Answer:
Step-by-step explanation:
Let the quadratic function be
The given points must satisfy this function;
Substitute .
Substitute (0,-2)
Substitute (1,-4);
Put equation (2) into equation (1)
Put equation (2) into equation (3)
Add equation (4) and (5)
Divide both sides by 3
Put a=3 in equation 5.
The quadratic function is;
Answer:
The answer to your question is 287.52 u²
Step-by-step explanation:
To calculate the area of a triangle it is necessary to have the base and the high of this figure.
Base = 35 km
height = ?
To calculate the height draw a right triangle and use the trigonometric function sin to find it.
sin Ф =
Opposite side = hypotenuse x sinФ
Opposite side = height = 37 x sin28
= 16.43 km
Calculate the area
Area = (1/2)(35)(16.43)
Area = 287.52 u²
