Expand
f(x)=-1x^2-8x+33
x coordinate of vertex is -b/2a in the form ax^2+bx+c=y
a=-1
b=-8
-(-8)/2(-1)=8/-2=-4
plug back in to get y value
y=-(-4^2)-8(-4)+33
y=-16+32+33
y=49
y value is 49
In probability 2 events are independent if the occurrence of 1 event does not affect the occurrence of the other event. Mathematically, if event A and event B are independent, then 
. For our two events in this problem we have that 
and 
. If these two events are independent, then we should have that,
.A and B are independent events if the probability of A and B is 0.1
Exponential form is when a certain number is raised to the power of a certain number or also known as exponents. Exponents signifies that the base or the number that is being raised to a certain powers will be multiplied a number of times, based on the exponents).
Exponential form is defined as repeated multiplication of the base.
