Sin * (x - y) , if sin x = 8/17 cos y = 12/37

abruzzese [7]

Answer:

-429/629

Step-by-step explanation:

Use angle difference formula:

sin(x − y) = sin x cos y − sin y cos x

Assuming x and y are in the first quadrant:

sin(x − y) = sin x cos y − √(1 − cos²y)√(1 − sin²x)

Plugging in values:

sin(x − y) = (8/17) (12/37) − √(1 − (12/37)²)√(1 − (8/17)²)

sin(x − y) = (8/17) (12/37) − (35/37)(15/17)

sin(x − y) = -429/629

Una compañía suministra electricidad. Cobra $100 mensuales fijos más 15 centavos por kilowatt hora. En los primeros 400 kilowatt

sweet [91]

Answer:

La función resultante es una función a trozos:

$C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}$

Step-by-step explanation:

El coste total de la electricidad suministrada ( $C_{T}$ ), medida en pesos, es la suma del coste fijo ( $C_{F}$ ) y el coste variable ( $C_{V}$ ), medidas en pesos.

$C_{T} = C_{F}+C_{V}$ (1)

Ahora, tenemos que el coste fijo es $ 100 mensuales, así:

$C_{F} = \$ \,100$ (2)

Y el coste variable considera que se cobra 15 centavos por kilowatt-hora para los primeros 400 kilowatts-hora y 12 centavos por kilowatt-hora para cada kilowatt-hora que pase de 400 kilowatts-hora en el mes:

(i) Menos o igual que 400 kilowatts-hora:

$C_{V} = 0.15\cdot x$ (3)

Donde $x$ es la electricidad suministrada en kilowatts-hora.

(ii) Mayor que 400 kilowatts-hora:

$C_{V} = 0.15\cdot (400)+0.12\cdot (x-400)$

$C_{V} = 12+0.12\cdot x$

La función resultante es una función a trozos:

$C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}$

How many solutions does the following equation have?<br> 13x - 8 + 7x – 2 = 11+ 6x -- 14x – 5

Alona [7]

STEP BY STEP:

13x - 8 + 7x – 2 = 11+ 6x -- 14x – 5

Combine like terms

20x-8-2 = 20x+11-5

20x-10 = 20x+6

Subtract with -20x on both sides and the result is:

$-10\neq 6$

The answer is NO SOLUTION

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and ite

mart [117]

Answer:

12.5%

Step-by-step explanation:

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

The formula for Percentage Decrease =

Decrease in price/ Initial price × 100

Decrease in price = $10

Initial price = $80

Hence:

$10/$80 × 100

= 12.5%

Hence, the percentage the price will be decreased by before tax is 12.5%
