Throwing a ball, shooting a cannon, diving from a platform and hitting a golf ball are all examples of situations that can be modeled by quadratic functions. ... In many of these situations you will want to know the highest or lowest point of the parabola, which is known as the vertex.
Step-by-step explanation:
(4x-23)2-3=2
(4x-23)(-1)=2
4x-23= -2
4x= -2+23
=21
x=21/4
=5.2
Answer:
Damian swam, ran, and raced his bike for a grand total of 35.30 miles
Step-by-step explanation:
15.01+12.4= 27.41 miles
27.41+7.89= 35.30 miles
It's quadratic
(3x+4)(-2x-3)
expand using FOIL:
-6x^2-14x-12=0
remember -6x^2 term means its quadratic since it's powered by 2
