Answer:
15 gallons
Step-by-step explanation:
Given that:
Pumping rate is modeled by the equation :
Q(t)=45-t gallons per minute ; where t is in minutes
Number of gallons in tank after 30 minutes ;
Q(t)=45-t
Q(30) = 45 - 30
Q(30) = 15
Hence, Number of gallons in tank after 30 minutes is 15 gallons
Answer: the higher the price is the less competitive the sales
Step-by-step explanation:
say i were to raise a price extremely from $2 to $6 you would buy the other brand of candy that is $2
The range<span> of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the </span>definition<span> means: The </span>range<span> is the resulting y-values we get after substituting all the possible x-values.
for y = log 8x
the range is all real numbers</span>
Use cos2x =1-2sin^2x
1+sinx- (1-2sin^2x) = 1+ sinx -1+2sin^2x
=sinx+2sin^2x=sinx(1+2sinx)
Therefore
Either sinx=0 or 1+ sin2x =0
X=npi or sin2x=-1
Sin2x=sin 3pi/2
2x= npi +(-1)^n3pi/2
x=npi/2 + (-1)^n 3pi/4
Step-by-step explanation:
18÷4= 4.5
because with money there has to be 2 decimal places it has to be $4.50
