please help, i cannot find an answer :( (Ill give crown or wtv)
Answer:
Is this correct??
if yes then reply
Answer/Step-by-step explanation:
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

If h(x)=x^2/f(x) and f(3) = 2 and f'(3) = 4, then h' (3) = -12.
true
false
Answer:
FALSE.
Step-by-step explanation:
Given:
h(x)=x^2/f(x) f(3) = 2 f'(3) = 4To Find:
Whether h'(3) = -12 or not.Formula used:
For a function y = f(x)/g(x), the differentiation of y is defined as y' = [f'(x)*g(x) - g'(x)*f(x)]/(g(x))^2. This is know as quotient rule of differentiation.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.

Find the Greatest Common Factor (GCF):
70x³z, 45y4z²
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)
Comparing (i) and (ii), the greatest common factor for y₁ and y₂ is 5z.
Thus, the greatest common factor for the given expression is 5z.

Part 2: Find the volume of the shipping box using the total number of fish food cubes. Step 1: Find the volume of the fish food cube. Remember to include units. Volume of the fish food cube = _____ × _____ × _____ = __________ Step 2: Find the volume of the shipping box using your answer from Part 1. Remember to include units. Volume of the shipping box = _____ × _____ = __________ Part 3: Find the volume of the shipping box using a volume formula. Remember to include units. V = l × w × h = _____ × _____ × _____ = __________ Are your answers for the volume of the shipping box in Parts 2 and 3 equal? Why or why not?
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.
What is the Volume of a Box and a Cube?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.

E) 270º counterclockwise
is 2 correct answers ❗️
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.

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

What is the output value of f( -4 ) in the given function?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;
f( x ) = -x² - 4x + 42f( -4 ) = ?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 ) = -( 16 ) + 16 + 42
f( -4 ) = -16 + 16 + 42
f( -4 ) = 42

Based on the given condition,
We can write,
Sin A = 54°
Sin B = 36°
BC = 5.47
