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

vredina [299]

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

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

Two different businesses model their profits over 15 years, where x is the year, f(x) is the profits of a garden shop, and g(x)

horsena [70]

Hi there!

$\large\boxed{\text{Choice 4}}$

We can look at each function, f(x) and g(x), to determine which is exponential.

Use slope formula: m = y2-y1/x2-x1

f(x) starts off with a slope at about $1800/year, but becomes about $1100/year.

g(x) starts off with a slope of about $1500/year, but becomes about $1874/year.

Thus, g(x) is exponential, because g(x)'s slope is increasing across the interval.

only 2/3 of the school districts kindergarten teachers are women. if 59 are men, how many kindergarten teachers in all are emplo

Oxana [17]

Answer:

177

Step-by-step explanation:

2/3 are women.

that means the remainder, 1/3, are men.

59 = 1/3 of all kindergarten teachers (3/3 = 1 representing the "whole").

so,

59×3 = 177

is the number of all kindergarten teachers employed by the school district.
