The value of the required function is [tex](3x^{3} + 6x^{2} - x - 2)[/tex].

A function represents the relation between two sets. The first one is called domain and the second one is called range.

Two given functions are:

[tex]f(x) = x + 2 \\g(x) = 3x^{2} - 1[/tex]

Therefore the required function,

[tex](fg)(x)= f(x)g(x) \\= (3x^{2} - 1)(x + 2)\\= 3x^{3} - x + 6x^{2} - 2\\ = 3x^{3} + 6x^{2} - x - 2[/tex]

Answer:

[tex]6[/tex].

Step-by-step explanation:

A line that goes through [tex](x_{0},\, y_{0})[/tex] and [tex](x_{1},\, y_{1})[/tex] where [tex]x_{0} \ne x_{1}[/tex] would have a slope of [tex]m = (x_{1} - x_{0}) / (y_{1} - y_{0})[/tex].

The slope of the line that goes through [tex](8,\, 4)[/tex] and [tex](-1,\, 1)[/tex] would thus be:

[tex]\begin{aligned}m_{2} &= \frac{1 - 4}{(-1) - 8} \\ &= \frac{(-3)}{(-9)} \\ &= \frac{1}{3}\end{aligned}[/tex].

Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is [tex](-1)[/tex].

Thus, if [tex]m_{1}[/tex] and [tex]m_{2}[/tex] denote the slope of the first and second lines in this question, [tex]m_{1}\, m_{2} = (-1)[/tex] since the two lines are perpendicular to one another. Since [tex]m_{2} = (1/3)[/tex], the slope of the first line would be:

[tex]\begin{aligned} m_{1} &= \frac{(-1)}{m_{2}} \\ &= \frac{(-1)}{(1/3)} \\ &= (-3)\end{aligned}[/tex].

Given that the first line goes through the point [tex](1,\, 0)[/tex], the point-slope equation of that line would be:

[tex](y - 0) = (-3)\, (x - 1)[/tex].

[tex]y = -3\, x + 3[/tex].

Substitute in [tex]x = (-1)[/tex] to find the [tex]y[/tex]-coordinate of the point in question:

[tex]y = -3\times (-1) + 3 = 6[/tex].

Answer:

Step-by-step explanation:

there are 2 corners that are blue out of 4

2/4 is the same as 1/2

Answer:

It is a right angled triangle.

so

tan32 = p/b

or, tan32 = x/5

or, tan32×5 = x

so, x = 3.124

for 5 no. the answer is a. 3.124

For y,

cos32 = b/h

or, cos32 = 5/y

or, y = 5/cos32

so, y = 5.895

for 6 no. 5.895 is closest to 5.994, so the answer is c. 5.994.

The rate of return for the $12,000 investment in one year is 12%.

The correct answer is option C) 12 percent.

The simple interest formula can be expressed as:

Interest = Principal × Rate × Time

Given the parameters:

Principal P = $12,000

Interest I = $1,440

Elapsed time t = 1 year

Interest rate r =?

Plug the given values into the formula above and solve for the interest rate.

Interest = Principal × Rate × Time

1440 = 12000 × Rate × 1

1440 = 12000 × Rate

Rate = 1440 / 12000

Rate = 0.12

Convert to percentage:

Rate = 0.12 × 100%

Rate = 12%

Therefore, the interest rate is 12 percent.

Option C) 12 percent is the correct answer.

Answer:

The spy plane will re-fuel at coordinates ( 8, 7 )

Step-by-step explanation:

The spy plane leaves a secret runway at A (–16 , 28) and heads toward a missile factory at B.

We have to find Line 1

Runway (-16,28)

-16 = x2

28 = y2

Missile Factory

(48, –28)

48 = x1

-28 = y1

So we set up the equation:

a = y2 - y1 / x2 - x1 = 28 - (-28) / -16 - 48 = 56/-64 = -0.875

Now we must find the equaion: y = ax + b

we substitute a with -0.875

so the new equation will look like this: y = -0.875x + b

y2 = 28 = y

x2 = -16 = x

y = -0.875x + b

28 = -0.875(-16) + b

28 = 14 + b

28 - 14 = 14 - 14 + b

14 = b

so y = -0.875x + 14

Now lets solve for Line 2

we use the same formula:

a = y2 - y1 / x2 - x1 = 37 - (-13) / 56 - (-24) = 50/80 = 0.625

Now we must find the equaion: y = ax + b

we substitute a with 0.625

so the new equation will look like this: y = 0.625x + b

y2 = 37 = y

x2 = 56 = x

y = 0.625x + b

37 = 0.625(56) + b

37 = 35 + b

37 - 35 = 35 - 35 + b

2 = b

so y = 0.625x + 2

Now according to the text, it says "At what coordinates will the two planes meet to re-fuel the spy plane"

which means we have to find the point of intersection, which means we have to make both equation = to each other

so the problem would look like this:

-0.875x + 14 = 0.625x + 2

-0.875 + 0.875x + 14 = 0.625x + 0.875x + 2

14 = 1.5x + 2

14 - 2 = 1.5x + 2 - 2

12 = 1.5x

12/1.5 = 1.5x/1.5

8 = x

now that we know the x, we need to find the y

so y = 0.625x + 2 turns into

y = 0.625(8) + 2

y = 5 + 2

y = 7

so the answer is: The spy plane will re-fuel at coordinates ( 8, 7 )

Answer:

Step-by-step explanation:

We know that:

We know that if two lines are parallel, then their slopes must be the same. However, their y-intercepts are different. Using the graph I made, we can identify the original line. Looking at the graph, we can conclude that the y-intercept is 7.

Hence, the equation of the line is y = 2x + 7.
