The vertical segment joining A (1,5) and B (1,1) has been graphed on the number plane. Find the length of the segment.
Alecsey [184]

Answer:

4 units

Step-by-step explanation:

because the points have the same x-coordinate, we just need to subtract the y-coordinates to find the distance.

5 - 1 = 4

therefore, the length of the segment is 4 units.

Robert has available 400 yards of fencing and wishes to enclose a rectangular area. Express the areaAof the rectangle as a funct
solong [7]

Answer:

The answer is below

Step-by-step explanation:

a)Given that the length of fencing available is 400 yards. This means that the perimeter of the rectangle is 400 yards.

the perimeter of a rectangle is given as:

Perimeter = 2(length + width) = 2(l + w)

Hence;

400 = 2(l + w)

200 = l + w

l = 200 - w

The area of a rectangle is given as:

Area = length × width

Area = (200 - w) × w

Area = 200w - w²

b) For a quadratic equation y = ax² + bx + c. it has a maximum at x = -b/2a

Hence, for the area = 200w - w² a=-1, b = 200, the maximum width is at:

w = -b/2a = -200/2(-1) = -200/-2 = 100

A width of 100 yard has the largest area

c) l = 200 - w = 200 - 100 = 100 yards

Area = l × w = 100 × 100 = 10000 yd²

The maximum area is 10000 yd²

Book club A charges $20 for membership and $2 per book rental. Book club B charges $10 for membership and $3 per book rental. Fo
Mrrafil [7]

Given:

Book club A charges $20 for membership and $2 per book rental.

Book club B charges $10 for membership and $3 per book rental.

To find:

The number of books for which the cost be the same at both book clubs.

Solution:

Let x be the number of books.

Book club A charges $20 for membership and $2 per book rental. So, the total cost is

C_1=20+2x             ...(i)

Book club B charges $10 for membership and $3 per book rental. So, the total cost is

C_2=10+3x            ...(ii)

Equating (i) and (ii), we get

10+3x=20+2x

3x-2x=20-10

x=10

The total cost is

C_1=20+2(10)

C_1=20+20

C_1=40

Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.
