The range of the function is {1,-1,10} for function f(x)=2x³−3x .

A relation is a function if it has only One y-value for each x-value.

In a function what can go into a function is called the Domain. What may possibly come out of a function is called the Codomain. What actually comes out of a function is called the Range.

The given function is f(x)=2x³−3x

The domain is {-1,1,2}

Now f(-1)=2(-1)³-3(-1)

=-2+3=1

                               y = -1/2 x + 2

Answer:

Minimum Value: -5

Maximum Value: -1

Interval is [-5, -1]

Step-by-step explanation:

In math the absolute rule for a function f(x) = |x| ≤ a means that the range of values for x can be -a ≤ x ≤ +a

Use |t+3| instead of x in the above rule with a = 2

|t + 3| ≤ 2

⇒ -2 ≤ t + 3 ≤ 2

Subtract 3 from all parts
⇒            -2 - 3 ≤ t + 3 -3 ≤ 2 - 3
This gives

-5 ≤ t ≤ -1

which are the limits for t.

In interval notation this is
[-5, -1]
Minimum Value:   - 5
Maximum Value:  - 1

Answer:

1/4 of the trip

Step-by-step explanation:

The questions is asking what is 1/2 of 1/2 and that would b 1/4

The previous length and width are 20 ft and 12 ft, new length and width are 30 ft and 18 ft thus, option (C) is correct.

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

The scale factor is done due to the unpractical measurement of any figure.

As per the given scale factor 1 in 4ft

Previous length   = 5 × 4 = 20 feet

Previous width = 3 ×4 = 12 ft

As per the given scale factor 1 in 6ft

Previous length = 5×6  = 30 feet

and New width  = 3 × 6 = 18 feet

The 3 side lengths that can form a right triangle are 16, 30, 34

A right triangle (American English) or right-angled triangle (British), or more formally an orthogonal triangle, historically known as a rectangle triangles, is a triangle with one angle that is a right angle (that is, a 90-degree angle), i.e., two sides that are perpendicular.

The hypotenuse is the opposite side of the right angle (side c in the figure). Legs are the sides adjacent to the right angle. Side an is the side adjacent to angle B that is opposed to (or opposite) angle A, whereas side b is the side adjacent to angle A that is opposed to (or opposite) angle A.

By checking the three sides of a triangle are:

16, 30, 34

By using Pythagorean theorem,

√a²+b²=c²

=√16²+30²=34²

=1156=1156

Therefore, the 3 side lengths that can form a right triangle are 16, 30, 34

The height of the tower is 2358.3 feet

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the height of the tower be = A

Let the base of the tower be at a distance of = 500 feet

Now , the angle of elevation is θ = 78°

The height of David's view = 6 feet above

So , the total height of the tower be = A + height of David's eyes

Now , A right angle triangle is formed between the tower, the angle of elevation of David's eyes and his distance from the tower

And , the opposite side = A

Adjacent side = 500 feet

So , from the trigonometric relations

tan θ = opposite side / adjacent side

tan θ = A / 500

Multiply by 500 on both sides , we get

A = tan θ x 500

Substituting the value for θ

A = tan 78° x 500

A = 4.7046 x 500

A = 2352.3 feet

Now , the total height of the tower = A + height of David's eyes

                                                          = 2352.3 + 6

                                                          = 2358.3 feet

Hence , The height of the tower is 2358.3 feet

We are given a complex number in algebraic form, and we would like to find its modulus, |z|.

[tex] \\ \\ [/tex]

[tex] \\ \\ [/tex]

Let's recall that a complex number in algebraic form is written as [tex] \sf z = a + ib [/tex] , where a is its real part and b is its imaginary part.

[tex] \\ [/tex]

The modulus of said complex number is calculated as follows:

[tex] \sf | \sf z| = \sqrt{a^2 + b^2} [/tex]

[tex] \\ [/tex]

[tex] \hrulefill [/tex]

[tex] \\ [/tex]

Let's identify our values:

[tex] \sf z = -2 - 6i \Longleftrightarrow z = \underbrace{\sf -2}_{\sf a} + (\underbrace{\sf -6}_{\sf b})i [/tex]

[tex] \\ [/tex]

Now, substitute these values into our formula:

[tex] \sf | \sf z | = \sqrt{(-2)^2 + (-6)^2} = \sqrt{4 + 36} = \boxed{\sf \sqrt{40}} [/tex]

[tex] \\ [/tex]

While this may be optional, the result can be simplified by using the following property:

[tex]\green{\begin{gathered}\begin{gathered} \\ \boxed { \begin{array}{c c} \\ \blue{ \star \: \sf{\boxed{ \sf Product \: rule \: of \: square \: roots\text{:}}}} \\ \\ \sf{ \diamond \: \sqrt{ab} = \sqrt{a} \times \sqrt{b} } \\ \end{array}}\\\end{gathered} \end{gathered}}[/tex]

The equation of the straight line in fully simplified slope-intercept form: [tex]y = 2x-6[/tex]

A straight line is just a straight line with no bends. A straight line is one that has no bends and continues to infinity on both sides.

A straight line's equation is y=mx+c, where m is the gradient and c is the height at which the line crosses the y axis, commonly known as the y -intercept.

The drawn line cut the x-axis at (3,0) and y-axis at (0,-6)

So, the equation of line is:

    [tex]\frac{x}{3} + \frac{y}{-6} = 1[/tex]

or, [tex]\frac{x}{3} - \frac{y}{6} = 1[/tex]

or, [tex]\frac{2x-y}{6} = 1[/tex]

or, [tex]2x-y =6[/tex]

The population of a town t years from now is given by the formula[tex]P_{t+1} = 1.02(P_t - 550)[/tex]. The current population is 42,000, so there will be approximately 44,031 people in the town 3 years from now.

We are given that the population of the town t years from now is given by the formula

[tex]P_{t+1} = 1.02(P_t - 550)[/tex]

We know that the population of the town is currently 42,000, so we can use this to find the population of the town 1 year from now

P₁ = 1.02(P₀ - 550)

= 1.02(42000 - 550)

= 42669

So there will be 42,669 people in the town 1 year from now.

We can now use this to find the population of the town 2 years from now

P₂ = 1.02(P₁ - 550)

= 1.02(42669 - 550)

= 43349.18 (rounded to 2 decimal places)

So there will be approximately 43,349 people in the town 2 years from now.

Finally, we can use this to find the population of the town 3 years from now

P₃ = 1.02(P₂ - 550)

= 1.02(43349.18 - 550)

= 44031.45 (rounded to 2 decimal places)

Using the attached process, the square roots and cube roots are estimated as follows:

1. √15 = 3.81

2. √44 = 6.6.

3. √81 = 9

4. ∛12 = 2.88.

5. ∛125 = 5

6. ∛320 = 6..8

2)The mistake made by Jan is in the place of 17cm we get 13cm by sing Pythagorean theorem. Therefore, perimeter is 30cm.

3) The error of Joshua is that he miscalculated the third length of the triangle.

From the Pythagorean theorem, we have learned that a²+b²=c²

In mathematics, the Pythagorean Theorem  is the fundamental relationship in Euclidean geometry between the three sides of a right triangle. It states that the area of ​​a square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

The attachment depicts the procedure we will use.

The first step is to make a list of all the perfect squares from 1 to 100, followed by all the perfect cubes from 1 to 1000.

1 to 100 perfect squares; 4, 9, 16, 25, 36, 49, 64, 81, 100

1 to 1000 perfect cubes; 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1000.

1) √15

The perfect squares that are nearest are 9 and 16.

√9 < √15 < √16

⇒ 3 < √15 < 4

Now, √15 is between 3 and 4.

We can estimate √15  as 3.81

2) √44

The perfect squares that are nearest are 36 and 49.

√36 < √44 < √49

⇒ 6 < √44 < 7

Now,√44 is between 6 and 7.

So, we can estimate √44 as 6.6

3) √81

Because this is a perfect square, the approach used to estimate non-perfect squares does not apply. Thus;√81 = 9

4) ∛12

The perfect cubes that are nearest are 8 and 27

Thus; ∛8 < ∛12 < ∛27

⇒ 2 < ∛12 < 3

Now,√12 is between 2 and 3.

So, we can estimate ∛12 as 2.88.

5) ∛125

Because this is a perfect cube, the approach used to estimate non-perfect squares does not apply. Thus;∛125 = 5

6) ∛320

The perfect cubes that are nearest are 216 and 343

Thus; ∛216 < ∛320 < ∛343

⇒ 6 < ∛320 < 7

Now, ∛320 is between 6 and 7.

So, we can estimate ∛320 as 6..8

2) Perimeter of the triangle=L+L+L

Given, Perimeter=5cm+12cm+17cm

=34cm

The mistake he made wrong is,

By using Pythagorean theorem,

√a²+b²=c²

√5²+12²=c²

√25+144=c²

√169=c²

13=c

Therefore, perimeter of the triangle is 5cm+12cm+13cm=30cm

3) First we calculate the third length of the triangle x.

As the triangle is a right triangle we use Pythagorean theorem.

x²=7²+7²

x²=2(7²)

Squaring on both sides, we get

x=√2(7²)

x=7√2

The other shape in the given figure is square.

Therefore the perimeter P is given by,

P=7+x+x+x+7

So, P=7+7√2+7√2+7√2+7

P=14+21√2

Hence, the error of Joshua is that he miscalculated the third length of the triangle.

From the Pythagorean theorem, we have learned that a²+b²=c².
