Solve the equation
(1/2)-sinx=1
Answers
Answer: #2. sin x (sin x + 1) = 0
sin x = 0 or sin x + 1 = 0
sin x = 0 or sin x = -1
Step-by-step explanation:
the value of x will be x = 210° and 330° for the given expression (1/2)-sinx=1.
What is an expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given a equation (1/2)- sin x = 1
Simplifying the given expression
=> (1/2)- sin x = 1
subtract 1/2 on both sides
=> -sin x = 1/2
=> sin x = -1/2
=> x = 210° and 330°
For all x = 0 to 360°

Step-by-step explanation:
Let ∠XYZ be x°.
Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.
[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]
To find the value of x°, take the inverse of cosine.
[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]
Thus, ∠XYZ= 66.4°

The product of two positive numbers is always greater than either number
Answers
The product of two positive numbers is always greater than either number the statement is false.
What are numbers?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.
Given that the product of two positive numbers is always greater than either number.
To understand this let's take an example take two numbers and multiply them.
2 x 5 = 10
Then take 2 and 0.5 and multiply them.
2 x 0.5 = 1
Here the result of the product is 1 which is less than 2. Therefore, if the product of two positive numbers is always greater than either number the statement is false.

After 4 minutes of reading, Aaron was on page 14 of his book. After 8 minutes he was on page 20. Which equation models the page number, y, in terms of minutes x?
Group of answer choices
y = 8x + 1.5
y = 1.5x + 8
y = −1.5x + 8
y = –8x + 1.5
Answers
Answer:
The answer would be (B) y = 1.5x + 8
Step-by-step explanation:
The equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Aaron who is reading a book. After 4 minutes of reading, Aaron was on page 14 of his book and after 8 minutes he was on page 20.
Now -
(x) represents the number of minutes and (y) is the number of pages.
At x = 4, y = 14
At x = 8, y = 20
The slope of the line will be -
m = (20 - 14)/(8 - 4)
m = 6/4
m = 3/2
The general equation can be written as -
y = 3x/2 + c
20 = 3/2 x 8 + c
20 = 12 + c
c = 8
Now, we can write the equation as -
y = 1.5x + 8
Therefore, the equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.
