Beginning in the middle of summer, the average temperature for a certain year in Phoenix could approximately be modeled by the function f(x)=26cos(0.0055πx)+89, where x represents the number of days since the middle of the summer, and f(x) represents the average temperature in degrees Fahrenheit. What was the lowest average temperature in Phoenix that year (approximately)?

a) 63∘F

b) 55∘F

c) 26∘F

d) 89∘F

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer: r there any options?

step-by-step explanation:

idk

step-by-step explanation:

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
