Cos^2(81°) - sin^2(81°)
Answer:
= (162°)
Step-by-step explanation:
(81°) - (81°)
we know that;
(x°) - (x°) = (2x°)
(81°) - (81°) = (2 * 81°)
= (162°)
Answer: The required equation is
Step-by-step explanation: Given that a plants height is 1.6 times its age.
We are to write an equation for the situation, where h is the plants height and y is the plants age.
The given situation can be written in equation form as follows :
Thus, the required equation is
–6.2, 5.71, –3.96, 2.84
