<span>here are the answer choices
 m∠ABC=32°
 m∠ABC=64°
 m∠ABC=90°
 m∠ABC=128°
</span>∠ ABC<span> is less than 90</span>° so the 3rd and 4th option is out.
The most likely answer is 64°. m∠ABC = 64°
32° x 2 = 64°
        
                    
             
        
        
        
Answer:
the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.
The rate of melting is 1.5inches per hour.  It will take 10 hours at the melting rate given of 1.5 to melt all the snow.
Step-by-step explanation:
the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.
The rate of melting is 1.5inches per hour.
At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start
At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.
 
        
             
        
        
        
We want to evaluate

First we note that the integrand is even (replacing x with -x doesn't fundamentally alter the function being integrated), so this is equal to

The radicand reduces significantly to

so that taking the square root, we simplify the integral to

which is trivially computed with a substitution of  and
 and  :
