Answer:

Step-by-step explanation:
Soh-cah-toa is a great way to remember:

You just remember the first letters : sine= opposite/hypotenuse , for example.
This is what I get. Total will be 4187.56 with Interest 2187.56.
By using the formula:
To find amount :
A=p (1+r/n)^n×t
Where
P=2000,r=3%,n=1,t=25
So plug in and solve A=2000(1+0.03/1)^1×25
To find interest you use formula A=p+I
A=4187.56, p=2000,i= we need to find.
4187.56=2000+I
4187.56-2000=I
2187.56=i
F(x) = 5 + 2x where x is the number of times he walks the neighbours dog
y-intercept is at y=5 and slope = 2
g(x) :- As x increases by 4 g(x) decreases by -8 so the slope is -8/4 = -2
when x = 0, g(x) = the y intercept is at -1 + (-8/2) = - 5
so equation of g(x) is g(x) = -5 -2x
h(x):- the slope is (3 - 5) / (1 - 0) [ difference in y values / diff in x values]
slope = -2
so we have h(x) = -2x + c where c = the y-intercept
when x = 0 h(x) = 5
so c = 5
h(x) = 5 - 2x
Now j(x)= 2x - 5 - slope is 2 and y intercept = -5
The data set has no association.
