The correct answer for the question that is being presented above is this one: "A. Quadrilateral KJFG was rotated 90° counterclockwise around the origin and then translated 8 units down." Quadrilateral KJFG is congruent to quadrilateral K ' J ' F ' G '.
Answer:
-19
Step-by-step explanation:
If c = -4 and y = 3, replace c and y with their corresponding values in the expression, so that the expression will look like this: <em>(-4) - (5 * 3).</em>
Since multiplication comes before subtraction in PEMDAS, you would multiply 5 by 3, which gets you 15.
Now the expression is <em>(-4) - (15).</em> Then, you do the subtraction. -4 - 15 is equal to -19.
Does that help?
The answer to the equation is x<-2
Answer:
A
Step-by-step explanation:
if you take 23 and put it in for p 18+23=41
V=x(8-2x)(10-2x) or expanded
V=x(4x^2-36x+80)
V=4x^3-36x^2+80x
...
If you were to graph the above equation for V(x) you will see a maximum point where the "y" value is maximized, but be careful as V will increase without bound at values of x that are not part of the domain, ie, in this case x<8/2, x<4 to have any meaning...The proper domain of this function is:
x=(0,4), Mathematically finding this point quickly is by differentiating it with respect to x...
dV/dx=12x^2-72x+80, The maximum volume will occur when dV/dx=0 and the x value is within the correct domain...
12x^2-72x+80=0 (using the quadratic formula for ease)
x=(72±√1344)/24, and since x<4
x≈1.472in (to the nearest one thousandth of an inch)
