The equation for the normal line B gives us :
L: (x,y,z) = (0,0,7) + t(1, 1, 1), t ∈ R
Find the solution ?
Full question is:
Find equations of the tangent plane and the normal line to the given surface at the specified point. x + y + z = 7e(xyz) at a specified point (0, 0, 7)
If we have a level surface, then it will give us
f(x,y,z) = x+y+z = 7e(xyz). where f is the function of the x, y, and z coordinates.
Now let us calculate the ∇ gradient of f at point (0,0,7):
∇ = (fx,fy,fz) = (1−7yz,1−7xz,1−7xy)
= (1, 1, 1)
We get the equation for the tangent plane A:
A: 1(x−0) + 1(y−0) + 1(z−7)=0
This can also be written as:
x+y+z = 7 ------------------------------------------------------------------(a)

3 Question* (1 Point) 3) The volume of Lake Superior is approximately 1.22 x 10 4 cubic kilometers. The volume of the Pacific Ocean is approximately 6 x 10 8 cubic kilometers. Write About It! About how many times larger is the Pacific Ocean than Lake Superior? Write a mathematical argument that can be used to defend your solution.
Answer:
The Pacific Ocean is approximately 4.9 times larger than Lake Superior in terms of volume. This can be shown through the following mathematical argument:
First, divide the volume of the Pacific Ocean by the volume of Lake Superior to determine the size ratio:
6 x 10^8 cubic kilometers / 1.22 x 10^4 cubic kilometers = 4.9
This shows that the Pacific Ocean is approximately 4.9 times larger than Lake Superior.
To defend this solution, we can use the concept of ratio and proportion. We know that the ratio of the volumes of the two bodies of water is equal to the ratio of their respective sizes. Therefore, by finding the ratio of the volumes, we can determine the size ratio.
In this case, the ratio of the volumes is 6 x 10^8 cubic kilometers / 1.22 x 10^4 cubic kilometers, which simplifies to 4.9. This means that the Pacific Ocean is 4.9 times larger than Lake Superior in terms of volume.
This solution can be further supported by the fact that the Pacific Ocean is the largest ocean in the world, while Lake Superior is one of the Great Lakes and is much smaller in size.

What are the properties of angles?
The angle properties of lines are:
Vertically opposite angles are equal, for example, a = d, b = c.
Adjacent angles add to 180, for example, a + b = 180, a + c = 180. Corresponding angles are equal, for example, a = e, b = f, c = g, d= h.
(2) In the given figure, m∠BFC = 42°

How do you convert 2−2i to polar form?
2 - 2i can be written in polar form as [tex]2\sqrt{2} \ cis\frac {-3\pi}{4}[/tex]
To convert a complex number in Cartesian form (such as 2 - 2i) to polar form, you can use the following steps:
Find the magnitude (or absolute value) of the complex number. This is the distance from the origin to the point representing the complex number in the complex plane. The magnitude of 2 - 2i is approximately 2.83.Find the argument of the complex number. This is the angle between the positive real axis and the line connecting the origin to the point representing the complex number in the complex plane. To find the argument, you can use the inverse tangent function (also known as arctangent or atan). The argument of 2 - 2i is approximately -135 degrees, or -2.356 radians.Combine the magnitude and argument to express the complex number in polar form. In polar form, a complex number is written as "magnitude (angle)", where the angle is expressed in either degrees or radians. So, the polar form of 2 - 2i is approximately 2.83 (-135 degrees) or 2.83 (-2.356 radians).To learn more about complex number, visit:

The base of the triangle is decreasing at the rate of 1.6 cm/min.
Given
dh/dt = 1 cm/min
dA/dt = 2 cm2/min
When A = 100 cm2, h = 10 cm
We know that
A = 1/2 × b × h
b = 20 cm
Let us differentiate both sides
dA/dt = 1/2 [b dh/dt + h db/dt]
Substituting the values
2 = 1/2 [20 × 1 + 10 × db/dt]

queuing system a has a utilization of 80 percent, and queuing system b has a utilization of 90 percent. both have a single server. say the utilization of both systems increases by 5 percent; that is, a increases from 80 percent to 85 percent while b increases from 90 percent to 95 percent. which system is likely to experience the bigger change in the average time in queue?
For queuing system B, the average time in queue ids going to change significantly as a result of increased utilization.
This is because queuing system B is initially heavily loaded and has less capacity to handle more requests. As a result, an increase in utilization can cause a significant increase in average queue latency on system B compared to system A.
Average Queue Time is a measure of the time a customer or request spends being processed by a server. It is affected by several factors such as server load, customer or request arrival rate, and server service rate. As the load on the queuing system increases, it means that the server is being used more frequently and is no longer available to process incoming requests. This will increase the average time in the queue as more requests accumulate and have to wait to be processed. The greater the increase in occupancy, the greater the impact on average latency.

please help me im so confused
Answer:
It looks like you have an inequality equation with one variable, but the equation is incomplete. In order to solve the inequality, we need to have a complete equation with a left-hand side and a right-hand side.
For example, if we wanted to solve the inequality 8y - 5 < 3, we could complete the equation by adding 5 to both sides:
8y - 5 + 5 < 3 + 5
8y < 8
Then, we could divide both sides of the inequality by 8 to solve for y:
8y/8 < 8/8
y < 1
Therefore, the solution to the inequality 8y - 5 < 3 is y < 1.

Calculate the value of x.

Answer:
x = 2.5 mm-------------------------------------
Set equation for area of given shape:
x*4 + x*(2x + 3) = 30Simplify and solve for x:
4x + 2x² + 3x = 302x²+ 7x = 302x² + 7x - 30 = 0x = [-7 ± √(7² - 4*2*(-30))] /4x = (-7 ± √289)/4x = (-7 ± 17)/4x = (10/4) and x = (- 24)/4 (discarded as negative number for the segment length)x = 2.5 mmAnswer:
x = 2.5 mm
Step-by-step explanation:
A compound shape is made up of two or more basic shapes.
From inspection of the given compound shape, we can see that it is made up of two rectangles.
[tex]\boxed{\begin{minipage}{4 cm}\underline{Area of a rectangle}\\\\$A=w \cdot l$\\\\where:\\ \phantom{ww}$\bullet$ $w$ is the width. \\ \phantom{ww}$\bullet$ $l$ is the length.\\\end{minipage}}[/tex]
Dimensions of the smaller rectangle:
w = xl = 4 mmDimensions of the larger rectangle:
w = xl = (2x + 3) mmTherefore, the equation for the area of the compound shape is:
[tex]\begin{aligned}\implies \textsf{Area}&=x \cdot 4 + x \cdot (2x+3)\\&=4x+x(2x+3)\\&=4x+2x^2+3x\\&=2x^2+7x\end{aligned}[/tex]
Given the area of the compound shape is 30 mm², substitute this value into the found equation for area and solve for x:
[tex]\begin{aligned}\implies 2x^2+7x &=30\\2x^2+7x-30&=0\\2x^2+12x-5x-30&=0\\2x(x+6)-5(x+6)&=0\\(2x-5)(x+6)&=0\\\\2x-5&=0 \implies x=2.5\\x+6&=0 \implies x=-6\end{aligned}[/tex]
