The number of pies available for sale at the Pie in the Sky Bakery varies over the course of the day, and is given by P(t) = 30 - 212 + 161, where t is the number of hours
since the store opens in the morning. What is the average rate at which this
number changes during the first t hours that the store is open?
a) 30-212 +161
t
b) 30-21 +16
Oc) -4t+16
d) None of these

step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
