A vat of milk has spilled on a tile floor. The milk flow can be expressed with the function r(t) = 4t, where t represents time i

Likurg_2 [28]

R(t) = 4t
A(r) = π(r^2)

a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)

b) t = 4,

A(4) = 16*3.14*(16)^2 = 12,861.44

How does the graph of y= -(2x+6)^2+3 compare to the graph of a parent function

raketka [301]

Here the list of the transformations applied to the parent function, and their effect:

$x^2 \to (2x)^2=4x^2$ . This causes a horizontal compression of factor 4.
$(2x)^2 \to (2x+6)^2= 4(x+3)^2$ . This causes a horizontal translation, 3 units to the left.
$(2x+6)^2 \to -(2x+6)^2$ . This causes a reflection about the x axis.
$-(2x+6)^2 \to -(2x+6)^2+3$ . This causes a vertical translation, 3 units up

So, if you start from the graph of $y=x^2$ , you have to compress and translate it horizontally, flip it with respect to the x axis, and finally move it up 3 units.
