Answer 1

A rational number is a number that can be expressed as a ratio of two integers. Integers can be positive or negative. Rational numbers are simply fractions. For example;

-5/2, -1/5, 3/1, 4/5 etc are all rational numbers because we can write them as a ratio of two integers.

Since some of this fractions can lead to both negativa and positive integers, hence rational number is a positive or negative whole number including 0.

Hence all the options are correct since rational numbers are are also repeating decimals

The general solution of the function, y = sin(x), can be found by using the measure of the angles that have sines which equals 0 as follows;

x = -(2•π•n - π) and x = 2•π•n

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

2•sin(x) = 0

Therefore;

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.

From the graph of the function, we have that the graph crosses the x–axis at points -π, 0, π, ..., which are multiples of π

The general solution to the function f(x) = sin(x) is therefore;

x = -(2•π•n - π) and x = 2•π•n

The price of sweaters starts at Pa= $120 each and a quantity supplied of Qa= 40 sweaters. If the price falls to Pb= $12 each, what is the new quantity supplied (Qb) if the slope of the supply curve is m=3 Round your answer to nearest whole number of sweaters.

Answers

The quantity of the new sweaters at a price of $12 is gotten using the slope of 3 to be 36 sweaters

How to find the new quantity if the price falls to $12

given data

Pa = $120

Qa = 40

Pb = $12

slope of the supply curve is m=3

The slope represents the relationship between the the input variable and the output variable.

The input variable is the price while the output variable is the quantity supplied.

The slope is the factor that multiplies the input to get the output, we therefore solves as follows

= Pb * slope

= $12 * 3

= 36

The maximum height reached by the ball is 22 feet

The ball stayed in the air for 1 second

What is a function?

A function can be defined as a rule, law or expression that shows the relationship between two identifiable variables:

The  independent  variableThe dependent variable

Given the function:

h(t) = -16t² + 32t + 6

Where;

h is the maximum height measured in feett is the time in seconds

To determine the maximum height in feet that the ball reached, we would be required to substitute the value of t as 1

We have:

h(1) = -16(1)² + 32(1) + 6

expand the bracket

h(1) = -16 + 32 + 6

Add the values

h(t) = 22 feet

To determine the time, we have;

-16t² + 32t + 6 = 22

-16t² +32t + 6 - 22 = 0

Add like terms

-16t² +32t - 16 = 0

Factorize further

-16t² + 16t + 16t - 16 = 0

Factorize in pairs

16t( t - 1) + 16 ( t - 1) = 0

Then,

t - 1 = 0

t = 1 second

Thus, the maximum height is 22 feet

Answers

Sheila's mapping diagram doesn't represent a function because it includes the points (3, 6) and (3, 6) and fails the vertical line test.

What is a mapping diagram?

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. Her relation has the following ordered pairs: (1, 1), (2, 2), (3, 3), (3, 6), (4, 4), 5, 5), and (6, 6). Since both (3, 3) and (3, 6) have the same x-coordinate, the relation fails the vertical line test and is not a function.

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.

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.

Answers

Answer: 23+42=42+23

We have rewritten 23 + 42 = 65 as 23 + 42 = 65 using the Commutative Law of Addition.

What is Number system?

A number system is defined as a system of writing to express numbers.

The Commutative Law of Addition states that changing the order of the addends does not change the sum.

a+b=b+a

Therefore, we can rewrite 23 + 42 as 42 + 23, and the equation becomes:

42 + 23 = 65

or 42+23=23+42

So, we have rewritten 23 + 42 = 65 using the Commutative Law of Addition.

Hence,  we have rewritten 23 + 42 = 65 as 23 + 42 = 65 using the Commutative Law of Addition.

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.
