Answer:
B. (-r, 0)
Step-by-step explanation:
W is on the x axis, so the y coordinate is 0.
It is also r away from the origin, so the x coordinate is -r
Hope this helps!
The answer is B by inspection, there really isn't any work to show. You could check every wrong answer to prove it's wrong but that's not needed.
<h3><u>The expression gives the number of transistors in a dense integrated circuit in 1979 is:</u></h3>
![y = 5000(1+0.41)^5\\\\or\\\\y = 5000(1.41)^5](https://tex.z-dn.net/?f=y%20%3D%205000%281%2B0.41%29%5E5%5C%5C%5C%5Cor%5C%5C%5C%5Cy%20%3D%205000%281.41%29%5E5)
<em><u>Solution:</u></em>
<em><u>The increasing function is given as:</u></em>
![y = a(1+r)^t](https://tex.z-dn.net/?f=y%20%3D%20a%281%2Br%29%5Et)
Where,
y is the future value
a is the initial value
r is the growth rate
t is the number of years
From given,
a = 5000
![r = 41 \% = \frac{41}{100} = 0.41](https://tex.z-dn.net/?f=r%20%3D%2041%20%5C%25%20%3D%20%5Cfrac%7B41%7D%7B100%7D%20%3D%200.41)
t = 1974 to 1979 = 5 years
<em><u>Substituting the values in formula,</u></em>
![y = 5000(1+0.41)^5\\\\y = 5000(1.41)^5](https://tex.z-dn.net/?f=y%20%3D%205000%281%2B0.41%29%5E5%5C%5C%5C%5Cy%20%3D%205000%281.41%29%5E5)
Thus the expression gives the number of transistors in a dense integrated circuit in 1979 is found
85.80/4=21.45
1 shirt costs $21.45 before sales tax
The answer would be $224972
