This is urgent will give brainliest!
Answer:
[tex] = 2 + \sqrt{3} i - (9 + 9 \sqrt{3} i) \\ = (2 - 9) + ( \sqrt{3} - 9 \sqrt{3} )i \\ = - 7 + (1 - 9) \sqrt{3} i \\ = - 7 - 8 \sqrt{3} i[/tex]
The required simplification of z2-z1 = -7-8sqrt(3)i.
z1=9+9sqrt(3)i
z2=2+sqrt(3)i
z2-z1 to be determined.
A complex number is defined as the sum of a real and imaginary numbers.
Here,
[tex]z_1=9+9\sqrt(3)i\\z_2=2+\sqrt(3)i\\\\z_2-z_1 = 2+\sqrt(3)i-(9+9\sqrt3i\\z_2-z_1 = 2-9+\sqrt(3)i-9\sqrt3i\\z_2-z_1 = -7-8\sqrt(3)i[/tex]
Thus, the required simplification of z2-z1 = -7-8sqr(3)i.

A particle moves along the curve y = 5x^2 – 1 in such a way that the y value is decreasing at the rate of 2 units per second. At what rate is x changing when x = 1?
Decreasing one fifth unit/sec
Increasing one fifth unit/sec
Decreasing one tenth unit/sec
Increasing one tenth unit/sec
Answer:
The correct option is;
Increasing one fifth unit/sec
Step-by-step explanation:
The equation that gives the curve of the particle of the particle is y = 5·x² - 1
The rate of decrease of the y value dy/dt = 2 units per second
We have;
dy/dx = dy/dt × dt/dx
dy/dx = 10·x
dy/dt = 2 units/sec
dt/dx = (dy/dx)/(dy/dt)
dx/dt = dy/dt/(dy/dx) = 2 unit/sec/(10·x)
When x = 1
dx/dt = 2/(10·x) = 2 unit/sec/(10 × 1) = 1/5 unit/sec
dx/dt = 1/5 unit/sec
Therefore, x is increasing one fifth unit/sec.

during a test of a totalizing flow meter, the water depth rose 15 inches in a tank 18 inches in diameter. What was the total flow in gallons
Answer:
The total flow in gallons is approximately 16.524 gallons
Step-by-step explanation:
The given diameter of the tank, D = 18 inches
The amount by which the water depth rose, Δh = 15 inches
The quantity being measured = The total flow = The change in volume of water in the tank
The change in the volume of the water in the tank, ΔV = (π × D²/4) × Δh
Substituting the known values, gives;
ΔV = (π × D²/4) × Δh = (π × (18 in.)²/4) × (15 in.) ≈ 3817.035 in.³
1 gallon = 231 in.³
ΔV ≈ 3817.035 in.³ = 3817.035 in.³ × 1 gallon/(231 in.³) ≈ 16.524 gallons
The change in the volume of the water in the tank, ΔV in gallons = The total flow in gallons ≈ 16.524 gallons.

What is a decimal number?A decimal number is a number that consists of a whole number and a fractional part separated by a point. For example – 3.5, 6.79, 78.32, etc.
Given here: Given the proper fraction as 1/4
To convert a fraction to a decimal, we'll just divide the numerator...by the denominator.
Thus 1/4=0.25
1/2=0.5
Now the difference between each of the given points is 1/2-1/4=0.25
And 1/4-0=0.25
Also 1-1/4=0.75
Thus the point 1/4 is equidistant from the points 0 and 1/2 but is 0.75 units away from 1
Hence, The given point 1/4 lie closer to 0& 1/2 than 1

The diagram shows the number of quarts of blood the human heart pumps per minute. A drawing shows an anatomy of human heart. Label reads: Pumps 5 quarts of blood per minute. a. How many quarts of blood does the human heart pump per hour? quarts per hour Question 2 b. How many liters of blood does the human heart pump per minute? liters per minute
The unitary method is used to find the unit value of any quantity.
(a)The human heart pumps 300 quarts/hour.
(b) The human heart pumps 4.730 liters/minute.
What is Unitary method ?In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
Reading on the label is 5quarts/min.
Since, 60 min = 1 hour
Use unitary method to get,
1 min = 1 / 60 hour.
Therefore, pumping of blood in quarts/hour = 5 / (1 / 60)
= 5 × 60
= 300
Since, 1 quart = 0.946 liter
The pumping of blood in liter/minute = 0.946 × 5
= 4.730.
Hence, the human heart pumps 300 quarts of blood per hour and 4.730 liter of blood per minute.

Consider the function f(x) = |x|. Let g(x) = |–4(x – 7)|.
Which shows the graphs of f(x) and g(x)?
A.) On a coordinate plane, y = g (x) opens up and goes through (negative 3, 4), has a vertex at (negative 2, 0) and goes through (0, 7). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).
B.) On a coordinate plane, y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).
C.) On a coordinate plane, y = g (x) opens down and goes through (6, negative 4), has a vertex at (7, 0) and goes through (8, negative 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).
D.) On a coordinate plane, y = g (x) opens up and goes through (negative 8, 4), has a vertex at (negative 7, 0) and goes through (negative 6, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).

The graph of absolute value function f(x) and g(x) are:
On a coordinate plane, y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).
The correct answer is an option (B)
What is an absolute value function?"A function of the form f(t) = |t| ."
What is a graph of a function?"It is a set of points on the coordinate plane that follows given function."
For given question,
We have been given an absolute value function f(x) = |x|
and absolute value function g(x) = |-4(x - 7)|
The graph of f(x) = |x| is like a 'V', with its vertex at (0, 0).
Y = f (x) opens up and goes through (-4, 4), has a vertex at (0, 0), and goes through (4, 4)
Consider absolute value function, h(x) = |x - 7|
A function h(x) is the function f(x) is translated horizontally 7 units right.
The graph of h(x) = |x - 7| is like a 'V', with its vertex at (7, 0).
Now consider absolute value function g(x) = |-4(x - 7)|
A function g(x) is the function h(x) is compressed inside by factor 4.
So, the graph of y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4).
Therefore, the graph of absolute value function f(x) and g(x) are:
On a coordinate plane, y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).

Answer:
First Option {-2 , 0 , 2}
Step-by-step explanation:
A critical point occurs when the derivative is 0 or undefined.
The function in the question is undefined at x = 2 and at x = -2 because if we put x = 2 or x = -2 the denominator becomes 0 hence anything divided by 0 is undefined, and the derivative equals 0 at x = 0 so the critical points are
{-2 , 0 , 2}
Use the quotient rule to find the derivative of the function then equal it to zero
[tex]y=\frac{x^2-1}{x^2-4}\\\\\frac{dy}{dx}=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=2x^3-8x-2x^3+2x\\0=-6x\\x=0[/tex]

What point is on both lines y = {x +3 and y = x +1? (1 point)
Please help ASAP
Answer:
No point
Step-by-step explanation:
This is a trick question because if you break down the graphing equations to y=mx+b, you see that it is a linear graph, so it will have a straight line. For the first equations, y=x+3, you look at the original equations, y=mx+b. m=slope, b=x-intercept. Slope is rise/run (y/x) so the slope would be up one, over one (1/1=1). The x-intercept is 3 so its a straight line but it intercepts at 3. The next equation is the exact same thing, but the x-intercept is at 1. A straight line that intercepts at 1. So it is two parallel lines that never ever touch. So this is a trick question.

HELP. How long is the minor axis for the ellipse shown below?
Given:
The equation of ellipse is
[tex]\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1[/tex]
To find:
The length of the minor axis.
Solution:
The standard form of an ellipse is
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] ...(i)
where, (h,k) is center, if a>b, then 2a is length of major axis and 2b is length of minor axis.
We have,
[tex]\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]b^2=16[/tex]
Taking square root on both sides.
[tex]b=\pm 4[/tex]
Consider only positive value of b because length cannot be negative.
[tex]b=4[/tex]
Now,
Length of minor axis = [tex]2b[/tex]
= [tex]2(4)[/tex]
= [tex]8[/tex]
So, the length of minor axis is 8 units.
Therefore, the correct option is B.
