Answer:
f(x) = sec x. tan x
⇔ f(x) = 1/cosx . cosx/sinx
⇔ f(x) = sin x
+) when f(x) is increasing => sin x increases
=> x will increase
+) f(x) is decreasing => x will decrease
+) f(x) is concave up => x ∈ (-pi/2; 0)
+) f(x) concave down => x ∈ (0; pi/2)

Step-by-step explanation: less than because 60 + 90 = 150 and you said 1 hour plus 1 hour and a half so your answer is more than because 150 is more than 100
Answer:
60
Step-by-step explanation:
the question is based on similarity and enlargement
firt thing put the velues to ratio form;8;20
simplify to obtain2:5 as your linear scale factor...
if 5:150
2=?
2*150/5=60
