Answer:
The estimated weight is in the range:
75.6 pounds Weight 92.4 pounds
Step-by-step explanation:
Since, the maximum error is 10%.
Therefore, the maximum and minimum vales will be 10% more and 10% less than 84 pounds, respectively.
For Maximum Limit:
= (1.1)(84 pounds)
= 92.4 pounds
For Minimum Limit:
= (0.9)(84 pounds)
= 75.6 pounds
Hence, the estimated weight is in the range:
75.6 pounds Weight 92.4 pounds

The answer
<span>to eliminate t from the parametric equations x=t^2+3 and y=4t
we have t²= x-3, and then t= sqrt(x-3), but we know that y=4t, which implies t=y/4. We only substitute the value of t by y/4, so </span>t= sqrt(x-3) wich is equivalent to y/4=sqrt(x-3), so at last y= 4 sqrt(x-3). t exactly eliminated.
so the true answer is
<span>D)She should first substitute y for t before solving.</span>

Step-by-step explanation:
<u>Piecewise Function</u>
The given function has a point where its behavior changes. At the left side of x=3 the function is
While at the right side the function is
We need to find the range of h, i.e. the values h takes when x moves along its domain. Let's analyze what values takes h when x decreases without limit.
When x=3
When x increses without limit
As shown, the values of h run from to 5, i.e.
Or, equivalently
