Answer:

230cm²

Step-by-step explanation:

The shape can be split into two shapes horizontally: a triangle and a rectangle.

Area of the rectangle

The area of a rectangle = length × width

In this case, the length is 20cm and the width is 7cm. 20 × 7 = 140cm²

Area of the triangle

The area of a triangle = 1/2 × base × height

In this case, the base is 20cm and the height is 9cm (16cm - 7cm). 1/2 × 20 × 9 = 90cm²

Area of the shape

To find the area of the total shape, we can add 140cm² and 90cm² to get 230cm².

Hope this helps!

A new car was valued at $28,000, and it's value depreciated to $14,000 over the next 3 years. Use the exponential equation for d

kompoz [17]

The exponential equation (in thousands) is:
$V = 28 e^{-rt}$
plug in t=3 yrs, and solve for 'r'.
$14 = 28 e^{-3r} \\ \\ \frac{1}{2} = e^{-3r} \\ \\ ln(\frac{1}{2}) = -3r \\ \\ r = \frac{ln(\frac{1}{2})}{-3} = 0.231 = 23.1%$

Find value of car when t = 10
$V = 28e^{-2.31} = 2.779$
