Mr. Nelson is buying property in the shape of a triangle to build a new house. If the property costs $42.50 per square foot, how

julsineya [31]

First, you find the area of the figure. Use the formula a=h(b/2)

a=h(b/2)
a=47(98/2)
a=47(49)
a=2303

Now, you multiply that by $42.50 to find out how much he will pay.

2,303x42.50=97,877.50.

He will pay $97,877.50.

The fish population of Lake Collins is decreasing at a rate of 5% per year. In 2004 there were about 1,350 fish. Write an expone

ad-work [718]

Answer:

Part 1) The exponential function is equal to $y=1,350(0.95)^{x}$

Part 2) The population in 2010 was $992\ fish$

Step-by-step explanation:

Part 1) Write an exponential decay function that models this situation

we know that

In this problem we have a exponential function of the form

$y=a(b)^{x}$

where

y ----> the fish population of Lake Collins since 2004

x ----> the time in years

a is the initial value

b is the base

we have

$a=1,350\ fish$

$b=(100\%-5\%)=95\%=0.95$

substitute

$y=1,350(0.95)^{x}$ ----> exponential function that represent this scenario

Part 2) Find the population in 2010

we have

$y=1,350(0.95)^{x}$

For $x=(2010-2004)=6\ years$

substitute

$y=1,350(0.95)^{6}=992\ fish$

1. Renting a bicycle at a local Bike shop costs $30 for the first day and $10 for each additional day.

Elza [17]

(a) Create a chart of values and write an equation to find the total cost, C in terms of the number of days d.

C = 10d + 20

(b) Use the equation you created in Part (a) to find the cost of renting a bike for 5 days.

C = 10d + 20
C = 10(5) + 20= 50 + 20 = 70

$70 for 5 days
