Answer:
   12.  1 second, 35 ft; 2 seconds, 32 ft
   13.  (t, y) = (1.4 seconds, 37.6 feet)
   14.  37.6 ft; the vertex is the highest point
Step-by-step explanation:
12. You have properly answered question 12.
After 1 second, the height is 35 feet; after 2 seconds, it is 32 feet.
__
13. My method of choice is to plot the graph on a graphing calculator and let it show me the coordinates of the vertex when I highlight that point. (See attached.) The vertex is ...
   (t, y) = (1.4, 37.6)
__
14. The graph is a graph of height when the object is launched with a vertical velocity of 45 ft/s. So, the maximum of the graph will correspond to the maximum height of the object. The vertex is that maximum point, and its y-coordinate is that maximum height.
The maximum height is 37.6 feet.
 
        
             
        
        
        
To perform the following operation, make sure to do the division parts separately and place them back together in the final answer. 
10/2 and x^5/x^2 
5 and using the exponential laws of division X ^m/X^n = X ^ m-n 
The second part evaluates to X^3. 
Putting the terms together we get the final answer, which is 5x^3.
        
             
        
        
        
Answer:
x = 32 in
Step-by-step explanation:
8/34 = x/136
34x = 1088
x = 32 in
 
        
             
        
        
        
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
