The rule for the area of a polygon is as follows:

Area of a Polygon = Apothem x Perimeter ÷ 2

So, add all the of the outside measurements together to find the Perimeter but I don't know where the Apothem in the polygons are.

I hope this gives you some sort of a lead. :)

The initial value of a quantity Q (at year t = 0) is 112.8 and the quantity is decreasing by 23.4% per year. a) Write a formula

Svetach [21]

Answer:

a) $Q(t) = 112.8*(0.766)^{t}$

b) When t = 10, Q = 7.845.

Step-by-step explanation:

The value of a quantity after t years is given by the following formula:

$Q(t) = Q_{0}(1 + r)^{t}$

In which $Q_{0}$ is the initial quantity and r is the rate that it changes. If it increases, r is positive. If it decreases, r is negative.

a) Write a formula for Q as a function of t.

The initial value of a quantity Q (at year t = 0) is 112.8.

This means that $Q_{0} = 112.8$ .

The quantity is decreasing by 23.4% per year.

This means that $r = -0.234$

$Q(t) = 112.8*(1 - 0.234)^{t}$

$Q(t) = 112.8*(0.766)^{t}$

b) What is the value of Q when t = 10?

This is Q(10).

$Q(t) = 112.8*(0.766)^{t}$

$Q(t) = 112.8*(0.766)^{10} = 7.845$

When t = 10, Q = 7.845.

The relation Q is described as a list of ordered pairs, shown below. Q = { (-2, 4), (0, 2), (-1, 3), (4, -2) whats the domain an

tester [92]

Answer:

Domain: {-2,0,-1,4}

Range: {4,2,3,-2}

Step-by-step explanation:

1. Given the The relation Q={ (-2, 4), (0, 2), (-1, 3), (4, -2)}, you can determine the domain and the range as following:

DOMAIN:

The domain is the x-coordinate of each ordered pair. Therefore, you have:

Domain: {-2,0,-1,4}

RANGE:

The range is the y-coordinate of each ordered pair. Therefore, you have:

Range: {4,2,3,-2}
