Answer:</h3><h3>cos(-t) = -4/9</h3><h3>sec(-t) = -9/4</h3>
Explanation:
Since cosine is an even function, we can say cos(-t) = cos(t) for all values of t. So this explains why cos(-t) = cos(t) = -4/9. No change happens.
To find the secant value, we apply the reciprocal. This is because sec = 1/cos. So that's how -4/9 flips to -9/4.

Answer:
No, It is not true
Step-by-step explanation:
First of all, we should have a number in the tenths place, and we don't.
Also, in the hundredths place, we should have 9, not 4.
And finally, the answers should be 0.195, not 0.042.
