Answer:
60 °F
Step-by-step explanation:
The function can be put into vertex form:
T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms
Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.
T(x) = 0.264(x² -18x +81) +81 -0.264·81
T(x) = 0.264(x -9)² +59.616
The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.
50/2. It equals 25 which isn't a decimal. 50.1 (repeating), 50.1, and the square root of 50 are all decimals.

Answer:
y -5 = 3(x -4)
Step-by-step explanation:
There are many forms of the equation of a line. When the slope and a point are given, the most convenient form is the "point-slope" form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Filling in the given values, we have ...
y -5 = 3(x -4) . . . . . . line with slope 3 through point (4, 5)
