Tenemos precio de lista de $25 para el libro.

Si aplicamos un descuento del 25%, este descuento representa:

D=(\frac{25}{100})\cdot25=0.25\cdot25=6.25

Ahorramos $6.25.

El precio que pagamos el libro es $18.75.

P=L-D=25-6.25=18.75

A+B-C=3pi then find sinA+sinB-sinC
steposvetlana [31]
The answer:
the full question is as follow:

if A+B-C=3pi, then find sinA+sinB-sinC

first, the main formula of sine and cosine are:
sinC = 2sin(C/2)cos(C/2)
sinA +sinB = 2sin[(A+B)/2]cos[(A-B)/2]

therefore: 
 sinA+sinB-sinC = 2sin[(A+B)/2]cos[(A-B)/2] - 2sin(C/2)cos(C/2)

sin[(A+B)/2] = cos(C/2)
2sin(C/2)cos(C/2) = cos[(A+B)/2
and 
A+B-C=3 pi implies A+B =3 pi + C, so 
cos[(A+B)/2] = cos [3 pi/2  + C/2]
and  with the equivalence cos (3Pi/2  + X) = sinX

sinA+sinB-sinC =  cos(C/2)+ sin(C/2)

Find two consecutive odd integers such that the square of the first added to 3 times the second, is 24. Part a: Define the varia
fgiga [73]

Given:

There are two consecutive odd integers such that the square of the first added to 3 times the second, is 24.

To find:

Part a: Define the variables.

Part b: Set up an equations that can be solved to find the integers.

Part c: Find the integers.

Solution:

Part a:

Let x be the first odd integers. Then next consecutive odd integer is x+2, because the difference between two consecutive odd integers is 2.

Part b:

Square of first odd integers = x^2

Three times of second odd integers = 3(x+2)

It is given that the sum of square of first odd integers and three times of second odd integers is 24. So, the required equation is:

x^2+3(x+2)=24

Part c:

The equation is:

x^2+3(x+2)=24

It can be written as:

x^2+3x+6=24

x^2+3x+6-24=0

x^2+3x-18=0

Splitting the middle term, we get

x^2+6x-3x-18=0

x(x+6)-3(x+6)=0

(x-3)(x+6)=0

x=3,-6

-6 is not an odd integer, so x=3 and the first odd integer is 3.

Second odd integer = x+2

                                  = 3+2

                                  = 5

Therefore, the two consecutive odd integers are 3 and 5.
