Answer:
Choice c.
Step-by-step explanation:
The domain of a rational function is found where the denominator of the fraction is equal to 0. These are the values that are NOT allowed. We have to factor the denominator completely to find these values that make the denominator equal 0. In other words, our denominator right now is:
we set each factor equal to 0:
x = 0 or
The left side of that quadratic is the difference of perfect squares, so it factors into the 2 binomials:
(x + 4)(x - 4)
Setting each of those equal to 0 we can solve for the values of x that are not allowed:
If x + 4 = 0, then
x ≠ 4.
If x - 4 = 0, then
x ≠ -4
So the domain for this rational function is:
{x I x ≠ ±4, x ≠ 0},
which is c.
Please find the attached file for a proper understanding of the question given here. The diagram in the file attached is the complete accompanying diagram of the question.
As per that diagram, (which is given)
and we know that (vertically opposite angles).
Thus, the only way ΔDSB ≅ ΔTSR by SAS is when as indicated in the diagram.
Thus, is the correct answer.
Step-by-step explanation:
Volume of cylindrical container
Answer:
$16 per pound
Step-by-step explanation:
We want to find the price per pound.
Therefore, we must divide the cost by the pounds.
We know it costs $144 for 9 pounds of pears. Therefore, $144 is the cost and there are 9 pounds.
Divide.
It costs $16 for each pound of pears.
So firstly, multiply both sides by t:
Next, add both sides by v0, and your answer will be:
