The slope of the given equation of the straight line is - 5/4.

We know that the direction of a line is defined by its slope. The slope is calculated by dividing the difference between the y-coordinates of two points on a line by the difference between their x-coordinates.

Here the equation of the line is

y = - (5/4)x - 1.

At x = 0, y = -(5/4) × 0 - 1 = -1

and at x = 4, y = -(5/4) × 4 - 1 = - 5 - 1 = -6

Now the slope = (-6 - (-1))/(4 - 0) = (-6 + 1)/4 = - 5/4

Therefore the slope of the given equation of the straight line is - 5/4.

Answer:

[tex]-2\sqrt{3} +2\sqrt{15}[/tex]

Step-by-step explanation:

When we simplify this equation, we have to multiply the numbers outside the parenthesis with the the numbers inside the parenthesis. In this equation, we have to multiply [tex]\sqrt{12}[/tex] by [tex]-1[/tex] , getting the answer of [tex]-\sqrt{12}[/tex], which can be further simplified into [tex]-2\sqrt{3}[/tex]. Next, looking at [tex]\sqrt{12}[/tex] × [tex]\sqrt{5}[/tex], we get [tex]\sqrt{60}[/tex], which can also be simplified further into [tex]2\sqrt{15}[/tex]. Now, adding up these two numbers get [tex]-2\sqrt{3} +2\sqrt{15}[/tex].

Horizontal and Vertical translations can transform f(x) to g(x).                                                                                                                                                                                                            

Equations to transform f(x) to g(x) are: g(x) = f(x) + k, and g(x) = f(x + k).

In vertical translation k = 18, and horizontal translation k = 6.

Equations of the two st. lines

Select two points on the line f(x) viz. (1,2), (2,5).

The equation of the line f(x) is

[tex]\frac{y-2}{x-1} = \frac{5-2}{2-1} \Rightarrow \mathbf{y=3x-1}.[/tex]

Select two points on the line g(x) viz. (-5,2), (-4,5).

The equation of the line g(x) is

[tex]\frac{y-2}{x+5} = \frac{5-2}{-4+5} \Rightarrow \mathbf{y=3x+17}.[/tex]

Ways to transform

The two lines, f(x) and g(x), are parallel to each other so their orientation w.r.t. each other is not changed. f(x), thus, can be translated to obtain g(x).

The translation of f(x) can be done in two ways: Vertical translation, and Horizontal translation.

Horizontal translation

f(x) can be translated horizontally to obtain g(x) by the relation of type g(x) = f(x + k).

Using the above relation for the two lines,

3x + 17 = 3(x + k) -1  ⇒  k = 6.

The horizontal translation relation is g(x) = f(x + 6).

Vertical translation

Vertical translation can be done with the relation g(x) = f(x) + k.

Using the above relation for the two lines,

3x + 17 = 3x - 1 + k  ⇒  k = 18.

The vertical translation relation is g(x) = f(x) + 18.

The two transformation relations are: g(x) = f(x + 6), and g(x) = f(x) + 18.

The weight of a cubic foot of stone is 5/16 the weight of a cubic foot of iron.

Answer:

  -1/2

Step-by-step explanation:

Zeros of a polynomial function are its x-intercepts, the values of x that make the polynomial zero. Each zero x=p corresponds to a linear factor (x-p) of the polynomial.

A monic polynomial is one that has a leading coefficient of 1. For a monic polynomial of degree n, the coefficient of the term of degree n-1 is the opposite of the sum of all of the zeros. The constant term of any odd-degree monic polynomial is the opposite of the product of the zeros.

The given polynomial can be made monic by dividing by its leading coefficient:

  (2x^3 -x^2 -5x -2)/2 = x^3 -(1/2)x^2 -(5/2)x -1

The given polynomial has degree 3, so we're interested in the coefficient of the x^2 term. That coefficient is -1/2, so the sum of zeros will be ...

  sum of zeros = -(-1/2) = 1/2

If z represents the third zero, then we have the sum ...

  1/2 = -1 +2 +z

  z = -1/2 . . . . . . subtract 1 from both sides

The third zero is -1/2.

The given polynomial is of odd degree, so the product of the zeros is the opposite of the constant.

  (-1)(2)(z) = -(-1)

  z = 1/(-2) = -1/2 . . . . . divide by the coefficient of z

The third zero is -1/2.

Of course, a graph will show all of the (real) zeros. The attached graph from a graphing calculator shows the third zero is -1/2.

The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.

The second arc should be centered at C because as it crosses passing through Line C, it is seen that it was not touching or intersecting AB and so one can say that it is parallel to it.

Looking at the other lines, we will see that they are all touching AB and are not running parallel to it.

Using 3 different methods, we can find that YZ = 25m

The complete image of a triangle is attached with the answer below.

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

For a given triangle rectangle with a known angle θ and a hypotenuse H, we can write the trigonometric relations

sin(θ) = (opposite cathetus)/H

cos(θ) =(adjacent cathetus)/H

tan(θ) =(opposite cathetus)/(adjacent cathetus)

Now, in the given image we can see that:

θ = 30°

H = 50m

XY = adjacent cathetus

YZ = opposite cathetus.

We want to find YZ, so with the known things, we can use the first relation:

Sin 30 = YZ / 50

YZ = 50 x Sin30 = 25 meters

Now let's try another way.

We know that the sum of the internal angles of a triangle is always equal to 180°

In a triangle rectangle, we always have an angle equal to 90°.

Then the missing angle for our triangle can be computed from:

Z + 90° + 30° = 180°

Z = 180° - 90° - 30° = 60°

From this angle, the side YZ is the adjacent cathetus, then we can use the second trigonometric relation:

Cos 60 = YZ / 50

YZ = 50 x Cos 60 = 25 meters

Third way.

Whit the same angle we could find the side XY, the opposite cathetus, with:

Sin 60 = XY / 50

XY = 50Sin 60 = 43.3 meters

Now that we know one of the catheti, we can use the last trigonometric relation

tan 60 = XZ / YZ = 43.3 / YZ

YZ = 43.3 / tan 60 = 25 meters

f(a)= a³ +a

…………………………

(fog)(a)​ = f(g(a)​))

           = g(a)³ + g(a)

           = (a - 1)³ + (a - 1)

           = (a³ - 3a² + 3a - 1) + (a - 1)

           = a³ - 3a² + 3a - 1 + a - 1

           = a³ - 3a² + 3a + a - 1 - 1

           = a³ - 3a² + 4a - 2

Second method :

(fog)(a)​ = f(g(a)​))

The perimeter is 48

Step-by-step explanation:

If the width is W

AT first , Length is 10 +w

According to the question,

[tex](w+8) (10+w+4) = 135\\(w+8) (w+14) = 135\\\\w^{2} + 14w + 8w + 112- 135 = 0\\\\ w^{2} + 22w - 23 = 0\\(w+23) (w-1) = 0\\\\w+ 23 = 0 w-1=0\\\\w= -13 or w = 1[/tex]

Expended width will be  w +8 = 1+8 = 9

Length is 10+w+4 = 15

So the perimeter is

= i2 x (9+15)

= 2x 24

= 48

The Solution to the problem of the rectangle is given below

For Part A:

For Part B

Meaning of Perimeter

The perimeter of any shape can be defined as the total sum of the sides of the shape.

For Part A

equation model= (14 + w) * (w +8) = 135

14w + 112 + 8w + [tex]w^{2}[/tex] = 135

[tex]w^{2}[/tex] + 22w - 23 = 0

solving the quadratic equation

w = -23 or 1

Answer:

5. c = 8pi cm

6. c = 18pi ft

7. c = 8.6pi in

8. c = 11/2pi m

Step-by-step explanation:

The circumference of a circle can be easily found using the formula: c = [tex]\pi[/tex]d, where the diameter is d.

Now you just plug your numbers into the formula!

5. c = pi x d

   c = 8pi cm

6. This one gives you the radius instead of the diameter. All you need to do now is to double the radius to find the diameter.

     9 ft x 2 = 18 ft

   Now, it follows the formula.

   c = pi x d

   c = 18pi ft

7. c = pi x d

   c = 8.6pi in

8. c = pi x d

   c = pi x 2(2 3/4m) - Note that this is a mixed fraction. To be able to multiply it, you need to convert it to an improper fraction.

Less complex:

Area of a triangle = 1/2 * b * h = 60

=> h = 120/b

In right triangle ABD

13² = h² + b² /4 ( by Pythagoras law)

=>169 = 120²/b² + b²/4

=>676 b² = 57600 + b^4

=> b^4 - 676 b² + 57600 = 0

=> b² = 676 +- √(676² - 4*57600) / 2

=> b²= 676 +- √(226576) /2

=> b² = (676 +- 476 )/2

=> b² = 1152/2 , 200 /2

=> b² = 576 , 100

=> b = 24, 10

So, Base = 24 cm or 10cm
