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

Answers

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.

What is a complex number?

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.

. Evaluate the following: |15 - 47] + 9 - (-2)(-4) - 17|

Answers

Answer:

Grace and her brother need $400 to go to band camp. Their parents have agreed
to help them earn money by paying them $25 each time they mow the lawn
and $10 for each hour they babysit their younger brother. They will have to do a
combination of both chores to earn the money.
Select the equation that represents the number of lawns they can mow, m, and
hours they can babysit, b, to earn $400.
M. 10m + 25b = 400

You need to find the two numbers that add to -4 and multiply to 3
Those are-3 and 1-
(X-3) (x-1)
X=3 X=1

Now let’s check to make sure that when plugged in the answer is over 0.
3^2+3(3)-4=
9+9-4=14
14 is greater than 0
✅

1^2+3(1)-4=
1+3-4=0
0 is not greater than 0

So x is 3

The angle of elevation of an electricity pole from a point 8 metres from its base is 52.7 degrees. What is the height of the pole?

Answers

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

Match each expression to its exponential form.

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

"You purchase a vintage car for $140,000 and it appreciates (i.E. Increases in value) by 4% annually. How much will the car be worth in 10 years?"

Answers

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

Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original. Halla la suma de cifras del producto original

Answers

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.

Step-by-step explanation:

A rake was marked up 25% from an original cost of $8.80. Last Friday, Dean bought the rake and paid an additional 3% in sales tax. What was his total cost?

Answers

Answer:

$11.33

Step-by-step explanation:

First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33

The total cost of the rake is $11.33.

What is the sales tax?

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Given that, a rake was marked up 25% from an original cost of $8.80.

25% of the original cost of $8.80 is

0.25×8.80 =$2.2

So the marked up price was 8.80+2.20

= $11

He then paid an additional 3% in sales tax, that is

11 + 0.03×11 = $11.33

Therefore, the total cost of the rake is $11.33.
