The answer is C when you plug in 75 for n you get 75/4+37 which equals 55.75 when rounded to the nearest whole number it is 56 which is C. Hope that helps
We can rewrite this by subtracting the right side to get
... 3^(-x) -x^3 -x = 0
A graphing calculator shows this to have a solution near x=0.5.
_____
There are no algebraic means for solving such a combination of exponential and polynomial functions.
Answer:
See below.
Step-by-step explanation:
When x has a value between 0 and 90 the values of sin x ranges from 0, if x = 0 and 1 , if x = 90 degrees.
The cosine of x has the reverse value: cos x is 1 for x = 0 and 0 for x = 90 degrees.
At x = 45 the sine and cosine are equal in value.
So for sin x < cos x the value of x must be between 0 and 45 degrees.
So a possible value of x is 30 degrees.
When x = 30 sin x = 0.5 and cos x = 0.866.
Answer:
7 games
Step-by-step explanation:
Ricardo has 2 cases with x number of games in each. This means 2x is the amount of video games in both. He gives away 4. He now has 2x-4 and has 10 left. This is 2x-4=10. Solve for x.
2x - 4 = 10
2x = 14
x=7
