Answer:

\boxed{(f + g)(x) = {x}^{2} - x + 6}

Given:

f(x) =  {x}^{2}  + 1 \\  \\ g(x) = 5 - x

To Find:

(f + g)(x) = f(x) + g(x)

Step-by-step explanation:

=  > f(x) + g(x) =  ({x}^{2}  + 1) + (5 - x) \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = {x}^{2}  + 1 + 5 - x\\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = {x}^{2}  + 6 - x\\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: = {x}^{2} - x + 6

Given the function f(x)=x2+2x+1, find:<br> f(2b)
Maru [420]

Hey there!!

Given equation :

f ( x ) = x² + 2x + 1

Find f ( 2b )

In order to solve this question, we will need to replace the value 2b instead of x

... f(2b) = ( 2b )² + 2 ( 2b ) + 1

... f(2b)= 8b² + 4b + 1

Hope my answer helps!

15. For each of the following, write the probability as the intersection of two events. Then, indicate whether the two events ar
LuckyWell [14K]

Answer:

Step-by-step explanation:

a. The probability of selecting a 6 from the first draw and a 7 on the second draw when two balls are selected without replacement from a container with 10 balls numbered 1 to 10

Not independent because without replacement

Prob for both = \frac{1}{10} \frac{1}{9} \\=\frac{1}{90}

b. The probability of selecting a 6 on the first draw and a 7 on the second draw when two balls are selected with replacement from a container with 10 balls numbered 1 to 10

Here independent because with replacement makes probability independent.

Prob for both = P(A) *P(B) = \frac{1}{10} *\frac{1}{10} \\=\frac{1}{100}d

c. The probability that two people selected at random in a shopping mall on a very busy Saturday both have a birthday in the month of June. Assume that all 365 birthdays are equally

likely, and ignore the possibility of a February 29 leap-year birthday.

Here independent because one person birthday will not affect the other person birthday

Prob for both = (\frac{30}{365})^2\\ =\frac{25}{5329}

d. The probability that two socks selected at random from a drawer containing 10 black socks and 6 white socks will both be black

Prob for I sock black = 10/16 and II sock black if first sock is black = 9/15

Hence not independent

Prob for both = \frac{10C2}{16C2} \\=\frac{3}{8}

T is directly proportional to M.
zaharov [31]
By proportionality, for any number a, if T is multiplied by a then the same goes for M.

a) M has been multiplied by \dfrac{3}4 hence T=20\cdot\dfrac{3}4=5\cdot3=15

\boxed{T=15}

b) T has been divided by 2 hence M=\dfrac{4}2

\boxed{M=2}
