Question #2

Question #3The answer would be in the attachment below.

Question 4#
The last one was kind of tricky. But, as I saw this attachment, I noticed on how the rectangle was actually 3/4 on the base and for the height, it was 1/2. So by doing this,we need to find the area, and we would multiply these both. 1/2 x 3/4 =  3/8 but by looking at your options, those are not simplified so . . .your answer would be 6/16 because 3x2=6 & 8x2=16.

I really hope this can help you

Answer:
-14
Step-by-step explanation:
Okay first we must simplify the expression. 
so this:(3x^2 + x-2)(x - 5)
becomes this:3x^3-14x^2-7x+10
then we look at the coefficient of x^2 and we see that it's -14 
 
        
                    
             
        
        
        
Answer:
A
Step-by-step explanation:
We are given that: 

And we want to find: 

Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities: 

Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3. 
Our answer is A. 
 
        
             
        
        
        
Answer:
[0, infinity)
Step-by-step explanation:
A square root can only use positive numbers, otherwise it becomes imaginary. A function needs to be real to output real values. Therefore, the domain is everything from 0 onwards.
