The answer is c. 23 degrees. 697-360 is 337. 360-337 is 23.
Your problem statement needs a bit of correction:
"<span>Y= -16t^2 +400, where t represents the number OF SECONDS after the camera is dropped. How long will it BE before Kay sees the splash from the camera hitting the water?"
Set y = -16t^2 + 400 = 0. We assume that 400 and 0 represent feet (English system).
Then 16t^2 = 400, and so 25 = t^2. Only the positive square root makes sense here, and that root is 5 (seconds).</span>
Answer:
760ft
Step-by-step explanation:
First you find the volume of the rectangle thing :)
so 14 times 19 times 2 = 532ft
than you need to do the triangle so 20 - 14 (for base length) is 6
so 19 times 6 times 2 = 228ft
now you ad them, so 532 + 228 = 760
Answer:
THE CORRECT OPTION IS C) Δ RST 
Δ UVW ; 
Step-by-step explanation:
i) ∠ WUV = ∠ TRS ( same angle = 32 )
ii) 
;
Hence it is proved that
Δ RST Δ UVW
