f 25%, two hour-exams that together contribute 25% and a final exam that contributes 50%. There are 100 possible points for the laboratory, 50 possible points for each hour exam and 100 possible points for the final. A student in the course got 75 points for the laboratory, 40 and 38 points for the two hour exams and 85 points for the final. use weighted mean to determine his overall score (from 0 to 100) for the course

Answer:

x2 =  -0.600000

x3 = -0.521600

Step-by-step explanation:

Given the formula;

xn+1 = (xn)³-5/10

x2 = (x1)³-5/10

Given x1 = -1

x2 = (-1)³-5/10

x2 = (-1-5)/10

x2 = -6/10

x2 = -0.600000

x3 = (x3)³-5/10

Given x3 = -0.6

x3 = (-0.6)³-5/10

x3 = (-0.216-5)/10

x3 = -5.216/10

x3 = -0.521600

Select the correct answer. Which of the following is a solution to 4sin2x − 1 = 0? A. 30° B. 60° C. 90° D. 120°
vesna_86 [32]

Answer:

The correct option is A.

Step-by-step explanation:

The correct form is:

4sin^2 x − 1 = 0

First step is add 1 to both sides:

4sin^2 x-1+1=0+1

4sin^2 x=1

Now to eliminate 4 divide both sides by 4

4sin^2 x/4=1/4

sin^2 x=1/4

Take square root at both sides

√sin^2 x = √1/4

sinx = 1/2

Thus the correct option is 30° ....
