Find the derivation of y=sin (2x2 + 3x-4)<br />a. -cos (4x +3) b. -(6x2+3) cos (2x3+3x-4) c. Cos (2x3+3x-4)<br />d. (6x3+3) cos (2x3+3)<br />​

Answers

Answer 1
Answer:

Let y = f(x)

f(x) = sin x

g(x) = (2x^2 + 3x - 4)

Use the chain rule.

We want y' = f' (g(x)) • g'(x).

y' = cos(2x^2 + 3x - 4) • (4x + 3)

Done.

Absolute value -1+5 |n|=44 pls show work

Answers

Answer:

n = -9 or 9

Step-by-step explanation:

-1 + 5|n| = 44

~Add 1 to both sides

5|n| = 45

~Divide 5 to both sides

|n| = 9

~Knowing the absolute value rule, the answer can be positive or negative.

Best of Luck!

Answer:

  • The value of n is 9 or -9.

Step-by-step explanation:

  • -1 + 5|n| = 44
  • => 5|n| = 44 + 1
  • => 5|n| = 45
  • => |n| = 45/5
  • => |n| = 9 or -9
  • => n = 9 or -9

Hence, the value of n is 9 or -9.

Dilution ProblemSamantha needs 115 liters of a solution that has a concentration of 14 g/ml for the manufacture of computer parts.
Samantha has an unlimited supply of a solution with a concentration of 21 g/ml.
Using the Formula C1×V1 = C2×V2 to answer the following questions
Round answers to the nearest 10th.

How many liters of 21 g/ml does Samantha need to equals the amount of soluble in the given solution?
(Concentration times Volume = grams of soluble, like salt)​

Answers

Answer:

  76.7 liters

Step-by-step explanation:

You have ...

  C1×V1 = C2×V2

so ...

  V2 = V1×(C1/C2) = (115 L)×(14/21) = 76 2/3 L

  V2 ≈ 76.7 L

At a computer store, a customer is considering 9 different computers,10 different monitors,8 different printers and 2different scanners. Assuming that each of the components is compatible with one another and that one of each is to be selected. Determine the number of different computer systems possible.

Answers

Answer:

The number of different computer systems possible is 1440.

Step-by-step explanation:

For each computer, there are 10 options of monitor.

For each monitor, there are 8 printers.

For each printer, there are 2 scanners.

There are 9 computers.

Determine the number of different computer systems possible.

9*10*8*2 = 1440

The number of different computer systems possible is 1440.

Step-by-step explanation:

A given binomial distribution has 10 trials and probability of success p=1/3. Compute the standard deviation and explain your solution

Answers

Answer: 1.49

Step-by-step explanation:

We know that the standard deviation in a binomial distribution is given by :-

\sigma=√(n\cdot p\cdot (1-p)), where n is the number of trials and p is the probability of success.

Given : The number of trials : n=10

The probability of success = p=(1)/(3)

Then , the standard deviation will be :-

\sigma=\sqrt{10\cdot (1)/(3)\cdot (1-(1)/(3))}\n\n\Rightarrow\ \sigma=1.490711985\approx1.49
