Answer: (21,12)
Step-by-step explanation:
We know that
<span>The formula for the area of a quadrilateral with perpendicular diagonals is
</span>A=(0.5)*(D1*D2)
A=58 in²
D1=AC=14.5 in
D2=BD=?
so
D2=2*A/D1-----------> 2*58/14.5-----------> D2=8 in
BD=D2=8 in
the answer is
BD=8 in
Let
x-------> the number of persons in the family
f(x)------> the function represent the cost of living
we know that
The domain of the function would only include positive integers, because the number of persons can not be negative or a fraction
The range of the function would only include positive numbers, because the cost can not be negative
therefore
<u>the answer is the option B</u>
The domain would only include positive integers.
Since 200 is a constant, of x, move 200 out of the integral. 200x+c. Constant is a fixed value that does not change.
