Answer:
The last two terms of the expression are
Both the last terms has variable of degree equal to (2+4=6) and (3+3=6).So, the first term must have degree greater than 6.
Correct Options are
Answer:
B. The charge per kilowatt-hour.
Step-by-step explanation:
We have been given that an electric company charges a certain rate per kilowatt-hour of electricity used and an administrative fee of $3.50. The company charged Zhao $63.25 for using 800 kWh of electricity.
The equation represents the total amount of bill charged by electricity comapany to Zhao for 800 kilowatts of electricity use.
Since total bill is $63.25, administrative fee is $3.50 and total use of electricity is 800 kilowatts, therefore, r represents the charge per kilowatt hour and option B is the correct choice.
Answer: 553.08
Step-by-step explanation:
Answer:
2/7
Step-by-step explanation:
Et's give this a go:h(x) = cos(x) / f(x)
derivative (recall the quotient rule)h'(x) = [ f(x) * (-sin(x)) - cos(x)*f'(x) ] / [ f(x) ]^2
simplifyh'(x) = [ -sin(x)*f(x) - cox(x)*f '(x) ] / [ f(x) ]^2h'(π/3) = [ -sin(π/3)*f(π/3) - cox(π/3)*f '(π/3) ] / [ f(π/3) ]^2h'(π/3) = −(3–√/2)∗(3)−(1/2)∗(−7)/(3)2
h'(π/3) = (−33–√/2+7/2)/9
And you can further simplify if you want, I'll stop there.
