Why would the polynomial, "[tex]x^2+5x-24[/tex]" factor out to (x-3)(x+8)?

Answers

Answer 1

Step-by-step explanation:

5x can also be written as " -3x + 8x " so:

[tex]x^2+5x-24 = x^2-3x+8x-24[/tex]

Using the distributive property:

[tex]x(x-3)+8(x-3)[/tex]

Then again, using the distributive property (but in reverse):

[tex](x-3)(x+8)[/tex]

The two numbers that the middle term should be split into in order to factor can be found by listing out pairs of factors for the product of the last term and the coefficient of the first term, and using the two factors whose sum is the middle term.

For eg (because that was a bit text heavy):

The product of the last term and the first coefficient (1 * (-24)) is -24

the factors of -24 include (and their sum)

-1, 24 (23)

1, -24 (-23)

-2, 12 (10)

2, -12 (-10)

-3, 8 (5)

3, -8 (-5)

-4, 6 (2)

4, -6 (-2)

The middle coefficient is 5 and the sum of the factors -3 and 8 are 5, so split 5x into -3x + 8x to be able to factor how I showed before.

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.


y = -x^2 + 99x - 932

Answers

Answer:

$49.5

Step-by-step explanation:

y = -x^2 + 99x - 932

The maximum point is :

dy/dx = 0

Take the first derivative of y

dy/dx = - 2x + 99

Put - 2x + 99 = 0

-2x = - 99

x = 99 / 2

x = 49.5

Hence, To make maximum profit, widget should be sold at $49.5 per widget.

SARAH makes $43,000 per year, is single, and lives in Connecticut. She has $19,000 in subsidized loans and $8000 in unsubsidized loans.

Answers

Answer:

The standard repayment plan.

Step-by-step explanation:

Here is the complete question :

SARAH makes $43,000 per year, is single, and lives in Connecticut. She has $19,000 in subsidized loans and $8000 in unsubsidized loans. Which repayment plan will be the cheapest for her in total?

The standard repayment plan is a repayment plan where a fixed sum is paid monthly for 10 years. This makes a total of 120 payments. The advantage of the standard repayment plan over the federal repayment plan is that less interest is paid and payment is made over a shorter period

Because unsubsidized loans accrue a higher interest expense when compared to subsidized loans, Sarah should pay off her unsubsidized loan first. This would minimise interest payment

A store sells gas and containers. One customer buys 2 containers and 8 gallons of gas for $38.06. Another customer

buys 1 container and 3 gallons of gas for $15.76.

Enter the price ,in dollars, of 1 container

Answers

Answer:

$5.95

Step-by-step explanation:

Given :

Let containers = c ;Gallon of gas = g

2c + 8g = 38.06 - - - (1)

c + 3g = 15.76 - - - - (2)

From (2) :

c = 15.76 - 3g

2(15.76 - 3g) + 8g = 38.06

31.52 - 6g + 8g = 38.06

2g = 6.54

g = 6.54 / 2

g = 3.27

Recall :

c = 15.76 - 3g

c = 15.76 - 3(3.27)

c = 5.95

0 ≤ x ≤ 2 (i assumed that the arrows included 0 and 2).

Step-by-step explanation:

One arrow shows 0 and greater (as it is pointing right) and the other shows 2 and smaller (as it is pointing left). The arrow pointing right has the equation of:

x ≥ 0 (where x is a random number)

The arrow pointing left has the equation of:

x ≤ 2 (where x is a random number)

Assuming that you need to find an equation so that x fits both inequalities, we combine them into one inequality and get:

Calebs puppy weighs 2250 grams. If the puppy weighed 600 grams at his last visit to the vet, what is the percent increase in the puppies weight

Answers

Answer:

275%

Step-by-step explanation:

Given that,

Initial weight of the puppy = 600 grams

Final weight of the puppy = 2250 gram

We need to find the percent increase in the puppy's weight.

Increase in weight = 2250 gram - 600 grams

= 1650 grams

The percentage of increase in weight,

[tex]\%=\dfrac{1650}{600}\times 100\\\\=275\%[/tex]

So, the required increase in puppy's weight is equal to 275%.
