An infinite sum of words that are expressed in terms of a function's derivatives at a single point is known as the Taylor series or Taylor expansion of a function in mathematics. Near this point, the function and the sum of its Taylor series are equivalent for the majority of common functions. The polynomial or function of an infinite sum of terms is the Taylor series. The exponent or degree of each succeeding term will be greater than the exponent or degree of the one before it.

Answer: 9 because 45% of 20 is 9

The coordinates of the endpoints after the transformation is (c) (7, 3) and (1, 5)

From the question, we have the following parameters that can be used in our computation:

Segment with endpoints at (1, 5) and (7, 3)

Also from the question, we have:

The points are reflected the segment about a vertical line through the segment’s own midpoint

When this is done, this means that the points would swap positions

So, we have the following representations

(1, 5) and (7, 3) ⇒ (7, 3) and (1, 5)

Answer: x=3√14

Step-by-step explanation:

Answer: To determine how much 5 inches of wire would cost at the same rate as 12 inches of wire, we can first determine the rate at which the wire is being sold by dividing the cost of the wire by the length of the wire:

36 cents / 12 inches = 3 cents/inch

We can then use this rate to determine the cost of 5 inches of wire by multiplying the rate by the length of the wire:

3 cents/inch * 5 inches = 15 cents

Therefore, 5 inches of wire would cost 15 cents at the same rate as 12 inches of wire.

In linear equation, 96 is the quotient.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                             Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

f(x) =  6x^3-+18x^2-18x+12

It is important to note that percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

Since Aunt Georgia has $1000 and bought a gadget for $300, the remaining amount will be:

= $1000 - $300

= $700

Therefore, since also agreed to pay 40% of the cost of the new UMSHQYGT 2000, which costs $649.99, she will have money left. This will be:

Answer:

88.75% is the percentage Tami earned.

The revenue function of Patrice Bergeron earnings is R(x) = (50 + 5x)(20 -x)

From the question, we have the following parameters that can be used in our computation:

Charges  = $50

Students = 20

Also, we have:

For every $5/hr he increases the price, he loses one student.

This means that

Charges  = 50 + 5x

Students = 20 - x

So, the revenue equation is

R(x) = Charges * Students

Substitute the known values in the above equation, so, we have the following representation

R(x) = (50 + 5x)(20 -x)

Hence, the function is R(x) = (50 + 5x)(20 -x)

Bearing is a topic that deals with angles and distance. Thus, the required answers to the given question are:

i. Distance of 1034.2 miles

ii. Bearing of [tex]158^{o}[/tex]

The speed of an object is the rate of movement of the object with time.

speed = [tex]\frac{distance}{time}[/tex]

So that:

distance = speed x time

i. In the given question; let the initial distance covered be represented by d, so that:

d = 250 x 2

  = 500 miles

ii. Let the second distance covered by the pilot be represented by D, so that:

D = 300 x 2

   = 600 miles

iii. Thus let the distance to the starting point be represented by x. From Cosine rule, we have:

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2abCos C

[tex]x^{2}[/tex] = [tex]500^{2}[/tex] + [tex]600^{2}[/tex] - 2(500 x 600)Cos [tex]140^{o}[/tex]

   = 250000 + 360000 - 600000(-0,7660)

   = 610000 + 459600

   = 1069600

x = [tex]\sqrt{1069600}[/tex]

  = 1034.22

x = 1034.2 miles

Using the Sine rule to determine the required internal angle, we have:

[tex]\frac{a}{Sin A}[/tex] = [tex]\frac{c}{Sin C}[/tex]

[tex]\frac{500}{Sin A}[/tex] = [tex]\frac{1034.22}{Sin 140}[/tex]

Sin A = [tex]\frac{500*0.6428}{1034.22}[/tex]

         = 0.3108

A = [tex]Sin^{-1}[/tex] 0.3108

   = 18.11

A = [tex]18^{o}[/tex]

To determine angle B, we have:

140 + 18 + B = 180 (sum of angles in a triangle)

158 + B = 180

B = 180 - 158

  = 22

B = [tex]22^{o}[/tex]

Thus, the required bearing is 180 - 22 = 158

Therefore the distance and bearing required to fly to starting point are 1034.2 miles and [tex]158^{o}[/tex] respectively.

What is dilation?

Dilation is the increase or decrease in the size of a figure by a scale factor. Rigid transformations preserve the shape of a figure. Examples of rigid transformation are reflection, rotation and translation.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.

Dilation is said to be a rigid transformation if the scale factor is equal to one.

Therefore the dilation by a scale factor of one produce an image congruent to its pre-image.
