~Hello There!~
Anything to a negative power, turns it into 1 over that number.
Therefore ![49^{-\frac{1}{2} } = \frac{1}{49\frac{1}{2} }](https://tex.z-dn.net/?f=49%5E%7B-%5Cfrac%7B1%7D%7B2%7D%20%7D%20%20%3D%20%5Cfrac%7B1%7D%7B49%5Cfrac%7B1%7D%7B2%7D%20%7D)
Anything to the power of a half, means you have to square root it.
Therefore, the first part is now ![\frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D)
When you have a fraction as a power and both numbers are above one:
You must 'root' it by the denominator and put it to the power of the top number.
Therefore, ![\sqrt[3]{64} = 4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%20%3D%204)
= 16
Now we have:
![\frac{1}{7} * 16](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D%20%2A%2016)
Simply divide 16 by 7 to get the answer:
2.285714
However, since it is a long number, you can just leave it as ![\frac{16}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B7%7D)
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

<u>ANSWER: </u>
Jack picked 10 ears of corn. The amount of corn left is
ears of initial corn.
<u>SOLUTION:
</u>
Given, Jack picked 10 ears of corn.
Now the total corn present is 10 ears.
He and two of his sisters ate two each.
Then, remaining corn = 10 ears – eaten corn
= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)
= 10 – 6 = 4
Now, the amount of corn left in fraction is remaining corn divided by initial corn.
Left over corn = ![\frac{remaining corn}{initial corn}](https://tex.z-dn.net/?f=%5Cfrac%7Bremaining%20corn%7D%7Binitial%20corn%7D)
![= \frac{4}{10} = \frac{2}{5}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B4%7D%7B10%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
Hence, the amount of corn left is
ears of initial corn.
1. The function that models this equation is:
Since the value V (x) of the copier depreciates over
time, hence the 500 must be negative, therefore the equation:
V(x) = −500x + 4800
2. The rate of change for the function is:
The rate of change is also equivalent to the slope of the
equation, in this case the slope is equal to:
-$500/1 year
3. The model predicts that the value of the copier after
3 years will be:
Substituting the value of x = 3 to the function gives us:
V(x) = −500 (3) + 4800
V(x) = $3,300
4. The model predicts that the value of the copier after
7 years will be:
Substituting the value of x = 7 to the function gives us:
V(x) = −500 (7) + 4800
V(x) = $1,300
Answer:
The slop is 3/2 as a fraction. So 3 over 2
Step-by-step explanation:
so first you get to point that are on the line and then you see how far apart they are from each other using y and x coordanites.
Answer:
3t-2
Step-by-step explanation:
- Multiply the terms 3t and 2t. You should get 5t.
- Subtract 7 from 5; you should get -2.
- Now, your equation is 3t-2, you're done!
