CosP=sinQ
cosQ=sinP
Thus cosP=4/5 and cosQ=3/5 so the sum is 7/5
Answer:
see explanation
Step-by-step explanation:
Given that t and w vary inversely then the equation relating them is
t =
← k is the constant of variation
To find k use the condition t =
when w = 4
k = tw =
× 4 = 
t =
← equation of variation
When w = 9, then
t =
= 
4. Yes because a function is a expression, rule, or law that defines a relationship between one variable and another variable which is what is happening in this image
5. Yes the slope is shown on the graph because it shows the measure of its steepness which can be determined by simply looking at the image
6,4 and or 8,7 should be the answer
