Answer:

No; his statement is not reasonable.

Step-by-step explanation:

Do the actual subtraction of 3/16 from 19/24. The LCD is 48.

19/24 less 9/48 becomes 10/48, or 5/24. This is nowhere nearly equal to "16/8 pounds more butter).

Note that 16/8 pounds is actually 2 pounds. So What Adriano says here makes no sense at all.

A correct statement would be: "The weight of butter used by Adriano exceeds the weight of honey used by him by 5/24 lb."

Find the vertices and foci of the hyperbola with equation (x-5)^2/81 -(y-1)^2/144 = 1

vesna_86 [32]

Given the equation of an hyperbola in the form:
$\frac{(x-a)^2}{b^2}- \frac{(y-c)^2}{d^2}=1$
Then the focus of the hyperbola is $(\pm\sqrt {b^2+d^2},0)$
Compute like this:
$\sqrt{81+144}=15$
So the two focus points are $(\pm15,0)$
The vertices are given by the formula: $(\pm a,0)$
We deduce the two vertices of the given hyperbola: $(\pm9,0)$
since $\sqrt{81}=9$
