Answer:
Option B. The equation has a maximum value with a y-coordinate of -21.
Step-by-step explanation:
The correct quadratic equation is
This is a vertical parabola open downward (the leading coefficient is negative)
The vertex represent a maximum
Convert to vertex form
Factor -3
Complete the square
Rewrite as perfect squares
The vertex is the point (2,-21)
therefore
The equation has a maximum value with a y-coordinate of -21
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:
Add 3x to both sides:
Add 6 to both sides:
Which is of course equivalent to
Divide both sides by 9
So, every number smaller than 2 is part of the solution of this inequality.
Answer:
x = 3
Step-by-step explanation:
Volume of a cylinder formula is
Formula of the sum of the 1st nth term in a Geometric Progression:
Sum = a₁(1-rⁿ)/(1-r), where a₁ = 1st term, r = common ratio and n= rank nth of term (r≠1)
Sum = (-11)[1-(-5⁸)] /[(1-(-5)]
Sum = (-11)(1- 390625)/(6)
SUM = 716,144
