Your answer is C. 500,000
Answer:
-22.5
Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48
(3-48)/ 0-(-2)
(-45) / 2
-22.5
Answer is 9
A(x)=f(b)-f(a)/b-a
where a=-10 b=10
f(x)= x^2+9x+18
f(a)=(-10)^2-90+18=28
f(b)=208
A(x)=208-28/10+10
A(x)=180/20=9
Answer:

Step-by-step explanation:
From the given figure, it can be seen that
, thus ΔABC is an isosceles triangle.
Therefore,
⇒
Solving the above equation, we get
⇒
⇒
⇒
Now, substituting the value of x in AC, we have
⇒
⇒
⇒
⇒
Thus, the length of the side AC of the given triangle is 25 units.
