Answer:

see below

Step-by-step explanation:

The function is only defined for x < 1, and is undefined for x=1 or more. Thus the graph stops at x=1, with an open circle indicating the function is not defined there.

Answer:

The required graph is shown in figure 1.

Step-by-step explanation:

Consider the provided function f(x)=x if x<1

Here the sign of inequality is x<1.

That means the value of x can be anything less then 1.

Note the sign "<" indicates that the value x is strictly less than 1 also it is not equal to 1.

For x=1 the function is not defined.

For the inequity "<" and ">" we use an open dot or open circle which shows that the value is not included.

Now draw the table and substitute some value of x as shown.

Substitute x=0 in the provided equation.

f(x)=0

For x=0 the value of f(x) is also 0.

Substitute x=-1

f(x)=-1

For x=-1 the value of f(x) is also -1.

Substitute x=-2

f(x)=-2

For x=-2 the value of f(x) is also -2.

The required table is shown below:

x   0  -1  -2

f(x) 0  -1  -2

Now plot the above points and join them.

The required graph is shown in figure 1.

Answer:

BC = 144 units

Step-by-step explanation:

It is given a line segment BC.

D is the point on the line segment.

To find the length of BC

BC = 8x

CD = 3x + 8  and BD = 4x + 10

BC = CD + BD

8x = 3x + 8 + 4x + 10

8x = 7x + 18

x = 18

BC = 8x = 8 * 18 = 144 units

Therefore the length of segment BC = 144 units

Segment BC is 144 units

Check the picture below.

let's notice that the angle at K is an inscribed angle with an intercepted arc

[tex]\bf \stackrel{\textit{using the inscribed angle theorem}}{K=\cfrac{\widehat{LI}+\widehat{IJ}}{2}}\implies 9x+1=\cfrac{(10x-1)+59}{2} \\\\\\ 9x+1=\cfrac{10x+58}{2}\implies 18x+2=10x+58\implies 8x+2=58 \\\\\\ 8x=56\implies x=\cfrac{56}{8}\implies x=7 \\\\[-0.35em] ~\dotfill\\\\ K=9x+1\implies K=9(7)+1\implies \boxed{K=64}[/tex]

now, let's notice something again, the angle at L is also an inscribed angle, intercepting and arc of 97 + 59 = 156, so then, by the inscribed angle theorem,

∡L is half that, or 78°.

now, let's take a look at the picture down below, to the inscribed quadrilateral conjecture, since ∡J and ∡I are both supplementary angles, then

∡I = 180 - 64 = 116°.

∡J = 180 - 78 = 102°.

The measure of all the angle of KLIJ which is inscribed in circle k(O) are, 64, 78, 116, 102 degrees.

Inscribed angle theorem is the theorem, which state that the angle inscribed in a circle will be half of the angle which delimits the same arc on the circle.

The quadrilateral KLIJ is inscribed in circle k(O). In this the measure of the angle are given as,

[tex]m\angle K = (9x+1)^o[/tex]

m (arc) LI = (10x−1)°

m (arc) IJ = 59°,

m (arc) KJ =97°

All angles of the quadrilateral KLIJ has to be found out. By the inscribed angle theorem,

[tex]K=\dfrac{LI+IJ}{2}\\9x+1=\dfrac {10x-1+59}{2}\\18x+2=10x+58\\8x=56\\x=7[/tex]

Therefore, the value of the angle k is,

[tex]m\angle K = (9(7)+1)^o\\m\angle K = 64^o[/tex]

Similarly, the measure of the angle L is,

[tex]m\angle L=\dfrac{KJ+IJ}{2}\\m\angle L=\dfrac {97+59}{2}\\m\angle L=\dfrac{156}{2}\\m\angle L=78^o[/tex]

Now the angles I and J are the supplementary angles of the angle K and angle L respectively. Therefore,

[tex]m\angle I=180-m\angle K=180-64=116^o\\ m\angle J=180-m\angle L=180-78=102^o[/tex]

Hence, the measure of all the angle of KLIJ which is inscribed in circle k(O) are, 64, 78, 116, 102 degrees.

Answer:

x < - 1

Step-by-step explanation:

Given

5x + 8 < 3(x + 2) ← distribute

5x + 8 < 3x + 6 ( subtract 3x from both sides )

2x + 8 < 6 ( subtract 8 from both sides )

2x < - 2 ( divide both sides by 2 )

x < - 1

The inequality 5x + 8 < 3(x + 2) simplifies to x < -1.

To solve the inequality 5x + 8 < 3(x + 2), we must simplify and isolate the variable x. We start by distributing the 3 on the right side:

5x + 8 < 3x + 6

Next, we'll subtract 3x from both sides to get:

2x + 8 < 6

Now subtract 8 from both sides to isolate the term with x:

2x < -2

Finally, we divide both sides by 2:

x < -1

The solution to the inequality is all x-values that are less than -1.

Answer:

the function g(X) is a translation of [tex]f(x) = \sqrt{x}[/tex]

the range is {y|y≥-1}

the function g(x) can be translated 3 units right and 1 unit up to get the function [tex]f(x) = \sqrt{x}[/tex]

Step-by-step explanation:

Given the graph of a function g(x)

g(x) looks like a square root function

So parent function is [tex]f(x) = \sqrt{x}[/tex]

the function g(X) is a translation of [tex]f(x) = \sqrt{x}[/tex]

the domain is {x| x ≥ -3}

the range is {y|y≥-1}

The parent function [tex]f(x) = \sqrt{x}[/tex] starts at (0,0)

so g(x) is translated 3 units left and 1 unit down

the function g(x) can be translated 3 units right and 1 unit up to get the function [tex]f(x) = \sqrt{x}[/tex]

Answer:

The correct options are 1, 3 and 5.

Step-by-step explanation:

The given function is a continuous increasing curve which is increasing at decreasing rate. It means it is the graph of a radical function.

Parent radical function is

[tex]f(x)=\sqrt{x}[/tex]

It means function g(x) is the translation of function [tex]f(x)=\sqrt{x}[/tex]. Option 1 is correct.

Domain is the set of input values.

Function is defined for all x ≥ -3.

Domain = { x |  x ≥ -3 }

Option 2 is incorrect.

Range is the set of output values.

The values of the function are always greater than or equal to -1.

Range = { y |  y ≥ -1 }

Option 3 is correct.

The graph of parent function [tex]f(x)=\sqrt{x}[/tex] shifts 3 units left and 1 unit down to get the graph of g(x). So the function g(x) is defined as

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

Option 4 is incorrect.

The function g(x) can be translated right 3 units and up 1 unit to create the function [tex]f(x)=\sqrt{x}[/tex].

Option 5 is correct.

Answer:

The value of x is -3

Step-by-step explanation:

* Lets explain how to solve the problem

- The slope of a line that passes through points (x1 , y1) and (x2 , y2) is

  [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

* Lets solve the problem

∵ The points (4 , 1) and (x , -6) lie on the same line

∵ The slope of the line is 1

- Let the point (4 , 1) is (x1 , y1) and the point (x , -6) ix (x2 , y2)

∵ x1 = 4 , x2 = x and y1 = 1 , y2 = -6

∴ [tex]m=\frac{x-4}{-6-1}[/tex]

∴ [tex]m=\frac{x-4}{-7}[/tex]

∵ The slope of the line is m = 1

∴ [tex]\frac{x-4}{-7}=1[/tex]

- By using cross multiplication

∴ x - 4 = -7 ⇒ add 4 to both sides

∴ x = -3

* The value of x is -3

the value of x for the point on the line is -3.

The student is asking how to find the value of x for a point on a line with a given slope. Since the slope of the line is 1, we can use the slope formula, which is (y2 - y1) / (x2 - x1) = slope, to find the value of x. Here, we have two points, (4, 1) and (x, -6), and a slope of 1.

Using the formula, we get (-6 - 1) / (x - 4) = 1. Simplifying, we get -7 / (x - 4) = 1. To find the value of x, we solve the equation -7 = x - 4, which gives us x = -3. So, the value of x for the point on the line is -3.

f(x) = x³ – 2x² – x + 2

 0 = x3 – 2x2 – x + 2

 (x-2)(x-1)(x+1)=0

 x1=-1

 x2=1

 x3=2

For this case we must follow the steps below:

We factor the polynomial, starting by factoring the maximum common denominator of each group:

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

We factor the maximum common denominator[tex](x-2):[/tex]

[tex](x-2) (x ^ 2-1)[/tex]

Now, by definition of perfect squares we have:

[tex]a ^ 2-b ^ 2 = (a + b) (a-b)[/tex]

Where:

[tex]a = x\\b = 1[/tex]

Now, we can rewrite the polynomial as:

[tex](x-2) (x + 1) (x-1)[/tex]

To find the roots we equate to 0:

[tex](x-2) (x + 1) (x-1) = 0[/tex]

So, the roots are:

Step-by-step explanation:

For a sine/cosine (sinusoidal) function in the form

y = ASin(Bx-C) + D, we can say

A is the amplitude

360/B is the period

C is the phase shift

D is the vertical translation

The function given is y = 2Sinx

To find the period, we need 360/B. Since "B" is just "1", the period is

360/1 = 360

Answer:

The period of the function [tex]y = 2sinx[/tex] is [tex]2\pi[/tex]

Step-by-step explanation:

The sinosuidal functions have the following form

[tex]y = Asin (bx) +k[/tex]

Where A is the amplitude of the function

k is the vertical displacement

[tex]\frac{2\pi}{b}[/tex] is the period.

In this case we have the function

[tex]y = 2sinx[/tex]

Therefore the amplitude A = 2

The vertical displacement is k = 0

The period is [tex]\frac{2\pi}{1} = 2\pi[/tex] because b=1

Therefore the function completes a cycle every [tex]2\pi[/tex]

The equation that can be used to find the volume of the cylinder is V = π(4.5)²h (option C).

The equation that can be used to find the volume of the cylinder is V = π(4.5)²h (option C). To find the volume of a cylinder, you need to use the formula V = πr²h, where r is the radius of the base and h is the height of the cylinder. In this case, the radius is 4.5 cm and the height is not given, so it is represented as h. By substituting the values into the formula, you get V = π(4.5)²h.
