Mathematics

The light's coverage area is given mathematically as i.e. Area=\pi d^{2}

Given that a lighthouse casts a revolving beam of light as far as they peir and asked the area is covered.

The revolving beam of light covers the whole space i.e entirely 360°

I.e. it forms a circle-like region

Area of circle = \pi r^{2}{ where r is the radius of circle}

Let's assume the distance traveled by light as "d"

as it forms a circular region, it forms a circle of radius "d"

Mathematical connection i.e. area of the region

⇒area of circular region=\pi d^{2} {where d is the radius of region}

Answer:

La respuesta correcta es la opción d) 5 a 1.

Step-by-step explanation:

Para calcular la relación entre los ingresos de Mary en 2019 (I_{2019}) con respecto a sus ingresos en 2018 (I_{2018}), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:

I_{2019} = 20\% \: I_{2018}      

I_{2019} = \frac{20}{100}I_{2018}      

\frac{100}{20}I_{2019} = I_{2018}        

5I_{2019} = I_{2018}                  

Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

Espero que te sea de utilidad!

Helena has taken out a $9,300 unsubsidized Stafford loan to pay for her college education. She plans to graduate in four years.
kherson [118]
The effective annual interest rate is:
i = (1 + 0.064/12)^12 - 1 = 0.066
In year 1: the interest is $613.80 (multiple $9300 by 0.066)
In year 2: the interest is $654.31 (add interest from year 1 to $9300 and multiply by 0.066)
In year 3: the interest is $656.98 (do the same as year 2)
In year 4: the interest is $657.16

The total interest is: $2582.25
The present worth of this amount is:
P = 2582.23 / (1 + 0.066)^4 = $1999.72

The answer is $1999.72.

Evaluate 32 + 12 = ( 6 – 3) x 8.​
Brrunno [24]

Hello there!

(Equation #1) 32 + 12 = 44

(Equation #2) 6 - 3 = 3, 3 x 8 = 24

These both equations don't have the same answer, even though it says that they are equal with each other, if you could correct these these 2 equations I am willing to answer again.

Hope this helped!!
