Answer:
when n=0, x=18°
when n=1, x= 90°
when n=2 x=18+72*2=162°
when n=3, x=18+72*3=234°
when n=4, x=18+72*4=306°
or
x= 18 + 72n, when n={0,1,2,3,4}
Step-by-step explanation:
4sin(5x) =4
sin(5x) = 1
sin(α) = 1, when α=90° + 360n
5x = 90° +360n
x= 18 + 72n
when n=0, x=18°
when n=1, x= 90°
when n=2 x=18+72*2=162°
when n=3, x=18+72*3=234°
when n=4, x=18+72*4=306°
when n=5, x°=18+72*5 = 378°
General answer : x= 18 + 72n, when n={0,1,2,3,4}
Answer:
b. 56
Step-by-step explanation:
Please consider the complete question.
There are 8 members on a board of directors. If they must form a subcommittee of 3 members, how many different subcommittees are possible?
We will use combinations for solve our given problem.
, where,
n = Number of total items,
r = Items being chosen at a time.
For our given scenario 
and 
.
Therefore, 56 different subcommittees are possible and option 'b' is the correct choice.
Answer:
6
Step-by-step explanation:
if 67004 is rounded off to nearest ten thousand the answer is 70000
so missing digit = 6
Answer:
y = 2/3 x -2
Step-by-step explanation:
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
We need to solve for y
2x-3y = 6
Subtract 2x from each side
2x-2x-3y=-2x+6
-3y = -2x+6
Divide by -3
-3y/-3 = -2/-3x+6 /-3
y = 2/3 x -2
The slope is 2/3 and the y intercept is -2
