The series you had provided is generally the Maclaurin's series , and we want to prove the series , this series is very very much useful in calculus , especially when you have to substitute a function by it's series . So now let's start !
Consider the function f(x) as series of a polynomials of nth (n ≥ 1) degree as
[tex]{\boxed{\bf{f(x)=a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+a_{4}x^{4}+\cdots \cdots \infty}}}[/tex]
Now , at x = 0
[tex]{:\implies \quad \sf f(0)=a_{0}+a_{1}(0)+a_{2}(0)^{2}+a_{3}(0)^{3}+a_{4}(0)^{4}+\cdots \cdots \infty}[/tex]
[tex]{\boxed{:\implies \quad \sf f(0)=a_{0}}}[/tex]
Now , again consider the function that we assumed
[tex]{:\implies \quad \sf f(x)=a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+a_{4}x^{4}+\cdots \cdots \infty}[/tex]
Differentiating both sides w.r.t.x will yield
[tex]{:\implies \quad \sf f^{\prime}(x)=0+a_{1}\times 1+a_{2}\times 2\times x+a_{3}\times 3\times x^{2}+a_{4}\times 4\times x^{3}+\cdots \cdots \infty}[/tex]
[tex]{:\implies \quad \sf f^{\prime}(x)=a_{1}+2a_{2}x+3a_{3}x^{2}+4a_{4}x^{3}\cdots \cdots \infty}[/tex]
Now , put x = 0 ;
[tex]{:\implies \quad \sf f^{\prime}(0)=a_{1}+2a_{2}(0)+3a_{3}(0)^{2}+4a_{4}(0)^{3}\cdots \cdots \infty}[/tex]
[tex]{:\implies \quad \sf f^{\prime}(0)=a_{1}}[/tex]
[tex]{\boxed{:\implies \quad \sf a_{1}=\dfrac{f^{\prime}(0)}{1!}}}[/tex]
Now , consider ;
[tex]{:\implies \quad \sf f^{\prime}(x)=a_{1}+2a_{2}x+3a_{3}x^{2}+4a_{4}x^{3}\cdots \cdots \infty}[/tex]
Differentiating both sides w.r.t.x now ;
[tex]{:\implies \quad \sf f^{\prime \prime}(x)=0+2\times a_{2}\times 1+3\times a_{3}\times 2\times x+4\times a_{4}\times 3\times x^{2}\cdots \cdots \infty}[/tex]
[tex]{:\implies \quad \sf f^{\prime \prime}(x)=2a_{2}+6a_{3}x+12a_{4}x^{2}+\cdots \cdots \infty}[/tex]
Now , putting x = 0 will yield ;
[tex]{:\implies \quad \sf f^{\prime \prime}(0)=2a_{2}+6a_{3}(0)+12a_{4}(0)^{2}+\cdots \cdots \infty}[/tex]
[tex]{:\implies \quad \sf f^{\prime \prime}(0)=2a_{2}}[/tex]
[tex]{\boxed{:\implies \quad \sf a_{2}=\dfrac{f^{\prime \prime}(0)}{2!}}}[/tex]
Now , similarly we can prove that ;
[tex]{\boxed{:\implies \quad \sf a_{n}=\dfrac{f^{n}(0)}{n!}}}[/tex]
Now , as we had considered ;
[tex]{:\implies \quad \sf f(x)=a_{0}+a_{1}x+a_{2}x^{2}+a_{3}x^{3}+a_{4}x^{4}+\cdots \cdots \infty}[/tex]
Now , putting the values we obtained above ;
[tex]{:\implies \quad \sf f(x)=f(0)+\dfrac{x}{1!}f^{\prime}(0)+\dfrac{x^2}{2!}f^{\prime \prime}(0)+\dfrac{x^3}{3!}f^{\prime \prime \prime}(0)+\dfrac{x^4}{4!}f^{\prime \prime \prime \prime}(0)+\cdots \cdots \dfrac{x^n}{n!}f^{n}(0)+\cdots \cdots \infty}[/tex]

Formula for it heights above the ground (hm) after it has
travelled d m horizontally is h= 3/8(d-480), make d the subject of the formala.
Use your result to find d when h= 500m.
The value of d when h is 500m is approximately 1,813m
How to find the height of the aircraftGive the heights above the ground (hm) after it has dropped expressed as:
h = 3/8(d-480),
If h = 500m, then;
500 = 3/8(d - 480)
Cross multiply
500*8 = 3(d - 480)
4000 = 3(d - 480)
Expand to have:
4000 = 3d - 1440
3d = 5440
d = 1,813.3m
Hence the value of d when h is 500m is approximately 1,813m

The perimeter of the figure, rounded to the nearest tenth is: 17.2 units.
What is the Perimeter of a Figure?Perimeter of a figure is the total length of all sides of the figure.
The distance formula, [tex]d = \sqrt{(x_2 - x_2)^2 + (y_2 - y_1)^2}[/tex], can be used to find the length of each segment of a figure on a coordinate plane.
Thus, we have:
A(0, 4)
B(4, 4)
C(1, 0)
D(4, 1)
Perimeter of the figure = AB + BC + CD + DA
AB = |4 - 0| = 4 units
BC = √[(1−4)² + (0−4)²]
BC = √25
BC = 5 units
CD = √[(1−4)² + (0−1)²]
CD = √10
CD = 3.2 units
DA = √[(0−4)²+ (4−1)²]
DA = √25
DA = 5 units
Therefore:
Perimeter of the figure = 4 + 5 + 3.2 + 5 = 17.2 units.

A business owner opens one store in town A. The equation p(x)= 10,000(1.075)^ 5 represents the anticipated profit after t years. The business owner opens a store in town B six months later and predicts the profit from that store to increase at the same rate. Assume that the initial profit from the store in town B is the same as the initial profit from the store in town A. At any time after both stores have opened, how does the profit from the store in town B compare with the profit from the store in town A? 65% 96% 104% 154%
Answer:
It's 96%
Step-by-step explanation:
Just took the test
The profit from the store in town B compared with the profit from the store in town A is the ratio represented by 96%.
What is a ratio?The ratio is the simplest form of a fraction involving two quantities determining each other. It is written as a:b, read as "a is to b", and functions as a/b.
How to solve the question?In the question, we are given that a business owner opens one store in town A. The equation p(x)= 10,000(1.075)^t represents the anticipated profit after t years. The business owner opens a store in town B six months later and predicts the profit from that store to increase at the same rate.
We are asked to assume that the initial profit from the store in town B is the same as the initial profit from the store in town A and find the comparison between the profits from the store in town B to the store in town A.
We take the time for the store in town A as t1.
Then the time for the store in town B is t1 - 0.5, as store in town B is opened 6 months after the store in town A.
To compare the profits, we take the ratio of the profits from the stores.
= Profit from the store in town B/Profit from the store in town BA
= 10,000(1.075)^(t1 - 0.5)/10,000(1.075)^t1
= (1.075)^(t1 - 0.5 - t1)
= 1.075^(-0.5)
= 1/(1.075)^0.5
= 0.96448
= 96% (approx.)
Therefore, the profit from the store in town B compared with the profit from the store in town A is the ratio represented by 96%.

A cloud directly above you is about 10° across. From the weather report, you know that the cloud is at an altitude of 2200 m. How wide is the cloud?
The width of the cloud is 12500 meters wide.
The situation forms a right angle triangle.
What is a right angle triangle?Right angle triangle are triangle that has one of its sides as 90 degrees. The sides can be found using trigonometric ratios.
Therefore, the altitude is the opposite side of the triangle formed. The width of the cloud is the adjacent side of the triangle formed.
tan 10 = opposite / adjacent
Therefore,
tan 10° = 2200 / a
cross multiply
a = 2200 / tan 10°
a = 2200 / 0.1763269807
a = 12500 meters

Eric recorded the total number of push-ups he did each minute for four minutes write the order number pairs as ordered pairs
Answer:
(1, 15), (2, 30), (3, 45), (4, 60)
Step-by-step explanation:
So the values are already given to you in the table, it's just a matter of turning them into ordered pairs. Ordered pairs are a set of numbers that represent a point on the coordinate plane. On the graph, the x-axis (horizontal) is for time and the y-axis (vertical) is for the amount of push-ups. An ordered pair is (x, y) so you put (amount of minutes, amount of push-ups). For how they're related, how many push-ups he did increases by 15 for every minute. So, the y-value increases by 15 when the x-value increases by 1.
