Answer:

The practical domain for the function f(x) will be [0,5].

Step-by-step explanation:

A model rocket is launched from the ground and its height from the ground is given by f(x), t seconds after its launch.

It is given that the rocket reaches maximum height at t = 2.5 seconds and comes back to the ground after t = 5 seconds.

So, at t = 0 seconds, the rocket was at the ground and hence, t can not be negative and after t = 5 seconds the rocket comes back to the ground and hence, t can not be greater than 5 seconds.

Therefore, the practical domain for the function f(x) i.e. the values of t lies in the interval [0,5]. (Answer)

Answer:

d = 6.1m

n = 7km

Step-by-step explanation:

To find the variables, use tan

⇒ tan = $\frac{opposite}{adjacent}$

finding d:

⇒tan 63 = $\frac{d}{3.1}$

tan of 63 is 1.963

⇒ 1.963 = $\frac{d}{3.1}$

multiply 3.1 on both sides

⇒ 1.963 x 3.1 = $\frac{d}{3.1}$ x 3.1

⇒ 6.0853 = d

round to the nearest tenth:

⇒ 6.0853 = 6.1

finding n:

⇒ tan 45 = $\frac{7}{n}$

tan of 45 is 1

⇒ 1 = $\frac{7}{n}$

multiply 7 on both sides:

⇒ 1 x 7 = $\frac{7}{n}$ x 7

7 = n

Thirty-three percent of all students at a high school like beef stew. Put of three hundred students, forty are selected randomly and asked whether they liked beef stew. If liking beef stew is a success, the probability of a failure for this binomial experiment would be 0.67. The answer would be letter D.
