Step-by-step explanation:
<u>__________________________________________________________</u>
<u>FACTS TO KNOW BEFORE SOLVING</u> :-
Lets say there's an expression 
.
It can be also written it as → ![(\sqrt[b]{x} )^{a}](https://tex.z-dn.net/?f=%28%5Csqrt%5Bb%5D%7Bx%7D%20%29%5E%7Ba%7D)
and vice-versa.
<u>__________________________________________________________</u>
Lets come to the question.
- In option A ,
can be also written as ![(\sqrt[7]{7} )^{5}](https://tex.z-dn.net/?f=%28%5Csqrt%5B7%5D%7B7%7D%20%29%5E%7B5%7D)
. But it doesn't match with the other expression given. Hence they are not equivalent expressions.
- In option B ,
can be also written as ![(\sqrt[7]{6} )^{2}](https://tex.z-dn.net/?f=%28%5Csqrt%5B7%5D%7B6%7D%20%29%5E%7B2%7D)
. But it doesn't match with the other expression given. Hence they are not equivalent expressions.
- In option C ,
can be also written as 
. Hence they are equivalent expressions.
- In option D ,
![(\sqrt[4]{81} )^{5}](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B81%7D%20%29%5E%7B5%7D)
can be also written as 
. Hence they are equivalent expressions
Thus , Option C & D are correct.
Answer:
y=-1/2n+44
Step-by-step explanation:
The number of bean stalks, n, represents the x values
The yield, y, represents the y values
After reading the problem, we have two coordinates: (30,29) and (32, 28) Because this problem is asking for y=mn+b, we have to find the slope. How do we find the slope? We do so by using the slope formula y2-y1/x2-x1. Now let's input the coordinates into this formula.
1.) 28-29/32-30 = -1/2
Let's plug -1/2 into y=mn +b
2.) y=-1/2n+b
Now we have to find what b ( y intercept) equals. To find B, we plug a coordinate into x and y. Let's use (30,29)
3.) 29 = -1/2(30)+b
29 = -15 +b
44 = b
We have now found the linear relationship form for this problem: y=-1/2n +44
The change in the temperature will be -1/3 after 3 days
