Answer:
x are 42 and 138degees
Step-by-step explanation:
Given the expression sin x = 0.6691
sin x = 0.6691
Take the sin inverse of both sides
sin⁻¹(sin x) = sin⁻¹(0.6691 )
x = sin⁻¹(0.6691 )
x = 41.99
x = 42 degrees (to the nearest degree)
Since sin theta is positive in the second quadrant;
x = 180 -theta
x = 180 - 42
x = 138degrees
Hence the value of x are 42 and 138degees
Answer:
(1, 0.5)
Step-by-step explanation:
From the graph attached,
x-values are representing the number of games downloaded,
y - values are representing the total cost.
Unit rate means rate of 1 game downloaded.
If we represent this in terms of coordinates,
x- value (game downloaded) = 1
y - value (price of one game download) = $0.5
Therefore, point (1, 0.5) will represent the unit rate.
Option (2) on the top row will be the answer.
The difference of 2.5 x 
- 1.5 x 10³ is 2.35 x .
<h3>What is the difference?</h3>
Difference is the result of the subtraction of two or more numbers. The numbers are written in scientific notation. Scientific notation is a method that is used to write large numbers.
The exponent of the numbers have different value. In order to evaluate them, they have to have the same values.
2.5 x - 1.5 x 10³
2.5 x - 0.15 x
2.35 x
