Answer:
-x^2-15xy-50y^2+14y
Step-by-step explanation:
We have to find 100% of the number. We can use proportion to get it
3% -----------1.5m
100% -------- x
crossmultiply now
3*x=1.5*100
3x=150 /:3 divide both sides by 3
x=50m
2. Similar situation
40% ------------1000
100% -----------x
crossmultiply
40*x=100*1000
40x=100000 /:40
x=2500 - its the answer
Step-by-step explanation:
=(1+ sin^2 A/cos^2 A).cos^2 A
=[(cos^2 a+sin^2 a)/cos^2 a].cos^2 A
=[1/cos^2 a] . cos^2 a
=1
