Answer 1

The values of the trigonometry formulas are sin(240) = -sin(60), cos(225) = -cos(45) and tan(225) = tan(45)

How to determine the values of the trigonometry formulas?

The trigonometry ratios are given as

sin(180 - ∅) = sin(∅)

cos(180 - ∅) = -cos(∅)

tan(180 - ∅) = -tan(∅)

Also, we have the following trigonometry ratios are given as

sin(180 + ∅) = -sin(∅)

cos(180 + ∅) = -cos(∅)

tan(180 + ∅) = tan(∅)

Using the above trigonometry ratios, we  have

sin(240) = sin(180 + 60)

By comparison, we have

sin(240) = sin(180 + 60)

sin(180 + ∅) = -sin(∅)

This gives

∅ = 60

So, we have

sin(180 + 60) = -sin(60)

Evaluate

sin(240) = -sin(60)

Using the above trigonometry ratios, we  have

cos(225) = cos(180 + 45)

By comparison, we have

cos(225) = cos(180 + 45)

cos(180 + ∅) = -cos(∅)

This gives

∅ = 45

So, we have

cos(180 + 45) = -cos(45)

Evaluate

cos(225) = -cos(45)

Using the above trigonometry ratios, we  have

tan(225) = tan(180 + 45)

By comparison, we have

tan(225) = tan(180 + 45)

tan(180 + ∅) = tan(∅)

This gives

∅ = 45

So, we have

tan(180 + 45) = tan(45)

Evaluate

tan(225) = tan(45)

Hence, the value is tan(225) = tan(45)

What is continuous function ?

A continuous function is one whose graph is continuous throughout without any interruptions or leaps, as the name suggests. In other words, we claim that a function is continuous if we are able to draw its curve (graph) without ever picking up the pencil. Calculus students must learn about a function's continuity because without it, a function cannot be differentiable.

Table

An x-intercept results whenever the function crosses the x-axis and changes sign. Additionally, when the function's value is zero, it acts as an x-intercept.

In the tables, there are two sign changes (from +4 to -3 and from -3 to +2). It also has one value of zero, and this function has a minimum of three x-intercepts. Therefore, you can infer that the choid b is accurate.

The function has more than one x-intecept.

Answer:

815/99 (fraction); 8 23/99 (mixed number)

Step-by-step explanation:

the fraction for 0.23 repeating is 23/99

you add 8 in front of it

8 23/99 is the mixed number version

for the fraction version you must multiply 99 to 8 and then add it to 23

8 * 99 = 792

792 + 23 = 815

The quadratic equation is of the form y = ax² + bx + c

In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree just 2, or simply known as a quadratic.

x is the only variable. A parabola with its axis of symmetry parallel to the y-axis represents the graph of a univariate quadratic function, as seen to the right.A quadratic equation is produced if the quadratic function is set to zero. The roots of an univariate function are the solutions to the univariate equation.When authors speak to a quadratic polynomial, they may mean "having degree exactly 2" or "having degree at most 2". If the degree is less than 2, this scenario may be referred to as a "degenerate case." Which of the two is intended will typically depend on the context.In some circumstances, like in the instance of a second-order polynomial, the word "order" is used to denote "degree." The word "degree of a polynomial" refers to the highest degree of a non-zero term in a polynomial, whereas the term "order" typically refers to the lowest degree of a non-zero term in a power series.

What is a general solution of a function?

A general solution of a trigonometric function gives all possible solutions of the trigonometric functions and comprises of the integer n.

The given function is presented as follows;

f(x) = 2•sin(x)

The solution of the function is given by the point where f(x) = 0 as follows;

When f(x) = 0

sin(x) = 0

Therefore;

x = arcsin(0)

sin(2•π) = 0

sin(π) = 0

Therefore, the solution is the set of whole number multiples of pi

Which gives;

x = -(2•π•n - π) and x = 2•π•n

Please find attached the graph of the function created with the required application.

The water pressure on a submerged object is given by P = 64d, where P is the pressure in pounds per square foot, and d is the depth of the object in feet.
a. solve the formula for d.


b. Find the depth of a submerged object if the pressure is 672 pounds per square foot.

Answers

The water pressure on the submerged object is given by d = P ÷ 64

Pressure is the force that is applied perpendicularly to the area across which it is applied to an object's surface (symbol: p or P).

Gauge pressure, frequently written gage pressure, is the measurement of pressure in proportion to the atmosphere.

Various units are used to express pressure.

The pound-force per square inch (psi), which is equivalent to one newton per square meter (N/m2) in the SI, is the standard unit of pressure in the imperial and American customary systems.

A unit of force is divided by a unit of area to arrive at some of these findings.

a. The given formula is is P=64d

or , d = P ÷ 64

b. at a pressure of 672

d = 672  ÷ 64

or, d = 10.5 feet

Therefore the pressure is 672 pounds per square foot at a depth of 10.5 feet.

Matrices can be used for a variety of operations, including addition, multiplication, transposition, and scalar multiplication. When executing these matrix operations, certain guidelines must be followed. For example, matrices can be added to or subtracted from if only their rows and columns are the same, whereas they can be multiplied if only their first and second sets of columns are exactly the same.

An illustration of two circles that depicts the relationship between input and output values is known as a mapping diagram. By drawing an arrow from one x-value to its corresponding y-value, the x-values (inputs) in the image are transferred to the y-values (outputs).

It does not represent a function because the same input value, 3, is mapped to more than one output value, 3 and 6.
