The graph below plots a function f(x): 220 200 180 160 140 120 100 BO If x represents time, the average rate of charge of the function for in the first two seconds is___________.

Answer:

? = 77°

Step-by-step explanation:

the 3 angles in a triangle sum to 180° , that is

? + 35° + 68° = 180°

? + 103° = 180° ( subtract 103° from both sides )

? = 77°

Answer:77

Step-by-step explanation:

180-103=77

Answer:

\(3\frac{1}{5}\)brownies per hour

Step-by-step explanation:

     Given parameters:

Number of brownies = \(\frac{4}{5}\) of a dozen

Time taken  = 3hrs

Unknown:

Average baking per hour = ?

Solution:

The average baking per hour;

    This is a rate problem;

     Average baking per hour = \(\frac{number of baking}{time}\)

Number of brownies = \(\frac{4}{5}\) x 12  = \(\frac{48}{5}\)

 Average baking per hour = \(\frac{48}{\frac{5}{3} }\)  

                                            = \(\frac{48}{5} x \frac{1}{3}\)

                                             = \(\frac{16}{5}\)

                                            = 3\(\frac{1}{5}\)brownies per hour

Answer:

0.29    

Step-by-step explanation:

Knowing that the shaded angle is 106 degrees, and a circle's angle total is 360 degrees, we will know what fraction of the circle is shaded by dividing the shaded region's angle by the angle of an entire circle:

106/360 = 0.29              

The fraction of the circle that is shaded is also the probability that a randomly selected point within the circle falls in the shaded region since we just divided the desired outcome by all of the possible outcomes.

Answer:

35.4m below sea level

Step-by-step explanation:

172.5 - 137.1 = 35.4

The shark's location is now 35.4m below sea level.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

For example 4 -2 = 2

Using the arithmetic operations of addition and subtraction, the shark's location is now in relation to sea level if the shark begins 172.5 meters below sea level and then swam up 137.1 meters.

Assume that distance below sea level is positive,

⇒ 172.5 - 137.1 = 35.4

Hence, the shark's location is now 35.4m below sea level.

On solving the provided question we can say that As a result, the probability of a student P(x < 75) = 75 + (-75 ) =  0 .

Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% since there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many disciplines, including statistics, economics, science, and engineering.

z = (x - μ) / σ

z = (75 - 75) / 10 = 0

That is, a raw score of 75 equates to a z-score of 0.

P(z < 0) = 0.5

As a result, the likelihood of a student scoring less than 75% is 0 or 0%.

So, P(x < 75) = 75 + (-75 ) = 0

Smallest value first  is -3

To plot the curve of a cubic equation, we need cubic equation formula. This formula helps to find the roots of a cubic equation. If the degree of the polynomial is n, then there will be n number of roots. The roots of cubic equation are also called zeros.

 \(x^3-x^2-9x+9\)

First factorize the polynomial to get;

\(\Rightarrow x^2(x-1)-9(x-1)\)

\(\Rightarrow (x-1)(x^2-9)\)

\(\Rightarrow (x-1)(x+3)(x-3)\)                           \(\because a^2-b^2=(a+b)(a-b)\)

The marginal revenue is 909  dollars per unit.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

R(q) = -2q² + 1000q _____(1)

Where q is the unit sold.

Now,

Substitute q = 91 in (1).

R(q) = -2q² + 1000q

R(q) = -2 x 91² + 1000 x 91

R(q) = -8281 + 91000

R(q) = $82719

Now,

91 units = $82719

1 unit = 82719/91

1 unit = $909

Thus,

909 dollars per unit is the marginal revenue.

Answer:

ok will do

Step-by-step explanation:

a) To re-express the given differential equation as a first-order differential equation using matrix and vector notation, we can rewrite it in the form:

\(x' = Ax\)

where x is a vector and A is a square matrix.

b) To determine the stability of the system obtained in part (a), we need to analyze the eigenvalues of matrix A.

If all eigenvalues have negative real parts, the system is stable.

If at least one eigenvalue has a zero real part, the system is neutrally stable.

If at least one eigenvalue has a positive real part, the system is unstable.

c) To compute the eigenvalues and eigenvectors of matrix A, we solve the characteristic equation

\(det(A - \lambda I) = 0\),

where λ is the eigenvalue and I is the identity matrix.

By solving this equation, we obtain the eigenvalues.

Substituting each eigenvalue into the equation

\((A - \lambda I)v = 0\),

where v is the eigenvector, we can solve for the eigenvectors.

d) Once we have computed the eigenvalues and eigenvectors of matrix A, we can construct the diagonalization relationship as follows:

\(A = PDP^{(-1)}\)

where P is a matrix whose columns are the eigenvectors of A, and D is a diagonal matrix whose diagonal elements are the eigenvalues of A.

To show that this relationship is valid, we can compute \(PDP^{(-1)}\) and verify that it equals A.

The required shapes that describe the polygon;

Parallelogram, Quadrilateral, Rectangle, Rhombus.

A polygon with four sides and four angles is called a quadrilateral. When two pairs of parallel sides are equal in length, it is a parallelogram. If all four sides are equal in length, it is a rhombus. If all four angles are equal and equal to 90 degrees, it is a rectangle. If both conditions of equal sides and equal angles are met, it is a square. A trapezoid is a quadrilateral with exactly one pair of parallel sides.

In this case,

IJ || KL and JK || LI,

so it is a parallelogram.

Additionally,

since ZI≈ ZK and ZJ≈ ZL,

it can be concluded that the opposite sides are equal in length, making it either a rectangle or a rhombus.

Step-by-step explanation:

Linear Modeling

Some real-life events can be modeled as linear functions. If we are in a situation where a linear model is suitable, then we need two sample points to build the model and predict unknown behaviors.

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

\(\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\)

We are given the following points (H,A) where A is the altitude and P is the boiling point of a certain liquid: (8200,199.42) and (4700,206.07)

Applying the formula:

\(\displaystyle B-199.42=\frac{206.07-199.42}{4700-8200}(A-8200)\)

Calculating:

\(\displaystyle B-199.42=\frac{6.65}{-3500}(A-8200)\)

\(\displaystyle B-199.42=-0.0019(A-8200)\)

\(\displaystyle B-199.42=-0.0019A+15.58\)

\(\displaystyle B=-0.0019A+15.58+199.42\)

The equation is:

\(\displaystyle B=-0.0019A+215\)

Finally, we calculate the boiling point at A=2500 ft:

\displaystyle B=-0.0019*2500+215

B = 210.25°F

The boiling point of the liquid it 210.25°F

The number which is lesser than its square is 12/11

When a number is multiplied by itself, the result is a square number. For instance, 25 is a square number as it is composed of 5 lots of 5, or 5 × 5. 

The opposite of squaring an integer is finding its square root. The result of multiplying a number by itself yields its square value, whereas the square root of a number may be found by looking for a number that, when squared, yields the original value. It follows that a a = b if "a" is the square root of "b." Every integer has two square roots, one of a positive value and one of a negative value, because the square of any number is always a positive number. For instance, the square roots of 4 are both 2 and -2. However, the square root of a number is typically only expressed as the positive value.

9/10 , 12/11 , 15/16 and 13/13

Answer:

1

Step-by-step explanation:

Perpendicuar lines have slopes that are opposite reciprocals: 6 ==> -1/6

y=mx+b

y=-x/6 + b ==> plug in slope -1/6 into slope equation

1 = -6/6 + b ==> plug in x and y values into slope equation

1 = -1 + b

1 + 1 = -1 + 1 + b

b = 2 ==> solve for b

y = -x/6 + 2 ==> plug in the value of b into the equation

y - 1 = -x/6 + 2 - 1

y - 1 = -x/6 + 1

y - 1 = -(x/6-1) ==> answer: 1
