<h3>
Answer: D) 5/2</h3>
==================================================
Explanation:
The parabola is symmetric around its vertex. This means that the roots are the same horizontal distance away from the vertex. Furthermore, we can apply the midpoint formula on the given roots to find the x coordinate of the vertex.
Find the midpoint of 2 and 3 to get (2+3)/2 = 5/2
Note: 5/2 = 2.5
Answer:
P(x) =
+ 304x - 8510
x = 37 smallest B.E.P
Step-by-step explanation:
P = R - E
P = + 317 x
E = 13x + 8510
P = + 317 x - 13x - 8510
P(x) = + 304x - 8510
B.E.P.(X) where R=E
+ 304 x - 8510 = 0
2(x-37)(x-115)
Answer:
40 mL of vinegar,
280 mL of dressing
Step-by-step explanation:
Let v = the milliliters ( mL ) of 100% vinegar,
Then it should be that 320 - v = mL of dressing.
v + .12( 320 - v ) = .23( 320 ) - So in this case the mL of vinegar is associated with the percent of vinegar composed. 100 percent is, in other words, 1, and is multiplied by " v " the mL of 100% vinegar. 1 
v is also v, and so is written as such in our equation. 0.12 is the decimal form of the 12% vinegar, associated with the mL of dressing - as the italian dressing is composed of 12% vinegar. 23% is 0.23 in decimal form, multiplied by the mL of of vinegar in the mixture, 320 mL.
Let's solve for the mL of 100% vinegar, subtracting from 320 to receive the mL of dressing,
v + .12( 320 - v ) = .23( 320 ) - Distribute " .12 "
v + 38.4 - 0.12v = .23( 320 ) - Multiply " 0.32 " by " 320 "
v + 38.4 - 0.12v = 73.6 - Combine like terms and add / subtract
0.88v = 35.2 - Divide 0.88 on either side
v = 40 mL of vinegar,
320 - v = 320 - 40 = 280 mL of dressing
Answer:
-7 < x
Name 2 values
0 and 10
Any number greater than -7 will work
Step-by-step explanation:
-4 < 2(x + 5)
Divide each side by 2
-4/2 < 2/2(x + 5)
-2 < (x + 5)
Subtract 5 from each side
-2-5 < x+5-5
-7 < x
Name 2 values
0 and 10
Any number greater than -7 will work
It's very simple. Answer is the VOLUME.
The more water means the more volume. Obviously, if you have a glass of water fully filler and a glass of water half filled.
Volume occupied by half filled is less than fully filled.
So, it is volume.
Boiling point, density and conductivity does not depend on mass.
