Shen is going to rent a truck for one day. there are two companies he can choose from, and they have the following prices.
company a charges $110 and allows unlimited mileage.
company b has an initial fee of $65 in charges an additional $0.90 for every mile driven.
for what mileages will company a charge less than company b

The mileages for which company A charge less than company B when , y 50 .

Step-by-step explanation:

Given as :

The two truck companies have following prices

Company A

The initial fee = i = $110

And unlimited mileage

Company B

The initial fee = I = $65

Additional charge = $0.90 per mile driven

Let it driven x mile

Let The mileages for which company A charge less than company B = y

Now, According to question

Charges of company A = charges of company B

i.e i = I + 0.90 × x

Or, $110 = $65 + 0.90 × x

Or, $110 - $65 = 0.90 × x

Or, $45 = 0.90 × x

∴    x =

i.e  x = 50

i.e  Company B driven x = 50 miles

So, The mileages for which company A charge less than company B = y

And y x

i.e y 50

Hence, The mileages for which company A charge less than company B when , y 50 . Answer

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
