[HELP!! GIVING 40 POINTS]Consider the function f(x)=2x+6, create a situation that would model this function.
1 answer:
(Above is the graph for the line)
Situation:
You are signing up for a book club. The get-in price is 6. Every month, you have to pay 2 dollars.
How This Works:
y=mx+b
M=Slope
B=y intercept.
Y intercept is the starting point. The beginning out. In this case, the y intercept is 6. So, in our situation, 6 is the joining fee. The beginning amount. Slope is the the rate of change. The slope in this problem is 2. Since the monthly fee is 2, that would make it the slope

b.
Step-by-step explanation:
We have a differential equation
y''-2 y'-35 y=0
Auxillary equation
By factorization method we are finding the solution
Substitute each factor equal to zero
D-7=0 and D+5=0
D=7 and D=-5
Therefore ,
General solution is
Let
We have to find Wronskian
Substitute values then we get
a.
We are given that y(0)=-7 and y'(0)=23
Substitute the value in general solution the we get
....(equation I)
......(equation II)
Equation I is multiply by 5 then we subtract equation II from equation I
Using elimination method we eliminate
Then we get
Substitute the value of in I equation then we get
Hence, the general solution is
b.
Answer:
Ivan gets £90 more than Tanya
Step-by-step explanation:
Given that
Total amount = £150
Ratio: 4:1
First of all we have to find the sum of ratio: 4+1 = 5
Now,
Ivan's Share:
Tanya's Share:
Ivan gets £120 and Tanya gets £30
The difference between their shares is the answer.
So,
Hence,
Ivan gets £90 more than Tanya
