Please help me with this problem!!!!!
Irina18 [472]

Answer:

y + 20 = 9(x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 20) and (x₂, y₂ ) = (9, 79)

m = \frac{79+20}{9+2} = \frac{99}{11} = 9

Using (a, b) = (- 2, - 20), then

y - (- 20) = 9(x - (- 2)), that is

y + 20 = 9(x + 2)

Someone please help I cannot figure this out PLEASE

Let the side of the square = a units,   the area of the square = a^2 sq units

Area of the 4 semicircles  = area of 2 circles = 2 pi r^2 =  2pi (1/2 a)^2
  =   pi a^2 / 2

Probability of a point in the unshaded square being picked)  = area square / area of the total figure  = a^2  / (a^2 * pi/2)   = 1 / pi/2 = 2 /pi

which is approximately  65%

A hospital stores one type of medicine in 2-decagram
Aleks04 [339]

Answer:

There are 20,000 milligrams in one 2-decagram container . Thus option D is correct.

Step-by-step explanation:

The given information is one type of medicine in 2 decagram container.

Here, we know ,

      1 decagram = 10 grams

and, 1000 milligrams =1 gram

now -: 2 decagram = 2 × 10grams   {since 1decagarm = 10 grams }

                               = 20 grams .

then ,                   = 20× 1000milligrams {since 1 gram = 1000 milligrams}

                           =20,000 milligrams .

Hence, the correct option is D that is 20,000 milligrams .
