The term that is defined as the distance is the raduis.
The best way is to check all answers. lets check answer A first.
Take the equation y > -3x +3 and substitute 2 for x and -5 for y.
(-5)> -3(2) + 3
-5 > -6 + 3
-5 > -3
we know this is not true so A is not the answer. because it is an invalid solution.
Lets check B
(-2)>-3(5) + 3
-2 > -15 +3
-2 > -12
we know this is true so it is a valid solution Now we have to check the other equation with the same point.
y> x +2
5> (-2)+2
5> 0
we know this is true so its a valid solution.
This means B the correct answer.
we are given
1.11, 2.54, 3.97, 5.40, ...
we can see that
first term is 1.11
now, we can find common difference
now, we can find second difference
we can see that
differences are same
so, this is arithematic sequence
now, we can find it's nth term
now, we can simplify it
and we get
............Answer
The answer is the second option 2/5 there are 25 all together divide to make it 5 then there are 2/5 of that five that are girls
Given
h(t)=-16t^2+25t+3
assume h(t) is height measured upwards from ground.
Need h(t)=0 for t>0.
solve
<span>h(t)=-16t^2+25t+3=0
</span>use quadratic formula, A=-16, B=25, C=3
t=(-B +/- sqrt(B^2-4AC))/2A
=-25-sqrt(25^2+192)/(-32)
= {-0.11198, 1.6745} seconds
reject negative root, so
time = 1.6745 seconds.
