Vertex is the tip(sharpest) point of the curve. As you can see the tip of the curve has coordinates x = 1 and y = 3, vertex of curve is (1,3)

The vertex is the point that divides the graph symmetrically and occurs at a local maximum, minimum, or sometimes an inflection point. In this case it is the global maximum at the point (1,3)

2: What is the solution to the system of equations below? 3x+4y=−22x−4y=−8

vampirchik [111]

Answer:

x=-15/2, y=1/8. (-15/2, 1/8).

Step-by-step explanation:

3x+4y=-22

x-4y=-8

------------------

4x=-30

x=-30/4

simplify

x=-15/2

-15/2-4y=-8

4y=-15/2-(-8)

4y=-15/2+8

4y=-15/2+16/2

4y=1/2

y=(1/2)/4

y=(1/2)(1/4)

y=1/8

To determine drug dosages, doctors estimate a person’s body surface area (BSA) (in meters squared) using the formula BSA = √ h m

krok68 [10]

Answer:

Step-by-step explanation:

Given that a person’s body surface area (BSA) (in meters squared) using the formula

$BSA =\frac{\sqrt{hm} }{60}$

We are to calculate the rate of change of BSA with respect to mass for a person of constant height h = 180 from m =70 to m =80

For this we calculate BSA for 80 kg and BSA for 70 kg first

Rate of change = $BSA(80)-BSA(70)$

= $\frac{\sqrt{180*80} }{60} -\frac{\sqrt{180*70} }{60} \\=2-1.871\\=0.129$

i.e. rate of change per 10 kg is 0.129

No BSA does not increase more rapidly
