6x^2^x^2+x^4

Step-by-step explanation:

Answer:

Yes your answer is correct

Step-by-step explanation:

First of all you multiply 3x with 2x which equals 6x power 2 because we sum the power. Then we multiply 6x power 2 with x power 4 which equals 6x power 6 because X is 1X so the answer is 6X power 6

Answer:

Step-by-step explanation:

No, not quite. She's close.

The middle term (often called the linear term) is + which means that the absolute value of the factors must be plus.

(x + 5)(x - 3) is what should should think.

x + 5 = 0

x = - 5

x + 2 = 0

x = - 2

(x + 5)(x - 2)

x^2 - 2x + 5x - 10

x^2 + 3x - 10

Answer:

Option B

Step-by-step explanation:

It's given that p + q has a value of [tex]\frac{12}{5}[/tex]

So the equation representing the relation will be,

p + q = [tex]\frac{12}{5}[/tex] --------(1)

Value of p is [tex]\frac{4}{5}[/tex]

p = [tex]\frac{4}{5}[/tex]

By substituting the value of p in the equation (1),

[tex]\frac{4}{5}+q=\frac{12}{5}[/tex]

q = [tex]\frac{12}{5}-\frac{4}{5}[/tex]

q = [tex]\frac{8}{5}[/tex]

Therefore, Option B will be the correct option.

Step-by-step explanation:

From the question we are told that:

Initial bearing [tex]\angle _1=21 \textdegree[/tex]

Initial distance [tex]d_1=99miles[/tex]

Final bearing [tex]\angle _2=227 \textdegree[/tex]

Let [tex]\triangle OAB[/tex] be the perimeter travailed

[tex]\angle OAB=90+21=111 \textdegree\\\angle ABO=270-227=43 \textdegree[/tex]

Generally the equation for OB using sine rule is mathematically given by

[tex]OB=99*\frac{sin111}{sin43}[/tex]

[tex]OB=135.52miles[/tex]

Therefore the helicopter flight on the final leg of its​ journey is

[tex]OB=135.52miles[/tex]

Answer:

103.62

Step-by-step explanation:

Formula: v = πr²[tex]\frac{h}{3}[/tex], v = πr²h

Given: π = 3.14, r = 3, h = 5

Sub: 3.14(3)²[tex]\frac{5}{3}[/tex]

Simplify: 3.14(9)[tex]\frac{5}{3}[/tex]

Simplify: (28.26)[tex]\frac{5}{3}[/tex]

Solve: 47.1

Given: π = 3.14, r = 3, h = 6

Sub: 3.14(3)6

Simplify: (9.42)6

Solve: 56.52

V = v1 + v2

V = 47.1 + 56.52

V = 103.62

The total volume of the figure is 103.62

Answer:

The area of the trapezoid is 108 square feet

Step-by-step explanation:

The given vertices of the trapezoid are;

(-6, 9), (-6, 6), (3, -9, and (3, 12)

Let the letters A, B, C, and D represent the vertices of the trapezoid, we have;

A(-6, 9), B(-6, 6), C(3, -9) and D(3, 12)

The drawing of the trapezoid on the coordinate plane created with MS Excel is attached

The area of a trapezoid, [tex]A_T[/tex] = (a + b)×h/2

Where;

'a', and 'b' = The length of the bases (parallel sides)

h = The height of the trapezoid (The distance between the bases)

Let 'a' represent the length of the long base CD and let 'b' represent the length of the short base AB

a = √((-9 - 12)² + (3 - 3)²) = 21

∴ a = 21 feet

Similarly, we have;

b = √((9 - 6)² + (-6 - (-6))² = 3

The height, h = The distance between AB and CD = AE

We note that sides AB and CD are parallel to the y-axis, therefore, the height which is the perpendicular distance to the between AB and CD will be parallel to the x-axis

Therefore, the t-coordinates of the points A and E are both equal to 9 and the length of AE = √((3 - (-6))² + (9 - 9)²) = 9

The height of the trapezoid, AE = 9 feet

∴ The area of the trapezoid, A = (21 + 3) × 9/2 = 108

The area of the trapezoid, [tex]A_T[/tex] = 108 ft.²

Answer: Subtract 3 from each side of the equation(A)

Step-by-step explanation:

3n2−15n=3

1:Subtract 3n2 from both sides.

-15n=3-3n2

2:Divide both sides by -15.

-15n/-15=3-3n2/-15

3:Dividing by −15 undoes the multiplication by −15.

n=3-3n2/-15

4:Divide 3−3n 2 ​ by −15

n=n2-1/5

An equation is formed of two equal expressions. The first step in solving the given equation is to Subtract 3 from each side of the equation.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of the equation 3n²-15n=3 can be done as,

3n²-15n=3

3n²-15n-3=3-3

3n²-15n-3=0

(3n²-15n-3)/3=0/3

n²-5n-1=0

Therefore, the first step in solving the given equation is to Subtract 3 from each side of the equation.

Answer:

600ft²

Step-by-step explanation:

Oh boy, this is gonna be a long one, so proceed with caution:

So we're gonna start with the one to the very left, we can split this into three different rectangles:

So we got the length of the bottom minus the length we don't want there because we're doing the big rectangle:

35 - 10 = 25

25 x 20 = 500

So we're just gonna keep that on a back burner, cause now we gotta do the two smaller ones:

So we got the measure from the one side, but we gotta subtract the 10 from the other side:

20 - 10 = 10

10 x 10 = 100

Now we gotta add that all up:

500 + 100 = 600

So the area of the first shape is 600ft²

Answer: 8

Step-by-step explanation:

Answer:

(11/2)² or 121/4 would be added to the equation x ² +11x+30=0,  to "complete the square".

Step-by-step explanation:

x 2 +11x+30=0

Write the equation in the form of the square

(x)^2 + 2(x) (11/2)  + (11/2)^2  + 30 - 121/4= 0

Square of the first element + 2 into first element into 2nd element + square of 2nd element gives the complete square formula.

How we obtained the second element?

The mid term broken must always be equal to the mid term given.

Hence

2(x)    can only be equal to 11x if we multiply it by 11 and divide it with 2.

So the second term must be 11/2 .

To complete the square this second term ( 11/2)² is added and then subtracted to keep the equation equal to the original equation.

(x)^2 + 2(x) (11/2)  + (11/2)^2  + 30 - 121/4= 0

Putting it in the form of square

(x+ 11/2)^2  + 120-121/4= 0

Taking LCM and solving

(x+ 11/2)^2   - 1/4= 0

(x+ 11/2)^2  = 1/4

Taking square root on both sides

(x+ 11/2)   = ± 1/2

x= - 11/2  ± 1/2

x= -10/2= -5

x= -12/2= -6

Answer:

[tex] \boxed{A ≈ 58.1 \: cm^{2}} [/tex]

Step-by-step explanation:

When given a regular polygon.

s = a × 2 tan (π / n [radians]).

s = a × 2 tan (180 / n [degrees])

A = (n × s × a) / 2

Where s is the side length, n is the number of sides, a is the apothem length, and A is the area.

You may also see A = p × a.

Where p is the perimeter, the perimeter is the same as n × s.

The apothem is also known as the inradius.

______________________________________

Given a regular pentagon which has 5 sides, and an apothem of 4 cm.

s = 4 × 2 tan (180 / 5) = 4 × 2 × (0.726542528) = 8 × (0.726542528) = 5.81234022404.. ≈ 5.8 cm.

Now that we have sufficient information, we can now solve for the area.

A = (n × s × a) / 2

A = (5 × 5.81234022404.. cm × 4) / 2

A = (20 × 5.81234022404.. cm) / 2

A = (116.236804481.. cm²) / 2

A = 58.1234022404.. cm²

A ≈ 58.1 cm²

The area of the regular polygon is the amount of space it covers

The area of the regular polygon is 58.1 square centimeter

The given parameter is:

[tex]\mathbf{a=4}[/tex]

Start by calculating the side lengths using

[tex]\mathbf{s = 2a\ tan (\frac{180}{ n} )}[/tex]

Where n represents the number of sides.

In this case

[tex]\mathbf{n =5}[/tex]

So, we have:

[tex]\mathbf{s = 2a\ tan (\frac{180}{ 5} )}[/tex]

[tex]\mathbf{s = 2a\ tan (36)}[/tex]

Substitute 4 for (a)

[tex]\mathbf{s = 2 \times 4\ tan (36)}[/tex]

[tex]\mathbf{s = 8\ tan (36)}[/tex]

[tex]\mathbf{s = 5.8123}[/tex]

The surface area is then calculated as:

[tex]\mathbf{A = \frac{n \times s \times a}{ 2}}[/tex]

So, we have:

[tex]\mathbf{A = \frac{5 \times 5.8123 \times 4}{2}}[/tex]

[tex]\mathbf{A = 58.123}[/tex]

Approximate

[tex]\mathbf{A = 58.1}[/tex]

Hence, the area of the regular polygon is 58.1 square centimeter
