Identify two methods a person can use to pay their bills online. Explain the advantages and disadvantages of both methods.

1 answer:

5 0

1) You can pay your bills online using your debit, credit card, or an electronic check. Advantage: you pay when you want and when you are sure you have money in the bank. Disadvantage: you have to remember to pay the bills by the due date.

2) You can set up automatic withdrawal from your bank account to pay your bills. Advantage: once you set it up, you do not have to remember to pay the monthly bills. Disadvantage: if you do not check your checking account balance to be sure there is enough money to cover the bills, your account may go negative.

Hope this helps! :)

A rectangle is drawn so the width is 97 inches longer than the height. If the rectangle's diagonal measurement is 113 inches, fi

inn [45]

Step-by-step explanation:

h = height of rectangle (should be "length", but ok)

w = width of rectangle

w = h + 97

the diagonal of the rectangle is the Hypotenuse (baseline) of a right-angled triangle with the legs being one height and one width side of the rectangle.

so, we use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

diagonal² = h² + (h + 97)² = h² + h² + 2×97h + 97²

113² = 12769 = 2h² + 194h + 9409

3360 = 2h² + 194h

1680 = h² + 97h = (h + 97/2)² - 9409/4

(completing the square)

6720/4 + 9409/4 = (h + 97/2)²

16129/4 = (h + 97/2)²

127/2 = h + 97/2

30/2 = h = 15

the height is 15.0 in

What percent is the change in the price if: a The price was $100 and now it is $1250?

KatRina [158]

Answer:

The increase is 1150.

11.5 times the original value, or 1150% of it. That's a big increase, and I would not buy that thing, whatever it is.

4x + 3y = 6 3x + 5y = -1 Solve the simultaneous equations. y= z=

Kisachek [45]

Answer:

x=3, y= -2

Step-by-step explanation:

Multiplying :

(4x+3y =6)*-3

(3x+5y =-1)*4

-12x -9y= -18

12x+20y= -4

Add the equations

20y-9y = -4-18

11y = -22

y= -22/11 = -2

3x +5* -2= -1

3x -10 = -1

3x = 10-1

x= 9/3 =3

He's using the graduated cylinder method. I think the volume might be between 15 and 20. (It's kind of not obvious...)

Numbers that add to -0.5 and multiply to 1

Oliga [24]

Short Answer
There are two numbers
x1 = -0.25 + 0.9682i <<<< answer 1
x2 = - 0.25 - 0.9582i <<<< answer 2

I take it there are two such numbers.
Let one number = x
Let one number = y

x + y = -0.5
y = - 0.5 - x (1)
xy = 1 (2)

Put equation 1 into equation 2
xy = 1
x(-0.5 - x) = 1
-0.5x - x^2 = 1 Subtract 1 from both sides.
-0.5x - x^2 - 1 = 0 Order these by powers
-x^2 - 0.5x -1 = 0 Multiply though by - 1
x^2 + 0.5x + 1 = 0 Use the quadratic formula to solve this.

$\text{x = }\dfrac{ -b \pm \sqrt{b^{2} - 4ac } }{2a}$

a = 1
b = 0.5
c = 1

$\text{x = }\dfrac{ -0.5 \pm \sqrt{0.5^{2} - 4*1*1 } }{2*1}$

x = [-0.5 +/- sqrt(0.25 - 4)] / 2
x = [-0.5 +/- sqrt(-3.75)] / 2
x = [-0.25 +/- 0.9682i

x1 = -0.25 + 0.9682 i
x2 = -0.25 - 0.9682 i

These two are conjugates. They will add as x1 + x2 = -0.25 - 0.25 = - 0.50.

The complex parts cancel out. Getting them to multiply to 1 will be a little more difficult. I'll do that under the check.

Check
(-0.25 - 0.9682i)(-0.25 + 0.9682i)
Use FOIL
F:-0.25 * -0.25 = 0.0625
O: -0.25*0.9682i
I: +0.25*0.9682i
L: -0.9682i*0.9682i = - 0.9375 i^2 = 0.9375

Notice
The two middle terms (labled "O" and "I" ) cancel out. They are of opposite signs.

The final result is 0.9375 and 0.0625 add up to 1
