Answer:

7 + 11i

Step-by-step explanation:

Simplify: (2 +8i)-(-5 - 3i) = 2 + 8i + 5 + 3i  

Add real numbers to real numbers and imaginary to imaginary: 2 + 8i + 5 + 3i = 7 + 11i

A complex number can be shown as a pair of integers (a, b). The difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

A complex number can be shown as a pair of integers (a, b) forming a vector on an Argand diagram, which represents the complex plane.

The difference of the complex number can be done as following,

(2+8i)-(-5-3i)

= 2 + 8i + 5 + 3i

= 5+2 + 8i+3i

= 7 + 11i

Hence, the difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

Answer:

48

Step-by-step explanation:

Since there is an absolute value, the answer must be positive. Multiply 2 by 8 since two negatives equal a positive. So, |15-47 + 9 - 8 -17|. Then add and subtract to get the answer. -32 + 9 - 8 -17 = -48. |-48| = 48

Answer:

Future Value= $207,234.2

Step-by-step explanation:

Giving the following formula:

Initial value (PV)= $140,000

Appreciation rate (r)= 4% = 0.04

Number of years (n)= 10

To calculate the future value of the car after ten years, we need to use the following formula:

FV= PV*(1+i)^n

FV= 140,000*(1.04^10)

FV= $207,234.2

10^2 = 10 × 10

10^3 = 10 × 10 × 10 = 1000

10^4 = 10 × 10 × 10 × 10

Answer: 119.96

Step-by-step explanation:

Answer:

10.5m

Step-by-step explanation:

We solve the above question, using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = 52.7 °

Adjacent = 8 m

Opposite = x

Hence,

tan 52.7= x/8m

Cross Multiply

x = tan 52.7 × 8m

x = 10.501501092m

Approximately = 10.5 m

Therefore, the height of the pole = 10.5m

Answer:

D. 2^7

Step-by-step explanation:

Answer:

2^7

Step-by-step explanation:

When we multiply the same bases with exponents like 2^3*2^4 we can add the exponents and keep the base the same

2^7 would be the answer or you can simplify further to get 128

but they said simplify so 2^7 is the answer

If they said evaluate then our answer is 128

Answer:

That would be -2n - 1.

Answer:

-2n - 1

Step-by-step explanation:

You have to combine like term which would be 4n,n,and 7n.

Since n doesn't have a variable just add a one in front. So now the equation would be

1n+4n-7n That equation equals -2n

Now just add the remaining number

So that makes the answer -2n -1

Answer:

La suma de cifras del producto original es igual a 12.

Step-by-step explanation:

De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:

32x=y+54

Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:

y=23x

Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:

32x=23x+54

32x-23x=54

9x=54

x=54/9

x=6

Finalmente, puedes reemplazar el valor de x en y=23x:

y=23x

y=23*6

y=138

Suma de cifras: 1+3+8 = 12

De acuerdo a esto, la respuesta es que la suma de cifras es igual a 12.
