Answer:

15 km

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2 + b^2 = c^2

Draw a triangle with 12 for x direction and 9 for y direction

The distance is the connecting line which is the hypotenuse

12^2 + 9^2 = c^2

144+81 = c^2

225 = c^2

Taking the square root of each side

sqrt(225) = sqrt(c^2)

15 =c

F(x) =5x^2-20x+3 how to find minimum

Leya [2.2K]

Answer:

(2,-17) should be the minimum.

Step-by-step explanation:

The minimum of a quadratic function occurs at $x=-\frac{b}{2a}$ . If a is positive, the minimum value of the function is $f(-\frac{b}{2a})$

$f_{min}x=ax^2+bx+c$ occurs at $x=-\frac{b}{2a}$

Find the value of $x=-\frac{b}{2a}$

x = 2

evaluate f(2).

replace the variable x with 2 in the expression.

$f(2)=5(2)^2-20(2)+3$

simplify the result.

$f(2)=5(4)-20(2)+3$

$f(2)=20-40+3$

$f(2)=-17$

The final answer is -17

Use the x and y values to find where the minimum occurs.
