We'll need to find the 1st and 2nd derivatives of F(x) to answer that question.
F '(x) = -4x^3 - 27x^2 - 48x - 16 You must set this = to 0 and solve for the
roots (which we call "critical values).
F "(x) = -12x^2 - 54x - 48
Now suppose you've found the 3 critical values. We use the 2nd derivative to determine which of these is associated with a max or min of the function F(x).
Just supposing that 4 were a critical value, we ask whether or not we have a max or min of F(x) there:
F "(x) = -12x^2 - 54x - 48 becomes F "(4) = -12(4)^2 - 54(4)
= -192 - 216
Because F "(4) is negative, the graph of the given
function opens down at x=4, and so we have a
relative max there. (Remember that "4" is only
an example, and that you must find all three
critical values and then test each one in F "(x).
Answer:
A. exactly $9.54
Step-by-step explanation:
First add up how much he bought
Sandwich 5.98
drink 2.99
apple 1.49
---------
10.46
Then subtract this from 20
20.00
-10.46
--------------
9. 54
When you get money back, you get exact change.
Answer:
125 degrees.
Step-by-step explanation:
m < CBD = m < A + m < C ( by the External Angle of a Triangle theorem).
= 58 + 67 = 125 degrees.
Answer:
<h2>1.25</h2>
Step-by-step explanation:
5/4 =
1.25
The first number divided by four is the second number. 5 divided by 4 is 5/4, 1 1/4, OR 1.25
Hope that helps!
Answer:
[See Below]
Step-by-step explanation:
✦ First change the improper fractions to decimals:
✧ ⁵⁄₄ = 1.25
✧ -⁹⁄₅ = -1.8
✦ Then divide:
✧ 1.25 ÷ -1.8 = -0.69
So x would be -0.69 in decimal form.
