Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

There are 2 possible approaches to differentiating these.

Expand the factors and differentiate term by term, or

Use the product rule for differentiation.

I feel they are looking for use of product rule.

Given

y = f(x). g(x) , then

[tex]\frac{dy}{dx}[/tex] = f(x).g'(x) + g(x).f'(x) ← product rule

(a)

y = (2x - 1)(x + 4)²

f(x) = 2x - 1 ⇒ f'(x) = 2

g(x) = (x + 4)²

g'(x) = 2(x + 4) × [tex]\frac{d}{dx}[/tex] (x + 4) ← chain rule

       = 2(x + 4) × 1

        = 2(x + 4)

Then

[tex]\frac{dy}{dx}[/tex] = (2x - 1). 2(x + 4) + (x + 4)². 2

    = 2(2x - 1)(x + 4) + 2(x + 4)² ← factor out 2(x + 4) from each term

    = 2(x + 4) (2x - 1 + x + 4)

    = 2(x + 4)(3x + 3) ← factor out 3

    = 6(x + 4)(x + 1)

--------------------------------------------------------------------------

(b)

y =  x(x² - 1)³

f(x) = x ⇒ f'(x) = 1

g(x) = (x² - 1)³

g'(x) = 3(x² - 1)² × [tex]\frac{d}{dx}[/tex] (x² - 1) ← chain rule

        = 3(x² - 1)² × 2x

        = 6x(x² - 1)²

Then

[tex]\frac{dy}{dx}[/tex] = x. 6x(x² - 1)² + (x² - 1)³. 1

    = 6x²(x² - 1)² + (x² - 1)³ ← factor out (x² - 1)²

    = (x² - 1)² (6x² + x² - 1)

     = (x² - 1)²(7x² - 1)

----------------------------------------------------------------------

(c)

y = (x² - 1)(x³ + 1)

f(x) = x² - 1 ⇒ f'(x) = 2x

g(x) = (x³ + 1) ⇒ g'(x) = 3x²

Then

[tex]\frac{dy}{dx}[/tex] = (x² - 1). 3x² + (x³ + 1), 2x

   = 3x²(x² - 1) + 2x(x³ + 1) ← factor out x

   = x[3x(x² - 1) + 2(x³ + 1) ]

   = x(3x³ - 3x + 2x³ + 2)

   = x(5x³ - 3x + 2) ← distribute

    = 5[tex]x^{4}[/tex] - 3x² + 2x

--------------------------------------------------------------------

(d)

y = 3x³(x² + 4)²

f(x) = 3x³ ⇒ f'(x) = 9x²

g(x) = (x² + 4)²

g'(x) = 2(x² + 4) × [tex]\frac{d}{dx}[/tex](x² + 4) ← chain rule

       = 2(x² + 4) × 2x

       = 4x(x² + 4)

Then

[tex]\frac{dy}{dx}[/tex] = 3x³. 4x(x² + 4) + (x² + 4)². 9x²

    = 12[tex]x^{4}[/tex](x² + 4) + 9x²(x² + 4)² ← factor out 3x²(x² + 4)

    = 3x²(x² + 4) [ 4x² + 3(x² + 4) ]

    = 3x²(x² + 4)(4x² + 3x² + 12)

    = 3x²(x² + 4)(7x² + 12)

Answer: x= -8 and y = -20

Answer:

D - No, the ordered pair (4,9) is a solution to this problem.

Step-by-step explanation:

If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)

In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;

(2, 4.5)

(3, 6.75)

(4, 9)

So that is why the ordered pair of (4,9) would be a solution to this problem.

Hope that makes sense!

Step-by-step explanation:

I'm pretty sure that I'm correct. Hope this helps and have a nice day!

Answer:

they have to win 15 games more to have a .500 record

Step-by-step explanation:

If .500 means half,then :

half of 50 games= 25 games

They already won 10

So they need to win 15 more games to have 25 games (half of the 50 games)

Answer: A (12x−5)(2x−1)

Step-by-step explanation:

The expression which is equivalent to the given would be; C (12x - 5)(2x - 1).

Those expressions that might look different but their; simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple.

We have been given an expression as;

24x² - 22x + 5

Factor out;

24x² - (12 + 10)x + 5

(12x−5)(2x−1)

Therefore, the expression which is equivalent to the given would be; C (12x - 5)(2x - 1).

Step-by-step explanation:

The statements that is needed in order to prove these triangles are congruent using SSS is; AB ≅ DE

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

ASA or Angle-Side-Angle stated that If two corresponding interior angles of two triangles and the included sides are congruent, the triangles are congruent.

SSS or Side-Side-Side postulate state that If three corresponding sides of two triangles are congruent, the triangles are congruent.

In a triangle BCA≅ EFD

three corresponding sides must be equal.

Answer: A

Step-by-step explanation:

Answer:

Assuming that for every baby the probability of being a girl or a boy is the same (50% for each of them)

We could then think in this situation as a coin flip.

Suppose that you flip a coin 4 times, and the four times you get heads.

Does this imply that in the 5th flip the probability of getting tails increments?

Well, not, each flip is an individual event, and it's outcome does not depend on the outcome of the previous flips.

The same is for the new baby, the gender does not depend on the gender of the previous babies, is an independent event, then Susan's statement is false.

Answer:

2.5

Step-by-step explanation:

plug in 0 where x is in the equation to find y

y = -3x + 2.5

y = -3(0) + 2.5

y = 2.5

check it by subbing 2.5 into the y values

2.5 = -3x + 2.5

-2.5. -2.5

0 = -3x

+3x

3x = 0

x = 0

Answer:

6x+5=5x+8+2x

x= -3

Step-by-step explanation:

use like terms so add 5x+2x=7x

6x+5=7x+8

subtract 5 from both sides

6x+5-5=7x+8-5

simplify

-x = 3

divide both sides by -1

-x/-1  =  3/-1

x= -3

so no -5 is not a solution

Answer:

Step-by-step explanation:

Answer:

4600

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4

This indicates the sequence is arithmetic with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = - 6 and d = 4 , then

[tex]S_{50}[/tex] = [tex]\frac{50}{2}[/tex] [ (2 × - 6) + (49 × 4) ]

     = 25(- 12 + 196)

     = 25 × 184

     = 4600

The sum of the first 50 terms of the sequence -6,-2,2,6,...., is 4600.

A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

We have the sequence:

-6,-2,2,6,....

In order to solve the problem:

First, we find the common difference.

-2 + 6 = 4,

2 + 2 = 4,

6 - 2= 4.

d = 4 is the common difference.

That means, the sequence is an arithmetic sequence.

The sum of n terms,

=  [2a₁ + (n - 1)d],

where a₁ is the first term and d is the common difference.

Here, a₁ = - 6, n = 50 and d = 4,

Then

[2a₁ + (n - 1)d] =  [(2 × -6) + (49 × 4)]

                     = 25(- 12 + 196)

                     = 25 × 184

                     = 4600.

Therefore, the sum of the first 50 term is 4600.
