Answer:
x = 12
Step-by-step explanation:
__9x__ = __108___
9 9
x = 12
r is the x coordinate and s is the y coordinate. Positive slopes go from lower left to upper right, like going up stairs or up a hill. The line that goes through (r, s) that is positive is line B.
Answer:
Exponential form: y = x^½
Step-by-step explanation:
Given
![log_xy= \frac{1}{2}](https://tex.z-dn.net/?f=log_xy%3D%20%5Cfrac%7B1%7D%7B2%7D)
Required:
The exponential form
To convert to an exponential function, we have to take exponents of both sides using the base of the logarithm function.
This gives us
![x^{log_xy}= x^\frac{1}{2}](https://tex.z-dn.net/?f=x%5E%7Blog_xy%7D%3D%20x%5E%5Cfrac%7B1%7D%7B2%7D)
Since the base of the exponential function and the logarithm is the same (x), they'll cancel out one another
This leaves us with
![y= x^\frac{1}{2}](https://tex.z-dn.net/?f=y%3D%20x%5E%5Cfrac%7B1%7D%7B2%7D)
Hence, the exponential form of the expression
is ![y= x^\frac{1}{2}](https://tex.z-dn.net/?f=y%3D%20x%5E%5Cfrac%7B1%7D%7B2%7D)
Lets use the formula
to solve this, where,
- R is the rate
- W is the number of workers/things
- T is time
- J is number of jobs/things
<em><u>"If it takes 10 seconds for 10 printers to print out 10 pages of paper"</u></em> - here -
W is 10 printers, T is 10 seconds, and J is 10 pages. We can write:
![R(10)(10)=10\\R(100)=10\\R=\frac{10}{100}\\R=0.1](https://tex.z-dn.net/?f=R%2810%29%2810%29%3D10%5C%5CR%28100%29%3D10%5C%5CR%3D%5Cfrac%7B10%7D%7B100%7D%5C%5CR%3D0.1)
<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use
(previously found) to figure out T.</em>
<em>
</em>
So it will take 10 seconds for 50 printers to print 50 pages.
ANSWER: 10 seconds
Answer: x=20°
Explanation: Since UTX is a diameter, it is equal to 180°. You can now set up the equation (4x+2)+x+78=180. Then solve for x.
You should get, x=20.
