We know that tanθ = sinθ/cosθ
For a number to be undefined, the denominator must equal to 0. At π/2, the cosθ value is 0 and sinθ is 1. Hence, tan(π/2) is undefined.
Hope I helped :)
Answer:
$150
Step-by-step explanation:
First use a proportion to find the answer:
40/100=60/x
Now we solve for x
60*100=6,000
6,000 divided by 40= 150
x=150
Therefore the answer is $150
Answer:
125.0272
Step-by-step explanation:
7 (1.14)^22
Each hour it grows 14%. This means after 1 hour, it has grown 7*1.14. After two hours 7*1.14 (1.14) or 7*(1.14)^2, etc so after 22 hours use equation above to solve.
Answer:
13.5 minutes
Step-by-step explanation:

Cross multiply
3 × 576 = 128x
3 × 576 = 1,728
1,728 = 128x
1,728 ÷ 128 = x
13.5 = x
