The value is 1
From the question, we have

Differentiate the above form, we get

Now substitute the limit,

L’Hospital’s Rule :
An input value that a function approaches and yields some result is referred to as a limit. Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity. A general technique for assessing indeterminate forms like 0/0 or / is the L'Hospital rule. L'Hospital's rule is applied to calculate the limits of indeterminate forms for calculus derivatives. It is possible to use the L Hospital rule many times. This rule is still valid after being applied, and it will take any indefinite form. L'Hospital's Rule cannot be applied if the issue is not of the indeterminate types.

write your answer in exponential form. 8^5 multiply 8^-2
Answers
Answer: 8^3
Explanation:
We want to multiply 8^5 multiply 8^-2
We would apply the rule of exponent;
a^b * a^c = a^(b + c)
By comparing both expressions,
a = 8
b = 5
c = - 2
Thus, we have
8^5 * 8^-2 = 8^(5 + - 2) = 8^(5 - 2)
= 8^3

Answers
The total amount of soda is

[tex]\begin{gathered} 3\frac{1}{2}=\frac{2\cdot3+1}{2}=\frac{7}{2} \\ \text{and} \\ 5\frac{3}{4}=\frac{4\cdot5+3}{4}=\frac{23}{4} \end{gathered}[/tex]so, the total amount of soda is given by
[tex]\frac{7}{2}+\frac{23}{4}[/tex]which gives
[tex]\begin{gathered} \frac{7}{2}+\frac{23}{4}=\frac{14}{4}+\frac{23}{4}=\frac{14+23}{4}=\frac{37}{4} \\ \end{gathered}[/tex]Now, we must subtact 2 3/8 of soda and we must convert it into a simple fraction form:
[tex]2\frac{3}{8}=\frac{8\cdot2+3}{8}=\frac{19}{8}[/tex]Then, Dan's family drank:
[tex]\frac{37}{4}-\frac{19}{8}[/tex]which gives
[tex]\frac{37}{4}-\frac{19}{8}=\frac{74}{8}-\frac{19}{8}=\frac{55}{8}[/tex]that is, they drank 55/8 of soda. In mixed fraction form, this result is equivalent to

The factor of the given polynomial is (m - 2n)(m - 5n).
What is termed as the factors of polynomial?Factors of polynomials are zeros of polynomials depicted in the form of some other linear polynomial. If we divide a given polynomial by any of its factors after factorisation, the remainder would be zero. We also factor the polynomial in this process by locating its greatest common factor.For the given question, the polynomial is -
= m² - 7mn + 10n²
We know that 10 = 5×2, thus break the equation like.
= m² - 2mn - 5mn + 10n²
Take m common from first two terms and -5n common from last two terms.
= m(m - 2n) - 5n(m - 2n)
Take common, (m - 2n).
= (m - 2n)(m - 5n)
Thus, the required factors of the given polynomial is (m - 2n)(m - 5n).

f(x) = |x+1|-1; vertical stretch by a factor of 3
Answers
The image of the function after vertically stretched by a factor of 3 is f'(x) = 3|x + 1| - 3
How to determine the equation of f(x) after the transformation?From the question, the given parameters are:
f(x) = |x + 1| - 1
The transformation is given as
Vertical stretch by a factor of 3
This implies that we stretch the function f(x) by a factor of 3 across the origin
Mathematically, this transformation can be represented as
(x, y) = (x, 3y)
When represented as a function, we have
f'(x) = 3 * f(x)
Substitute the equation f(x) = |x + 1| - 1 in the equation f'(x) = 3 * f(x)
So, we have the following equation
f'(x) = 3 * (|x + 1| - 1)
Remove the bracket
So, we have
f'(x) = 3 * |x + 1| - 3 * 1
Evaluate the products
So, we have
f'(x) = 3|x + 1| - 3
Hence, the equation of f'(x) is f'(x) = 3|x + 1| - 3

Answers
Camelle should buy a total of 4y practice jerseys for the team
How to determine the total number of practice jerseys?From the question, the given parameters are:
Number of players in the team = y players
Number of practice jersey for each player = 4 practice jerseys for each player
The total number of practice jerseys is the product of the number of players in the team and the number of practice jersey for each player
This is represented as
Total number of practice jerseys = Number of players in the team x Number of practice jersey for each player
Substitute the known values in the above equation
So, we have the following equation
Total number of practice jerseys = y players x 4 practice jerseys for each player
Evaluate the products
Total number of practice jerseys = y x 4 practice jerseys

Answers
One possible length of the third side of the given triangle is 15
Determining a possible length of a side of a triangleFrom the question, we are to determine a possible length of the third side of the triangle
From one of the properties of a triangle, we know that
The sum of any two sides of a triangle is greater than the third side and the positive difference of any two sides of a triangle is lesser than the third side.
Thus,
8 + 17 is greater than the third side
25 is greater than the third side
and
17 - 8 is lesser than the third side
9 is lesser than the third side
If the third side of the triangle is x,
Then,
9 < x < 25
Hence, a possible value of x is 15

The formula for finding the midpoint of two coordinates is expressed as;

L = (-13, 0)
Get the midpoint of KL;

(1) √15 is an irrational number.
(2) The point graphed on the number line is estimated.
Any number that cannot be stated as a fraction of any integer is considered to be irrational. The decimal expansions of irrational numbers are neither periodic nor do they come to an end. Every number that is transcendental is illogical.
When multiplied by itself, the square root of 15 produces the original integer 15. The square root of 15 is an irrational number since it cannot be expressed in the form of p/q.
Therefore, √15 is an irrational number.
The value of √15 in decimal is 3.87298334621 and hence, the point graphed on the number line is estimated but not an exact answer.

With the informationabout the rectangle, we can say the angle between the diagonal and the longest side (unknown) is 30°. While the shortest side is 50.
Then, to estimate the length of the remaining side (DC, which is equal to AB), we can state the following relationship:
[tex]\tan 30^o=\frac{50}{AB}=\frac{50}{DC}[/tex]Then:
[tex]DC=\frac{50}{\tan30^o}=\frac{50}{\sqrt[]{3}/3}=\frac{3\cdot50}{\sqrt[]{3}}[/tex]We can multiply numerator and denominator by square root of 3 to simplify:
[tex]DC=\frac{3\cdot50}{\sqrt[]{3}}=\frac{\sqrt[]{3}\cdot3\cdot50}{\sqrt[]{3}\cdot\sqrt[]{3}}=\frac{\sqrt[]{3}\cdot3\cdot50}{3}=50\sqrt[]{3}\approx86.6[/tex]The length of side DC is approximately 86.6. The correct answer is the fourth option.
