Solve for x on [0, 2pi]
secx-cscx=0
I know what the answer is but can someone help me with the process of finding it?
Answers
The required solution to the trigonometry equation is x = π/4 + π n.
The equation of trigonometry functions is given in the question as
secx - cscx = 0
We have to determine the solution to the given equation
As per the question, we have
⇒ secx - cscx = 0
⇒ 1/cosx - 1/sinx = 0
⇒ (-cosx + sinx)/cosxsinx = 0
Using property : f(x)/g(x) = 0 ⇒ f(x) = 0
⇒ -cosx + sinx = 0
Divided by cosx into the equation,
⇒ -1 + tanx = 0
⇒ tanx = 1
The general solution for tan tanx = 1 is
⇒ x = π/4 + π n

What is the angle?
Angles are an integral facet in the study of mathematics, particularly geometry. Angles are formed by two rays (or lines) that begin at the same point or share the same endpoint. The point at which the two rays meet (intersect) is called the vertex.
Let us assume the angle name [tex]x[/tex] and the triangle [tex]ABC[/tex], and the hypotenuse is [tex]y[/tex].
Here given angle and side are
[tex]x=30[/tex] degree
And the side [tex]AB=23[/tex]
Now we are applying the [tex]sine[/tex] because it is

If $a$, $b$, $c$, and $d$ are four different digits from $1$ to $9$, inclusive, then what's the largest possible value for the decimal $a. B + c. D$ ?.
Answers
The largest possible value for the decimal $a. B + c. D$ us:
9.7 + 8.6 which results to 18.3.
Given that a, b, c, and d are different numbers (from 1 to 9), we are to find the largest possible value of a.b + c.d.
This problem can be answered by trial and error and with some logic. Clearly, a to d cannot be at the lower end of the values (1 to 5). Since the digits must be different, it can be a combination of digits from 6 to 9.
It is rather tempting to say that the 9.8 + 7.6 would yield the highest possible sum (=17.4) but this is incorrect. Since it is the sum of two numbers with a decimal, we have to maximize on the ones digit first before maximizing the tenths digit. Therefore: the combination of numbers must then be:
9.7 + 8.6 which results to 18.3
9.6 + 8.7 yields 18.3 as well.
Hence we get the required answer,

Kari's renter's insurance is set to increase by 10% per month after she files a theft claim. If her premium is $35 per month, what
will her new premium be?
$45 per month
$31.50 per month
$38 per month
$38.50 per month
Answers
Answer: $38.50 per month
Step-by-step explanation: We have to find 10% of 35 and add it to 35. This is because 10% of 35 is the amount that will increase so adding that to the original 35 will be her new premium. 10% of 35 is $3.50 and $3.50 + $35 is $38.50. This means her new premium is $38.50 per month.
Does the point (-7, 5) satisfy the inequality y > -3/7x +2
Answers
Answer:
Yes, the point (-7, 5) satisfies the inequality y > -3/7x + 2
Step-by-step explanation:
Plug in the values to the inequality and verify if it is true:
x = -7, y = 5
5 > (-3/7*-7) + 2
5 > (-3/-49) + 2
5 > 3/49 + 2
5 > 101/49
The inequality above is true (5 is greater than 101/49 [101/49 is about 2.06]), so the point (-7, 5) satisfies y > -3/7x + 2

Answers
The percentage of water in the milk cup and the percentage of milk in the water cup are same.
What is milk?
A white liquid meal called milk is generated by mammals' mammary glands. Before they can digest solid food, it is the main source of nutrition for young mammals. Milk immunity is influenced by immune components and immune-modulating elements.
Given:
There are a cup of milk and a cup of water.
Take one teaspoon of milk, put into the water cup; mix well.
Take one teaspoon of the mixture in the water cup and put into the milk cup then mix well.
Suppose the percentage of water cup are 'p' and the percentage of milk cup are 'q'.
When we add one teaspoon of milk and put into water cup then the percentage of water cup are 'p + 1'.
And the percentage of milk cup are 'q - 1'.
Again one teaspoon of mixture in the water cup put into the milk cup.
So, the percentage of milk cup are, q - 1 + 1 = q.
And the percentage of water cup are p + 1 - 1 = p.
The percentage will be same for both milk cup and water cup.
Hence, the percentage of water in the milk cup and the percentage of milk in the water cup are same.

Answers
The acceleration of the truck when it has a mass of 5000 kg and the truck driver presses on the brakes is 1.2m/s².
What is acceleration?The rate of change of an object's velocity with respect to time is defined as acceleration. Vector quantities are accelerations.
The orientation of an object's acceleration is determined by the orientation of the net force acting on that object's acceleration, which is the rate at which velocity changes over time in terms of both speed and direction. A point or object moving in a straight line is accelerated if it accelerates or decelerates.

Answers
The mean service time from the customers are between 161.5 to 164.7 seconds.
The trade magazine QSR routinely checks the drive-through service times of fast-food restaurants.
A 90% confidence interval that results from examining 607 customers in Taco Bell's drive-through has a lower bound of 161.5 seconds and an upper bound of 164.7 seconds.
Let's denote the mean service time by μ. Then, note that, we are given that n=607. Also, we are said that a 90% CI for μ is given by
(161.5,164.7)
This implies that we are 90% confident that μ lies in the interval. Or to be precise, this interval is a realization of a random interval that has 90% probability of covering the true mean. Thus, we are 90% confident that the mean service times of the restaurants are between 161.5 to 164.7 seconds.

With the help of unitary method , we can say that ,To create a batch of 15%-pigment paint, he needs to mix 98.57 liters of the 27%-pigment paint with the 12%-pigment paint.
What is unitary method ?Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.
Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.
Imagine that your square is made up of smaller unit squares.
The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.
To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.
According to our question-
Paint volume times pigment concentration equals pigment amount.
or
V × c = P
If the three options are referred to as 1, 2, and 3, then
P₁ + P₂ = P₃
V1c1 = V2c2 + V3c3

Step-by-step explanation:
The total volume of the ice cream in and on top of the cone is (16/3)πd³.
What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3 πr²h.
We have,
Volume of the hemisphere = 4 in³
The volume of ice cream.
= Volume of the hemisphere + Volume of the cone
= 4 + (1/3)π(d/2)²h
[ height = diameter ]
= 4 + (1/3) x π x d²/4 x d
= 4 + (1/3) x π x d³/4
= 4 + (4/3)πd³
= (16/3)πd³

Answers
The confidence interval for a proportion should be constructed since the variable of interest is a person's opinion, which is a qualitative variable.
What is a qualitative variable?A trait that cannot be quantified is referred to as a categorical variable (also known as a qualitative variable).
Nominal or ordinal categorical variables are also acceptable.
Since the variable of interest is a person's opinion, which is a qualitative variable, the confidence interval for a proportion should be built.
Statistical Variables Qualitative variables also referred to as categorical variables are variables without a built-in sense of hierarchy.
As a result, they are quantified using a nominal scale.
For instance, a qualitative variable is a name as well as hair color (Black, Brown, Gray, Red, Yellow).

Answers
For the two lines to be parallel, the value of n must be 3
How are two lines parallel in a coordinate?When two straight lines are plotted on the coordinate plane, we can tell if they are parallel from the slope, of each line. If the slopes are the same then the lines are parallel.
The slope of each line is calculated as (y2-y1)/x2-x1
for line AB, the slope = (6n-n)/10-4 = 5n/6
for line CD, the slope= 8n-(-6)/9-(-3)=( 8n+6)/12
for AB and CD to be parallel,
5n/6 = (8n+6)/12
multiply both sides by 12
10n= 8n+6
