Identify the imaginary part of this complex number:

Answers
Answer:
-7/2i
Step-by-step explanation:
The imaginary part of the complex number is -7/2.
What is complex form?A complex number can be expressed in the polar form in addition to the rectangular form. Complex numbers are typically expressed as z = x + iy, where 'i' is a fictitious integer. Complex numbers are described as a union of argument and modulus in polar form, however.
We know a complex form,
a + bi, where the coefficient of 'i' is the imaginary part and the rest of the part is a real part
So,
[tex]\frac{1}{2} + (\frac{-7}{2} )i[/tex]
Compared to the standard form,
-7/2 is the imaginary part.
Therefore, -7/2 is the imaginary part.

Answers
Answer:
298
Step-by-step explanation:
given data
total friend = 4
total profit in the first month = 438
two months each friend profit = 184
solution
we consider here total profit second month is = x
so
profit second month = 184 × 4 - 438
x = 736 - 438
x = 298
so that here profit that car wash making the second month is 298
Multiply.

The product of mean 350
The sum of extremes 73
The sum of the mean is 53

Step-by-step explanation:
The product of mean is 350 is not true
Option B is the correct answer
The false statement is the product of mean 350.
What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
10:18=35:63
So, 10/18 = 35/63
Here 10 & 63 -Extremes
and, 18 & 35= mean
so, product of extreme= 10 x 63= 630
and, product of mean= 18 x 35 = 630
Also, sum of Extremes = 10 + 63 = 73
and, sum of mean = 18 + 35= 53
Hence, the product of mean 350 is not true.

Given f(x) then the derivative f'(x) is
f'(x) = lim( h tends to 0 ) [tex]\frac{f(x+h)-f(x)}{h}[/tex]
= lim( h to 0 )[tex]\frac{x+h+\frac{1}{x+h }-(x+\frac{1}{x} ) }{h}[/tex]
= lim(h to 0) [tex]\frac{x+h+\frac{1}{x+h}-x-\frac{1}{x} }{h}[/tex]
= (lim(h to 0) [tex]\frac{h+\frac{1}{x+h}-\frac{1}{x} }{h}[/tex]
= lim( h to 0 ) [tex]\frac{hx(x+h)+x-(x+h)}{hx(x+h)}[/tex]

Cancel the numerator/denominator of first fraction and h in the second

Answers
Step-by-step explanation:
f(x) = 2.5x - 10.5 and g(x) = 64(0.5)^x
When x = 2,
f(x) = 2.5(2) - 10.5 = -5.5,g(x) = 64 * 0.5^(2) = 16.When x = 3,
f(x) = 2.5(3) - 10.5 = -3,g(x) = 64 * 0.5^(3) = 8.When x = 4,
f(x) = 2.5(4) - 10.5 = -0.5,g(x) = 64 * 0.5^(4) = 4.When x = 5,
f(x) = 2.5(5) - 10.5 = 2,g(x) = 64 * 0.5^(5) = 2.When x = 6,
f(x) = 2.5(6) - 10.5 = 4.5,g(x) = 64 * 0.5^(6) = 1.Therefore we can see that f(x) = g(x) = 2 when x = 5.
Hence the solution is x = 5.

If you want to write it in more simple picture :

Answer:
[tex]\left(\frac{1}{4}m-2n\right)^2=\frac{m^2}{16}-mn+4n^2[/tex]
Step-by-step explanation:
Given the polynomial
[tex]\left(\frac{1}{4}m-2n\right)^2[/tex]
Expanding and simplifying
[tex]\left(\frac{1}{4}m-2n\right)^2[/tex]
as 1/4 = 4/m, so
[tex]=\left(\frac{m}{4}-2n\right)^2[/tex]
Apply perfect square formula: [tex]\left(a-b\right)^2=a^2-2ab+b^2[/tex]
[tex]=\left(\frac{m}{4}\right)^2-2\cdot \frac{m}{4}\cdot \:2n+\left(2n\right)^2[/tex]
simplifying
[tex]=\frac{m^2}{4^2}-mn+2^2n^2[/tex]
[tex]=\frac{m^2}{16}-mn+4n^2[/tex]
