Answer: (7x + 1)(x + 7)

Step-by-step explanation:

[tex]$$Factor the following:$$7 x^{2}+50 x+7$$Factor the quadratic $7 x^{2}+50 x+7$. The coefficient of $x^{2}$ is 7 and the constant term is 7. The product of 7 and 7 is 49 . The factors of 49 which sum to 50 are 1 and 49. So:\\\\ $7 x^{2}+50 x+7\\=7 x^{2}+49 x+x+7\\=7(7 x+1)+x(7 x+1)$ \\\\Factor $7 x+1$ from $7(7 x+1)+x(7 x+1)$ :$$\\\\Answer:(7 x+1)(x+7)$$[/tex]

Since the figure is a trapezoid, we must use the trapezoid area formula, [tex]A = (b_1 + b_2) / 2 * h[/tex]. By doing so, we can plug in the shown numbers on the image. After that, we multiply.

[tex]A = (8 + 14) / 2 * 5[/tex]

[tex]A = 22/2 * 5[/tex]

[tex]A = 11 *5[/tex]

[tex]A = 55^2[/tex]

The area of the trapezoid is 55 squared yards.

Answer:

224 cm²

Step-by-step explanation:

Look at the figure below.

All sides are in cm. All areas are in cm².

Triangle A:

A = bh/2 = 8 × 21 / 2 = 84

Rectangle B:

A = LW = 9 × 8 = 72

Rectangle C:

A = LW = 4 × 5 = 20

Triangle D:

A = bh/2 = 6 × 16 / 2 = 48

Total area = 84 + 72 + 20 + 48 = 224

Answer: 224 cm²

S₁₃ = 455

Step-by-step explanation:

the sum to n terms of an arithmetic is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

We require to find both a₁ and d

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

given a₄ = 20 and a₁₃ = 65 , then

a₁ + 3d = 20 → (1)

a₁ + 12d = 65 → (2)

subtract (1) from (2) term by term to eliminate a₁

9d = 45 ( divide both sides by 9 )

d = 5

substitute d = 5 into (1) and solve for a₁

a₁ + 3(5) = 20

a₁ + 15 = 20 ( subtract 15 from both sides )

a₁ = 5

Then

S₁₃ = [tex]\frac{13}{2}[/tex] [ (2 × 5 ) + (12 × 5 ) }

     = 6.5 (10 + 60)

     = 6.5 × 70

Step-by-step explanation:

The force vector F in terms of i and j, considering it's magnitude and angle, is represented by:

[tex]V = 11\sqrt{2}i + 11\sqrt{2}j[/tex]

Given a magnitude M and angle [tex]\theta[/tex], the a vector V can be represented as follows:

[tex]V = M\sin{\theta}i + M\cos{\theta}j[/tex]

In this problem, we have that the parameters are as follows:

[tex]M = 22, \theta = 45^\circ[/tex]

Hence:

[tex]V = 22\sin{45^\circ}i + 22\cos{45^\circ}j[/tex]

[tex]V = 22\frac{\sqrt{2}}{2}i + 22\frac{\sqrt{2}}{2}j[/tex]

[tex]V = 11\sqrt{2}i + 11\sqrt{2}j[/tex]

The values of r and w will be 50 and 140 degrees.

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

From the Exterior Angle of a Triangle Property;

38° + 103° = w

w = 140°

Let x be the exterior angle so that

x = r + 90°

Similarly,

By vertically opposite angle;

w = x

So, x = r + 90°

140 = r + 90°

r = 140 - 90

r = 50

Hence, the values of r and w will be 50 and 140 degrees.

Answer:

  (a)  north: 172.5 mph; west: 298.8 mph

  (b)  363.9 mph at 298.9°

Step-by-step explanation:

The components of velocity are found using the formula for polar to rectangular coordinate conversion. The actual ground speed will be the result of adding the velocity vectors of the airplane and wind.

__

The usual formula for converting polar coordinates (r; θ) to rectangular coordinates (x, y) is ...

  (x, y) = r(cos(θ), sin(θ))

When this formula is used with bearing angles, the resulting components are (north, east).

The airplane velocity components are ...

  north: 345·cos(300°) = 172.5 . . . . mph

  east: 345·sin(300°) ≈ -298.8 . . . . mph (or 298.8 mph to the west)

__

The sum of the two velocity vectors is found by a calculator to be ...

  345∠300° +20∠280° = 363.9∠298.9°

If you wanted to calculate this by hand, you would find the components of the wind speed, add them to the components of the plane speed, and convert the rectangular components back to polar coordinates. The usual way that is done is using the formula ...

  r = √(x² +y²)

  θ = arctan(y/x) . . . . paying attention to quadrant

If you use x=northerly component, y=easterly component, then the resulting angle is the bearing angle.

_____

Additional comment

Some calculators are able to convert directly between (x, y) coordinates and (r; θ) coordinates. The calculator shown in the attachment converts (r; θ) coordinates to/from complex numbers. For the purpose here, the real part of the number is the northerly component, and the imaginary part is the easterly component.

The conversion to a complex number is x +iy = r(cos(θ) +i·sin(θ)), sometimes abbreviated r·cis(θ). The notation used here is even more compact: r∠θ. Conveniently, the calculator we used is able to employ this notation.

Therefore, to find the maximum value of a - b, subtract the smallest value of b from the largest value of a:

The sum of the arithmetic series with the parameters  t1 = -2, t3 = 7, and n = 15 is 442.5

The given parameters are:

t1 = -2

t3 = 7

n = 15

Start by calculating the common difference using:

Tn = t1 + (n- 1)d

So, we have:

7 = -2 + (3 - 1) * d

Evaluate

7 = -2 + 2d

Add 2 to both sides

2d = 9

Divide by 2

d = 4.5

The sum  is then calculated using:

[tex]S_n = \frac n2 * (2a + (n - 1) * d)[/tex]

So, we have:

[tex]S_{15} = \frac {15}2 * (2*-2 + (15 - 1) * 4.5)[/tex]

Evaluate

[tex]S_{15} = 442.5[/tex]
