Answer:
h = 3589.9 meters ⇒ answer (D)
Step-by-step explanation:
∵ P(h) = P0 . e^(-0.00012h)
∵ P(h) = 65% of P0
∴ 
∴ 
∵ Insert <em>ln</em> in both sides
∴ 
∵<em> </em><em>ln</em>(e) = 1
∴ h = ln(0.65)/-0.00012 = 3589.9 meters
Answer:
sin75º=sin(30)º+45º)
=sin 30 cos 45+cos 30 sin 45
=1/2*√2/2+√3/2*√2/2
=√2/4+√6/4
=(√2+√6)/4
Check with calculator:
sin 75º≈0.9659
exact value=(√2+√6)/4≈0.9659
Answer:
All integers from 2 to six inclusiv
Step-by-step explanation:
One gallon is equivalent to 128 fluid ounces
3 gallons is equivalent to 3*128 fluid ounces
= 384 fluid ounces
One plastic cup can hold 12 guide ounces
So cups needed will be 384/12
32 cups
Answer:
y=1/3x-2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(6-0)
m=(0+2)/6
m=2/6
simplify
m=1/3
y-y1=m(x-x1)
y-(-2)=1/3(x-0)
y+2=1/3(x)
y+2=1/3x
y=1/3x-2
