Answer:
0
Step-by-step explanation:
cos(60) = ½
sec(60) = 2
sin(30) = ½
cosec(30) = 2
sin(0) = 0
2 - 2 - 0 = 0
Answer:
<u>18</u>
Step-by-step explanation:
<em>replace a with -2</em>
-4(-2) + 10
<em>multiply the -4 and the -2, the negatives cancel out and leave you with 8</em>
8 +10
<em>just add</em>
18
The answer is 350.
<em>
m= minutes</em>
Plan 1: 9+0.13<em>m</em>
Plan 2: 23+0.09<em>m</em>
9+0.13<em>m</em> = 23+0.09<em>m</em>
-9 -9
0.13<em>m</em> = 14+0.09<em>m</em>
-0.09<em>m</em> -0.09<em>m</em>
0.04<em>m</em>= 14
14÷0.04= 350
<em>m</em>= 350
F/3+36=c subtract 36 from both sides
f/3=c-36 multiply both sides by 3
f=3c-108
