We have that
y = 225-16t²
we know that
<span>the ball hit the ground when y=0
the point when y=0 is the x intercept of the graph
so
find the value of t for y=0
y=0
</span>y = 225-16t²------> 0=225-16t²
16t²=225-------> t²=225/16----------> t=√(225/16) -----> t=15/4 sec
t=3.75 sec
the answer is
t=3.75 sec
see the attached figure
Virtually all of the 7 million millionaires in the United States learned how to make smart decisions by doing their homework.
Answer: Option 7.
<u>Explanation:</u>
It is assumed by a lot of people that the life of the people who are very rich is very easy and that they do not have to work so hard. People think that the rich people have always had a bed of roses kind a life for them.
But that is not the reality. Rich people also have to work hard to get success in their life and for that they have to think properly and wisely before making decisions in their life. These people have to make a lot of research and do a lot of home work before making decisions and have to think a lot. It is not very easy for them also.
I think it’s A or D not sure. Hope I helped.
<span>Congruent triangles are
triangles with the same sides and the same measure of angles. You are given
triangle DEF which is similar to triangle FGH. From the figure, side FH is
larger than side DF. So the statement of them being congruent cancels out. Triangle
DEF is smaller in size than triangle FGH. So they are not congruent. The slope
is defined as the rise over run. Side DF has the same slope as side FH. Sides DE
and FE are proportional to sides FG and HG. Only C and D is correct.
