Simplify. (6+7i)(3−4i) Enter your answer, in standard form, in the box.
Answer: 46-3i
Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.
(6+7i)(3−4i)
18−24i+21i+28
(18+28)+(−24i+21i)
46-3i
- Hope this helps, have a blessed and wonderful day! :-)
In the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46).
What are complex numbers?
A complex number is a number of the form a + bi, where [a] and [b] are real numbers and [i] is equal to [tex]\sqrt{-1}[/tex].
Given is the following complex expression -
(6+7i)(3−4i)
We have -
(6 + 7i)(3 − 4i)
On expanding, we get -
6(3 - 4i) + 7i(3 - 4i)
18 - 24i + 21i - 28i²
18 - 3i - 28i²
18 - 3i - 28 (-1)
18 - 3i + 28
46 - 3i
- 3i + 46
Therefore, in the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46)

a trader silds 5 mobiles for Rs 35840and had profit of 12 %. find the cist of price of each mobile
Answer:
[tex]\huge{\boxed{\sf{ 6400 }}}[/tex]
Step-by-step explanation:
Correction:
A trader sells 5 mobiles for Rs 35840 and had profit of 12% . Find the cost price of each mobile.
Solution:
Selling price of 5 mobiles = Rs 35840
Now, we have to find the selling price of 1 mobile. So, for the cost of 1 mobile , the cost of 5 mobiles is divided by 5.
i.e [tex]\frac{35840}{5} =[/tex] Rs [tex]7168[/tex]
We have,
Cost of 1 mobile = Rs 7168
Profit % = 12 %
Finding the cost price of each mobile :
[tex]\boxed{\sf{ CP = \frac{SP * 100}{100 + Profit percent}}}[/tex]
[tex]CP = \frac{7168 * 100}{100 + 12}[/tex]
[tex]CP = \frac{716800}{112}[/tex]
[tex]CP =[/tex] Rs [tex]6400[/tex]

Alberto wants to keep their favorite tree from being uprooted by heavy winds. They plan to tie 3 sections of rope to a band on the trunk of the tree, 5 feet above the ground. They will tie each section of the rope to a stake in the ground 12 feet out from the base of the tree. How much rope will he need altogether?
Answer:
39 ft
Step-by-step explanation:
Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.
Pythagorean theorem: [tex]a^{2} +b^{2} = c^{2}[/tex] .... which a and b are the two sides while x is the diagonal.
[tex]5^{2} +12^{2} = x^{2}[/tex]
[tex]25 + 144 = x^{2}[/tex]
[tex]169 = x^{2}[/tex] ... now we square root both sides
[tex]13 = x[/tex]
Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.
13 * 3 = 39 ft

What is a numerical expression?A numerical expression is in the form of variables and constants separated by the operation of addition and subtraction. We can also form numerical expressions from statements.
Given an expression in variable h which is 8.5(4+3h)-h.
First, we'll apply distributive law to get rid of the bracket and separate the different terms. There are two more laws they are associative law and commutative law.
Distributive law state that a(b+c) = ab + bc.

The drama club is selling tickets to their play to raise money for the
show's expenses. Each student ticket sells for $6 and each adult ticket
sells for $11. The auditorium can hold at most 100 people. The drama
club must make no less than $770 from ticket sales to cover the show's
costs. If x represents the number of student tickets sold and y
represents the number of adult tickets sold, write and solve a system of
inequalities graphically and determine one possible solution.
Answer:
Student tickets sold 66
Adult tickets sold 34
Step-by-step explanation:
x=6. y=11
x+y=100. Multiply by -6
6x+11y=770 Then combine terms
5y=170 Divide 5 on both sides
y=34 Then do 100-34
x=66
This is the solution for the club to not earn anything but able to cover the fees.
The inequality form can be written as,
total revenue=66x+34y in this case total revenue=0

How many points need to be removed from this graph so that will be a function?
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The answer is you have to remove 4 points.
There is 6 points in all and for a function it only needs two points to become a function. A function needs to be a that line that passes the vertical line test. For example: A circle is not a function because when you perform the vertical line test you'll see that many points share a common x-value and a function needs only one output in every input.
1. Find the TRUE statement.
A. A graph will always eventually touch an asymptote.
B. If a graph has a vertical asymptote, it cannot have a horizontal asymptote.
C. If there is an asymptote at x = 0, then x can never equal 0.
D. A graph will get further and further from its asymptote.

Answer:
x = 2
Step-by-step explanation:
Is it -1/2 or just 1/2 I'll just answer both
x = 4
So -1/2 of x or -1/2 of 4 is -2
And 1/2 of 4 is 2.
So the answer is most likely 2
and is probably point z
4/(-1/2) = -2
4/(1/2) = 2

be used to find out how many weeks it will
take for them to save for the video game?
52-[(8 + 2) - (10 + 3)]

d. 52 + [(8 + 2) + (10 + 3)1
a.
Answer:
52/[(8 - 2) + (10 - 3)]
Step-by-step explanation:
Jeff earns $8 and spends $2 each week.
Each week he keeps (8 - 2).
Joe earns $10 and spends $ each week.
Each week he keeps (10 - 3).
The total amount they keep each week is
(8 - 2) + (10 - 3).
If you divide the cost of the game by the amount they keep each week, you get the number of weeks.
Answer: 52/[(8 - 2) + (10 - 3)]
