Answer:
y = 15·2.1599^x
Step-by-step explanation:
We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:
b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp
Of course, the coefficient 'a' in the equation is the initial number, 15.
Your exponential equation is ...
y = 15·2.1599^x
a = 15
b = 2.1599
The zeros of the function if they are r1 and r2 the factored form is
f(x)=(x-r1)(x-r2)
so
undistribute -1
f(x)=-1(x-2)(x-(-1))(x-(-2))
3rd degree
so it goes from bottom left to top right
but the -1 flips it so it goes from top left to bottom right
plot the points x=-2, x=-1, and x=2 on x axis
draw a line (curved) that passes through (-2,0) (-1,0) and (2,0) and goes from top left to bottom right
Volume of water in aquarium: LxWxH
16x8x4
=512in3
Volume of stones:
Since the stones displaced 3in of water, you would find the volume by doing 16x8x3 = 384
Therefore the volume of the stones is 384in3
