Find the values of x and y for 3x + 2iy = 6 + 10i

Mathematics
2 answers:
Evgen [1.6K]3 years ago

In this question, the given equation is

3x + 2yi = 6 + 10i

To solve for x and y, we have to compare both sides, and on doing so, we will get

3x=6, 2y=10

Now we need to isolate x and y, by getting rid of 3 and 2 , that is with x and y respectively .

x=2, y=5

So for the given equation to be true, the values of x and y are 2 and 5 respectively .

Answer:  The required values are x = 2  and  y = 5.

Step-by-step explanation:  We are given to find the values of x and y from the following equation :

3x+2iy=6+10i~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the values of x and y from the given equation, we need to compare the real and imaginary parts of the equation.

After comparing the real and imaginary parts from both sides of equation (i), we get

3x=6\\\\\Rightarrow x=\dfrac{6}{3}\\\\\Rightarrow x=2

and

2y=10\\\\\Rightarrow y=\dfrac{10}{2}\\\\\Rightarrow y=5.

Thus, the required values are x = 2  and  y = 5.

What is the surface area of the regular pyramid given below ?
Levart [38]

Answer:

Option C 207\ units^{2}

Step-by-step explanation:

we know that

the surface area of a pyramid is equal to

SA=B+LA

where

B is the area of the base

LA is the lateral area

The area of the base B is

B=9*9=81\ units^{2}

The lateral area is equal to

LA=4*(1/2)(9*7)=126\ units^{2}

the surface area is equal to

SA=81+126=207\ units^{2}

I WILL MAKE YOU BRAINIST
nekit [7.7K]

Answer:

234

Step-by-step explanation:

We want to find the summation from n = 2 to n = 10 of the equation -4 + 5n.

We can use the summation formula:

S=\frac{(a_1+a_n)*n}{2}, where a1 is the first term, a_n is the last term, and n is the number of terms

Here, we can say the first term occurs when n = 2:

-4 + 5n

-4 + 5 * 2 = -4 + 10 = 6

The last term will be when n = 10:

-4 + 5n

-4 + 5 * 10 = -4 + 50 = 46

The number of terms is just 10 - 2 + 1 = 9 terms.

Substitute these in:

S=\frac{(a_1+a_n)*n}{2}

S=\frac{(6+46)*9}{2}=\frac{468}{2} =234

Thus, the answer is 234.
