Answer:
The constant of proportionality is option D i.e 5.
Step-by-step explanation:
Variation:
Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.
- Direct variation
- Inverse variation
Direct Variation:
Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
Example 
where, k is constant of proportionality.
The above given example is of Direct Variation
∴ y = 5 x
∴ k = 5 = constant of proportionality.
Inverse Variation:
Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
Example 
where, k is constant of proportionality.
Answer:
(x, y ) → (x + 2, y - 4 )
Step-by-step explanation:
Compare the coordinates of 2 corresponding points in the original and the image, that is
B(- 5, 4 ) → B'(- 3, 0 )
To translate from B → B'
We require a shift of 2 units right in the x direction and 4 units down in the y direction, that is
(x, y ) → (x + 2, y - 4 ) ← translation rule
Answer: Answer: 1333.25Step-by-step explanation: The area of the rectangle is 23x23 = 529. Area of the square is 804.25. So add them toget her and you get your answer.
Step-by-step explanation: (Same person that answered your other question I have two accounts)
2. $1000/65hrs = $15.38 per hour
3. Assuming that you get time and a half for OT.
$25 x 45hrs + 1.5(20hrs x $25)
= $1125 + $750
=$1875
4. You lose 8 hrs pay. So you only work 32 hrs.
32hrs x $25 = $800
