Select all the correct expressions in the table which expressions are equivalent to the given complex number 45+2i
The expressions are given below:
What is complex number?Complex numbers are numbers that consist of two parts — a real number and an imaginary number.
Given:
45+ 2i
9+4 i + 2( 4 + 7i)(1- 2i)
= 9 +4i + 2( 4 - 8i + 7i +14)
=9 + 4i + 36 - 2i
= 45 - 2i
and,

The function f given by f(x)=3x5−4x3−3x has a relative maximum at x?
Answer:
We have the function:
f(x) = 3*x^5 - 4*x^3 - 3*x
To find the maximum/minimums, we first need to look at the roots of the first derivative of f(x), this is:
f´(x) = 5*3*x^4 - 3*4*x^2 - 3
f´(x) = 15*x^4 - 12*x^2 - 3
We can do the change of variable:
u = x^2
Then we can rewrite:
f'(u) = 15*u^2 - 12*u - 3
This is a quadratic equation, the solutions will be obtained by the Bhaskara´s equation:
So the solutions are:
[tex]u = \frac{+12 +- \sqrt{(-12)^2 - 4*(-3)*15} }{2*15} = \frac{12 +- 18}{30}[/tex]
Then the two solutions are:
u = (12 + 18)/30 = 1
this leads to:
x^2 = 1, then we can have x = ± 1
the other solution is:
u = (12 - 18)/30 = -6/30 = -(1/5)
and x^2 = -(1/5), then:
x = ±√(1/5)*i
So those are the possible values for the minimum/maximums.
Now to see it, we need to look at the second derivative ad see iff:
f´´(x) > 0 then x is a minimum
f''(x) < 0, then x is a maximum.
We have that:
f´´(x) = 4*15*x^3 - 2*12*x
f´´(x) = 60*x^3 - 24*x
Notice that the two complex roots will lead to complex values of f(x), so these can be ignored here, then we have to try only with x = ± 1.
f´´(1) = 60*1^3 - 24*1 = 36
then x = 1 is a minimum.
f´´(-1) = 60*(-1)^3 -24*-1 = -36
then x = -1 is a maximum.
Then we can conclude that the relative maximum is at x = -1
The function f given by [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at
x = -1
The given function is:
[tex]f(x) = 3x^5-4x^3-3x[/tex]
Find the derivative of the function:
[tex]f'(x)=15x^4-12x^2-3[/tex]
Find the critical points by equation f'(x) to zero
[tex]15x^4-12x^2-3=0\\\\5x^4-4x^2-1=0[/tex]
By solving the equation above, the critical points are:
x = -1, x = 1
Find the second derivative of f(x)
[tex]f''(x)=60x^3-24x[/tex]
[tex]f''(-1)=60(-1)^3-24(-1)\\\\f''(-1)=-36[/tex]
Since f''(-1) < 0, x = -1 is a maximum point
[tex]f''(1)=60(1)^3-24(1)\\\\f''(1)=36[/tex]
Since f''(1) > 0, x = 1 is a minimum point
Therefore, the function [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at x = -1

y varies inversely as x. When x=10, y=20. Find y when x=50
Answer:
y=100
Step-by-step explanation:
You can solve this by comparing the ratio.
The first set is 10:20 or 1:2 when simplified.
This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.

Two triangles A B C and D F G. A B is 5 inches. B C is 6 inches. A C is 7 inches. D F is 15 inches. F G is 18 inches. Angle B is congruent to angle F.
I believe the answer is 5/7=15/DG.
Please, do correct me if the answer seems wrong, thank you.
The proportion which can be used to describe the value of DG is
15 x 7 = 5 x DG
What are similar triangles?
Two triangles are said to be similar if their sides are proportional and their angles are equal.
Given data ,
The two triangles are ΔABC and ΔDFG are similar
Length of AB = 5 inches
Length of BC = 6 inches
Length of AC = 7 inches
Length of DF = 15 inches
Length of FG = 18 inches
And , ∠B is congruent to ∠F
The two triangles are similar , so the ratio of
AB / DF = BC / FG = AC / DG
Therefore , 5 / 15 = 7 / DG
DG = 21 inches
Hence , the proportion used to find the value of DG is 15 x 7 = 5 x DG

Which statements are true about the ordered pair (7, 19) and the system of equations?
The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (7, 19) is a solution to the system because it makes both equations true.
Answer:
(7,19) is a solution for only the first equation (2x-y= -5), so it is not a solution to the systemmmm

It takes Sam 3 hours to rake leaves, but if Laura helps, it takes 2 hours. How long would it take Laura to rake the leaves on her own?
Answer:
6 hours
Step-by-step explanation:
Given that:
Time taken by Sam = 3 hours
Sam's rate = 1/3
Time taken : Sam + Laura = 2 hours
Sam's rate + Laura's rate = 1/2
Let time taken by Laura = x
1/3 + 1/x = 1/2
1/x = 1/2 - 1/3
1/x = (3 - 2) / 6
1/x = 1 /6
x = 6
Hencw, it will take 6 hours for Laura alone to rake leaves
