Answer:
24 cm squared
Step-by-step explanation:
cut the dotted line and move the new triangle to the other side this makes a square 4*6=24 cm squared.
Given:
The number is 
.
To find:
The a+bi form of given number.
Solution:
We have,
It can be written as
![[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bab%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D%5D)
![[\because \sqrt{-1}=i]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B-1%7D%3Di%5D)
Here, real part is missing. So, it can be taken as 0.
So, a = 0 and 
.
Therefore, the a+bi form of given number is 
.

Answer:
Step-by-step explanation:
In 1908, a Model T cost $950. This means that the initial price was $950. The car's price dropped to $280 in the year 1927 due to it's increased efficiency.
The decrease in price is determined by subtracting the current price in 1927 from the initial price in 1908. It becomes
950 - 280 = $670
To determine the percentage decrease in price from 1908 to 1927, we will divide the decrease in price from 1908 to 1927 by the initial price in 1908 and multiply by 100. It becomes
670/950 × 100
= 70.53%
