Answer:
school day
Step-by-step explanation:
When drawing a chart or a graph:
- x-axis: Independent variable
- y-axis: Dependent variable
The two given variables are:
- number of students who wear blue shirts
- days of the week
Therefore, in this scenario the <u>independent variable</u> is the <u>school day</u> and the <u>dependent variable</u> is the <u>number of students</u> since the former effects the latter.
So the data on the horizontal axis (x-axis) is: school day
The answer is C.
To solve these types of equations you first need to make sure that you equation is equal to 0. In this case all of the numbers are already on the same side so no work needs to be done there. Then we can get a, b and c values for the quadratic equation by looking at the coefficients.
a = 4 (number attached to x^2)
b = -6 (number attached to x)
c = 1 (number with no variable attached)
Now we can put this into the quadratic equation.


First term, n=1: 2*1 -3 = -1
Second term, n=2: 2*2 -3 = 1
Third term, n=3: 2*3 -3 = 3
Answer: 22.1°
Step-by-step explanation:
Applying law of sines, we have:
8² = 19² + 14² - 2*14*19 * Cos(x)
64 = 557 - 532*cos(x)
64 - 557 = -532*cos(x)
-493 = -532*cos(x)
Divide both sides by -532
-493/-532 = cos x
0.926691729 = cos x
x = cos^-1(0.926691729)
x = 22.1° (nearest tenth)
