Expand the polynomial 6x(x–3)–x(2–x)

Answer:

84ft

Step-by-step explanation:

w = 2/3(L)

if 280 feet of fencing can enclose the garden,therefore the perimeter is 280 feet

perimeter = 2L + 2W

but W=2/3(L)

therefore, perimeter = 2L + 2(2/3L)

P= 2L + 4/3(L)

P= 10/3(L)

but P= 280

therefore 280= 10/3(L)

L = (3×280)÷10

L= 84 feet

Answer:

Slope intercept form is

[tex]y=\frac{4}{3} x- \frac{19}{3}[/tex]

Step-by-step explanation:

Answer:

The ans from the bottom left

cos2(θ) + sin2(θ) = 1

sec(θ) = 1/cos(θ)

cot(θ) = cos(x)/sin(θ)

sin(θ) = -3/4

cos2(θ) + sin2(θ) = 1

cos2(θ) = 1 - sin2(θ)

cos2(θ) = 1 - 9/16 = 7/16

cos(θ) = ±√(7/16) = √7/16  (cosine is positive in Q IV)

sec(θ) = 1/cos(θ) = 4/√7

cot(θ) = cos(θ)/sin(θ) = (4/√7)/(-3/4) = -16√7/21

The exact values of secθ = 4/√7 and cotθ = -16√7/21

Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.

Given that,

sinθ = -3/4

∵sin²(θ) +cos²(θ) = 1

∴cos²(θ) = 1 - sin²(θ)

cos(θ) = √(1 - sin²(θ))

cos²(θ) = √(1 - 9/16 )

cos(θ) = ±√(7/16) = √7/4  (cosine is positive in quadrant IV )

sec(θ) = 1/cos(θ) = 4/√7

∵cot(θ) = cos(θ)/sin(θ)

∴cot(θ)= (4/√7)/(-3/4)

cot(θ) = -16√7/21

The exact values of secθ = 4/√7 and cotθ = -16√7/21

Answer:

Value of Number = 8

Step-by-step explanation:

Consider the equation below;

[tex]If x - " A Number " -\\( 2 * x ) - 5 = x + 3,\\[/tex]

Now using this equation let us solve for x;

[tex]( 2 * x ) - 5 = x + 3 - Take ( 2 * x ) - 2x,\\2x - 5 = x + 3 - Add 5 on Either Side,\\2x = x + 8 - Subtract x From Either Side,\\\\x = 8, ( Solution )\\\\Conclusion ; x = 8[/tex]

Knowing this, we can say;

[tex]Value of Number = 8,\\if x - Value of Number ( Given ),\\\\Solution ; Value of Number = 8[/tex]

The value of unknown number x will be 8.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have been given a statement as;

"five less than 2 times a number is equal to the sum of the number and 3"

Let the unknown number be x.

So, from the given statement,

2x- 5 = x + 3

Subtract x on both sides;

2x- 5 = x + 3

2x- 5 -x = x + 3 - x

x - 5 = 3

Add 5 on both sides;

x - 5 = 3

x = 8

Therefore, the value of unknown number x will be 8.

Answer:

The Answer is: B= about 1.44mm^3

Step-by-step explanation:

hope I could help you out :)

The volume of bubble is 1.44 cubic mm.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

Given data as :

Radius of the Bubble (r) = 0.7 mm

Volume of the bubble is given by the formula

[tex]r =\sqrt[3]{\dfrac{3v}{4\pi} }[/tex]

Taking cube on both sides

r³ = 3v/4π

Rearrange the equation,

v = 4πr³/3

Substitute the value of r in the above equation,

v = 4π(0.7)³/3

Substitute the value of π = 3.14

v = 4(3.14)(0.343)/3

v = 4.3/3

v = 1.44

Hence, the volume of bubble is 1.44 cubic mm.

  B.  6, 8, 10 2/3, 14 2/9, 18 26/27

Step-by-step explanation:

The recursive relation tells you the first term is 6, eliminating choice A immediately.

It also tells you each term is 4/3 the previous term, so the sequence cannot be a sequence of integers*, eliminating choices C and D.

If you do the math, you find the terms of Choice B are correct:

_____

* Unless you start with a very large power of 3, repeatedly multiplying by 4/3 will eventually end with powers of 3 in the denominator and some multiple of powers of 2 in the numerator. Such a ratio cannot be an integer.

Answer:

4)  2(x - 3)^2 + 2(y + 5)^2 = 96.

Step-by-step explanation:

2x^2 – 12x + 2y^2 + 20y – 28 = 0

2(x^2 – 6) + 2(y^2 + 10y) = 28

2 ( (x - 3)^2 - 9)) + 2((y + 5)^2 - 25) = 28

2(x - 3)^2 - 18 + 2(y + 5)^2  - 50 = 28

2(x - 3)^2 + 2(y + 5)^2 = 28 + 18 + 50

2(x - 3)^2 + 2(y + 5)^2 = 96

Answer:

[tex]4) 2(x-3)^2+2(y+5)^2=96[/tex]

Step-by-step explanation:

[tex]2x^2 -12x +2y^2 + 20y - 28 = 0[/tex]

It basically represents a circle.

Equation of circle

[tex]\left(x-a\right)^2+\left(y-b\right)^2=r^2\:[/tex]

[tex]2x^2-12x+2y^2+20y=28[/tex]

[tex]$\frac{1}{2} (2x^2-12x+2y^2+20y)=28 \cdot \frac{1}{2} $[/tex]

[tex]x^2-6x+y^2+10y=14[/tex]

Organize the variables

[tex]\left(x^2-6x\right)+\left(y^2+10y\right)=14[/tex]

Now we have to complete the square for both groups:

[tex]\left(x^2-6x+9\right)+\left(y^2+10y+25\right)=14+9+25[/tex]

[tex]\left(x-3\right)^2+\left(y+5\right)^2=14+9+25[/tex]

[tex]\left(x-3\right)^2+\left(y+5\right)^2=48[/tex]

Now, I would proceed with:

[tex]\sqrt{48} =\sqrt{2 \cdot 2 \cdot 2 \cdot 2 \cdot 3} =4\sqrt{3}[/tex]

[tex]\left(x-3\right)^2+\left(y+5\right)^2=(4\sqrt{3} )^2[/tex]

We got the center and the circle radius

[tex]\left(3,\:-5\right)\\r=4\sqrt{3}[/tex]

But this is not what you want:

So, just multiply both sides by 2 and you'll get:

[tex]2\left(x-3\right)^2+2\left(y+5\right)^2=96[/tex]

Answer:

40.5 cm²

Step-by-step explanation:

Given the ratio of sides of 2 figures = a : b

then the ratio of areas = a² : b²

Here the ratio of Δ A : Δ B = 2 : 1, thus

ratio of areas = 2² : 1² = 4 : 1

That is the area of Δ A is 4 times area of Δ B, so

area of Δ B = 162 ÷ 4 = 40.5 cm²
