Answer:
y = 4(x + 11)² - 484
Step-by-step explanation:
y = 4x² + 88x
factor the expression
y = 4(x² + 22x)
complete the square
y + ? = 4(x² + 22x + ?)
y + ? = 4(x² + 22x + 121)
add 4 • 121 to the left side
y + 4 • 121 = 4(x² + 22x + 121)
multiply
y + 484 = 4(x² + 22x + 121)
y + 484 = 4(x + 11)²
subtract both sides by 484
y = 4(x + 11)² - 484
Use the formula T(x) = 0.01x2^x
X is the number of days.
T(8) = 0.01 x 2^8
T(8) = 0.01 x 256
T(8) = $2.56
I JUST TOOK THE TEST AND THE ANSWER IS D
.360 or .306
Because 3 is in the tenths place, there is a 0, and 3+6+0= 3+6=9 the sum of all the digits. And it’s a three digit decimal.
