The x value of the vertex for
ax²+bx+c=y is -b/2a
so
y=2x²+12x+22
b=12
a=2
-b/2a=-12/(2*2)=-12/4=-3
that is x value
to find y value, sub the x value for x
-3 for x
y=2(-3)²+12(-3)+22
y=2(9)-36+22
y=18-14

(-3,4) is vertex
The Parkland formula is
V = 4mA
where
V = volume of replacement fluid (mL) required within the first 24 hours after a burn injury,
m = body mass, kg
A = percent of body surface area covered with burns.
The first half of the fluid should be delivered in the first 8 hours.
Because we are concerned with fluid replacement within the first 8 hours, the Parkland formula is valid to be used.
Given:
m = 75 kg
A = 40%
Therefore
V = 4*75*40 = 12,000 mL = 12 L
This is the fluid replacement required in the first 24 hours.
Because half of this amount should be delivered in the first 8 hours, the amount of fluid replacement is
6,000 mL in 8 hours, or
6000/8 = 750 mL per hour.
Answer: 750 mL every hour
Answer:
8,000(1+.09/4) to the 4×9 power
8,000(1.0225) to the 36 power
8,000(2.227816)
answer is $17,822.53
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 
, thus
y = x + c ← is the partial equation
To find c substitute (- 4, - 9) into the partial equation
- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7
y = x - 7 ← equation of line
