You are making a walkway around part of a swimming pool. The dimensions of the swimming pool are 18 and 25, while the dimensions

Answer:

$A = 4x^2 + 86x + 450$

Step-by-step explanation:

Given

$Walkway = x$

$Length = 18$

$Width = 25$

Required:

The area of the swimming pool

Assume the walkway will be on the 4 sides of the swimming pool.

The total length (L) of the swimming pool will be:

$L = 18 + x + x$

$L = 18 + 2x$

The total width (W) will be:

$W = 25 + x + x$

$W = 25 + 2x$

The area (A) is:

$A = L * W$

$A = (18 + 2x) * (25 + 2x)$

Expand bracket

$A = 18 * 25 + 18 * 2x + 25 * 2x + 2x * 2x$

$A = 450 + 36x + 50x + 4x^2$

$A = 450 + 86x + 4x^2$

Reorder

$A = 4x^2 + 86x + 450$

Answer:

3.6

Step-by-step explanation:

Pythagorean theorem:

a^2 + b^2 = c^2

(6 km)^2 + b^2 = (7 km)^2

36 + b^2 = 49

b^2 = 13

b = sqrt(13)

b = 3.6

Answer: 3.6 km

What shape is created by the rotation and what is the

zlopas [31]

Answer:

<u>Option D: A cylinder with a circumference of about 50 units</u>

Step-by-step explanation:

The rest of the question is the attached figure.

The square shown has a perimeter of 32 units. The square is rotated about line k. What shape is created by the rotation and what is the approximate circumference of the base? Circumference of a circle: C = 2πr

===================================================

Given: the perimeter of the square = 32

perimeter of a square is four times the length of its side

So, the side length of square = 32/4 = 8 units

The square is rotated about line k.

So, it will form a cylinder with radius 8 units.

Circumference of a circle = 2 π r

Where, r is the radius of the circle.

Circumference of the base is C = 2 π * 8

∴ C = 16π = 16 * 3.14

∴ C = 50.26548 ≈ 50

The shape is created by the rotation is a cylinder with a circumference of about 50 units.

<u>So, the answer option is D.</u>

Jenny and Lester are running the 100 meter dash. Jenny completes it in 15.2 seconds and Lester completed it in 15.7 seconds. Wha

matrenka [14]

Jenny won the race as she finished the race much more quickly and has greater average speed than Lester.

$\sf \boxed{\sf speed:\frac{distance}{time \ taken} }$

Jenny: distance/time = 100/15.2 = 6.58 m/s = 6.6 m/s

Lester: distance/time = 100/15.7 = 6.37 m/s = 6.4 m/s
