Look at the picture.
To find the area of triangle DBC we need to find its base, x, and its height, h.
Triangle ABC is a right triangle, so using the Pythagorean theorem we can find x.
Now look at triangles ABC and DBH. They both are right triangles and have the same angle α. That means they're similar and their corresponding sides are proportional. The ratio of the side opposite to angle α to the hypotenuse is the same in both triangles - so the ratio of h to 1 is the same as the ratio of 3 to 5.
The base x is 4, the height h is 3/5. Calculate the area:
The area of triangle DBC is 6/5.
Answer:
3/20=6/40=15/100
Step-by-step explanation:
Multiply 3 by 2 to figure out the numerator for /40 and multiply 20 by 5 to figure out the denominator of 15/
The exponential form of the regression 9.68(1409)^x .
An exponential function is described as a characteristic with a nice regular other than 1 raised to a variable exponent. A function is evaluated with the aid of solving at a specific input price. An exponential model can be found when the boom fee and preliminary cost are recognized.
As Harvard commercial enterprise review put it, “The incremental mindset makes a speciality of making something higher, at the same time as the exponential mindset makes a speciality of making something distinct. Incremental is glad with just five percent.
The exponential characteristic is a mathematical feature denoted by using f(x)=exp or e^{x}. Until in any other case specific, the term commonly refers to the fine-valued function of a actual variable, despite the fact that it is able to be extended to the complicated numbers or generalized to other mathematical items like matrices or Lie algebras.
