Answer:
y = -3x² - 24 x + 50
Step-by-step explanation:
y - 2 = - 3(x+4)²
y - 2 = -3(x²+8x+16)
y - 2 = -3x² -24x +48
y = -3x² - 24 x + 50

9² = 12² + 15² - 2 (12) (15) cos (B)
81 = 144 + 225 - 360 cos(B)
81 = 369 - 360 cos (B)
360 cos (B) = 369 - 81
360 cos (B) = 288
cos (B) = 0.8

Answer: Cosine B = 0.8

12² = 15² + 9² - 2 (15)(9) cos (A)
144 = 225 + 81 - 270 Cos A
144 = 306 - 270 Cos A
270 Cos A = 162
Cos A = 3/5 or 0.6

Answer: Cosine Angle A = 3/5
A). 12 ÷ $7.20 = about $1.67 per muffin
b). 8 ÷ $4.40 = about $1.81 per muffin
c). 6 ÷ $4.50 = about $1.33 per muffin
type C costs the least per muffin
Answer:
none of the above the 7^8/8 is equivalent to
Log (5) + log (3) = log (15)
