Need help to solve the maximum

Mathematics

Answer:

B. 1

Step-by-step explanation:

Your answer for A is correct.

The time it take for the sub to hit the water will be the time between when the submarine started to get lowered and when its distance from the water was zero.

The sub started to get lowered at x = 0.

Now we need to solve for the smallest positive zero of the function.

This function factors to (x - 1)(x - 7)

From this we can tell that the submarine is a water level for time x = 1 and x = 7.

The smallest of these is 1, so that is when the submarine first hit the water and 7 is when it came back out.

The sub started getting lowered at x = 0 and hit the water at x = 1 and because x is in seconds, it took 1 second for the sub to hit the water.

Does anyone know how to answer this question I'm having a lot of trouble with it?
Helen [10]

Answer:

h = \frac{2A}{(b+c)}

Step-by-step explanation:

Formula for the area of a trapezoid is,

Area (A) = \frac{1}{2}(b+c)h

Here b and c are the bases and 'h' is the height of the trapezoid.

2A = 2[\frac{1}{2}(b+c)h]

2A = (b + c)h

\frac{2A}{(b+c)}=h

Therefore, formula for the height of the trapezoid will be,

h = \frac{2A}{(b+c)}

Answer:

#1) D.$623.52  ; #2) D.17.1 ; #3) B.II and III ; #4) C.A greater availability of ATM's may make it easier to do bank transactions. Someone may choose this availability over a higher savings interest rate; #5) B.Bank E offers you a chocolate bar for filling out an application for checking and credit at the same time; #6) D.Make purchases or get cash now, and pay back the bank in monthly payments; #7) T; #8) B.Thursday ; #9) B.$1,545.83

Step-by-step explanation:

#1) 6.2% of her gross pay would be

0.062(765) = $47.43.

1.45% of her gross pay would be

0.0145(765) = 11.09

22% of the state tax withheld would be

0.22(68) = 14.96

This means her gross pay would be

765-68-47.43-11.09-14.96 = $623.52

#2) The employee benefits in addition to his gross pay would be

33500-28600 = 4900

This makes it

4900/28600 = 0.17 = 17% of his pay.

#3) Knowing where branches or ATMs are is helpful when choosing a bank.  Additionally knowledge of personal usage habits and needs will help plan where best to bank.

#4) Having more ATMs available makes banking more convenient to some customers, which is more important to some customers than high interest rates.

#5) Having a chocolate bar offered for filling out an application for checking and credit is not a good reason to examine that given bank.

#6) You cannot "borrow" against a traditional checking account and then pay it back later.

#7) An ATM withdrawal is a POS (point of sale) transaction.

#8) At the end of the day Monday, Elizabeth has

252-114.6+150 = $287.40

At the end of Tuesday she has

287.40-79.68 = $207.72

At the end of Wednesday she has

207.72-161.39 = $46.33

At the end of Thursday she has

46.33-57.40 = -11.07

This is her first overdraft.

#9) Adding together the list of items deposited we have

13.50+942.06+75.53+670.14 = 1701.23

Taking out the cash he receives gives us

1701.23-155.40 = $1545.83
