The correct option is (A) DEF
Explanation:
For similarity, one triangle has to be at least the scaled version of another. In the triangles given above as you can see:
The length of DE ( in DEF) = 5.5
The length of AB (in ABC) = 11 which is 2*(The length of DE ( in DEF))
Likewise
The length of EF( in DEF) = 2.5
The length of BC(in ABC) = 5 which is 2*(The length of EF ( in DEF))
Same goes for the third side.
Hence the correct option is (A) DEF
I think its 900 i’m not sure
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
