anyone know questions 2, 3, 4, 5 and 6?

Answer:

they weigh 2 pounds each

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

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]

Step-by-step explanation:

The length of the side CD of the triangle CDE is CD = 8.3 m

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be represented as CDE

Now , the length of the side CE = 19m

The measure of the angle ∠DCE = 64°

So , the length of the side CD is given by the trigonometric relations is

cos θ = adjacent / hypotenuse

Substituting the values in the equation , we get

cos 64° = x/19

Multiply by 19 on both sides of the equation , we get

x = 19 x cos 64°

On simplifying the equation , we get

x = 19 x 0.4384

x = 8.3296 m

x = 8.3 m

Therefore , the value of x is 8.3 m

Hence , the length of the side CD is 8.3 m

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

Answer:

The dimension of the sandbox is (2x+1) by (x - 3)

Step-by-step explanation:

It seems the complete question will be:

The area of sandbox in park is represented by 2X^2-5x-3 find the dimensions of the sandbox in terms of x.

Step-by-step explanation:

From the question, the given expression is 2X^2-5x-3. This can be rewritten as

[tex]2x^{2} -5x-3[/tex]

If the area of the sandbox in park is represented by this expression, then the dimensions of the sandbox will be the product of the factors. To determine the factors, we will factorize the given quadratic expression.

Factorizing the expression [tex]2x^{2} -5x-3[/tex], we get

[tex]2x^{2} -6x+x-3[/tex]

[tex]2x(x-3)+1(x-3)[/tex]

[tex](2x+1)(x-3)[/tex]

Hence, the dimension of the sandbox is (2x+1) by (x - 3)

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

Question:

Find the surface area of the following figure below. Use 3.14 for pi

Answer:

9

Step-by-step explanation:

The circle has the same value of the side which is 3 so the length and width is 3 too. So the formal is L x W = Area. So this means 3 x 3 = 9

Answer:

0.512 = 51.2%

1.94 = 194%

0.9 = 90%

1.33 = 133%

1.14 = 114%

1.42 = 142%

Step-by-step explanation:

 To convert a decimal to a percent, move the decimal point two spaces to the right.

 Converting a percent to a decimal works the same way, except you move the decimal two spaces to the left.

[Note: If there aren't enough numbers to go over two spaces, place a zero at the end. For example, if you have 0.9, and you need to convert it into a percent, you'd place a zero after the 9, making it 0.90.]

Answer:

Amount invested = $15,000 (Approx.)

Step-by-step explanation:

Given:

Amount of interest received = $6,159

Rate of interest = 3.5%

Number of year = 10 year

Find;

Amount invested

Computation:

Using compound interest formula

I = P[(1+r)ⁿ - 1]

6,159 = Amount invested[(1+3.5%)¹⁰ - 1]  

6,159 = Amount invested[(1+0.035)¹⁰ - 1]  

6,159 = Amount invested[(1.035)¹⁰ - 1]  

Amount invested = $15,000 (Approx.)

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

[tex]x = -2[/tex]

Step-by-step explanation:

Given

[tex]y=\frac{-3}{(x+2)^2}+3[/tex]

[tex]y = - 3[/tex]

[tex]y = 0[/tex]

The question has confusing details because the height of a shape do not relate to the given parameters.

A more complete question found on the brainly shows that the complete question asks for the asymptote of the function.

To do this, we have:

[tex]y=\frac{-3}{(x+2)^2}+3[/tex]

Take LCM

[tex]y = \frac{-3 + 3(x+2)^2}{(x+2)^2}[/tex]

Equate the denominator to 0

[tex](x + 2)^2 = 0[/tex]

Take square roots of both sides

[tex]x + 2 = 0[/tex]

Solve for x

[tex]x = -2[/tex]

Hence, the asymptote is at [tex]x = -2[/tex]

8 is the answer \(-ㅂ-)/ ♥ ♥ ♥(╯°□°）╯︵ ┻━┻

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
