Answer=10 10gram weights
10*10grams=100grams
therefore the weight would be even on both sides
Answer: where's the question
Step-by-step explanation:
Looking at the data it looks like a line. So the answer will be in y+mx+b format.
Knowing it is a line eliminates answers b and c.
looking at options a is says it starts at about .1 when x is zero. We can see this looks pretty close as the left-most dot is below 1 already.
The slope on a is 1/2--> increasing 1 vertically for every 2 horizontally. The pattern mostly follows that rule.
Therefore a (y=1/2x+.1) would be the correct answer
Question:
Find the point (,) on the curve 
that is closest to the point (3,0).
[To do this, first find the distance function between (,) and (3,0) and minimize it.]
Answer:
Step-by-step explanation:
can be represented as: 
Substitute 
for 
So, next:
Calculate the distance between 
and 
Distance is calculated as:
So:
Evaluate all exponents
Rewrite as:
Differentiate using chain rule:
Let
So:
Chain Rule:
Substitute:
Next, is to minimize (by equating d' to 0)
Cross Multiply
Solve for x
Substitute in
Split
Rationalize
Hence:
Answer: 448 dollars
=============================================
Work Shown:
P = 400 is the balance
r = 0.12 is the decimal form of the interest rate
t = 1 is the number of years
Use those values to get the simple interest to be
i = P*r*t
i = 400*0.12*1
i = 48
The amount of interest charged is $48
Add this onto the balance of 400 dollars and the total amount Aaron owes is P+i = 400+48 = 448 dollars.
