Sec theta = 1/cos theta = 1/0.5 = 2
Option D is the correct answer.
Interest = Pin = principal * interest rate * number of years
Let interest rate be i, then
600*i*2+150*i*4=90
1200i+600i = 90
i=90/(1200+600)=90/1800=1/20=0.05 or 5%
Answer:
Step-by-step explanation:
Use the exponential form of this log equation. Rewriting this into exponential form gives us

5-squared is 25, so
25 = 2x - 3 and
22 = 2x so
x = 11
Answer:
270 ÷ 30 = 9
Step-by-step explanation:
9x3=27
90x3 = 270
27 ÷ 3 = 9
270 ÷ 30 = 9
90 x 3 = 270
30 x 9 = 270
