The height of a penny dropped from a 64-foot-tall bridge is modeled by the function h=-16t^2+64, where t is the time in seconds and h is the highest of the penny above the lake.Part AComplete the table of values below.
Time(s),t | 0 | 0.5 | 1 | 1.5 | 2 |
-----------------------------------------------------
Height (ft), h | 64 | | | | |
Please tell me how you do the whole things thank yoy

Answer 1

Answer: For a sec, I thought this was AB Calculus with derivatives and second derivatives but it isn't! That's a good thing!

Anyhow, all the problem is asking is to plug in the values of time to find the height.

We see when time is zero, the height is 64 feet. Plug in zero for the "t" variable and you'll get 64 feet.

When the penny has dropped for half a second or 0.5 seconds, we know the "t" variable and plug in that value.

h = -16(.5)^2 + 64.
h = -16(.25) + 64.
h = -4 + 64.
h = 64 feet when the penny has dropped for half a second.

I encouraged student progression when given the knowledge to complete a problem. We know how to complete the rest of the table. Good luck!

8x=2y+5
3x=y+7
what is the solution ?

Answers

Answer: (4.5, 6.5) is your solution

Step-by-step explanation:

You need either the x term or the y term to be the same in both equations so you can eliminate them...

8x=2y+5

6x=2y+14

Now you can subtract the two equations...

2x=9

Divide 9 by 2....

x=4.5 or 4 1/2

Plug in x into one of the original equations to find y...

13.5=y+7

Subtract 7 from 13.5...

6.5=y

A bowler knocks down at least 6 pins 70 percent of the time. Out of 200 rolls, how many times can you predict the bowler will knock down at least 6 pins?

Answers

Since he knocks at least 6 pins 70% of the time.

For 200 rolls:

70% of 200

= (70/100) * 200

= (7/10) * 200

= 140

140 times.

I think that for this you just find 70% of the 200 rolls. So 70% of 200=140. So you predict that the bowler will knock down 6 pins 140 times. To find 70% you will just knock off a zero to find 10% then times it by 7. I hope that this was helpful.

A jar contains 65 coins, all of which are nickels and dimes. The total value of the coins in the jar is $5.40. How many nickels / dimes are in the jar?

Answers

Answer:

43 dimes, 22 nickels

Step-by-step explanation:

n + d = 65....this is just dealing with the total number of coins

0.05n + 0.10d = 5.40....this is dealing with the actual $ amount...nickels are worth 0.05 and dimes are worth 0.10

n + d = 65....n = 65 - d

now we sub that back into our other equation

0.05(65 - d) + 0.10d = 5.40

3.25 - 0.05d + 0.10d = 5.40

-0.05d + 0.10d = 5.40 - 3.25

0.05d = 2.15

d = 2.15 / 0.05

d = 43 <==== 43 dimes

n + d = 65

n + 43 = 65

n = 65 - 43

n = 22 <=== 22 nickels
