find the first derivative of x^2+y^2=25​

Answers

Answer 1

Answer:

[tex]\frac{dy}{dx}=-\frac{x}{y}[/tex]

Step-by-step explanation:

Use implicit differentiation:

[tex]x^2+y^2=25\\\\2x+2y\frac{dy}{dx}=0\\ \\2y\frac{dy}{dx}=-2x\\ \\\frac{dy}{dx}=-\frac{x}{y}[/tex]

Remember to treat "y" as a constant in implicit differentiation and include dy/dx.

  cost = 33

Step-by-step explanation:

Kruskal's Algorithm is a "greedy" algorithm that adds the next minimum-weight edge to the tree, provided that it does not create a loop.

__

The minimum-weight edge in the graph is DF, with weight 1.

The next minimum-weight edge is GH, with weight 2.

The next minimum-weight edge is AB, with weight 3.

The next minimum-weight edge is EF, with weight 4.

Edge DE is the next lowest-weight, but it creates a loop (DEF), so we ignore it.

BC is the next edge we'll add to our tree.

FG is the next edge we'll add to the tree.

Edge DG creates a loop, so we ignore it.

Edge FH creates a loop, so we ignore it.

CF is the next edge we'll add to the tree. This completes the minimum spanning tree using Kruskal's Algorithm.

Included edges are AB, BC, CF, DF, EF, GF, GH.

The cost of the tree is 3+6+10+1+4+7+2 = 33.

7. A cylindrical tank can hold 2279.64 cubic feet of water. The radius of the tank is 11 feet. What is the height of the tank?

Answers

Answer:

r = 8.12

Step-by-step explanation:

The volume for a cylinder is V=πr^2h therefore,

v = 2279.64

h = 11ft

r = ?

2279.64 = πr^2 * 11

[tex]\frac{2279.64}{11}= {\pi r^2} \\[/tex]

207.24 = πr^2

[tex]\frac{207.24}{\pi} =r^2\\\\66 = r^2\\\\\sqrt{66} = r\\\\\\8.12 = r[/tex]

Which term best describes vthe figure shown below

Answers

Answer:

Line LM

Step-by-step explanation:

     A ray has a point at one end, this figure does not.

     A line goes out forever in both ends, this is shown by the two arrows. Line LM describes this figure.

     Points LM are going to be two separate points, this figure does not have points.

     Plane LM will have three points to show a plane, this is a single line.

     Using these definitions and facts we know, we can figure out this is best described as Line LM.

What is the volume of a rectangular prism?

The volume of a rectangular prism of length l, width w and heigth h is given by:

V = lwh.

In this problem, we have that the dimensions are given by:

w = x.l = x - 1.h = x - 2.

Hence the volume is given by:

[tex]V = x(x - 1)(x - 2) = x(x^2 - 3x + 2) = x^3 - 3x^2 + 2x[/tex]

What is the end behavior of a function?

It is given by it's limits as x goes to infinity.

Hence:

[tex]\lim_{x \rightarrow -\infty} V(x) = \lim_{x \rightarrow -\infty} x^3 - 3x^2 + 2x = \lim_{x \rightarrow -\infty} x^3 = -\infty[/tex]

[tex]\lim_{x \rightarrow \infty} V(x) = \lim_{x \rightarrow \infty} x^3 - 3x^2 + 2x = \lim_{x \rightarrow \infty} x^3 = \infty[/tex]

Which means that option B is correct.

since it's absolute value, this actually has two equations:

x-6=8

and

x-6=-8

we solve x-6=8 by adding 6 to both sides which equals x=14

we solve x-6=-8 by also adding 6 to both sides which equals x= -8+6= -2

Find the measures of the interior angles?

Answers

Answer:

Angle C = 35

Step-by-step explanation:

Angles A and B are already given to you, so I will not be explaining how to find them. If you have any questions, let me know.

There are 2 ways to solve this problem; you can either use the sum of the interior angles or isosceles triangles.

Sum of Interior Angles

The interior angles of all triangles equal 180 degrees. We can use this information to create an equation.

First, set up the equation.[tex]110+35+x=180[/tex]Then, combine like terms.[tex]145+x=180[/tex]Next, subtract 145 from both sides[tex]x=35[/tex]

This means that angle C equals 35 degrees.

Isosceles Triangles

The image shows marks on 2 sides. These marks show that the sides are congruent. If a triangle has 2 congruent sides then it is isosceles. Isosceles always have 2 congruent angles as well. In addition, these congruent angles are always the angles opposite of the congruent sides.

In this case, the angles opposite of the congruent sides are angle A and angle C. Thus, angles A and C are congruent. If angle A is equal to 35, then angle C must also be 35.

A cylinder has a diameter of 10 inches and a height of 14 inches. what is the volume of the cylinder? use 3.14 for pi?

Answer:

Volume of cylinder is 1099 in³

[tex]\\[/tex]

Step-by-step explanation:

[tex]\\[/tex]

Diameter of cylinder = 10 inchesHeight of cylinder = 14 inches

[tex]\\[/tex]

We know that,

[tex]\dashrightarrow \sf \: \: Radius = \dfrac{Diameter}{2} \\ \\[/tex]

[tex]\dashrightarrow \sf \: \: Radius = \dfrac{10}{2} \\ \\ [/tex]

[tex]\dashrightarrow \sf \: \: { \underline { \boxed{ \pmb{ \sf{ \pink{ Radius = 5 \: inches}}}}}} \\ \\ [/tex]

Using formula:

Where,

r is radius of the cylinderh is height of the cylinderπ = 3.14

[tex]\\[/tex]

Substituting the required values in the formula:

[tex]\dashrightarrow \sf \: \: Volume = 3.14 × (5)^2 × 14 \\ \\ [/tex]

[tex]\dashrightarrow \sf \: \: Volume = 3.14 \times 25 \times 14 \\ \\ [/tex]

[tex]\dashrightarrow \sf \: \: Volume = 78.5 \times 14 \\ \\ [/tex]

[tex]\dashrightarrow \sf \: \: { \underline{\boxed { \pmb{ \sf{ \pink{Volume = 1099 \: {in}^{3} }}}}}} \\ \\ [/tex]

Find the value of x. AB=20 BC=6 CD=8​

Answers

Step-by-step explanation:

there is the rule

outside length × (outside length + inside length) is the same for all lines originating from the same point.

so, we have

CD(CD + x) = BC(BC + AB) = 6(6+20) = 6×26 = 156

8(8 + x) = 156

8 + x = 19.5

x = 11.5

Answer:

the 852 is the perfect fit q3

Step-by-step explanation:

The five-number summary of this data set are minimum is 515, maximum value is 986, Q₁ is 686, Q₂ is 852 and Q₃ is 966.

What is Median?

Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order. It is also called second quartile.

Given data set is,

{852, 687, 515, 986, 907, 784, 967, 685, 965}

Arrange this in ascending order first.

{515, 685, 687, 784, 852, 907, 965, 967, 986}

Minimum value = 515

Maximum value = 986

First we have to find the median or the second quartile.

Second quartile, Q₂ = Middle element of the set

Q₂ = 5th element = 852

First quartile = 1/4 (n + 1)th element = 1/4 (9 + 1) = 2.5 th element

Q₁ = (685 + 687) / 2 = 686

Third quartile = 3/4(n + 1)th element = 3/4 (9 + 1) = 7.5th element

Q₃ = (965 + 967) / 2 = 966

Hence the five-number summary of this data set are found.
