Tan^2 x - Tan^ x sin^2 x
= tan^2x ( 1 - sin^2 x)
= tan^2 x * cos^x
= sin^2 x * cos^2 x
----------------------
cos^2 x
= sin^2 x
Answer:
0.00067969413
Step-by-step explanation:
(a) 1 1/2 cups + 3/4 cup + 1/8 cup = 1 4/8 + 6/8 + 1/8 = 2 3/8 cups
(b) 3-cup mixing bowl because there is a total of 2 3/8 cups, which is greater than 2 but less than 3.
Move the decimal five places until it is after one number, and because the number got bigger, your exponent is a negative.
3:5 ratio mean there are 8 "parts" (3 + 5 = 8)
The distance between the x-coordinates is |-3 - 5| = 8.
So each "part" is 8/8 = 1 unit long in the x-direction.
You want I to be 3(1) = 3 units from D, so the x-coordinate of I is -3 + 3 = 0.
Same deal for y.
|2 - 5| = 3 is the distance between D and E
Each part is 3/8.
3(3/8) = 9/8
2 + 9/8 = 25/8
So the point I is (0, 25/8)
