Given f(x) = x^2-6x - 16 Determine when f(x) = 0

Mathematics
1 answer:
Komok [63]3 years ago

Answer:

x = -8 or 8

Step-by-step explanation:

So, we need to know when x^2  - 6x - 16 = 0.

Let's solve this! :)

We can add 16 to both sides:

x^2 - 6x = 16

Now, we can simply tell that x^2 has to be 16 more than -6x, so the answer must be smaller than -6 or greater than 6.

By making an educated guess, we get x = -8 or x = 8 :)

Use​ Gauss's approach to find the following sums​ (do not use​ formulas). 1+3+5+7+...999
muminat
S=1+3+5+\cdots+995+997+999
S=999+997+995+\cdots+5+3+1
\implies 2S=(1+999)+(3+997)+(5+995)+\cdots+(995+5)+(997+3)+(999+1)

2S=\underbrace{1000+1000+\cdots+1000+1000}_{500\text{ times}}

(We are adding 500 instances of 1000 because that's how many odd numbers there are between 1 and 1000, inclusive.)

2S=500\times1000=500000
\implies S=250000

Write a summary about decimals that are equivalent to fractions with denominators of 10 or 100. EXTRA CREDIT
Flura [38]
Decimals that contain a zero in the tenth position can be thought of as a fraction over 100 as the tenth isn't occupied and the hundredth correlates to the 100 as a denominator. The same goes for a number with the tenth position occupied. These decimals would be put over 10 as they are occupying that position in the decimal.
