Answer:
q#1 Option B.2 possible solution is correct option
Q#2 option c. 1 viable solution is correct option.
Step-by-step explanation:
Q#1
y=4+3x+45
as this is a quadratic solution
and we know that when we solve a quadratic equation then it gives two possible solutions
hence option b is the correct option
Q#2
option c is correct option when we solve an quadratic equation it gives two solution one is positive and other is negative as we know that income cannot be negative
hence only one viable solution exists when we solve this
y=4+3x+45 quadratic equation

Step-by-step explanation:
Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
The answer is x=K/b + 2/b.
Answer: Choice D
==========================================================
Explanation:
Let g(t) be the antiderivative of 
. We don't need to find out what g(t) is exactly.
Recall by the fundamental theorem of calculus, we can say the following:
This theorem ties together the concepts of integrals and derivatives to show that they are basically inverse operations (more or less).
So,
From here, we apply the derivative with respect to x to both sides. Note that the 
portion is a constant, so
