Answer:
7 seconds
Step-by-step explanation:
Distance of the coin above the water is modeled by the equation
where 
is time taken to cover the distance
Now equating with zero.
So, time taken by the coin to hit the water is 7 seconds.
Answer:
656.25m^3
Step-by-step explanation:
Also 1/2 is equivalent to 0.5
25*17.5*1.5=656.25
Answer:
yes , 33^2 + 56^2 = 65^2 and obtuse
Step-by-step explanation:
<h2><u>Question 3</u></h2>
make use of the Pythagoras theorem
which is :
c^2 = a^2 + b^2
where c is the hypotenuse.
now put the values in the equation
65^2 = 56^2 + 33 ^2
the answer is :
<u>yes , 33^2 + 56^2 = 65^2</u>
<u></u>
<h2><u>Question 4</u></h2>
<u />
note if :
c^2 = a^2 + b^2 ----------- right
c^2 < a^2 + b^2------------ acute
c^2 > a^2 + b^2------------- obtuse
hence :
16 + 30 > 38
therefore its : <u>obtuse </u>
