Answer:
The function 
is represented by 
.
Step-by-step explanation:
Statement indicates that atmospheric pressure decreases exponentially when height above sea level is increased. This fact is represented by the following model:
(Eq. 1)
Where:
- Atmospheric pressure at sea level, measured in kilopascals.
-Atmospheric pressure decrease rate, dimensionless.
- Height above sea level, measured in kilometers.
- Current pressure, measured in kilopascals.
If we know that 
and 
, the function is represented by:
Answer:
Answer is 628 cm^3
Step-by-step explanation:
using base area lets find radius
base area=pie*(r)^2
78.50=3.14*r^2
78.50/3.14=r^2
25=r^2
5=r
now using lateral area lets find height
lateral area=2*pie*r*h
251.20=2*3.14*5*h
251.20=31.4*h
251.20/31.4=h
8=h
volume of cylinder=pie*(r)^2*h
=3.14*(5)^2*8
3.14*25*8
=628 cm^3
I think the answer would be C but I am not certain.
Answer:
Bill got more ($1.62) for each pound exchanged than did Gwyll ($1.56).
Step-by-step explanation:
Let's calculate the unit rate in each case, that is, the number of dollars obtained through exchanging one (1) pound for dollars:
Bill:
$729
--------- = $1.62 per pound
£450
Gwyll:
$780
---------- = $1.56 per pound
£500
Bill got more ($1.62) for each pound exchanged than did Gwyll ($1.56).
Solve for x. The multiplicity of a root is the number of times the root appears.
x=-7 (multiplicity of 1)
x=3 (multiplicity of 2)
x=2-i (multiplicity of 1)
x=2+1 (multiplicity of 1)
