7.For tire size P225/45R17, give the following: Width(mm): _______________ Aspect Ratio (%): _______________ Height (in.): _____

irakobra [83]

The width is the first numbers.

Width = 225 mm

Aspect ratio is the second number.

Aspect ratio is 45

Aspect ratio is width / height.

You have the ratio and width so you can calculate the height:

Multiply the width by the ratio:

Height = 225 x 0.45 = 101.25 mm

101.25/25.4 = 3.98 inches

The rim

Diameter is the last number

Rim diameter = 17 inches

So the overall height would be approximately 17 + 3.98 + 3.98 = 24.96 inches

Round the answers as needed.

Eli invested $ 330 $330 in an account in the year 1999, and the value has been growing exponentially at a constant rate. The val

Cloud [144]

Answer:

The value of the account in the year 2009 will be $682.

Step-by-step explanation:

The acount's balance, in t years after 1999, can be modeled by the following equation.

$A(t) = Pe^{rt}$

In which A(t) is the amount after t years, P is the initial money deposited, and r is the rate of interest.

$330 in an account in the year 1999

This means that $P = 330$

$590 in the year 2007

2007 is 8 years after 1999, so P(8) = 590.

We use this to find r.

$A(t) = Pe^{rt}$

$590 = 330e^{8r}$

$e^{8r} = \frac{590}{330}$

$e^{8r} = 1.79$

Applying ln to both sides:

$\ln{e^{8r}} = \ln{1.79}$

$8r = \ln{1.79}$

$r = \frac{\ln{1.79}}{8}$

$r = 0.0726$

Determine the value of the account, to the nearest dollar, in the year 2009.

2009 is 10 years after 1999, so this is A(10).

$A(t) = 330e^{0.0726t}$

$A(10) = 330e^{0.0726*10} = 682$

The value of the account in the year 2009 will be $682.
