A ring-shaped region is shown below. Its inner radius is 19 m, and its outer radius is 24 m. Find the area of the shaded region. Use 3.14 for . Do not round your answer.

Given:

The quadratic equation is :

[tex]16x^2-20x-6=0[/tex]

To find:

The quadratic formula for the given equation after substituting the values.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]16x^2-20x-6=0[/tex]

In this equation, [tex]a=16,b=-20,c=-6[/tex].

Substituting [tex]a=16,b=-20,c=-6[/tex] in the above formula, we get

[tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex]

Therefore, the required quadratic formula for the given equation after substituting the values is [tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex].

Answer:

m<A=97

m<B=97

Step-by-step explanation:

m<A=m<B

Congruent angles and they are vertical angles. The other two are also the same because the angles given have the same degrees.

m<A is supplementary to 83 degrees

Supplementary angles are two angles that sum up to 180 degrees.

180-83=97

97 degrees is the answer for each missing angles.

The fraction of the circle measured by a sector which subtends an angle; 45° is; 1/8 (one-eighth).

It has been established from circle geometry that the angle subtended at a point is 360°.

In essence, a sector which measures 45° is only 1/8 of the circle.

Answer:

Step-by-step explanation:

the area of a parallelogram is the same as a rectangle, well, uses the same formula. therefore it uses base × height.

for this equation we need to do 7.1 × 11.4

7.1 × 11.4 = 80.94

if you need to round the number to a whole number, it will be 81 because the first decimal digit is the number 9, and any decimal number 5 or up rounds up to the next number :D

good luck :)

Answer:

The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.

Step-by-step explanation:

According to this statement, we have a mixture with [tex]3.7\times 10^{-6}[/tex] grams of carbon powder and [tex]92\times 10^{-6}[/tex] grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:

[tex]\Delta m = 92\times 10^{-6}\,g \,-\,3.7\times 10^{-6}\,g[/tex]

[tex]\Delta m = 88.3\times 10^{-6}\,g[/tex]

The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.

Okay so rounding is simple

If the place digits before the digit your rounding to is 1-4 then just everything stays the same. If its 5 or above then you round the number up and put everything else into 0s.

Answer:

Step-by-step explanation:

f(0) = -2

f(1) = 3*(f(1 - 1)) -  2*1

f(1) = 3(-2) - 2

f(1) = - 6 - 2

f(1) = - 8

f(2) = 3*(f(1)) - 2*2

f(2) = 3*(-8) - 4

f(2) = -24 - 4

f(2) = - 28

f(3) = 3*(f(2)) - 2*3

f(3) = 3*-28 - 6

f(3) = -84-6

f(3) = - 90

f(4) = 3*f(3) - 2 * 4

f(4) = 3*-90 - 8

f(4) = -270 - 8

f(4) = -278

Step-by-step explanation:

área del parque

A=Pi . R^2

A=Pi (700m^2)

A=3.1416 x 490000m^2

A= 1539380.4 m ^2

área de la fuente

a= Pi. r^2

a=Pi (5cm^2)

a=3.1416 x 25cm^2

a= 78.54 cm^2

Luego lo que hacemos que al area grande le restamos la pequeña.

pero antes que nada convertiremos los metros a centimetros.

A= 1539380.4 m^2

1539380.4 m^2 (100cm/1m)

eliminaras los metros y te quedara asi

1539380.4  ( 100 cm/ 1)

153,938,040 cm^2

luego restamos A-a

153,938,040 cm^2 -  78.54cm^2

Answer:

175cm3

Step-by-step explanation:

How to find the volume

In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width, and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.

Multiply 25cm2 and 7cm

Therefore, the answer is 175cm3

Step-by-step explanation:

Set up synthetic division, starting with x - 1 as the divisor, and then (from that) 1:

1     /    1   0    0    -1               The coefficients of x^2 and x are zero here.

               1     1      1

     --------------------------

         1     1      1      0              

Since the remainder is zero, 1 is a root and x - 1 is a factor of the original

x^3 - 1 = 0.
