<h3>Speed of light:</h3>

3.05 \times 10 ^{8} m/s

<h3 /><h3>Seconds in a year:</h3>

3.15 \times 10 ^{7}

\rule{300pt}{3pt}

Multiply the speed of light with seconds in a year

*Note:- We will not change the values because speed of light is in m/s and the time is also given in seconds.

\rule{300pt}{3pt}

3.08 \times 10 ^{8}  \times 3.15 \times 10 ^{7}

(3.05 \times 3.15) \times (10 ^{8}  \times 10 ^{7} )

9.4675 \times 10 ^{15}

\tt9.46 \: Trillion \: Kilometers

I need help plz, i will give brainliest for the correct answer
DanielleElmas [232]

Answer:

  • f'(1) exists: f'(1) = -2
  • f'(0) DNE

Step-by-step explanation:

<h3>a)</h3>

The function is continuous for x > 0 . The derivative is defined on that interval and is equal to ...

  f'(x) = -2x . . . . . for x > 0

Then at x = 1, the derivative is ...

  f'(1) = -2(1)

  f'(1) = -2

__

<h3>b)</h3>

The function has a jump discontinuity at x=0, so the derivative does not exist at that point. A condition for the existence of the derivative is that the function is continuous at the point of interest.

What are the solutionso of 8x^2 = 6 + 22x
liraira [26]
You can get all the terms on one side, and then solve for x by any means:
0 = -8x^2+22x+6

Factor out a -2:
0 = -2(4x^2-11x-3)

Factor this equation:
0 = 4x^2-11x-3

I will use the AC method. To use it, first multiply a and c (in ax^2 + bx +c):
4*-3 = -12

Now, look for two numbers that multiply to -12 and add to -11. Obviously these numbers are -12 and 1. (-12*1 = -12 and -12+1  = -11). Now, because of rules, you set it up in a Punnett square:

4x^2        -12x
x              -3

Now, we find common factors of the terms in rows:
     _x_______-3__
4x| 4x^2        -12x
1   | x              -3

So, you can use this to write an equivalent expression to the quadratic given:
(x-3)(4x+1)

Now, we known the factors are (solve for x): 3 and -1/4.
