A batter hits two baseballs with the same force. One hits the ground near third base. The other is a home run out of the park. W

here was there more work done?
The ball that went out of the park shows more work because the force applied was greater.

The ball that hit near third base shows more work because it hit the ground much harder.

The ball that went out of the park shows more work because the distance was greater.

The ball that hit near third base shows more work because the force applied was greater.

It is C or something else? Really need to get this right. Thank you!

It would be c because hitting it out of the park has the greater distance to it .

If the forces are equal, then the amount of work is dependent on the distance od C

Bond [772]

Answer:

z-score for 900 points = -4

Step-by-step explanation:

To find the z scores

z=(x-mean)/standard deviation

so

z=(900-1500)/150

z= -600/150

Keep gettin this one wrong please help

Answer:

30 Nickels and 188 Pennies

Step-by-step explanation:

okay, so to set up the equation first, we have to assign each coin a variable, let's call them p and n:

P= number of pennies

N= number of nickels

the value of a penny is 1 cent, so 1P, and the value of a nickel is 5 cents, so 5N

The problem states that he has 218 coins, meaning that the total number of pennies and nickels adds up to 218:

P + N = 218

the total value of the coins is $3.38, so that would mean that 1P + 5N has to equal $3.38:

1P + 5N = 338

Okay, so now that we have our equations let's solve them using elimination:

we have to get a common coefficient between both equations, so let's multiply our first equation by 5:

P x 5 = 5P

N x 5 = 5N

218 x 5 = 1090

so, now we can solve by elimination:

5P + 5N = 1090

1P + 5N = 338

the N's cancel out:

4P = 752

divide both sides by 4:

P = 188

okay, so if theres a total of 218 coins, subtract 188 from 218:

218 - 188 = 30

so, there are 30 nickels and 188 pennies.

check our work:

5 x 30 = 150

1 × 188 = 188

150 + 188 = 338

338 = 338

I hope this helps! :)

What is the slope of the line passing through the points (−3, 4) and (2, −1) ?
diamong [38]
Hey there!

You can find the slope by using this equation:

\frac{y_2-y_1}{x_2-x_1}

It doesn't matter what order you use the points in as long as the x's and y's are in the right place. 

y_2=-1 \\ y_1=4 \\ x_2=2 \\ x_1=-3

Just plug your numbers into the equation and solve. 

\frac{-1-4}{2-(-3)}
\frac{-5}{5}
-1

The slope is –1. 

Hope this helped you out! :-)

Lubov Fominskaja [6]

Answer:

Multiply the top equation by +7

Step-by-step explanation:

usually I would think that the first step would be multiply the top equation by -2, but that's not an option

A doesn't work, because it just wouldn't help. B can't work either, because we're trying to get rid of an x or y term.
