product is the answer to a multiplication problem mx6=90
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:
Step-by-step explanation:
2915 can stay as it is; 15.458 should be rounded down to 15. Then we have
2915-15, or 2900 (which is a very reasonable estimate).
C because 3.7 x 1/2 x 4.8= 8.88
Answer:
6 (8 + 2)
The sum means addition. Add 8 and 2. Multiply that entire thing by 6.
