What is the factored form of the polynomial?
x2 − 12x + 27?

Answers

Answer 1
Answer:

Answer:

(x-9)(x-3) which is the same as (x-3)(x-9)

Step-by-step explanation:

Think of ways to factor the last number 27. One way is 1*27 = 27. Another way is 3*9 = 27 and so on. Now think to yourself "which factor of 27 add to -12?". You'll need to consider negative factors. It turns out that

-3 plus -9 = -12

-3 times -9 = 27

Therefore the two values we care about are -9 and -3. So x^2-12+27 factors to (x-3)(x-9). The order of the factors does not matter. So we can write the answer as (x-9)(x-3) just fine.

A hovercraft takes off from a platform. It’s height (in meters), x seconds is modeled by h(x)=-(x-11)(x+3). What is the height of the hovercraft at the time of the takeoff?

Answers

Answer:

The height of the hovercraft at the time of takeoff is  33  meters.

Step-by-step explanation:

Height of hovercraft  x  seconds after takeoff  =  h(x)  =  -(x - 11)(x + 3)

Height after takeoff is  =  h(0)  =  -(0 - 11)(0 + 3)  =  -(-11)(3)  =  33

So the correct answer is 33 meters. The height of the hover craft at the time of the takeoff is 33 metres.

Answer: 33  meters.

~Please only answer if you know for sure~You bought a car for $20,000. You have owned it for one year, and it is now worth $16,000. What is the percent decrease in your car's value?

20%


25%


80%


125%

Answers

Answer:

Option A. 20%

Step-by-step explanation:

Since the cost price of the car when it was new = $20000

After one year car value $16000.

We have to calculate the depreciation in the price or my car.

So decease in the car's value = 20000-16000 = $4000

Since cost price of the car was = $20000

therefore % decrease decrease in the price will be = (decrease in price/cost price)×100 = (4000/20000)×100 = 20%
20%.

20,000 times 0.8 is 16,000, so the decreased value that was lost was 20% of the original price.
