the time in seconds after the launch of the fireworks from a platform

h(t) ----> the height of a firework in feet

we have

h(t)=-16t^{2}+120t+65

we know that

The height of the platform is when the value of t is equal to zero (y-intercept)

For t=0

h(0)=-16(0)^{2}+120(0)t+65

h(0)=65\ ft

therefore

The height of the platform is 65 ft

Answer:

65 ft

Step-by-step explanation:

We are given that an equation which gives the height of firework

h(t)=-16t^2+120t+65

Where h(t)=Height in feet

t=Time in seconds

Substitute t= 0

h(0)=65 ft

When t= 0 then height of platform =h(0)

Hence, the height of platform=65 ft

Answer: 65 ft

Scrat [10]

Answer:

a = -4.

Step-by-step explanation:

25(√5)^a * (√5) ^3  = 5√5

25*5^a/2 * 5^3/2 = 5*5^1/2

25*5^a/2  = 5*5^1/2 / 5^3/2

25*5^a/2  = 5^1 *5^1/2 / 5^3/2

25*5^a/2 = 5^3/2 / 5^3/2 = 1

5^a/2 =  1/25 = 5^-2

The bases are equal, so

a/2 = -2

a = -4.
