According to the concept of differentiation the length of his shadow changing when he is 10 feet from the base of the light is 10 feet.
Here we have given that the height of man = 6 feet
And the Height of light is 15 feet
Then the Rate of walk by man is written as
=>dx/dt = 5 feet per second.
Here we have to find the rate at which the tip of his shadow is moving when he is 10 feet from the base of the light.
Here by using ratio of similar triangles we have write it as,
=> 15/y = 6/(y - x)
When we do the cross multiplication on it, then we get
=> 15(y - x) = 6y
=> 15y - 6y = 15x
=> 9y = 15x
When we dividing by 3 on both sides then we get
=> 3y = 5x
While we differentiating both sides with respect to t then we get
=> 3(dy/dt) = 5(dx/dt)
=> dy/dt = (5/3)(6)
When we simplify this one, then we get

tommy wants to hire a car to drive 850 miles in 8 days how much would it cost him to hire a car from the cheaper side.
Note if Tommy were to hire a car to drive 850 miles in 8 days under the price conditions given, it would cost him £575 to go with the cheaper company which is company B.
To compute the cheaper price, we need to work out how much it comes to if he went with either company.
Company A:
Daily Charge £20
Cost per mile 50p
Given that he goes 850 Miles ;
For 8 days,
His Total cost with Company A is
(20 x 8) + [ (50 *850)/100); recall that 100 pence (p) make 1 British Pound (£)
Thus, 160 + 425
= £585
Thus, to go with Company A, Tommy will spend £585
On the other hand, Tommy's Total cost with Company B is computed as follows;
Daily Charge £40
Cost per mile 30p
Total cost will come to: (40 x 8) + [(30 *850)/100)
= 320 + (25500/100)
= £575
Since Company will charge a total of £585 and Company B will charge a total of £ 575, we can conclude that the cheaper company is company B.

x³ = x² + 20x how do you solve this by factoring?
Answer:
Factors of x are 0, 5, and -4.
Step-by-step explanation:
⇒ x³ = x² + 20x
⇒ x³ - x² - 20x = 0
⇒ x (x² - x - 20) = 0
⇒ x ( x² - 5x + 4x - 20) = 0
⇒ x ( x ( x - 5) + 4 ( x - 5)) = 0
⇒ x (x - 5) (x + 4) =0
⇒ x = 0, 5, and -4
Answer: x = 5
x = -4
x = 0
Step-by-step explanation:The first term is, x2 its coefficient is 1 .
The middle term is, -x its coefficient is -1 .
The last term, "the constant", is -20
Step-1 : Multiply the coefficient of the first term by the constant 1 • -20 = -20
Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is -1 .
-20 + 1 = -19
-10 + 2 = -8
-5 + 4 = -1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 4
x2 - 5x + 4x - 20
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-5)
Add up the last 2 terms, pulling out common factors :
4 • (x-5)
Step-5 : Add up the four terms of step 4 :
(x+4) • (x-5)
Which is the desired factorization A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well. Solving x2-x-20 = 0 by Completing The Square .
Add 20 to both side of the equation :
x2-x = 20
Now the clever bit: Take the coefficient of x , which is 1 , divide by two, giving 1/2 , and finally square it giving 1/4
Add 1/4 to both sides of the equation :
On the right hand side we have :
20 + 1/4 or, (20/1)+(1/4)
The common denominator of the two fractions is 4 Adding (80/4)+(1/4) gives 81/4
So adding to both sides we finally get :
x2-x+(1/4) = 81/4
Adding 1/4 has completed the left hand side into a perfect square :
x2-x+(1/4) =
(x-(1/2)) • (x-(1/2)) =
(x-(1/2))2
Things which are equal to the same thing are also equal to one another. Since
x2-x+(1/4) = 81/4 and
x2-x+(1/4) = (x-(1/2))2
then, according to the law of transitivity,
(x-(1/2))2 = 81/4
We'll refer to this Equation as Eq. #4.2.1
The Square Root Principle says that When two things are equal, their square roots are equal.
Note that the square root of
(x-(1/2))2 is
(x-(1/2))2/2 =
(x-(1/2))1 =
x-(1/2)
Now, applying the Square Root Principle to Eq. #4.2.1 we get:
x-(1/2) = √ 81/4
Add 1/2 to both sides to obtain:
x = 1/2 + √ 81/4
Since a square root has two values, one positive and the other negative
x2 - x - 20 = 0
has two solutions:
x = 1/2 + √ 81/4
or
x = 1/2 - √ 81/4
Note that √ 81/4 can be written as
√ 81 / √ 4 which is 9 / 2
Find fx (1,0) and fy (1,0) and interpret these numbers as slopes for the following equation: f( x,y)= sqrt(4-x^2-4y^2) fx(1,0)= fy (1,0)=
The value of fx(1, 0) equal to -(1/√(3)) and fy(1, 0) is equal to -20/√3.
To find fx(1, 0) and fy(1, 0), we need to take the partial derivative of the given equation with respect to x and y respectively, and then evaluate the derivatives at the point (1,0).
First, we have f(x, y) = √(4 - x² - 4y²)
To find fx(1, 0), we'll take the partial derivative of f(x, y) with respect to x:
fx(x, y) = ∂f/∂x = -(x/√(4 - x² - 4y²))
Therefore, fx(1, 0) = -(1/√(4 - 1² - 4×0²)) = -(1/√(3))
fx(1, 0) = -(1/√(3))
To find fy(1,0), we'll take the partial derivative of f(x, y) with respect to y:
fy(x, y) = ∂f/∂y
= -2y/√(4 - x² - 4y²)
Therefore, fy(1, 0) = -20/√(4 - 1² - 4×0²) = -20/ √3
These numbers, fx(1, 0) and fy(1, 0), can be interpreted as slopes of the equation. The slope in this case represents the rate of change of the function in the x and y directions. A negative value for fx(1,0) means that as x increases by a small amount, the function value decreases by a small amount, while a value of 0 for fy(1,0) means that as y increases by a small amount, the function value does not change.

Answer: g(f(10)) = g(√2x+5) = 6x-3
We need to substitute x = √2*10 + 5 into g(x) = 6x - 3
g(f(10)) = 6(√2*10 + 5) - 3 = 6√20 + 30 - 3 = 6√20 + 27
So g(f(10)) = 6√20 + 27.
A tank hold 49 literof oil. If 7 liter leak what the percentage of oil ha leaed?
The percentage of oil that has leaked from the tank is 14.29%.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100.
Given that,
The capacity of the tank = 49 litres.
Total litres of oil leaked = 7 litres.
Mathematically, the percentage for the amount of oil leakage in this tank is given by this formula:
Percentage = oil leakage/tank capacity *100
Substituting the given parameters into the formula, we have:
Percentage = 7/49 *100 = 14.29%
Thus, The percentage of oil that has leaked from the tank is 14.29%.

Why is 1 called a universal factor?
1 is a universal factor. It is a factor of all numbers. The number itself is a factor of the number as it divides itself entirely.
A factor is a number that divides another number and leaves no remainder. In other words, if multiplying two whole numbers gives us a product, the numbers we are multiplying are factors of the product because they are divisible by the product. There are two processes for finding factors: multiplication and division.
For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 absolutely and 12 ÷ 6 = 2 absolutely. The other factors of 12 are - 1, 2, 4, and 12.

She wants twice as many roses as the other two types of flowers combined. Write a system of equations to represent this situation. How many of each type of flower should be in each bouquet?
The flowers was 8 roses, 2 lillies and 2 irises in each of the identical bouquet.
What is an equation?An equation is an expression composed of variables and numbers linked together by mathematical operations.
Let x represent the number of roses in each bouquet, y represent the lillies in each bouquet, and z represent the irises.
A florist must make 5 identical bridesmaid bouquets for a wedding. She has a budget of $160, hence:
Cost of flowers in each bouquet = $160/5 = $32
She wants 12 flowers in each bouquet, hence:
x + y + z = 12 (1)
She wants twice as many roses as the other two types of flowers combined, hence:
x = 2(y + z)
x - 2y - 2z = 0 (2)
Roses cost $2.50 each, lilies cost $4 each, and irises cost $2 each, hence:
2.5x + 4y + 2z = 32 (3)
From the equations:
x = 8, y = 2, z = 2
There was 8 roses, 2 lillies and 2 irises.

What is the type of systems of linear equations with infinitely many solutions?
The type of system of linear equations with infinitely many solutions is called a homogeneous system of linear equations.
A system of linear equations is a set of two or more equations with two or more variables that are related to each other. When a system of linear equations has an infinite number of solutions, it is called a homogeneous system of linear equations. This is because all the equations in the system are multiples of each other, so any solution of one equation is also a solution for all the other equations.

Answer:
The length of the third side (Hypotenuse) is 7.1556411313
Step-by-step explanation:
In order to find the third side(Hypotenuse) we use a formula called the phytogorean theorem which was invented by a philosopher named Pythagoras.
[tex]a^{2} +b^{2} =c^{2}[/tex]
We now apply the given values to the equation
[tex]5.96^{2} + 3.96^{2} = c^{2}[/tex]
Squaring the numbers we get,
[tex]35.5216+15.6816 = c^{2}[/tex]
[tex]51.2032[/tex] [tex]= c^{2}[/tex]
We now find the root of the number to find the hypotenuse which is,
[tex]\sqrt{51.2032} = c[/tex]
[tex]7.1556411313 = c[/tex]
Hence , the length of the third side (Hypotenuse) is 7.1556411313
