Answer:6.37
Step-by-step explanation:
f(x)= −0.07x²+ 0.42x+ 6.37
1. Find the x-coordinate. x= -(b/2a)
= -(0.42/-0.07) = 6
x=6
2. Find the corresponding y-coordinate.
f(x)= −0.07x²+ 0.42x+ 6.37
substitute x with 6
-0.07(6)²+0.42(6)+6.37
Simplify
-2.52+2.52+6.37=
6.37
Answer:
The price of one reusable bottle is $8.12
Step-by-steetp explanation:
Ms stone wanted to purchase two reusable bottles but discovered she had only ⅝of the Mone and that ⅝ is equal to $ 10.15.
So the cost of what she wants to purchase will be called x.
Mathematically
⅝ * x = 10.15
X = (10.15*8)/5
X = 81.2/5
X= 16.24
The price of the two bottles is $16.24
So the price if one bottle will be calculated as follows.
2 bottles=$ 16.24
One bottle= $16.24/2
One bottle= $8.12
The price of one reusable bottle is $8.12
