Answer:
So then after 2 hours we will have 32 grams.
Step-by-step explanation:
For this case we have the followin exponential model:
n(t) is the quantity after t hours, n is the original quantityand t represent the hours and r the rate constant.
For this case we know that n(0) = 2 grams and n(3) = 128 grams and we want to find n(2)=?
From the initial condition we know that n = 2, and we have the model like this:
Now if we apply the other conditionn(3) = 128 we got:
If we divide both sides by 2 we got:
If we apply natural log for both sides we got:
And our model is this one:
And if we replace t = 2 hours we got:
So then after 2 hours we will have 32 grams.
Answer:
<em>C. (7, 0)</em>
Step-by-step explanation:
<u>Circumcenter of a Triangle</u>
The circumcenter is a point where all the tangent lines of the midpoints of the three sides meet.
The coordinates of the vertices of the pool are (3, 3), (11, 3), and (3, −3). Please refer to the image below where the three midpoints are also shown. Since the triangle is right and two of its sides are parallel to the x-axis and the y-axis, the coordinates of the midpoints are very easy to find
Midpoint of (3, 3), (11, 3)=([3+11]/2,[3+3]/2)=(7,3)
Midpoint of (3,3), (3,-3) =([3+3]/2,[3-3]/2)=(3,0)
The intersection of both lines (shown in red) is the point (7,0) which is also the midpoint of (3,-3), (11,3). Thus this point is where all the midpoints meet.
Answer: C. (7, 0)
