kondor19780726 [428]

Answer:

\frac{dy}{dx} = 24 x + 21

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the function

      y = f(x) = 3 x ( 4 x + 7)

     y  = 3 x ( 4 x + 7)  

    y = 12 x² + 21 x ..(i)

Differentiating equation (i) with respective to 'x' , we get

\frac{dy}{dx} = 12 (2x) +21 (1)

\frac{dy}{dx} = 24 x + 21

A professor has 24 pairs of socks in his drawer. 18 pairs are black and the rest are brown. He always wears black pants. He does
lesya692 [45]

Answer:

The likelihood that the professor's socks matched his pants on both days is 0.5625

Step-by-step explanation:

Total no. of pair of socks = 24

No. of black pairs = 18

We are given that  he selects one pair of socks on Monday and one on Tuesday. Since he has lots of clean socks in the drawer he does not do laundry.

So, It is  a case of replacement

He always wears black pants.

We are supposed to find he likelihood that the professor's socks matched his pants on both days i.e. Black socks both days.

So ,Probability of wearing black socks on Monday = \frac{18}{24}

So ,Probability of wearing black socks on Tuesday =\frac{18}{24}

So,the likelihood that the professor's socks matched his pants on both days = \frac{18}{24} \times \frac{18}{24}=0.5625

Hence the likelihood that the professor's socks matched his pants on both days is 0.5625

Let f (x ) = 3x² - 4 and let g (x) = 2x + 1. <br> Find the value of f[g(2)].
stepan [7]

Answer:

The value of f[g(2)] is 71.

Step-by-step explanation:

We need to find f[g(2)].

The first step is finding f[g(x)]

We have that:

f(x) = 3x^{2} - 4

g(x) = 2x + 1

To find f[g(x)], the first step is replacing each x is f by g(x). So

f(g(x)) = 3(2x+1)^{2} - 4

Now we replace x by 2

f(g(2)) = 3(2*2+1)^{2} - 4 = 75 - 4 = 71

The value of f[g(2)] is 71.
