Answer:
BA
CB
CA
Step-by-step explanation:
this simply means that such a letter combination stands for a line that goes through the points with these letters.
and a "ray" means a straight line (not one that goes around a corner). "from this figure" means lines (or connections between points) that are drawn in this graphic.
BA yes
B is just a point, no line. therefore, no.
DBA guys around a corner (from D to B, and then from there to A). therefore, no.
AD would be a straight line, but it is not drawn in the graphic. therefore, no.
ADB is partly not drawn, and it goes around a corner. therefore, no.
CB, CA are both straight lines in the graphic. yes.
Answer: +3
Step-by-step explanation: The answer is positive 3 because if you look on a number line, you will only move 3 spaces to the right. You could also look as this problem as a subtraction problem. 5-2=3. Tip: While adding positive and negative numbers, look at the bigger number in the problem. In this case it's 5. The five is positive so the answer is positive. If the five were to be negative, the answer would be negative. In adding the larger number dictates whether the sum will be positive or negative.
Really, you just need to find out how many ways 14 can be divided. It can be divided into 7 groups of 2, or 2 groups of 7.
We are given with 90<x<180 degrees and asks for the value of sin(x/2), cos(x/2) and tan(x/2). We just substitute the maximum and minimum angle to the equations. sin (180/2) is equal to 1 and sin (90/2) is equal to
to 1. cos (x/2) is equal to 0≤y≤<span>
. tan (x/2) is equal to 1 to infinity. </span>
