Answer:
ax² + bx + c
Step-by-step explanation:
The form of a quadratic equation that is easy to use when finding the maximum or minimum value of the function is ax² + bx + c.
Suppose a quadratic function:
f(x) = 2x² - 8x + 9
Use ( -b/2a , f(-b/2a) ).
-b/2a
a = 2
b = -8
-(-8)/2(2)
8/4
= 2
f(2) = 2(2)² - 8(2) + 9
f(2) = 2(4) - 8(2) + 9
f(2) = 8 - 16 + 9
f(2) = 1
The minimum value of this quadratic function is (2, 1).
It represents a minimum value because a > 0.
Answer:
10m
Step-by-step explanation:
We can set up an equation to solve this.

This equation can be created since we are given two similar sides of both triangles.
Now, cross multiply and simplify to solve for
.

The answer is sensible, and if you put 10 into the same equation from earlier, you will see that it is accurate.
Therefore, the value of
is 10m.
Infinite straight lines could be drawn from a single point in any direction.
