Answer:

Answer: Answer:

Plane B was farthest away from the airport

Step-by-step explanation:

"This question requires you to visualize the run way as the horizontal distance to be covered, the height from the ground as the height gained by the plane after take of and the distance from the airport as the displacement due to the angle of take off.

In plane A

The take-off angle is 44° and the height gained is 22 ft.

Apply the relationship for sine of an angle;

Sine Ф°= opposite side length÷hypotenuse side length

The opposite side length is the height gained by plane which is 22 ft

The angle is 44° and the distance the plane will be away from the airport after take-off will be represented by the value of hypotenuse

Applying the formula

sin Ф=O/H where O=length of the side opposite to angle 44° and H is the hypotenuse

In plane B

Angle of take-off =40°, height of plane=22miles finding the hypotenuse

Solution

After take-off and reaching a height of 22 ft from the ground, plane A will be 31.67 miles from the airport

After take-off and reaching a height of 22 ft from the ground, plane B will be 34.23 miles away from the airport."

The regular octagon has eight equal sides. Then the area of the regular octagon of side length be 4.6 is 102 ft².

It is a polygon that has eight equal sides. In a regular octagon, the opposite sides are parallel. And its diagonals are also equal and intersect at mid-point.

Given

A regular octagon has a radius of 6 ft and a side length of 4.6 ft.

We know the formula for the regular octagon.

Area of the regular octagon = 2(1 + [tex]\sqrt{2}[/tex]) a²

Where a be the side of a regular octagon.

Then the area of the regular octagon will be.

[tex]\rm Area = 2 (1+\sqrt{2} ) a^2\\\\Area = 2*(1 + 1.414) *4.6^2\\\\Area = 2 * (2.414)* 21.16\\\\Area = 102.16[/tex]

Thus, the area of the regular octagon of side length be 4.6 is 102 ft².

Step-by-step explanation:

the number line : a potentially infinite horizontal line.

it shows all numbers, with 0 in the center, eher we are looking at it. the negative numbers go to the left of 0, with -1, -2, -3, ... going from right to left.

the positive numbers go to the right of 0, with 1, 2, 3 going from left to right.

point S = -14

and the distance to a point R (RS) is 10.

now, on such a line we can always go in 2 directions : left and right.

our starting point is S (-14).

going 10 units to the right (positive direction) we get to -4.

as -14 + 10 = -4

going 10 units to the left (negative direction) we get to -24.

as -14 - 10 = -24

so, R can be at -4 or -24.

Answer:

x = -3

Step-by-step explanation:

Start by distributing the 4 to the terms in the parentheses:

4(-4x)+4(-1)+x+3=44

-16x-4+x+3=44

Combine like terms

-15x-1=44

Add 1 to both sides

-15x-1+1=44+1

-15x=45

Divide both sides by -15

x = -3

Answer: x = -3

Using the given exponential model, it is found that the number of fish in Skipper's Pond at the beginning of the year 2006 is given by:

B. 192

The exponential model for the number of fish in the Pond in x years after 2000 is given by:

[tex]y(x) = 3(2)^x[/tex]

2006 is 6 years after 2000, hence the amount is of y(6), that is:

[tex]y(6) = 3(2)^6 = 192[/tex]

Hence option B is correct.

Answer:

  x = 36°

Step-by-step explanation:

Where a transversal crosses parallel lines, any obtuse angle it creates is supplementary to any acute angle it creates:

  3x +2x = 180°

  5x = 180° . . . . . . . . . collect terms

  x = 180°/5 = 36° . . . . . divide by 5

On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The linear equation is shown below.

[tex]\rm \dfrac{1}{5}x - \dfrac{2}{3}y = 30[/tex]

The equation can be written as

[tex]\rm 3x - 10y = 450\\[/tex]

For y = 15, the value of x will be.

[tex]\begin{aligned} \rm 3x - 10*15 &= 450\\\\\rm 3x - 150 &= 450 \\\\\rm 3x &= 600\\\\\rm x &= 200\\\end{aligned}[/tex]

The value of x is 200.

Thus, option D is correct.

Answer:

x = 5 , y = 15

Step-by-step explanation:

Since the figures are congruent then corresponding sides and angles are congruent , that is

WG = DG ( substitute values )

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

and

∠ WGF = ∠ DGF , that is

15x + y = 90 ( substitute x = 5 )

15(5) + y = 90

75 + y = 90 ( subtract 75 from both sides )

y = 15

Answer:

  AB ≈ 581.6 ft

Step-by-step explanation:

The triangle from point A to the base of the lighthouse to the light beam can be modeled as a right triangle with the side opposite the angle being given. That means the distance from A to the base of the lighthouse is found from the tangent relation:

  Tan = Opposite/Adjacent

  tan(7°) = (105 ft)/A

  A = (105 ft)/tan(7°)

Using similar reasoning, the distance to B is ...

  B = (105 ft)/tan(21°)

Then the distance from A to B is ...

  AB = (105 ft)/tan(7°) -(105 ft)/(tan(21°)) = (105 ft)(1/tan(7°) -1/tan(21°))

  AB ≈ 581.6 ft

_____

Additional comment

We know that 1/tan(7°) = cot(7°) = tan(83°). This means the relation can be written ...

  AB = (105 ft)(tan(83°) -tan(69°))

The graphs of pool A and pool B are illustrations of piece-wise functions

The rate of both pools from t1 to t2, t is 0.

From 0 to t1, the rates of the pools are:

Pool A = A/t1

Pool B = B/t1

Where A represents the gallons of water in the pool and B represents the rate at time t1

From t1 to t2, the rate of both pools is 0.

This is so because both intervals are represented by horizontal lines

Part 3 :

We simply expand the brackets

(a+b)² = (a+b)(a+b)

(a+b)(a+b) = a²+ab+ab+b²  = a²+2ab+b²

This is part 3 done

Part 4:

We simply expand 3 brackets now:

(2x-1)³ = (2x-1)(2x-1)(2x-1)

We do the first 2 brackets first:

(2x-1)(2x-1) = 4x²-2x-2x+1 = 4x²-4x+1

Now we multiply this by the last bracket:

(4x²-4x+1)(2x-1) = 8x³ -4x²-8x² +4x+2x -1  = 8x³-12x²+6x-1

This is part 4 done

Answer: 6 and 8

Step-by-step explanation:

(The top and bottom)

A trapezoid has two bases and two legs. As seen, the lengths that represent the bases of the trapezoid are the parallel sides 8 and 6. This is because they go on straight and never intersect each other, which makes them parallel. The length that represents the height of the trapezoid is 4, which is the straight line that connects both bases.
