Answer:

h=7.65

Step-by-step explanation:

h=k√p

k=h/√p

k=5.4/√1.44

k=4.5

h=4.5√p

when p=2.89

h=4.5√2.89

h=7.65

Answer:

H = 7.65

I hope it helps

h \:  =  \sqrt{p}  \\ h \:  = k \sqrt{p} .....(1) \\ when \: h \:  = 5.4 \: p = 1.44 \\ 5.4 = k \:  \sqrt{1.44}

5.4 = 1.2k \\ divide \: both \: sides \: by \: 1.2 \\ k \:  = 4.5

h \:  = 4.5 \sqrt{p}  =  \: formula \: connecting \: h \: and \: p \\ from \: equation \: .....(1) \\ when \: p \:  = 2.89 \: h = \\  when \: p \:  = 2.89 \: h \:  =  \\ h \:  = 4.5 \sqrt{2.89}  \\ h =

h \:  = 4.5 \sqrt{2.89}  \\ h = 4.5 \times 1.7 \\ h \:  = 7.65

Anna71 [15]

The number of guests coming to Doug McDougal party can be calculated to be 23 people.

<h3>What number of people are coming?</h3>

Doug invited 138 guests and out of this, only 1/6 will be coming.

The number of people coming is therefore:

= Number invited x Proportion coming

Solving gives:

= 138 x 1/6

= 23 people

In the X Y -plane, Line crosses the Y - axis at the point (0,3) and passes through the point ( 4,5). Which of the following is a
nikitadnepr [17]

Answer: y = 1/2x + 3

Step-by-step explanation:

Use the equation y=mx +b

Find the slope (m) of the line by finding the difference in y over the difference in x. Or "rise over run".

The y-intercept (b) is 3 (when x is zero, it is y).

Find the volume of the largest rectangular box in the first octant with three faces in the coordinate planes and one vertex in t
makkiz [27]

Answer:

Step-by-step explanation:

x + 2y + 3z = 12

z=\frac{12-x-2y}{3}

Volume = V=f(x,y) = xy(\frac{12-x-2y}{3} )

find partial derivatives using product rule

f_x =\frac{y}{3} (12-2x-2y)\\f_y = \frac{x}{3} (12-x-4y)

i.e.

Using maximum for partial derivatives, we equate first partial derivative to 0.

y=0 or x+y =6

x=0 or x+4y =12

Simplify to get y =2, x = 4

thus critical points are (4,2) (6,0) (0,3)

Of these D the II derivative test gives

D<0 only for (4,2)

Hence maximum volume is when x=4, y=2, z= 4/3

Max volume is = 4(2)(4/3) = 32/3
