Answer:
0.2 seconds
Step-by-step explanation:
The graph of b(t) = -16t^2 + 5t + 15 is a parabola opening downward.  The maximum value of b(t) occurs at the vertex.  The t-coordinate of the vertex is t = -5 / (2(-16)) = 5/32 = 0.15625 sec ≈ 0.2 sec.   
 
        
                    
             
        
        
        
Answer:
98 π R
Step-by-step explanation:
Surface area of sphere = 4 π R²
 = 2 π R × 2 R
 = 49 π × 2 R
 = 98 π R
 
        
             
        
        
        
The correct answer for the question that is being presented above is this one: "Point E." The p<span>oint that represents the vertex of the marked angle is the point E.

Answer:
<u>Figure A</u>
Step-by-step explanation:
See the attached figure which represents the given options
We are to select the correct pair of triangles that can be mapped to each other using a translation and a rotation about point A.
As shown: point A will map to point L, point R will map to point P and point Q will map to point K. 
we will check the options:
<u>Figure A</u>: the triangle ARQ and LPK can be mapped to each other using a translation and a rotation about point A. 
<u>Figure B: </u> the triangle ARQ and LPK can be mapped to each other using a translation and a reflection about the line RA. 
<u>Figure C:</u> the triangle ARQ and LPK can be mapped to each other using a translation and a reflection about the line QA. 
<u>Figure D:</u> the triangle ARQ and LPK can be mapped to each other using a rotation about point A. 
So, the answer is figure A
<u>The triangle pairs of figure A can be mapped to each other using a translation and a rotation about point A.</u>
