The correct answer option is C. [tex]f(x)=-2x^3-2x^2+12x[/tex].

Step-by-step explanation:

From the given graph of the polynomial function, we can see that the graph passes through the following points: [tex](-3,0), (0,0)[/tex] and [tex](2,0)[/tex].

So the roots or zeros of this polynomial function are: [tex]-3,0[/tex] and [tex]2[/tex].

Now, we'd graph the equation of the given polynomial and will check for roots and end behavior of the graph.

Therefore, the polynomial function that is represented by the graph is:

[tex]f(x)=-2x^3-2x^2+12x[/tex]

[tex]\huge{\boxed{y=\frac{1}{2} x+1}}[/tex]

First, we must find the slope of the graphed line. We can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are known points on the line.

Plug in the values. [tex]\frac{4-2}{-1-0}[/tex]

Subtract. [tex]\frac{2}{-1}[/tex]

To find the slope of the perpendicular line, we must find the opposite inverse slope. This means we first need to multiply it by [tex]-1[/tex], then we need to swap the numerator and denominator.

[tex]-2*-1=2[/tex]

Now, swap the numerator and denominator. The numerator is [tex]2[/tex], and the denominator is [tex]1[/tex] by default.

The only answer choice with a slope of [tex]\frac{1}{2}[/tex] is [tex]\boxed{y=\frac{1}{2} x+1}[/tex]

Answer:

Step-by-step explanation:

In each parallelogram opposite sides have the same length.

Therefore we have the equations:

2x - 4 = x + 12 and 3y - 2 = y + 6

2x - 4 = x + 12         add 4 to both sides

2x = x + 16         subtract x from both sides

x = 16

3y - 2 = y + 6            add 2 to both sides

3y = y + 8           subtract y from both sides

2y = 8            divide both sides by 2

y = 4

AB = 3y - 2 → AB = 3(4) - 2 = 12 - 2 = 10

Answer:

Part A: OC. 16π square inches

Part B: OC. 36π square inches

Step-by-step explanation:

Part A:

Given

Diameter of circular picture = d = 8 inches

We need to find the radius first to find the area

So,

Rdius = r = d/2 = 8/2 = 4 inches

[tex]Area = \pi r^2\\= \pi *(4)^2\\= 16\pi\ square\ inches[/tex]

Therefore, option C is the correct answer..

Part B:

As two inches frame is added around the picture, the diameter will become 8+4 =12 inches

The new radius will be:

r = 12/2 = 6

So,

[tex]Area\ with\ frame = \pi r^2\\=\pi *(6)^2\\=36\pi\ square inches[/tex]

Therefore, option C is correct ..

Answer:

x < -3

Step-by-step explanation:

using the distributive property, distribute 9(2x +1) so it's 18x + 9, subtract 9x from 18x, subtract 9 from -18, divide both sides by 9, x < -3

Inequality is a relationship between two numbers or two expressions.

The value of x in the solution set of 9(2x + 1) < 9x – 18 is

x < -3

i.e -2, -1, 0, 1, 2, 3, 4, ,,,,,,∞

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

9(2x + 1) < 9x – 18

Remove the parenthesis.

9 x (2x) + 9 x 1 < 9x - 18

18x + 9 < 9x - 18

Subtract 9x on both sides.

18x + 9 - 9x < 9x - 18 - 9x

9x + 9 < -18

Subtract 9 on both sides.

9x + 9 - 9 < -18 - 9

9x < -27

Divide both sides by 9.

9x/9 < -27/9

x < -3

This means x is less than -3.

i.e -2, -1, 0, 1, 2, 3, 4, ,,,,,,∞

Thus,

The value of x in the solution set is x < -3.

i.e -2, -1, 0, 1, 2, 3, 4, ,,,,,,∞

Answer:

the third side is √11

Step-by-step explanation:

By Pythagoras theorem, we can find the third side

c^2 = a^2 + b^2

if a = √2

b = 3

then,

c^2 = a^2 + b^2

c^2 =(√2)^2 + (3)^2

c^2 = 2+9

c^2 = 11

Taking square root on both sides:

√c^2 = √11

c = √11

So, the third side is √11

ANSWER

[tex]y = 2( {x - 4)}^{2} - 3[/tex]

EXPLANATION

The function equation of a parabola that opens up in vertex form is given by

[tex]y = a( {x - h)}^{2} + k[/tex]

where (h,k) is the vertex and 'a' is the leading coefficient.

The given graph is a parabola that opens up and has its vertex at (4,-3).

This implies that, h=4 and y=-3

We substitute these values into the vertex form to obtain,

[tex]y =a( {x - 4)}^{2} + - 3[/tex]

This simplifies to,

[tex]y =a( {x - 4)}^{2} - 3[/tex]

The graph also contains (3,-1). We plug x=3 and y=-1 into the equation to find the value of 'a'.

[tex] - 1=a( {3 - 4)}^{2} - 3[/tex]

[tex] - 1 + 3 = a( { - 1})^{2} [/tex]

[tex]2 = a[/tex]

We substitute this value to get:

[tex]y = 2( {x - 4)}^{2} - 3[/tex]

The last choice is correct.

Answer:

f (x) = (x+5) is linear

Step-by-step explanation:

We are given the following function and we are to determine if it is a linear function or not:

[tex] f ( x ) = ( x + 5 ) [/tex]

For a function to be linear, it must be written in the standard form [tex]y=mx+c[/tex] and its graph gives a straight line.

Whereas, when an equation is squared, its graph becomes a curved one which is not linear.

Therefore, the given function f (x) = (x+5) is linear.

Answer: No, it is not a linear function. It is a Quadratic function.

Step-by-step explanation:

Given the following function:

 [tex]f(x)=x(x+5)[/tex]

You need to apply Distributive property:

[tex]f(x)=(x)(x)+(x)(5)[/tex]

[tex]f(x)=x^2+5x[/tex]

You can observe that the highest exponent of the function is "2", therefore, it is not a Linear function, but a Quadratic function in the form:

[tex]f(x) = ax^2 + bx + c[/tex]

Where a, b, and c are numbers ([tex]a\neq 0[/tex])

Answer:

Graph 1: Consistent Dependent

Graph 2: Consistent Independent

Graph 3: Consistent Dependent

Graph 4: Inconsistent

Step-by-step explanation:

Consistent means they have at least one solution.  So lines that intersect once or lines that intersect infinitely many times are both consistent systems.

If they are the system that has one solution they are considered independent.

If they are the system that has infinitely many solutions then are considered dependent.

Inconsistent means they won't intersect at all.

First graph shows the same line graphed onto itself.  That means they have infinitely many solutions and is therefore a consistent dependent system.

Second graph shows the lines intersecting once.  That means they have one solution and therefore is a consistent independent system.

Third graph shows the same description of graph one and is therefore a consistent dependent system.

The last graph shows parallel lines. Parallel lines do not intersect and therefore do not have a solution.  So this system is inconsistent.

Answer:

A

Step-by-step explanation:

The graphs of two functions y=f(x) and y=g(x) intersect at one point. The coordinates of this point are (0,-2). This means

f(0)=-2

g(0)=-2

Thus,

f(0)=g(0)

Note that the blue line passes through the point (-2,4), so

f(-2)=4

and the red line passes through the point (-2,-4), so

g(-2)=-4

Hence,

f(-2)≠g(-2)

and f(0)≠g(-2)

Answer:

First Option

Step-by-step explanation:

It can be seen in the graph that the two plotted functions are linear, which means that if the lines are not parallel or not lying on each other, then the lines will intersect at most one point in the plane. It can be clearly seen that both the lines intersect at the point (0,-2). As far as the functions are concerned, there is an input and an associated output. The term f(0) means that 0 is the input and f(0) is the functional value, which is the output. In the graph, both lines have the y-intercept of -2. Y-intercept is the point where the value of the input (i.e. the value of x) is 0. Since both lines are intersecting at (0,-2), this implies that f(0) = g(0). This essentially means that the the functional value of f, which is -2, is equal to the functional value of g!!!

Final answer:

The missing term in the polynomial 36x³ - 22x + ___ that ensures a GCF of 2x must be ax, where 'a' is an even number. Possible terms could be 4x, -8x, or any other term with an even coefficient and an x factor.

Explanation:

The student's question asks which term can be used in place of the blank in the polynomial 36x³- 22x + ___ so that the greatest common factor (GCF) of the resulting polynomial is 2x. To determine the missing term, we need to look at the existing terms of the polynomial. The first term, 36x³, has a GCF of 2x because 36 is divisible by 2 and x³ has x as a factor. Similarly, the second term, -22x, also has a GCF of 2x since 22 is divisible by 2 and there's already an x present. To ensure that the GCF of the final term with the others is 2x, the term must have both a coefficient divisible by 2 and at least one factor of x.

Let's say the missing term is ax, where 'a' is an even number to keep the common factor of 2x. Therefore, a term like 4x or -8x could work. If the resulting polynomial had a term without x, then the GCF would just be 2, not 2x. Hence, adding a term with a factor of 2 and x not only completes the polynomial but also ensures that the GCF is 2x.

Answer:

65 units²

Step-by-step explanation:

The polygon is composed of a trapezium and a triangle

Trapezium QRSU has area (A)

A = 0.5 h (a + b)

where h is the perpendicular height and a, b are the parallel bases.

h = RS = 7 , a = RQ = 6 and b = SU = 8, so

A = 0.5 × 7 × (6 + 8) = 0.5 × 7 × 14 = 49 units²

Triangle STU has area ( A )

A = 0.5 bh ( b is the base and h the perpendicular height )

here b = SU = 8 and h = 4 ( distance from vertex T to the base SU), so

A = 0.5 × 8 × 4 = 16 units²

Total area = 49 + 16 = 65 units²

Answer:

D. Y+5=-(1/2)*(x+3)

Step-by-step explanation:

Perpendicular Lines are those with the following condition:

y=a*x+b (1)

y=c*x+d (2)

Where 'a' and 'c' are the respective slope

If These two lines are perpendicular, then

a=- 1/c

Equation (1) for our case is written as y=2x-8, meaning that a=2 and b = -8

Using those principles we have that the slope for our needed line ('c') has to be -(1/2).

Now we most use the given point to find the remaining term of the equation (d) so, evaluate (-3,-5) in eq (2) to have this:

-5=(-1/2)*(-3)+d

resulting that d=-5-(3/2)

Eq (2) is written now as the following: y= (-1/2)*x - (5+3/2)

Rearranging terms, we have the following:

y+5=(-1/2)*x-(3/2)

where you can obtain a more pretty expression:

y+5=(-1/2)*(x+3)

Step-by-step explanation:

Given that line a is parallel to line b

∠6 = ∠2 = 36.5° (property of corresponding angles)

∠8 = 180° -∠6 (property of adjacent angles on a straight line)

∠8 = 180° - 36.5° = 143.5°

Answer:

y = 5x - 39

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5, hence

y = 5x + c ← is the partial equation

To find c substitute (8, 1) into the partial equation

1 = 40 + c ⇒ c = 1 - 40 = - 39

y = 5x - 39 ← equation of line

To write the equation of a line, we will use the slope-intercept form of the equation of a line, which is given by:
\[ y = mx + b \]
where \( m \) is the slope and \( b \) is the y-intercept of the line.
Given the point (8, 1) through which the line passes, and the slope \( m = 5 \), we will plug these values into the equation to find \( b \).
The coordinates of the point give us values for \( x \) and \( y \); specifically, \( x = 8 \) and \( y = 1 \). Using these, we can substitute into the slope-intercept formula:
\[ 1 = 5(8) + b \]
This simplifies to:
\[ 1 = 40 + b \]
To find \( b \), we'll isolate it on one side:
\[ b = 1 - 40 \]
\[ b = -39 \]
Now that we have \( b \), we can write the equation of the line with the given slope \( m \) and y-intercept \( b \):
\[ y = 5x - 39 \]
So the equation of the line that passes through the point (8, 1) with a slope of 5 is:
\[ y = 5x - 39 \]
