The solution to the x/-3≤ 3 inequality is x ≤ -9.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than. In mathematics, an inequality is a relationship between two numbers or other mathematical expressions that results in an unequal comparison. Inequalities are the name given to certain algebraic mathematical expressions.

The exponential function for the given graph having points (2, 16) is f(x) = [tex]4^{x}[/tex].

The exponential function is a type of mathematical function that can be used to determine whether something is increasing or decreasing exponentially, such as population, money, or price. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base.

Exponents are used in exponential functions, as the name indicates.

The given point on the graph is (2, 16).

The given function is f(x) = [tex]a^{x}[/tex]

From graph, (x, y) = (2, 16)

Put the value of (x, y) = (2, 16) in f(x) = [tex]a^{x}[/tex]

16 = a²

a = √16

a = 4

So, the function is

Answer:

1 and 3 equal 126 (vertical angle)

2 and 4 equal 54 (supplemental angles 180-126)

Step-by-step explanation:

Answer:

angle 2: 54 degrees

Angle 3: 126 degrees

Angle 4: 54 degrees

Step-by-step explanation:

since angle 1 is 126 degrees we can find angle 2 since it’s right next to it like that the 2 angles added equal 180 degrees so we just subtract from 180

180-126

Angle 2 is 54 degrees

Since angle 3 is across angle 1 they are equivalent so angle 3 is 126 degrees

Since angle 4 is across angle 2 they are equivalent so angle 4 is 54 degrees

If a company’s stock was selling at 35$ a share a month later it was selling at 14$ a share the percentage loss is 60%

The company's initial share price = $35 per share

The company's new share price = $14 per share

Therefore the share price decreased from $35 to $14,  we have to find the percentage loss

The percentage loss = [(The company's initial share price - The company's new share price) / The company's initial share price ] × 100

Substitute the values in the equation

The percentage loss = [(35-14) / 35] × 100

= (21/35)×100

= 0.6 × 100

= 60%

Hence, if a company’s stock was selling at 35$ a share a month later it was selling at 14$ a share the percentage loss is 60%

(a) By expanding, the derivative of the polynomial is f'(x) = 12x² - 6x + 8

(b) Using the product rule, the derivative of the polynomial is f'(x) = 12x² - 6x + 8

(c) The expressions for the derivative in (a) and (b) are the same

From the question, we are to determine the derivative of the given polynomial.

The given polynomial is f(x) = (x² + 2)(4x - 3)

(a) By expanding the polynomial, we get

f(x) = (x² + 2)(4x - 3)

f(x) = x²(4x - 3) +2(4x - 3)

f(x) = 4x³ - 3x² + 8x - 6

∴ f'(x) = 12x² - 6x + 8

(b) By using the product rule

f(x) = (x² + 2)(4x - 3)

g(x) = x² + 2

and

h(x) = 4x - 3

Thus,

g'(x) = 2x

h'(x) = 4

From the product rule

f'(x) = g(x).h'(x) + h(x).g'(x)

f'(x) = (x² + 2)(4) + (4x - 3)(2x)

f'(x) = 4x² + 8 + 8x² - 6x

Collect like terms

f'(x) = 4x² + 8x² - 6x + 8

∴ f'(x) = 12x² - 6x + 8

(c) The expressions are the same

Hence,

The derivative is f'(x) = 12x² - 6x + 8

a) The Factor of -4x² + 12x is 4x( -x +3)

b) The multiplication of (4.8x)(4x) is  19.2x²

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

-4x² + 12x

Now, factorizing

4x²= 2 x 2× x × x

12x = 2 ×2× 3 × x

So, the factor can be

-4x² + 12x

= -2 x 2× x × x + 2 ×2× 3 × x

= 4x( -x +3)

The distance between the two airlines changing at 3:00 p.m is 374mi/hr

Here, the trajectory of the 2 planes will form a right angle at the airport.

Let 'a' be the distance of the east bound plane travelled past the airport and b be the distance of the south bound plane travelled past the airport and c is the horizontal distance between the two planes

a² + b² = c²

differentiating both sides with respect to time

2a da/dt + 2b db/dt = 2c dc/dt

The speed of both airlines is given,

da/dt = 520mi/hr and  db/dt  = 560mi/hr

At 12 pm the east bound plane has been flying post airport

at 3 pm, the distance = 3 x da/dt = 2(520) = 1560

At 1 pm the east bound plane has been flying post airport

at 3 pm, the distance = 2 x db/dt = 2(560) = 1120

c = √(a² + b²)

c = √(1560² + 1120²)

c = 1920.41

fast is the distance between them changing dc/dt

dc/dt = (3a da/dt + 2b db/dt)/2c

= (1560 x 520+ 1120x560)/1920

dc/dt = 374

Therefore, the distance between them changing at 3:00 p.m is 374mi/hr

The total spent to paint the mural which is circular with a diameter of 45 feet will be $100.67.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

The longest line which can be drawn inside the circle will be the diameter.

The perimeter of the circle = 2πr where r is the radius of the circle.

As per the given,

Diameter = 45 feet  so radius 45/2 = 22.5 feet

Area of circle = πr² = π(22.5)² = 1590.43 feet²

Since one gallon covers  300 square feet.

Number of gallons needed to cover the whole area,

1590.43/300 = 5.30

Cost of one gallon = $18.99

Total spend = 5.30 × 18.99 = $100.67

The indices (8.1)(8.1²)⁴ simplifies to 8.1⁹

Index is the power or exponent which is raised to a number or a variable. For example, in number 3², 2 is the index of 3. The plural form of index is indices

Given:  (8.1)(8.1²)⁴

To simplify these indices, we are going to apply one of the indices, which is expressed below:  (4³)² = 4³ ˣ ² = 4⁶. We basically multiply the powers

We also need another law which is expressed below:

3⁶ x 3⁴ = 3⁶⁺⁴ = 3¹⁰

If two indices with the same base (in case 3) are being multiplied, you can simplify by taking one of the bases and then add the powers  

Thus, to simplify (8.1)(8.1²)⁴:

(8.1)(8.1²)⁴ = (8.1)(8.1)²ˣ⁴

           =  (8.1)(8.1)⁸

            = 8.1¹ × 8.1⁸

            = 8.1¹⁺⁸

            =   8.1⁹

Therefore, (8.1)(8.1²)⁴ simplifies to 8.1⁹. The 4th option is the answer

The parabola equation in its vertex form is f(x) = -3(x - 5)² + 9

From the question, we have the function to be

f(x) = 3x²

Also, we have the vertex to be given as

Vertex = (5, 9)

A quadratic function takes the form:

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

So, we can rewrite f(x) = 3x² as follows

f(x) = 3(x - 0)² + 0

By comparing the equations, we have

a = 3

Also, by comparison, we have

(h, k) = (5, 9)

Substitute a = 3 and (h, k) = (5, 9) in f(x) = a(x - h)² + k

So, we have

f(x) = 3(x - 5)² + 9

Hence, the equation of the parabola is f(x) = -3(x - 5)² + 9

C: Currency in circulation

D: Checkable Deposits

M1=C+D = 1200+1600= 2800

C: Currency in circulation

D: Checkable Deposits

Currency Deposit Ratio= C/D = 1200/1600 = 0.75

The case of the velocity vectors, v₁ and v₂ that yield the largest absolute value of Δv = v₂ - v₁ is the case of option B. b

A velocity vector provides an indication of s particle's speed and direction of motion.

The vectors in the question can be expressed using vector notation as follows;

a) [tex]\vec{v_1}[/tex] = i + j

[tex]\vec{v_2}[/tex] = i + j

Δv = v₂ - v₁ is therefore;

v₂ - v₁ = i - i + j - j = 0

Δv = 0

b)  [tex]\vec{v_1}[/tex] = i + j

[tex]\vec{v_2}[/tex] = -i - j

Δv = v₂ - v₁ is therefore;

v₂ - v₁ = i - (-i) + j - (-j) = 2·i + 2·j

Δv = 2·i + 2·j

c)  [tex]\vec{v_1}[/tex] = i + j

[tex]\vec{v_2}[/tex] = i - j

Δv = v₂ - v₁ is therefore;

v₂ - v₁ = i - i + j - (-j) = 2·j

Δv = 2·j

d)  [tex]\vec{v_1}[/tex] = i + j

Comparing the vertical and horizontal lengths of the arrows, indicates;

[tex]\vec{v_2}[/tex] ≈ -1.2·i - 0.5·j

Δv = v₂ - v₁ is therefore;

v₂ - v₁ = i - (-1.2·i) + j - (-0.5·j) = 2.2·i + 1.5·j

Δv = 2,2·j + 1,5·j

Option (b) and (d) have the largest values, however, their magnitudes are;

b) |Δv| = √(2² + 2²) = 2·√2 ≈ 2.83
