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•nWhat 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 independent variableThe dependent variableGiven the function:
h(t) = -16t² + 32t + 6
Where;
h is the maximum height measured in feett is the time in secondsTo 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,

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).

Her relation has the following ordered pairs: (1, 1), (2, 2), (3, 3), (3, 6), (4, 4), 5, 5), and (6, 6).

Step-by-step explanation:
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.
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.

What is the value of the estimated standard error for the following set of D-scores?
Scores: 4, 8, 4, 4
-2
-4
-12
-1
The value of the estimated standard error for the following set of D scores 4, 8, 4, 4 is 1.
The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is the statistic's standard error. The term "standard error of the mean" is used when referring to a statistic that is the sample mean.
Consider the following set of D scores,
4, 8, 4, 4
We will calculate ∑D and ∑D² to find the SS for the D scores.
Therefore,
∑D = 4 + 8 + 4 + 4
∑D = 20
∑D² = 4² + 8² + 4² + 4²
∑D² = 16 + 64 + 16 + 16
∑D² = 112
Now, the formula for the standard score is given as:
[tex]SS=\sum D^2- \frac{(\sum)^2}{n}[/tex]
SS = 112 - [ (20)² /4 ]
SS = 112 - 100
SS = 12
Now,
[tex]S_{D}=\sqrt{\frac{SS}{n-1} }[/tex]
[tex]S_{D}=\sqrt{\frac{12}{4-1} }[/tex]
[tex]S_{D}=\sqrt{4}\\ S_{D}=2[/tex]
[tex]S_{\overline D}=\frac{S_{D}}{\sqrt{n} }[/tex]
[tex]S_{\overline D}=\frac{2}{\sqrt{4} }[/tex]

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.

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.
