Answer: $43,823.37
Step-by-step explanation:
Formula to calculate the accumulated amount earned on principal (P) at rate of interest (r) compounded daily after t years :

As per given , we have
P= $ 30,700
r= 8.9 % = 0.089
t= 4 years

Hence, the amount at the end of 4 years would be $43,823.37 .
Answer:
Distributive Property
Step-by-step explanation:
If the given statement is
5(72 – 3y) = 360– 15y
When we apply the distributive property to the left hand side we get;

When we simplify we get

Therefore the distributive property justifies the given statement.

6 candidates passed physics only
23 students sat in examination
Step-by-step explanation:
Short answer There are
2 places where the graph touches the x axis just as you said.
I take this to mean f(x) = (x - 6)^2*(x + 2)^2
There are two places where the graph touches the x axis but that is not an intercept.
When a graph just touches the x axis, that counts as a root. As the graph shows, these 2 places are
x = 6 and
x = - 2 is where they touch.
If you have a graphing calculator, you can see what this looks like for yourself. The window settings are
x min = - 3
x max = 7
y min = 0
y max = 250.
There is a local maximum between x = -2 and x = 6.
So the answer, once again is at x = -2 and x = 6 and that makes 2 roots for the equation.
