In Cincinnati, fireworks are launched from a large barge on the Ohio River for a Labor Day celebration. Their flight can be modeled by the function h(t) = -4.9(t - 4)2 + 80, where h is the height in meters and t is the time in seconds. Suppose that buildings obstruct the fireworks. So, the barge is relocated 30 meters to the east. Write a function to model the path of the fireworks in the new location.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368

(4x+15)^2

step-by-step explanation:

factor using the perfect square rule

16 b

17 d

step-by-step explanation:

16.

amount = 3250(1.06) ^3.5 = 3985.23

17.

m = 9pn

divide both sides by 9n: -

p = m/9n
