Answer:
Step-by-step explanation:
in quadrant 1 cos and sec are positive.
cos(θ)=√(1-sin²θ)=√(1-(12/13)²)=√((169-144)/13²)=5/13
secθ=13/5
Answer:
A will get 9, B will get 12 and C will get15 chocolates
:-)
3x10 equals 30. The .4 is in the tenths place so multiplied by 10 will move it to the ones place.
Answer:
- Function: B
- Not a function: A, C
Step-by-step explanation:
A relation is a function if there is only one y-value for each x-value. If you can draw a vertical line on the graph that intersect more than one point, the relation is not a function. (This is the "vertical line test.")
<h3>Application</h3>
Graph A: there are 3 y-values associated with x=2. Not a function.
Graph B: passes the vertical line test: A function.
Graph C: there are 2 y-values at each of x=1 and x=2. Not a function.
