C is the right answer because the period should be pi/(1/3), so the answer is 3pi
Answer:
The answers are x < -65, x > 85, x < 180, x<= -13, and x >=25.
Step-by-step explanation:
For the first three, there's an open circle so the sign for the inequality would be < or > but for the last two, there's a closed circle so the sign for the inequality would be <= or >=, the ones with a line underneath. For 1, 3, and 4, the line goes to the left, showing that x is a number less than the point so it would have <, the less than sign. For 2 and 5, the line goes to the right, showing that x is a number greater than the point so it would have >, the greater than sign.
There's a trick to figuring out the right sign. If the line is pointing to the left, the inequality would be x < __, and the sign is pointng to the left. If the line is pointing to the right, the inequality would be x > __, and the sign is pointng to the right. This only works is x is on the left side of the inequality.
4/10 chance of rain Friday, 6/10 chance Saturday and 1/10 chance Sunday.
That means the chances of it not raining are 6/10 4/10 and 9/10
You multiply these together to get the chances of it not raining.
You get 216/1000 or .216 or 2.16% chance of it not raining
Answer:
3x+12=36
x=8
Step-by-step explanation:
3x+12=36
3x=36-12
3x=24
x=24/3
x=8
