Suppose that an object is dropped from a height of h
meters and hits the ground with a velocity of
v
meters per second. Then
=v19.6h
. If an object is dropped from a height of
15.4
meters, with what velocity does it hit the ground?
Round your answer to the nearest tenth.

Answers

Answer 1

Answer: make hours to seconds to match meters
19.6*3600=70560 seconds
And is dropped from a height of 15.4 meters then the velocity will be
15.4m/70560s = 0.0002182539m/s

Miriam is picking out some movies to rent, and she is primarily interested in comedies and foreign films. She has narrowed down her selections to 10 comedies and 15 foreign films. How many different combinations of 3 movies can she rent if she wants at least two comedies?

Answers

Answer:

There are 795 combinations.

Step-by-step explanation:

The number of ways or combinations in which we can select k element from a group of n elements is given by:

$nCk=(n!)/(k!(n-k)!)$

So, if Miriam want to choose 3 movies with at least two comedies, she have two options: Choose 2 comedies and 1 foreign film or choose 3 comedies.

Then, the number of combinations for every case are:

1. Choose 2 Comedies from the 10 and choose 1 foreign film from 15. This is calculated as:

$10C2*15C1=(10!)/(2!(10-8)!)*(15)/(1!(15-14)!)$

$10C2*15C1=675$

2. Choose 3 Comedies from the 10. This is calculated as:

$10C3=(10!)/(3!(10-3)!)=120$

Therefore, there are 795 combinations and it is calculated as:

675 + 120 = 795

Simplify 2x - 8x - 6y + 9 -14 + x + 11y.

Answers

So once you find the like terms your problem will look like this:
(2x-8x+x)-(6y+11y)+(9-14)
so know you can simply simplify what is in your Parentheses and once that is done it is going to look like this:
(-5x)-(17y)+(-5)
now it looks like that so that would be your answer could you simplified all of the like terms you can't do anything else to the problem!
So again your answer would look like:
(-5x)-(17y)+(-5)
