m=18 when r = 2.
Step-by-step explanation:
Given,
m∝![\frac{1}{r}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Br%7D)
So,
m = k×
,--------eq 1, here k is the constant.
To find the value of m when r = 2
At first we need to find the value of k
Solution
Now,
Putting the values of m=9 and r = 4 in eq 1 we get,
9 = ![\frac{k}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bk%7D%7B4%7D)
or, k = 36
So, eq 1 can be written as m= ![\frac{36}{r}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7Br%7D)
Now, we put r =2
m = ![\frac{36}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B2%7D)
or, m= 18
Hence,
m=18 when r = 2.
Answer:
Step-by-step explanation:
You've typed the equation incorrectly. 3^5x-1 = 3⁵x-1.
It needs to be typed as 3^(5x-1) = 7.
Answer:
The price per pound of bananas is $0.5 and the price per pound of apples is $0.6
Step-by-step explanation:
Let
x -----> the price per pound of bananas
y -----> the price per pound of apples
we know that
12x+10y=12 -----> equation A
8x+5y=7 ----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
The intersection point is (0.5,0.6)
see the attached figure
therefore
The price per pound of bananas is $0.5
The price per pound of apples is $0.6
