Answer:

Step-by-step explanation:

The exponential function for half-life problems is easily written using 1/2 as the base of the exponent.

  present value = (initial value) × (1/2)^(t/(half-life))

Then the amount (a) remaining after t days is ...

  a(t) = 487 × (1/2)^(t/36)

__

After 5 days, the amount remaining is ...

  a(5) = 487×(1/2)^(5/36) ≈ 442.302 kg

_____

Some folks like their exponential function to be written using e as the base for the exponent. Here, that would be ...

  a(t) = 487·e^(-0.019254t)

where the constant in the exponent is -ln(2)/36.

Answer:

$9398.50

Step-by-step explanation:

Given

[tex]\$1 = 106.40\ ALL[/tex]

Required

Equivalent of 1,000,000 ALL

We have:

[tex]\$1 = 106.40\ ALL[/tex]

and

[tex]\$x = 1000000\ ALL[/tex]

Cross Multiply

[tex]x * 106.40 = 1 * 1000000[/tex]

[tex]106.40x = 1000000[/tex]

Solve for x

[tex]x = 1000000/106.4[/tex]

[tex]x = \$9398.50[/tex] -- Approximated

Answer:

Step-by-step explanation:

The rule is that the exterior angle (ACD) is equal to the sum of the remote interior angles (the two marked angles on the right).

You are expected to use this relation to write and solve an equation.

  exterior angle = angle D + angle B

  (2x +16) = 58 + (x+12)

  2x +16 = x +70

  x + 16 = 70

  x = 54

Then angle ACD is ...

  angle ACD = (2x +16)° = (2·54 +16)°

  angle ACD = 124°

Answer: 15.6

Step-by-step explanation: k/13 = 6/5 = 15.6

Answer:

6/4y - 12 = 1/2y -4

3/2y -12 = 1/2y - 4

-1/2y          -1/2y

2/2y - 12 = -4           (2/2 = 1)

y - 12 = -4

+12      +12

y = 8

Step-by-step explanation:

Answer: 2х+5y=25=  Slope = -0.800/2.000 = -0.400

 x-intercept = 25/2 = 12.50000

 y-intercept = 25/5 = 5

so slope form =0,400

x intercept form = 12.50000

y intercept =5

and the answer to 2x+3y=-1=  Slope = 1.333/2.000 = 0.667

 x-intercept = 1/2 = 0.50000

 y-intercept = -1/3 = -0.33333

Step-by-step explanation:  an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2x+5y-25  = 0 and calculate its properties

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

 y-intercept = 25/5  =  5

When y = 0 the value of x is 25/2 Our line therefore "cuts" the x axis at x=12.50000

 x-intercept = 25/2  = 12.50000

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 4.200. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 4.200 - 5.000 = -0.800 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -0.800/2.000 = -0.400  

Geometric figure: Straight Line

 Slope = -0.800/2.000 = -0.400

 x-intercept = 25/2 = 12.50000

 y-intercept = 25/5 = 5

Answer:

- Opposite angles are congruent (equal).  

- Parallelograms have 4 sides

- Opposites sides are parallel and equal in length.

Step-by-step explanation:

A parallelogram is a quadrilateral and since quadrilaterals are fur sided figures, hence parallelograms are also four sided figures.

A parallelogram has its opposite side equal and parallel to each other with a slanting edge at two of its sides. Since its opposite sides are equal hence its opposite angles are also equal.

Parallelogram cannot have more than four sides because they are quadrilateral. Find the diagram of a parallelogram in the attached figure.

It can be seen from the attached figure that AB//CD and AD//BC

Answer:

y = -4x -16

Step-by-step explanation:

Line perpendicular have the slope = -1/m

Substitute the values,

8 = (-4)(-6) + c

8 = 24 + c

c = -16

Thus, the equation of the perpendicular line is y = -4x-16

Answer:

1/3x=14

answer for x is 42

Step-by-step explanation:

x represents the original number and 1/3 of the number equals 14. So 1/3x=14

So therefore 1/3x=14 which x = 42 in case if you were wondering.

Answer:

14cm and 22cm

Step-by-step explanation:

Given parameters:

Perimeter of rectangle  = 72cm

Ratio of length to width  = 7: 11

Unknown:

Length and width of the rectangle  = ?

Solution:

Since the ratio of length to width is 7: 11,

  if the length is 7x , width = 11x

 The perimeter of a rectangle can be obtained using

Perimeter = 2(L + W)

  Insert the parameters and solve;

          72  = 2(7x + 11x )

          72 = 2(18x)

           x  = [tex]\frac{72}{36}[/tex]  = 2

The length = 7x  = 7x2 = 14cm

        width  = 11x = 11 x 2 = 22cm
