Answer: Logarithmic differentiation when the logarithm of an expression can be written in a form for which we can find the derivative more simply. Or, for which we can find the derivative at all.

15x = 180

divide both by 15, and you get

x = 12

I'm unsure if this is correct

 Answer: Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees

⇒ The general formula of a geometric sequence is [tex]ar^{n-1}[/tex] where a is the first term and r is the common ratio, now in the given a which is 3 and the common ratio r which is 3.

to get the 10th term we use the same general formula

[tex]a_{n} =ar^{n-1}[/tex]

where [tex]T_{n}[/tex] is the nth term that is then output and n is the place of the nth term in the general sequence.

For the 10th term we substitute  10 in the place of n and simplify to find the value of the output.

[tex]a_{10} =ar^{(10-1)} \\a_{10} =ar^{9} \\[/tex]

Now since we know which formula to use to get the 10th term we can substitute the known values of the variables to get the output .

[tex]a_{10} =(3)(3)^{9} \\a_{10} =59049[/tex]

Step-by-step explanation:

Answer: 0,5

x = 0
y = 5

Answer: (0,5)

Step-by-step explanation:

Since "y" is equal to -6x+5 everywhere you see a "y" you can replace it with -6x+5.

-2x-6x+5=5

Combine like terms

-8x+5=5

Isolate x (subtract 5 from both sides)

-8x=0

Solve for x

x=0

Now that you have the value for "x" you can substitute the value into either equation and solve for y

-2(0)+y =5

y=5

or

y=-6(0)+5

y=5

two equations are: v = u + 0.5a and (v)² = (u)² + 4a.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given, the distance traveled by an object in t = 30 minutes is 2 miles

Let "v" be the final velocity of an object,

"u" be the initial velocity of an object,

and "a" be the acceleration of an object.

From the standard velocity equation:

final velocity = initial velocity + acceleration * time.....(1)

(final velocity)² = (initial velocity)² + 2*acceleration * distance....(1)

From equation (1)

v = u + a*30 minutes

time in hours,

v = u + 0.5a

From equation (2)

(v)² = (u)² + 2*a* 2

(v)² = (u)² + 4a

therefore, two equations are: v = u + 0.5a and (v)² = (u)² + 4a.

Answer:

Step-by-step explanation:

Let's call the original volume of water in the pitcher "V". Then, after Mai added 2.6 liters, the total volume of water in the pitcher became V + 2.6 = 10.4 liters.

To find the original volume of water in the pitcher, we can isolate V by subtracting 2.6 from both sides of the equation:

V + 2.6 = 10.4

V = 10.4 - 2.6

V = 7.8 liters

So the original volume of water in the pitcher was 7.8 liters.

Answer:

The answer is 20, so the answer is (D) 20.

Step-by-step explanation:

Let's say x is the number of tokens purchased for each of the three types. Then, the total amount spent is 0.10x + 0.15x + 0.20x = $9.

Combining like terms, we get 0.45x = $9.

Finally, dividing both sides by 0.45, we get x = 20.

So, 20 tokens were purchased for each of the three types.

The answer is 20, so the answer is (D) 20.

The statement which is given as , "The product of permutation matrices is again a permutation matrix." is True.

A permutation matrix is a square matrix whose entries are either 0 or 1 and has exactly one "1" in each row and each column. In other words, it is a matrix that represents a permutation of the rows (or columns) of the identity matrix.

When two permutation matrices are multiplied, the result is another square matrix with exactly one "1" in each row and each column. To see why this is true, consider two permutation matrices, A and B. Suppose that A is a m x m matrix and B is a m x m matrix. The product of these two matrices is another m x m matrix, C = AB.

Each entry in the matrix C is given by the dot product of the corresponding row in A and the corresponding column in B. If the row in A has a "1" in the i-th position and the column in B has a "1" in the j-th position, then the i,j-th entry in C will be "1".

Since both A and B are permutation matrices, each row in A and each column in B has exactly one "1". This means that each row in C will have exactly one "1", and each column in C will also have exactly one "1". Hence, C is also a permutation matrix.

The result is 45a^3b^4+4b

The given expression is 45a^3b^4+36a^2b^5 ÷ 9a^2b^4 First, we will simplify the term 36a^2b^5 ÷ 9a^2b^4 by dividing the coefficients and subtracting the exponents of the variables.

36 ÷ 9 = 4

a^2 ÷ a^2 = a^(2-2) = a^0 = 1

b^5 ÷ b^4 = b^(5-4) = b^1 = b

So, 36a^2b^5 ÷ 9a^2b^4 = 4b

Now, we can substitute this value back into the original expression:

45a^3b^4+4b

We cannot simplify this expression any further since the terms do not have the same power of the variables.

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.

Given:

The polynomial zeros are given as:

x = 7, x = -1 and x = -3

x - 7 = 0, x + 1 = 0 and x + 3 = 0

So, f(x) = (x - 7)(x + 1)(x + 3)

f(x) = (x - 7)(x² + 4x +3)

f(x) = x³ -3x² -25 x -21

Now, Rational function g(x)

g(x) = f(x) / (x² - x + 2)

After Factorizing

g(x) = (x-2) - 25x+ 25 /  (x² - x + 2)

The slant asymptote is the quotient i.e. x - 2

Hence, the slant asymptote of the function g(x) is x - 2

So, the discontinuities of g(x)

g(x) = (x³ -3x² -25 x -21) /  (x² - x + 2)

Set the denominator to 0

x² - x + 2 = 0

(x - 2)(x + 1) = 0

x= 2 or x= -1.

So, the discontinuities and their types are:

Essential discontinuity at x = 2

Removable discontinuity at x = -1

Answer:

For the function y = 3x - 1, the correct conclusion is C.As the value of x increases, the value of y increases.

As the value of x increases, the value of y increases.

In this function, y is dependent on the value of x. The variable x is multiplied by 3 and then subtracted by 1 to find the value of y. As the value of x increases, the value of y will also increase because it is being multiplied by 3.

For example, if x = 1, then y = 3(1) - 1 = 2. If x = 2, then y = 3(2) - 1 = 5. As you can see, as the value of x increases, the value of y also increases.

Therefore, the correct conclusion for this function is C. As the value of x increases, the value of y increases.

The smallest pair of 4-digit numbers such that the difference between them is 303 and their HCF is 101 are 1010 and 1313.

HCF (Highest Common Factor) of two numbers, which is the largest number that divides both numbers evenly.

Let's call the smaller of the two numbers "x". The larger number would be "x + 303".

The HCF of these two numbers must be 101, which means that 101 must be a factor of both x and x + 303.

To find the smallest possible value of x, we need to find the smallest number that is divisible by 101 and also a 4-digit number.

The smallest multiple of 101 that is a 4-digit number is

=> 101 x 10 = 1010.

Therefore, x = 1010.

The larger number would be

=> x + 303 = 1010 + 303 = 1313.

Answer:

Step-by-step explanation:

The pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

What is pressure ?

In physics, pressure is the amount of force applied per unit area. It is a scalar quantity, which means that it has a magnitude but no direction. Pressure is typically denoted by the symbol P, and its units are commonly expressed in pascals (Pa), which is the SI unit of pressure.

Pressure can be defined as the amount of force F applied per unit area A:

P = F / A

For example, if a force of 100 newtons (N) is applied to an area of 2 square meters (m^2), then the pressure would be:

P = 100 N / 2 m^2 = 50 Pa

Pressure is an important concept in many areas of physics, including fluid dynamics, thermodynamics, and atmospheric science. It is commonly used to describe the behavior of gases and liquids under different conditions, such as changes in temperature or volume. Pressure can also be used to calculate other physical properties, such as the flow rate of a fluid or the speed of sound in a gas.

According to given condition :

The rate of change of the fuel pressure in the fuel tank of the space shuttle is given by the derivative of the function [tex]r(t) = 17e^(-0.1t)[/tex]psi per second with respect to time t. Taking the derivative of r(t), we get:

[tex]r'(t) = (-0.1) * 17e^(-0.1t)[/tex]Simplifying this expression, we get:

[tex]r'(t) = -1.7e^(-0.1t)[/tex]

To find the rate at which the pressure is decreasing at t = 15 seconds, we substitute t = 15 into the expression for r'(t):

[tex]r'(15) = -1.7e^(-0.1*15)[/tex]

r'(15) ≈ -0.26 psi/s

Therefore, the pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

The required equation which intersects the points (12, -2) and (6, -8) in the point-slope form is y+2 = x-12.

The general form of a linear equation is y-y1=m(x-x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).

To understand more about it and see some instances, watch this video.

Both the slope-intercept form and the point-slope form can be used to write the equation of a straight line.

The slope and ANY point on the line are highlighted using the point-slope form.

Slope intercept form merely shows the slope and the y-intercept of a line.

So, we have:

m = 1

And points are (12, -2) and (6, -8)

We need to use the points: (12, -2)

Now, form the equation as follows:

y - (-2) = m (x-12)

y + 2 = 1(x-12)
