Answer:
Step-by-step explanation:
In the first part, we are given the function:
Suppose we make x = tan θ
Then dx = sec² θ.dθ
Since; sec² θ - tan² θ = 1
sec² θ = 1+ tan² θ
∴
Thus; In the first part, Use x = tan θ, where , since the integrand comprise the expression
From the second part by using substitution method;
Answer:
4 is the perfect square factor.
Step-by-step explanation:
52 factors as follows: 52 = 4(13). 4 is a perfect square.
Answer:
C
Step-by-step explanation:
perpendicular lines intersect at a 90 degree angle, meaning it is not answer choice A.
B is incorrect because perpendicular lines intersect, so they can not be parallel.
C is correct because parallel lines never intersect, so perpendicular lines can never be parallel to each other.
D is incorrect because perpendicular lines only intersect at one point and create four consistent right angles.
Answer:
50 feet
Step-by-step explanation:
