a flare is shot straight up from a flare gun, from a height of 6 meters, and with a velocity of 60 m/s. how many seconds it takes for the flare to hit the ground? use the formula below where v0 is the initial velocity and h0 is the initial height. approximately how long will is take the object to hit the ground?
h(t)=−4.9t2+v0t+h0
a. 10.8 sec
b. 11.4 sec
c. 11.8 sec
d. 12.3 sec

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
