What is derivative mean?
The rate at which a function changes in relation to a variable Calculus and differential equations issues must be solved using derivatives.In order to determine the rate of change of an interest variable, scientists typically observe changing systems (dynamical systems).They then incorporate this information into a differential equation and use integration techniques to produce a function that can be used to predict how the original system will behave under various conditions.Geometrically, the slope of a function's graph or, more accurately, the slope of the tangent line at a point can be used to understand the derivative of a function.d(u/v) = [ u(dv/dx) + v(du/dx) ] / v²
Given:
f(x) = x²/x²+1
Applying the formulae:
= x²[ d(x²+1)/dx] + (x²+1) [ d(x²)/dx ] / (x²+1) ²
= x²(2x+0) + (x²+1)2x / (x²+1) ²

Let sample space be S={1,2,3,4,5,6,7,8,9,10} suppose the outcomes are equally likely. Compute the probably of the event E=“ an odd number less than 9”
Answers
The probability of the event E i.e an odd number less than 9 is 0.4.
The probability of an event is a ratio of number of favorable outcomes to total number of outcomes. The sum of all probabilities of events must be equal to one. The probability of an event must not be greater than 1.
In event E i.e an odd number less than 9, the number of favorable outcome is 4 i.e. {1,3,5,7}.
The total number of outcomes is whole set S i.e. 10.
So, the probability of event E will be,
P(E) [tex]=\frac{4}{10}[/tex]

How much engine oil should be added to a jerry can that contains 4.3 gallons of gas?
Answers
The amount engine oil which should be added to a jerry can that contains 4.3 gallons of gas is 0.172 gallons.
Given that arborist is preparing the fuel mix for her chainsaw before climbing a tree to remove a dead limb when two-stroke chainsaw requires a 4% mix of engine oil to gas and the amount of oil should be 4% of the amount of gas.
We want to find the amount of engine oil which should be added to a jerry can that contains 4.3 gallons of gas.
To find the amount of engine oil convert the mixture of engine oil to gas into decimal.
4%=4/100
4%=0.04
Now, we will multiply the above mixture with 4.3 gallons of gas is
4.3×0.04=0.172 gallons

How to find the effective interest rate?Given data:
Principal = $8,000
Rate =6 1/2% or 6.5%
Term= 300 Days
a. Proceeds
Interest = Principal x Rate x Time
Interest = $8,000 x 6.50% x 300/360
Interest = $8,000 x 0.065 x 0.8333
Interest = $433.33
Now let find the Proceeds:
Proceeds = $8,000 - 433.33
Proceeds = $7,566.67
b. Effective Interest Rate:
Effective Interest Rate = 433.33 / 7566.67 x 300/360
Effective Interest Rate = 433.33 / 6305.56
Effective Interest Rate = 0.0687 × 100

(b) Solve the problem. (Round your answer to the nearest cent.)

Answers
The income that this settlement provide at the end of each month is: $813.20.
How to find the monthly payment?Monthly amount= $1.500,000 at the end of year 35 years.
Interest rate per month = 7.1/12 = 0.59167% per month
Total periodic cash flow = 35× 12 = 420
Hence,
Future value of annuity = X × [(1+ 0.0059167)^420 -1/ 0.0059167]
Future value of annuity =X × [(1.0059167)^420 -1/ 0.0059167]
Future value of annuity = X × [(1.0059167)^420 -1/ 0.0059167]
Future value of annuity = X × [11.913727 -1 / 0.0059167]
Future value of annuity = X × [10.913727 / 0.0059167]
Future value of annuity =X × 1,844.5633
$1,500,000 = X × 1,844.5633
X = $1,500,000/ 1,844.5633
X = $813.20
Hence,
Monthly payment is $813.20.

62.79 divided by 23 long division

Step-by-step explanation:
this is a college question ????
and you don't know how to do it ? what happened to you in elementary school ?
there are many different techniques. everybody thinks theirs is the fastest or easiest to understand.
after all, this is just "playing" with numbers, the factors embedded within the dividend.
this is mine. when I was in elementary school, we called this the "long division" :
62.79 ÷ 23 =
we pick the first few positions from the left of the dividend, where we are sure, the divisor fits at least once.
in our case here : 62.
we do an integer divide of 62/23 = 2 (for 3 the dividend would have to be at least 69). this 2 is our first digit of the quotient.
62.79 ÷ 23 = 2
now we multiply the divisor by that digit and subtract the result from the dividend. this gives us a remainder of 16, and we pull down the next position (7) :
62.79 ÷ 23 = 2
- 46
---------
167
now, we pulled the first digit after the decimal point, and we need to set the decimal point there in our quotient :
62.79 ÷ 23 = 2.
- 46
---------
167
now, we repeat the process by integer dividing this new dividend (167) by the divisor (23)
167/23 = 7
this 7 becomes the next digit in our quotient. and we repeat the process of multiplying this by the divisor and subtracting the result from the dividend. this gives us a remainder (6), and we pull down the next digit (9).
62.79 ÷ 23 = 2.7
- 46
---------
167
- 161
----------
69
and again, we repeat by integer dividing the new dividend (69) by the divisor (23)
69/23 = 3
this 3 is the next digit in our quotient.
we multiply it with the divisor and subtract the result from the dividend.
if the remainder is still not 0, we need to repeat the process by pulling the next digit, which would be an invisible 0. and continue.
but luckily, after this the remainder is 0, and we are finished.
62.79 ÷ 23 = 2.73
- 46
---------
167
- 161
----------
69
- 69
--------------
0
so, 62.79 ÷ 23 = 2.73 and 0 remainder.

Step-by-step explanation:
You want to know the correct descriptors of the domain, range, slope, and intercepts of the graph of y = ∛(x-1) +2.
DomainThe domain of the cube root function is all real numbers. Hence the graph has a domain of all real numbers.
RangeThe range of the cube root function is all real numbers. Hence the graph is not restricted to a range of y ≥ 1.
SlopeThe slope of the cube root function is positive everywhere. The graph of y is increasing as x is increasing.
InterceptsThe x-intercept is the value of x that makes y = 0.
0 = ∛(x -1) +2
-2 = ∛(x -1)
-8 = (x -1)
-7 = x . . . . . . . the x-intercept
The y-intercept is the value of y when x = 0.

(a) The graph has a domain of all real numbers.

A country's population in 1994 was 182 million. In 2002 it was 186 million. Estimate growth formula. Round your answer to the
the population in 2004 using the exponential
nearest million.
Answers
The growth formula for the given population is P = 182eⁿˣ and the population in 2004 is 186.98 million
Growth function:
Basically, the growth function means the pattern of data that shows greater increases with passing time, creating the curve of an exponential function.
Given,
A country's population in 1994 was 182 million. In 2002 it was 186 million.
Here we need to find the growth formula and the population in 2004.
According to the given problem, let us consider that the
final population P,
the starting population A, and
the time passed t.
Here we need to determine the value of the growth factor k.
And it can be calculated using the information for the years 1994 and 2002.
Here we know that, A will be 182 million (the population in 1994), P will be 186 million (the population in 2002), and t will be 8 years (the number of years between 1994 and 2002):
⇒186 = 182eⁿˣ⁸
⇒186/182 = e⁸ⁿ
Now, by applying ln to both sides of the equation:
⇒ln(186/182) = ln(e⁸ⁿ)
Using the laws of logarithms:
=> 8n = ln(186) - ln(182)
=> n = [ln(186) - ln(182)] / 8
=> n = 0.0027
Now, let's use this information to determine P in 2004.
Here the value of A will still be 182 million, but t will be 10 years.
Now, we have to apply these values then we get,
=> P = 182e⁰°⁰⁰²⁷ˣ¹⁰
=> P = 182e⁰°⁰²⁷
=> P = 182 x 1.0273
=> P = 186.98
Therefore, there are 186.98 million in 2004.

An arrow released from a bow, traveling towards a target 200 yards away,
reaches a max height of 42.6 ft in only 1.5 seconds. What is the height of the
arrow at 2.5 seconds?
Thank you so much!
Answers
The height of the arrow at 2.5 seconds is 71 feet.
Given:
An arrow released from a bow, traveling towards a target 200 yards away,reaches a max height of 42.6 ft in only 1.5 seconds.
1.5 seconds = 42.6 feet
divide by 1.5 on both sides.
1 sec = 28.4 feet
0.5 sec = 28.4/2
0.5 sec = 14.2 feet
2.5 sec = 1.5 sec + 1 sec
= 42.6 + 28.4
= 71 feet
Therefore The height of the arrow at 2.5 seconds is 71 feet.

What is a number increased by three is greater than zero or less than or equal to negative three?
Answers
The number is defined by the two inequalities:
x > -3
x ≤ -6
How to find the number?
If we define x as the number, the number increased by 3 is written as:
x + 3
If this is greater than zero or less than or equal to negative three, we can write two inequalities:
x + 3 > 0
x + 3 ≤ -3
Solving both inequalities for x (isolting it) we will get:
x > 0 - 3
x > -3
and:
x ≤ -3 - 3
x ≤ -6
So we have the two inequalities that define the number:
x > -3
x ≤ -6
