Answer:
ok so first lets find the answer to the original question
28+7=35
so lets find which one is equal to 35
7(4+1)=28+7=35 yes
4(7+1)=28+4=32 no
4(7+3)=28+12=40 no
7(4+7)=28+49=77 no
a is the answer 
Hope This Helps!!!
 
        
             
        
        
        
 
There are  10  juice boxes in the cooler altogether.
2  of them are grape.
The first time Jill pulls one out with her eyes closed,
the probability that it's a grape is
                                         2 / 10 .
If that try is successful, then there are  9  boxes left in the cooler,
and one of them is grape.
If she already has one grape, and reaches in again with her eyes 
closed, the probability of pulling out the second grape is
                                        1 / 9 . 
The probability of both events happening in two tries is
                           (2/10) x (1/9) = 2/90 = 1/45  =  (2 and 2/9) percent .
        
                    
             
        
        
        
Answer:
dy/dx = -b/a cot α
Step-by-step explanation:
x² / a² + y² / b² = 1
Take derivative with respect to x.
2x / a² + 2y / b² dy/dx = 0
2y / b² dy/dx = -2x / a²
dy/dx = -b²x / (a²y)
Substitute:
dy/dx = -b²a cos α / (a²b sin α)
dy/dx = -b cos α / (a sin α)
dy/dx = -b/a cot α

Use tangent to find the x.

 = 2863.6253
So, the boat is 2,863.63 feet from the shore.
