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
capacity of the stadium=23564
no.of seats occupied=3/4 of 23564
no.of people in the stadium=23564*3/4
=17673
Answer:70
Step-by-step explanation:
You multiply all three numbers.
Just plus in x for -3
f(x) = 4(-3)^2 + 3(-3) - 11
f (x) = 4(9) -9 - 11
f(x) = 36 - 20
f(x) = 16
7.5. 10.5*5 and divide that by 7
