The equation h(t)=−16t2+120t+65 gives the height of a firework, in feet, t seconds after it is launched from a platform.
what is the height of the platform?
enter your answer in the box.
ft

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

we know that

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

For t=0

therefore

The height of the platform is 65 ft

65 ft

Step-by-step explanation:

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

Where h(t)=Height in feet

t=Time in seconds

Substitute t= 0

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

Hence, the height of platform=65 ft

65 ft

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
