In radians:
To get 0, only one part of the multiplication needs to be zero for the whole thing to be zero. Thus we get 2 equations:
t=0, and cos(t)=0
for the first equation, it's pretty self-explanatory and sp we get 0 as one solution.
For the second equation, cos(pi/2) and cos(3pi/2) both equal 0 so both pi/2 and 3pi/2 are answers. Since there is no bound to this problem, the actual answer is:
(2Z+1)pi/2 and 0
(2Z+1) means all odd integers
Answer:
Your question is in what base please?
Answer:
x = 1, 3
Explanation:
Thus, there are two solutions and the values are <u>1</u> and <u>3</u>
A 5% raise means that you have to find out what 5% of 8 is and then add that to 8:
5/100 * 8 = 40/100 = $0.40
8 + 0.40 = $8.40.
