D=9,0
Step-by-step explanation:
Multiplies all the vertices bay scale factor 3/2
Find the critical points of
:


All three points lie within
, and
takes on values of

Now check for extrema on the boundary of
. Convert to polar coordinates:

Find the critical points of
:



where
is any integer. There are some redundant critical points, so we'll just consider
, which gives

which gives values of

So altogether,
has an absolute maximum of 65/16 at the points (0, -1/2) and (0, 1/2), and an absolute minimum of 3 at (-1, 0).

Do you want me to graph it
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use FOIL method.
(2x - 10)(x + 3) = 2x*x + 2x*3 + (-10)*x + (-10)*3
= 2x² + 6x - 10x - 30 {Combine like terms}
= 2x² - 4x - 30
(x³ + 1)(x - 4) = x³*x + x³ *(-4) + 1*x + 1*(-4)
= x⁴ - 4x³ + x - 4
(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 + x⁴ - 4x³ + x - 4
Combine like term
= x⁴ - 4x³ + 2x² - 4x + x <u>-30 - 4 </u>
= x⁴ - 4x³ + 2x² - 3x - 34
Answer:
Step-by-step explanation:
First you do the division in parentheses and you get (-3/4*8/1) = -24/4 = -6
The new exercise becomes 2/3 *(-6)*1/3
Next, since there are only multiplication we have to do then in order from left to right so we have
-12/3*1/3 = -12/9
We can simplify by 3 and we get -4/3
