Answer:
C
Step-by-step explanation:
X vertex = (0, - 3)
ax² + bx + c = y
0.x² + b.0 + c = - 3
c = - 3
Then:
The graphic of g(x) is the a one is negative, because the curve is below.
Then:
g(x) = - x² - 3

47.93 is the answer because multiplication and addition
Answer:
1) The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.
2) The solution x=60 represents the total food bill.
These both answers are correct.
Step-by-step explanation:
Since there are 8 group of friends, and the total amount spent by them is $76 including the tip i.e $16.
If x is the food bill our equation can be:
(x+16)/8 = 76/8
Solving the equation
(x+16)/8 = 9.5
x+16= 9.5*8
x= 76 -16
x= 60
The food bill is x=60.
*Hint: The formula for the lateral surface area of a right cone is LA= Πrs
All we have to do is plug in and solve.
LA= Π(3)(5)
LA = 15Π
LA = 47.1238898
The lateral surface area is around 48 inches.
