The function E(d)=0.25d√ approximates the number of seconds it takes a dropped object to fall d feet on Earth. The function J(d)

=0.64⋅E(d) approximates the number of seconds it takes a dropped object to fall d feet on Jupiter. How long (in seconds) does it take a dropped object to fall 50 feet on Jupiter? Round your answer to the nearest hundredth.

Answer:

1.13 seconds

Step-by-step explanation:

step 1

Find out how (in seconds) does it take a dropped object to fall 50 feet on Earth

we have

E(d)=0.25\sqrt{d}

we have

d=50\ ft

substitute

E(50)=0.25\sqrt{50}\ sec

step 2

Find out how (in seconds) does it take a dropped object to fall 50 feet on Jupiter

we have

J(d)=0.64E(d)

For

d=50\ ft

J(50)=0.64E(50)

Remember that

E(50)=0.25\sqrt{50}\ sec

substitute

J(50)=0.64(0.25\sqrt{50})=1.13\ sec

(0,4), (1,0), (2,0), (2,3), (3,1) is it a function

Vas happenin!!

A proper function is when the x value is NOT repeating


This choice is repeating X’s. So it’s not a function


Hope this helps

a random sample of 510 high school students has a normal distribution. The sample mean average ACT exam score was 21 with a 3.2
34kurt

Answer:

CI = 21 ± 0.365

Step-by-step explanation:

The confidence interval is:

CI = x ± SE * CV

where x is the sample mean, SE is the standard error, and CV is the critical value (either t score or z score).

Here, x = 21.

The standard error for a sample mean is:

SE = σ / √n

SE = 3.2 / √510

SE = 0.142

The critical value is looked up in a table or found with a calculator.  But first, we must find the alpha level and the critical probability.

α = 1 - 0.99 = 0.01

p* = 1 - (α/2) = 1 - (0.01/2) = 0.995

Using a calculator or a z-score table:

P(x<z) = 0.995

z = 2.576

Therefore:

CI = 21 ± 0.142 × 2.576

CI = 21 ± 0.365

Round as needed.

The first five terms of an arithmetic sequence are shown below: 20, 17, 14, 11, 8, . . . Let n represent the term number and f(n
Leona [35]

Answer: 17 -3n

Explanation:

In the given arithmetic progression 20,17,14,11,8....

first term that is a = 20

common difference that  is d=  a2-a1 = 17-20 = -3

let n is the nth term

a_{n} = a+(n-1)d

substituting the values of first, common,difference and n

a_{n} =20+(n-1) (-3)

                        = 20 -3n+3

                         =23 -3n
