I belive the answer is the 3rd one
You are correct for all of them,
Precision goes up as you have more decimals. It gives you a more accurate measurement regardless of what it is measuring.
A line graph measures two variables, the X and the Y, and how they change based off of one another
And an educated guess would usually based on previous trends or results
X=-7y+34
x+7y=32
To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32
So the correct answer would be no solution because it's the same problem and it can't equal to different answers.
Answer:
Around 9.8 tiles
Step-by-step explanation:
The formula is x = (6*9)/5.5.
Answer:
After 2 seconds
Step-by-step explanation:
First step is find an equation of velocity:
h(t)=-16t2+64t+112. The velocity function is derivated from position function, so we should do that.
v(t)= h´(t)= -16*2*t+64 ⇒ v(t)= -32t+64.
Now we know the arrow reach the maximun height when this velocity is equal to zero when t>0.
0=-32t+64 ⇒ 32t=64, split each member for 32 ⇒ 
=
t=2. That means after 2 sec. the arrow reach the maximum height
