Answer:
Segment A B and Segment Z W
Step-by-step explanation:
we know that
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
In this problem
Sides C D and Y X are congruent,
sides C B and Y Z are congruent,
sides Z W and A B are congruent,
sides A D and X W are congruent
so
ABCD≅WZYX
The corresponding sides are
AB and WZ
BC and ZY
CD and YX
AD and WX
That means
AB ≅ WZ
BC ≅ ZY
CD≅ YX
AD ≅ WX
The corresponding angles are
∠A and ∠W
∠B and ∠Z
∠C and ∠Y
∠D and ∠X
That means
∠A ≅ ∠W
∠B ≅ ∠Z
∠C ≅ ∠Y
∠D ≅ ∠X
therefore
The answer is
Segment A B and Segment Z W
To find f(5) substitute in the equation the x by 5 and evaluate:
Then, f(5) is 17
The correct answer is A. Number of hours worked
Explanation:
In the equation presented, the number of hours worked is the only factor that varies, it is expected the plumber has to work a different number of hours depending on each situation and this affects the final cost as the number of hours is multiplied by $25 (cost of one hour). On the other hand, factors such as the house call charge or the price of an hour for labor are fixed and do not change.
Moreover, in equations, the factor that changes and can affect others is known as the independent variable. This means the number of hours can be classified as the independent variable because this is not fixed and affect other variables including the total cost.
The product of two rational numbers is always rational because (ac/bd) is the ratio of two integers, making it a rational number.
We need to prove that the product of two rational numbers is always rational. A rational number is a number that can be stated as the quotient or fraction of two integers : a numerator and a non-zero denominator.
Let us consider two rational numbers, a/b and c/d. The variables "a", "b", "c", and "d" all represent integers. The denominators "b" and "d" are non-zero. Let the product of these two rational numbers be represented by "P".
P = (a/b)×(c/d)
P = (a×c)/(b×d)
The numerator is again an integer. The denominator is also a non-zero integer. Hence, the product is a rational number.
