1) Suppose f(x) = x2 and g(x) = |x|. Then the composites (fog)(x) = |x|2 = x2 and (gof)(x) = |x2| = x2 are both differentiable a

Rufina [12.5K]

Answer:

This contradict of the chain rule.

Step-by-step explanation:

The given functions are

$f(x)=x^2$

$g(x)=|x|$

It is given that,

$(f\circ g)(x)=|x|^2=x^2$

$(g\circ f)(x)=|x^2|=x^2$

According to chin rule,

$(f\circ g)(c)=f(g(c))=f'(g(c)g'(c)$

It means, $(f\circ g)(c)$ is differentiable if f(g(c)) and g(c) is differentiable at x=c.

Here g(x) is not differentiable at x=0 but both compositions are differentiable, which is a contradiction of the chain rule

Which improper fraction is represented by the model?<br> 12 / 4<br> 10 / 3<br> 12 / 3

Ksivusya [100]

Answer:

$\frac{10}{3}$

Step-by-step explanation:

each circle is composed of 3 sectors

The first 3 are completely shaded representing 3 + 3 + 3 = 9 sectors

the last one has 1 sector of 3 shaded representing 1 sector

sectors shaded = 9 + 1 = 10

improper fraction is then $\frac{10}{3}$

Which of the following correctly uses exponents to write "6 factors of 2"? A.62 B.26 C.6 ∙ 2 D.12

kotegsom [21]

Step-by-step explanation:

1. 6 factors of 2 means, 2 multiplied by itself 6 times. It can be written in the form of exponents as 2⁶.

2. $2^m{\cdot} 2^n$

The law of exponent is : $x^a{\cdot} x^b=x^{a+b}$

So,

$2^m{\cdot} 2^n=2^{m+n}$

The correct option is (A).

3. If the power of any number is 0, then the value of that number is equal to 1.

So,

$23^0=1$

Hence, this is the required solution.

I don’t know hellppppp

marusya05 [52]

Answer:

part a in 3 months there are 108 rabbits

for 4 months put 328 rabbits

part b. for 1 month put 12 rabbits

for 3 months put 48 rabbits

Step-by-step explanation:

part a: so the pattern is multiply by 3 , the rabbits triple every month. so

4 times 3 = 12 which is the number of rabbits in 1 month so to find the third month multiply 12 by 3 which equals 36

then 36 by 3= 108 and so on.

part b: the pattern is multiply by 2. so the rabbits double each month. 6 times 2= 12 so 12 rabbits for 1 month the 12 times 2 = 24 rabbits for month 2 then 24 time 2= 48 rabbits for 3 months.
