The answer should be true
Answer:
x=-0.625
Step-by-step explanation:
24x+15=0
-15 -15
24x=-15
x=-0.625
(1-sin(x))(1+sin(x))=1/1+tan(x^2)
I think the right side is tan^2 x ( the square of tan x)
Left side = 1 - sin^2 x
Right side = 1 / ( 1 + (sin^2 x / cos^2x))
= 1 / (cos^2x + sin^2x) / cos^2 x
Now sin^2 x + cos^2 x = 1 so
this = 1 / 1 / cos^2x
= cos^2x = 1 - sin^2 x = Left side - Proved
Answer: $10988.25
Step-by-step explanation:
From the question, we are told that for the Black Panther trip 420 students were scheduled to go and 15% more students were selected. This means that the total number of students that are going will be:
= 420 + (15% × 420)
= 420 + (0.15 × 420)
= 420 + 63
= 483 students
Since each administration ticket cost 22.75 dollars. The total amount paid for all tickets purchased will be:
= 483 × $22.75
= $10988.25
