What is the length of a side of the pentagon?

Answer:

c

Step-by-step explanation:

Hyperbola is the conic section described by the equation 4x² = 10 +y²

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

To identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,

Ax²+By²+Cx+Dy+E=0

The given equation is 4x² = 10 +y²

4x²-y²=10

Divide the whole equation by 10

4x²/10 - y²/10=1

2x²/5- y²/10=1

x²/(1/2)- y²/10=1

The given equation is in the form of hyperbola.

Hence, hyperbola is the conic section described by the equation 4x² = 10 +y²

Step-by-step explanation:

Answer:

a) t = 7x + 15

b) Nicole is paid $50 for 5 hours.

Step-by-step explanation:

flat fee = a price that will not change = $15

$7 per hour = a price of $7 for an unknown amount of hours (x) = 7x

Let "x" = amount of hours.

Let "t" = total cost.

Set the equation:

t = 7x + 15

Nicole babysits for 5 hours. Plug in 5 for x in the equation:

t = 7x + 15

t = 7(5) + 15

t = 35 + 15

t = 50

Nicole is paid $50 for 5 hours.

Answer:

35°

Step-by-step explanation:

Produce BC in the direction of C which intersects DE at any point say P.

AB || ED... (given)

So, BP would be transversal.

[tex] \therefore m\angle DPB + m\angle FBP = 180\degree\\... (By\: interior \: \angle \: Postulate) \\

\therefore m\angle DPB + 125\degree = 180\degree\\

\therefore m\angle DPB = 180\degree - 125\degree \\

\huge \red {\boxed {\therefore m\angle DPB = 55\degree}} \\

m\angle DCP = 180\degree - 90\degree \\

m\angle DCP = 90\degree \\

x = 180\degree - (90\degree + 55\degree) \\

x = 180\degree - 145\degree \\

x = 35\degree [/tex]

The value of x or the angle CDE will be 35 degrees.

The theorem of vertical angles or angles that are vertically opposing According to the theorem, two opposing vertical angles that are created when two lines cross one other are always equal to one another.

Given that the angle CBF is 125 degrees. The value of the angle CDE will be calculated as below:-

Calculate angle ABC by using supplement angle property:-

∠ABC = 180 - 125 = 55

Draw a horizontal line PQ at point C.

Angle PCQ = 35

Angle CDE = 35

Therefore, the value of x or the angle CDE will be 35 degrees.

We can simply each answer choice to find those which have no solution:

1.  6x + 1 = 3(2x - 4)

6x + 1 = 6x - 12

0 ≠ - 13, NO SOLUTION.

2.  2 - 5x = 7x - 12

14 = 12x

x = 7/6. 1 SOLUTION.

3.  4(3 - x) = 2(6 - 2x)

12 - 4x = 12 - 4x

0 = 0. INFINITE SOLUTIONS.

4.  5(x + 2) = 2(x - 4)

5x + 10 = 2x - 8

3x = -18

x = -6. 1 SOLUTION.

5.  -4(x + 3) = 4(-x - 1)

-4x - 12 = -4x - 4

0 ≠ 8. NO SOLUTIONS.

Therefore, the only equations with no solutions are equations 1 and 5.

Answer:

 x + 1 = 3(2x – 4) and –4(x + 3) = 4(–x – 1).

Answer:

The correct answer is H. Independent variable.

Step-by-step explanation:

The independent variable, typically represented with the variable x, is the input of the function.  In an experiment, this is the variable that the scientist changes in order to see a change in the dependent variable.  The independent variable is usually plotted along the x-axis and its values represent the domain of the function.

The dependent variable, conversely, is typically represented with the variable y, and represents the output of the function.  In an experiment, the dependent variable would represent that change that occurs due to a change in the independent variable.  The dependent variable is usually plotted along the y-axis and its values represent the range of the function.

A survey is defined as the collection of the data or o=interpretation of the data using a list of questions asked to a particular sample of a population which determines the whole population.

From the given options, we can clearly say that C and D are not an example of a survey since survey doesn't make use of the comparison process.

In both C and D, effectiveness of mouthwash and hair product are done by comparing two groups.

So it is not a survey.
