Answer:
tan²A
Step-by-step explanation:
1+tan²A/1+cot²A Simplify 1+tan²A first
sec²A/1+cot²A Now simplify 1+cot²A
sec²A/csc²A Simplify sec²A and csc²A
/
Simplify the fraction
sin²A/cos²A = tan²A

1. No it is not because it is false. It is false because for it to be three times as many wins as jim, jim would need around 166 or less wins to make cy have three times the wins. 2. i believe the graph is misleading because there isnt enough pets on the graph or data on the graph. 3. i honestly dont quite understand the question i would need to see it in person. Hope the first two answers help you out :-)
<span>Krystal's rate = 1 floor in 16 min. = 1/16 floors per min.
Working together their rate = 1 floor in 5.76 min. = 1/5.76 floors per min.
We need to determine Perry's rate, so we need to equate their combined rate with the sum of the individual rates.
Let Perry's time = x
In equation form, we can write:
1/16 + 1/x = 1/5.76
Solve for x:
(x+16)/16x = 1/5.76 -> 5.76(x+16) = 16x -> 10.24x = 92.16 -> x = 9
So, Perry would take 9 mins. to do the floor alone.
I hope this helped!
