I don't know whether to distribute -6 or multiply 4x - 6 by 3x + 4. So I'll do both.

1. Multiply

(4x - 6)(3x + 4)

4x (3x + 4) - 6 (3x + 4)

12x² + 16x - 18x - 24

12x² - 2x - 24

2. Distribution

4x - 6(3x + 4)

4x - 18x - 24

-14x - 24

I hope either of my answers helps!

The value of a is 9 and b is 4.5

The measurement of angles and issues relating to angles are covered in the fundamentals of trigonometry. Trigonometry has three fundamental operations: sine, cosine, and tangent. The cotangent, secant, and cosecant are three crucial trigonometric functions that can be derived from these three fundamental ratios or functions. These functions serve as the foundation for all the key ideas in trigonometry.

[tex]sin(60)=\frac{opposite}{hypotenuse} \\\frac{\sqrt{3} }{2}=\frac{\frac{9\sqrt{3} }{2} }{a}\\ a =9\\ tan(60)=\frac{opposite}{adjacent}\\ \sqrt{3}=\frac{\frac{9\sqrt{3} }{2} }{b} \\b=4.5[/tex]

Answer:

FALSE.

Step-by-step explanation:

Given:

To Find:

Formula used:

Using the above formula, we have

h'(x) = [2x*f(x) - f'(x)*x^2]/(f(x))^2

So, h'(3) = [2*3*2 - 4*(3)^2]/(2)^2

h'(3) = (12-36)/4

h'(3) = -24/4 = -6

So, h'(3) = -6 and not -12.

So, the given value is FALSE.

Answer: B) 90º counterclockwise

Step-by-step explanation:

           First, let us look at clockwise vs counterclockwise. Clockwise is in the direction of a clock, spinning around to the right. Counterclockwise is the opposite, spinning to the left.

     A) 90º clockwise

➜ This is 90 degrees to the right.

     B) 90º counterclockwise

➜ This is 90 degrees to the left

     C) 180º

➜ This is directly flipped.

     D) 270º clockwise

➜ This is 270 degrees to the right.

     E) 270º counterclockwise

➜ This is 270 degrees to the left.

           We will look at the answer options and decide which makes the most sense. This looks to be option B, 90º counterclockwise as shown in the image attached.

Unitary method

The unitary method is used to find the value of a single unit from a given multiple. For example, the price of 40 pens is Rs. 400, then how to find the value of one pen here.

Also, once we have found the value of a single unit, then we can calculate the value of the required units by multiplying the single value unit.

We know that,

1 pound = 0.45359237 kilograms ≈ 0.454 kilograms

Hence, using unitary method, we can write,

98 pounds = 98*0.454 kilograms = 44.492 kilograms ≈ 44.5 pounds.

The volume of one fish food cubes is: 1/64 ft³

Using the volume formula, the volume of the shipping box is: 15/4 × 3 × 13/4 = 585/16 ft³

The number of fish food cubes that can be packed in the shipping box is: 2,340 fish food cubes.

The volume of a box = length × width × height

A cube has equal side lengths, therefore, the volume of a cube = (side length)³ = side length × side length × side length.

We are given that the fish food cubes have side lengths of 1/4 ft. Therefore:

Volume of fish food cubes = 1/4 × 1/4 × 1/4

Volume of fish food cubes = (1 × 1 × 1)/(4 × 4 × 4)

Volume of fish food cubes = 1/64 ft³

Using the volume formula, we are given the parameters of the box as:

Length (l) = 3¾ = 15/4 ft

Width (w) = 3 ft

Height (h) = 3¼ = 13/4 ft

Therefore,

Volume of shipping box = 15/4 × 3 × 13/4

Volume of shipping box = (15 × 3 × 13)/(4 × 4) = 585/16 ft³

The number of fish food cubes that can be packed in the shipping box = volume of shipping box/volume of one fish food cube

= 585/16 ÷ 1/64

= 585/16 × 64/1

= (585 × 64)/(16 × 1)

= 37,440/16

= 2,340 fish food cubes.

The number of tiles measuring 20cm by 50cm  that are needed to completely cover a wall 4m by 8m is :320.

First step is to convert the Meters to Centimeters

4m = 400cm

8m = 800 cm

Hence,

4m by 8m = 400 cm × 800 cm

4m by 8m = 320,000 cm²

Second step is to determine the how many tiles are needed

Number of needed tiles =  320,000 cm² / ( 20 cm × 50 cm)

Number of needed tiles =  320,000 cm² /1,000 cm²

Number of needed tiles =  320

Therefore 320 tiles are needed.

The greatest common factor for the given expression is 5z.

What is GCF?
The greatest common factor, which is the product of two or more numbers, is the largest number (GCF). A natural number is created by dividing them by the biggest number (factor). There are a few factors that both share once all the number's factors have been identified. The greatest common factor is the one with the largest number among the common factors. The highest common factor is another name for the GCF (HCF). The highest number that is a factor of all the numbers is known as the greatest common factor of two or more numbers.

Given, the first expression is: y₁ = 70x³z = 5z.14x³ -(i)
Also, the second expression is: y₂ = 45y4z² = 5z.36yz -(ii)

Third angle in a triangle = 180 - (90+36)

= 180-126

= 54°

So,

Third angle in a triangle = 54°

We can use Sin rule,

Then, we get,

[tex]\frac{Sin A}{BC} =\frac{Sin B}{AC} =\frac{Sin C}{AB}[/tex]

Based on the given condition,

We can write,

Sin A = 54°

Sin B = 36°

BC = 5.47

Then,

Sin 54°/5.47 = Sin 36°/AB

Hence, Sin 54° = 0.8090

Sin 36° = 0.5877

[tex]\frac{0.8090}{5.47} =\frac{0.5877}{AB}[/tex]

AB = [tex]\frac{0.5877 * 5.47}{0.8090}[/tex]

AB = [tex]\frac{3.2147}{0.8090}[/tex]

The output value of f( -4 ) in the function f(x) = -x² - 4x + 42 is 42

A function is simply a relationship that maps one input to one output. Every x-value can only have one y-value to qualify as a function.

Given the data in the question;

To find the output value of f( -4 ), replace all the occurrence of x with -4 in the function and simplify.

f( x ) = -x² - 4x + 42

f( -4 ) = -(-4)² - 4(-4) + 42

f( -4 ) = -( 16 ) + 16 + 42

f( -4 ) = -16 + 16 + 42

f( -4 ) =  42

Therefore, the output value of f( -4 ) is 42, this forms an ordered pair of (-4, 42).

where X is the score on a fair, six-sided dice.

P(B or C) means "the probability of rolling an even number or a multiple of 3".

As an even number of a fair, six-sided dice can never be a multiple of 3, the two events B and C are mutually exclusive.

Calculate the probabilities for events B and C.

Event B

Rolling an even number.

[tex]\begin{aligned}\implies \text{P}(X \text{ is even})&=\text{P}(2 \text{ or }4\text{ or }6)\\\\&=\text{P}(X=2)+\text{P}(X=4)+\text{P}(X=6)\\\\& = \dfrac{1}{6}+ \dfrac{1}{6}+ \dfrac{1}{6}\\\\&=\dfrac{3}{6}\end{aligned}[/tex]

Event C

Rolling a multiple of 3.
