15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
Answer:
A&C
Step-by-step explanation:
As, you said, the first answer is C. Now, we are given seven, and when we are adding a negative number, we move in the direction of left, and since we are moving by 7, we would be moving 7 to the left. Therefore, the other answer is A.
Answer:
x = -1 + 2 sqr2
or
x = -1 -2 sqr2
Step-by-step explanation:
So this... is a slightly complicated problem you have to set up an equation.... so 7x-12=2x+8 you subtract 2x and add 12 to both side so now you have 5x=20 now divide both sides by 5 now you have x= 4 so plug it into the problems for the sides 2(4)+8= 14 is the length of one side and 7(4)-12=16 so 16 is the length for the other now you just pick the measurement to use hope this helped!!!!! have an amazing day!
