Answer:
All Triangles are closed figure polygons that have three straight sides
Step-by-step explanation:
All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.
1. 100 times larger than
2. 1/10
3. 1,000 times larger than
4. 1,000 times larger than
5. 1/100
6. 1/10
7. 1/10
The answer is 19.6 cm^2
you should find the height of the triangle by heron formula: it will be 9.8
so the area is
good luck
Given that height, h(t) of a tennis ball is modeled by the equation h(t)=<span>-16t^2 + 45t + 7, the time taken for the ball to reach maximum height will found as follows:
at maximum height:
h'(t)=0
but from the equation:
h'(t)=-32t+45=0
solving for t we get
t=45/32
t=1.40625~1.4 seconds
Thus the time taken to reach maximum height is 1.4 seconds
