So, the function can be written as :

Answer:

rewrite f(g(-2))

plug in -2 in g(x)

g(x)=-2-3

g(x)=-5

now plug in -5 into f(x)

Answer:

-2x^3+6x^2

or simplified : -2x^2(x-3)

Step-by-step explanation:

Rewrite the statement as:

[tex]((x^2)(x-3))(-2)\\[/tex]

Distribute:

[tex](x^2*x-3*x^2)(-2)\\(-2)(x^3-3x^2)\\-2x^3+6x^2[/tex]

simplify by taking a common factor out, in this case, -2x^2:

Answer:

  $545

Step-by-step explanation:

Finding the price that maximizes profit requires several steps. We need the demand function that tells quantity sold in terms of selling price. With this, we can express the cost and revenue functions in terms of selling price. The profit will be the difference between revenue and cost.

__

The demand (q) is said to be a linear function of price (p). The equation for that can be written ...

  q(p) = (q2 -q1)/(p2 -p1)(p -p1) +q1 . . . . . for two points (p1, q1) and (p2, q2)

Using the given demand points, this can be ...

  q(p) = (1900 -2600)/(575 -470)(p -470) +2600

  q(p) = -20/3(p -470) +2600

  q(p) = -20/3p +5733 1/3

__

The cost function in terms of selling price can be found by substituting the q(p) equation for x in c(x). For the purpose of finding the maximum profit, we only need the marginal cost function:

  c(q(p))' = c'(q(p))·q'(p) = (608 -0.18(q(p)))·(-20/3) = (608 -0.18(-20/3p +5733 1/3))(-20/3)

  c'(p) = -8p +2826 2/3

__

As with cost, the function we need for finding the maximum profit is the marginal revenue function. Revenue is the product of price and demand, so the marginal revenue is ...

  r(p) = p·q(p)

  r'(p) = q(p) +p·q'(p) = (-20/3p +5733 1/3) +p(-20/3)

  r'(p) = -40/3p +5733 1/3

__

The maximum profit is found where the marginal profit is zero. In turn, that is found where the difference between marginal revenue and marginal cost is zero:

  P = R -C

  P'(p) = 0 = r'(p) -c'(p) = (-40/3p +5733 1/3) -(-8p +2826 2/3)

  0 = -16/3p +2906 2/3

  16p = 8720 . . . . . multiply by 3, add 16p

  p = 545 . . . . . . . price for maximum profit

The price per set that maximizes profit is $545.00.

Natalie Albert deposited checks totaling $1,735,97 into her savings account, she withdrew $100.00 while depositing some coins. If her total deposit was $1,668.71 then Natalie deposited $32.74 in coins.

Two or more expressions with an Equal sign is called as Equation.

Let's call the amount Natalie deposited in coins "x".

We know that her total deposit was $1,668.71,

so we can write an equation:

1,735.97 - 100.00 + x = 1,668.71

Simplifying, we get:

1,635.97 + x = 1,668.71

Subtracting 1,635.97 from both sides, we get:

x = 32.74

Therefore, Natalie deposited $32.74 in coins.

Answer:

x ≤ 2

Step-by-step explanation:

4.5 = medium ice cream

0.75x = toppings, x = amount of toppings

Sophia has $6.4, so 4.5+0.75x has to be less or equal to that.

4.5 + 0.75x ≤ 6.4, solve

0.75x ≤ 1.9

x ≤ 2 8/15

BUT you cannot get half a topping or a fraction of a topping,

so, x ≤ 2 toppings.

Sophia can get 2 or less toppings.

The volume formula is length x width x height. 7x5x12=420 cubic inches

Step-by-step explanation:

The area of the rectangle in terms of x is 2x² - 8

A rectangle is a quadrilateral with four right angles in the Euclidean plane.

Given one side of the rectangle is 2x+4 and the perimeter is 6x+4

Let the other side be y.

We know that:

perimeter = 2 × (sum of two sides)

or, 6x + 4 =  2 (2x+4+y)

or,6x + 4 = 4x + 8 + 2y

or, 2x - 4 = 2 y

or, y = x - 2

Now area of the rectangle = product of sides =  (x - 2)(2x+4)

Area = 2x² - 4x + 4x - 8

or, Area = 2x² - 8

Hence the area of the rectangle in terms of x is  2x² - 8

Answer:

Step-by-step explanation:

a. 15/3=5 plus 10 is 15

The percentage of households that were not watching the show were 46.81%.

In this case, we need to find the percentage of households that don´t watch the show. First, we need to know how much households don´t watch the show, this is:

[tex]94,000,000-50,000,000=44,000,000[/tex]

So, the households that were not watching the show were 44 million.

Now we can calculate the percentage, to find a percentage we use a division and to introduce the percentage units we multiply by 100.

The percentage of households that were not watching the show were 46.81%.

to the right is P(z> Z)

so P(z>Z) = 0.9909

P(z< Z) = 1- 0.9909 = 0.0091

Closest values from a z-table

P(z< -2.37) = 0.00889 (-0.00011 away)

p(z< -2.36) = 0.00914 (+0.00014 away)

so the answer must be (c) since it is between -2.36 and -2.37

Finding a₁₂

Answer:

[tex]a_{12}=106[/tex]

Step-by-step explanation:

Arithmetic sequence

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

where:

Given:

To find the common difference (d), substitute the given values into the general formula and solve:

[tex]\begin{aligned}\implies a_6=(-4)+(6-1)d & =46\\ 5d-4 & =46\\ 5d & = 50\\ d & =10\end{aligned}[/tex]

Therefore, the equation for the nth term is:

[tex]\begin{aligned}a_n &=-4+(n-1)10\\& =10n-14 \end{aligned}[/tex]

To find the 12th term, substitute n = 12 into the equation:

[tex]\implies a_{12}=10(12)-14=106[/tex]
