Answer and Explanation:
He rate at which the innovation spread through the community is the number of people proportional to the people adopted it and the people who don't adopted it as constant of proportionality is k , and the fixed population of the community is n.
Suppose
Number of people who have adopted innovation at time t = x (t)
Number of people who don’t adopted innovation at time t = n – x (t)
Then the differential equation is:
dx/dt = kx (n-x), k > 0
Where k is the constant of proportionality.
50% were invested in land, 10% were invested in stocks and 20% were invested in bonds.
Based on this, the total percentage of investments can be calculated as follows:
percentage of investments = 50% + 10% + 20% = 80%
The remaining percentage that was put into a saving account can be calculated as follows:
percentage of money in saving account = 100% - 80% = 20%
Now we know that the remaining is $35,000 represent the 20% of his money.
Assume his total amount of money is m, therefore:
20% x m = 35000
0.2m = 35,000
m = (35,000) / 0.2 = 175,000
Based on this, <span>the total amount of money that Mr. Rodriguez saves and invests is $175,000</span>
Answer:
Step-by-step explanation:
they have given you three points P1 , P2 and P3. We only need two of them, any two will work
P1= (x1, y1) = (-1,8)
P2=(x2,y2) = (3,-4)
now use the slope formula to find the slope , use the variable 'm' for slope since that a very commonly used variable letter for slope
m = ( y2 - y1 ) / ( x2 - x1 )
m = (-4 - 8 ) / ( 3 - (-1) )
m = (-12) / 3 + 1 )
m = -12 / 4
m = - 3
there is your slope, got it? send a note if you have other questions :)
