Step-by-step explanation:

[tex] = 2(x - 5) ^{2} + 4(x - 5) + 1[/tex]

Now for the first term use the formula :

[tex] {a}^{2} - 2ab + {b}^{2} [/tex]

[tex] = 2( {x}^{2} - 10x + 25) + 4(x - 5) + 1[/tex]

[tex] = 2 {x}^{2} - 20x + 50 + 4x - 20 + 1[/tex]

[tex] = 2 {x}^{2} - 20x + 4x + 50 - 20 + 1[/tex]

[tex] = 2 {x}^{2} - 16x + 31[/tex]

Do you think it would be better to purchase whole onions at $1.99 per pound, and cut them yourself, or purchase pre-sliced onions at $2.99 per pound? Explain your rationale using a cost and portion argument

Answers

The best option is to purchase the onion at $1.99.

What is the cost?

The cost of any item is defined as the amount paid by the consumer to the seller in the replacement of the item.

Here, the cost of whole onions at $1.99 per pound, cut them yourself, and purchase pre-sliced onions at $2.99 per pound.

The loss = $2.99 - $1.99 = $1

You are giving more amount by $1 for the same onion cutting the onion is not a big task you can cut whole onions with a knife in no time.

Hence, purchase onions at $1.99 to save $1.

One week, Charlotte earned $333.00 at her job when she worked for 18 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $425.50?

Answers

Step-by-step explanation:

$333 for 18 hours work.

so,

333/18 = $18.50 for a single hour.

how many hours to make $425.50 ?

well, as often as the amount of 1 hour work fits into 425.5 :

425.5 / 18.5 = 23 hours

she will have to work 23 hours to make $425.50.

The number of hours Charlotte has to work the next week to earn $425.50 is 23 hours.

Given that, one week, Charlotte earned $333.00 at her job when she worked for 18 hours.

We need to find how many hours would she have to work the next week to earn $425.50.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, money earned in one hour = 333/18 =$18.5

If she is paid the same hourly wage, to earn $425.50, she has worked for 425.50/18.5 hours

=23 hours

Therefore, the number of hours Charlotte has to work the next week to earn $425.50 is 23 hours.

Answers

Answer:

y = 3x - 1 .

Step-by-step explanation:

The general  point-slope form is y = mx + c where m = slope and c is the y-intercept

As we are given the slope and one point we first use the point-slope form:

y - y1 = m(x - x1)

y - 5 = 3(x - 2)

y = 3x - 6 + 5

y = 3x - 1   (Answer).

Answers


y=2x+1
3x + y=-9


3x + y=-9 is the same as y=-3x-9

y=2x+1
y=-3x-9

2x+1 = -3x-9

—-add 3x on both sides

5x+1=-9

—-subtract 1 from both sides

5x=-10

—-divide 5 on both sides

5x/5 = -10/5

x = -2

Answer: Let the one leg be=base=16cm

area=1/2×b×h

184=1/2×16×h

8h=184

h=184/8

h=23

so the height (perpendicular)=23cm

(hypotenuse)2=p2+b2

=square root (23×23+16×16)

=square root (785)

therefore, H=28.01cm

What is a normal distribution?

The mean, median, and mode of a completely normal distribution will all have the same value, represented graphically by the top of the curve. The normal distribution is often known as the bell curve because the probability density graph resembles a bell.

The option that is not true for the normal distribution is the value of the mean and the height of the density curve at its lowest are not equal.

Hence, the correct option is C.
