The temperature at a state park for one day in June can be approximated by the function T(x) = 0.289x2 - 5.202x + 83 0 ≤ x ≤ 18 where T is degrees Fahrenheit and x is the number of hours after 5 PM on Friday. At what time is the temperature lowest? Round to the nearest hour

step-by-step explanation:

how many centimeters did the level of the salsa go down by?

question:

could we have options?

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.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
